Description

Introduces an embeddable swap widget package (@shapeshiftoss/swap-widget) that enables multi-chain token swaps using ShapeShift's aggregation API. This is a standalone React component that can be integrated into third-party applications with minimal configuration.

Key Features

  • Multi-chain Support: Supports 17+ chains including Ethereum, Arbitrum, Optimism, Polygon, Base, Avalanche, BSC, Gnosis, Bitcoin, Litecoin, Dogecoin, Bitcoin Cash, Cosmos, THORChain, MAYAChain, and Solana
  • DEX Aggregation: Fetches quotes from multiple DEXs/aggregators: THORChain, MAYAChain, CoW Swap, 0x, 1inch, Portals, Chainflip, Jupiter, Bebop, Relay, ButterSwap, ArbitrumBridge
  • EVM Swap Execution: Direct swap execution for EVM chains when wallet is connected via walletClient prop
  • Non-EVM Redirect: Graceful redirect to app.shapeshift.com for non-EVM swaps (BTC, SOL, Cosmos, etc.)
  • Built-in Wallet Connection: Optional RainbowKit integration via enableWalletConnection prop
  • Theming: Dark/light mode support with full theme customization (colors, fonts, border radius)
  • Asset Filtering: allowedChainIds, disabledChainIds, allowedAssetIds, disabledAssetIds props
  • Fixed Receive Address: defaultReceiveAddress prop for locking destination address
  • Performance Optimizations: Request throttling with p-queue, virtualized token list with react-virtuoso
  • Mobile Responsive: Designed for both desktop and mobile viewports

Components

  • SwapWidget - Main entry point
  • TokenSelectModal - Virtualized token selector with search
  • QuotesModal - Compare quotes from multiple swappers
  • SettingsModal - Slippage and receive address configuration
  • AddressInputModal - External receive address input
  • WalletProvider - RainbowKit wallet connection wrapper

API Hooks

  • useAssets / useAssetById / useAssetSearch / useAssetsByChainId - Asset data fetching
  • useChains - Chain metadata
  • useBalances - Wallet balance fetching (EVM)
  • useMarketData - USD price data
  • useSwapRates - Rate/quote fetching with throttling
  • useSwapQuote - Full quote fetching for execution

Deployment

  • Deployed to widget.shapeshift.com via Railway
  • Standalone Dockerfile for containerized deployment
  • Independent package with own dependencies (React 18, wagmi, viem, RainbowKit)

Risk

Low - This is a new standalone package that does not affect the main web application.

Testing

Engineering

  1. Run yarn dev:swap-widget to start the demo app
  2. Test token selection, quote fetching, and swap execution
  3. Verify EVM swaps work with connected wallet
  4. Verify non-EVM assets redirect to app.shapeshift.com
  5. Test theming (dark/light mode)
  6. Test mobile responsiveness

Operations

  • 🏁 My feature is behind a flag and doesn't require operations testing (yet)

This is a standalone widget package and doesn't affect the main app.

Screenshots

Widget is deployed at: https://widget.shapeshift.com

📝 Walkthrough

Walkthrough

Adds a new private package @shapeshiftoss/swap-widget (types, hooks, API client, components, styles, demo, build/deploy, Vite/TS configs, Docker), updates root package.json (script + rainbowkit dependency), adds railway deploy config, and fixes two swapper import paths. No behavioral changes to existing runtime code.

Changes

Cohort / File(s) Summary

API client
\packages/swap-widget/src/api/client.ts``
ApiClient factory exposing getAssets, getRates, getQuote with baseUrl/apiKey, timeout/abort behavior, and 2xx response enforcement.
Utilities
\packages/swap-widget/src/utils/addressValidation.ts`, `packages/swap-widget/src/utils/redirect.ts``
Multi-chain address validators and format hints; ShapeShift trade URL builder, redirect helper, chain detection, and widget execution gate.
Data & market hooks

Poem

🐰 I hopped through code and found a nest,
Widgets, modals, styles dressed best,
Quotes and tokens in a row,
Wallets hum, the balances grow,
The rabbit nods — merge and rest.

- Around line 128-150: The walletClient property in the SwapWidgetProps type is
currently typed as unknown; change it to use viem's WalletClient type so
consumers get proper type inference and EVM swap execution support: import the
WalletClient type from 'viem' (or the correct viem export) and replace
walletClient?: unknown with walletClient?: WalletClient in the SwapWidgetProps
definition, updating any related usage or exports to reflect the new type.

Handle errors gracefully with meaningful messages
Don't silently catch and ignore exceptions
Log errors appropriately for debugging
Provide fallback behavior when possible
Use appropriate data structures for the task
Never add code comments unless explicitly requested
When modifying code, do not add comments that reference previous implementations or explain what changed. Comments should only describe the current logic and functionality.
Use meaningful names for branches, variables, and functions
Always run yarn lint --fix and yarn type-check after making changes
Avoid let variable assignments - prefer const with inline IIFE switch statements or extract to functions for conditional logic

**/*.{ts,tsx}

📄 CodeRabbit inference engine (CLAUDE.md)

**/*.{ts,tsx}: Avoid useEffect where practical - use it only when necessary and following best practices
Avoid 'any' types - use specific type annotations instead
For default values with user overrides, use computed values (useMemo) instead of useEffect - pattern: userSelected ?? smartDefault ?? fallback
When function parameters are unused due to interface requirements, refactor the interface or implementation to remove them rather than prefixing with underscore
Sanitize data before displaying to prevent XSS
Memoize aggressively - wrap component variables in useMemo and callbacks in useCallback where possible
For static JSX icon elements (e.g., <TbCopy />) that don't depend on state/props, define them as constants outside the component to avoid re-renders instead of using useMemo
Account for light/dark mode using useColorModeValue hook
Account for responsive mobile designs in all UI components
When applying styles, use the existing standards and conventions of the codebase
Use Chakra UI components and conventions
All copy/text must use translation keys - never hardcode strings
Use the translation hook: useTranslate() from react-polyglot
Use useFeatureFlag('FlagName') hook to access feature flag values in components
Prefer type over interface for type definitions
Use strict typing - avoid any
Use Nominal types for domain identifiers (e.g., WalletId, AccountId)
Import types from @shapeshiftoss/caip for chain/account/asset IDs
Use useAppSelector for Redux state
Use useAppDispatch for Redux actions
Memoize expensive computations with useMemo
Memoize callbacks with useCallback

📓 Common learnings
Learnt from: NeOMakinG
Repo: shapeshift/web PR: 10323
File: src/components/ButtonWalletPredicate/ButtonWalletPredicate.tsx:7-7
Timestamp: 2025-08-27T09:47:06.275Z
Learning: In shapeshift/web project, NeOMakinG consistently prefers to defer UI/UX improvements and refactoring work (like the Drawer.Close hack fix in ButtonWalletPredicate.tsx) to follow-up PRs rather than expanding the scope of feature PRs, even when the improvements would enhance robustness.
Learnt from: NeOMakinG
Repo: shapeshift/web PR: 10231
File: src/components/AssetSearch/components/AssetList.tsx:2-2
Timestamp: 2025-08-08T15:00:49.887Z
Learning: Project shapeshift/web: NeOMakinG prefers avoiding minor a11y/UI nitpicks (e.g., adding aria-hidden to decorative icons in empty states like src/components/AssetSearch/components/AssetList.tsx) within feature PRs; defer such suggestions to a follow-up instead of blocking the PR.
Learnt from: NeOMakinG
Repo: shapeshift/web PR: 10231
File: src/components/MultiHopTrade/components/TradeInput/components/HighlightedTokens.tsx:14-14
Timestamp: 2025-08-08T15:00:22.321Z
Learning: In shapeshift/web reviews for NeOMakinG, avoid nitpicks to change deep-relative imports to '@/…' alias paths within feature/non-refactor PRs; defer such style-only changes to a dedicated follow-up refactor unless they fix an issue.
Learnt from: NeOMakinG
Repo: shapeshift/web PR: 10376
File: packages/contracts/src/viemClient.ts:39-40
Timestamp: 2025-08-27T09:51:36.901Z
Learning: NeOMakinG confirmed that issues flagged by CodeRabbit that predate the PR changes and are unrelated to the PR's core objective should be addressed separately, not within the current PR scope.

Repo: shapeshift/web PR: 10418
File: src/plugins/walletConnectToDapps/components/header/WalletConnectToDappsHeaderButton.tsx:0-0
Timestamp: 2025-09-08T22:00:48.005Z
Learning: gomesalexandre dismissed an aria-label accessibility suggestion with "meh" in PR `#10418` for WalletConnectToDappsHeaderButton.tsx, consistent with the team's pattern of deferring minor a11y improvements to follow-up PRs rather than expanding feature PR scope.
Learnt from: gomesalexandre
Repo: shapeshift/web PR: 11170
File: patches/@shapeshiftoss+bitcoinjs-lib+7.0.0-shapeshift.0.patch:9-19
Timestamp: 2025-11-25T21:43:10.838Z
Learning: In shapeshift/web, gomesalexandre will not expand PR scope to fix latent bugs in unused API surface (like bitcoinjs-lib patch validation methods) when comprehensive testing proves the actual used code paths work correctly, preferring to avoid costly hdwallet/web verdaccio publish cycles and full regression testing for conceptual issues with zero runtime impact.
Learnt from: gomesalexandre
Repo: shapeshift/web PR: 10458
File: src/plugins/walletConnectToDapps/components/modals/EIP712MessageDisplay.tsx:46-59
Timestamp: 2025-09-10T15:34:54.593Z
Learning: After extensive testing by gomesalexandre in PR `#10458`, dApps do not send EIP-712 domain.chainId as hex or bigint values in practice. The simple String(domain.chainId) conversion is sufficient for real-world usage in WalletConnect dApps structured signing.

Repo: shapeshift/web PR: 10222
File: package.json:202-202
Timestamp: 2025-08-08T20:16:12.898Z
Learning: In shapeshift/web, the semver package must be included in dependencies (not devDependencies) because hdwallet packages have transient dependencies that require semver but don't ship it themselves. This ensures semver is available at runtime for hdwallet functionality.

It forces gridplus-sdk's transitive bs58check dependency from 4.0.0 down to 2.1.2 because bs58check 4.0.0 breaks legacy address validation (due to bs58 v6.0.0 and noble/hash vs 2.1.2's bs58 v4.0.0 and create-hash).

Learning: In shapeshift/web package.json, the resolution "gridplus-sdk/bs58check": "2.1.2" is intentional and must not be removed. It forces gridplus-sdk's transitive bs58check dependency from 4.0.0 down to 2.1.2 because bs58check 4.0.0 breaks legacy address validation (due to bs58 v6.0.0 and noble/hash vs 2.1.2's bs58 v4.0.0 and create-hash).

🔇 Additional comments (10)
packages/swap-widget/package.json (4)

1-16: LGTM!

Package metadata and scripts are well-configured for a standalone ESM TypeScript widget with Vite.


17-27: LGTM! Dependencies properly aligned with monorepo.

  • viem: 2.40.3 correctly pinned to match root
  • wagmi: ^2.9.2 matches root constraint
  • @tanstack/react-query: ^5.69.0 and react-virtuoso: ^4.7.11 match root
  • npm: protocol for @shapeshiftoss/* packages is appropriate for standalone deployment

28-37: React types vs peerDependencies mismatch - minor note.

The @types/react and @types/react-dom are pinned to ^19.0.0, but peerDependencies allow >=18.0.0. If consumers integrate this widget with React 18, they may see type mismatches during development.

Since the widget is deployed standalone (via Docker/Railway) and React 19 was intentionally chosen for development per your previous comment, this is acceptable. Just noting for awareness if the widget is later consumed as a library.


38-41: LGTM!

Flexible peer dependencies (>=18.0.0) appropriately allow consumers to use React 18 or 19.

packages/swap-widget/src/types/index.ts (6)

1-30: LGTM!

Imports are well-organized, leveraging existing utilities from @shapeshiftoss/caip and @shapeshiftoss/utils as requested in previous reviews. Re-exporting AssetId and ChainId types provides a clean public API surface.


32-48: Verify: Local SwapperName enum vs importing from @shapeshiftoss/swapper.

A previous review comment indicated this was fixed to import SwapperName from @shapeshiftoss/swapper, but the code defines a local enum. If this is intentional for decoupling the widget from app internals, consider adding a brief comment explaining the rationale to prevent future confusion, and ensure this enum stays in sync with the canonical definition.


152-188: LGTM!

Response types are well-structured widget-specific DTOs that appropriately map to the API response shapes. The flexibility in QuoteResponse accommodates different swapper backend formats.


190-221: LGTM!

Chain ID constants are well-organized by chain type and properly leverage constants from @shapeshiftoss/caip rather than hardcoding values. The as const assertions enable proper type narrowing.


223-247: LGTM!

Chain utility functions correctly leverage fromChainId from @shapeshiftoss/caip and CHAIN_NAMESPACE for consistent chain type detection. The getChainType function has a sensible fallback to 'other' for unknown namespaces.


249-264: LGTM!

Formatting utilities properly leverage fromBaseUnit and toBaseUnit from @shapeshiftoss/utils. The formatAmount function provides sensible display formatting with locale support and a < 0.0001 fallback for very small amounts. The truncateAddress function handles the common case well for EVM-style addresses.

Fixes bug where customReceiveAddress and defaultReceiveAddress props were being
ignored during swap execution. The getQuote call was hardcoding walletAddress
instead of using the computed effectiveReceiveAddress.

Addresses CodeRabbit review comment.

Bug Fix - receiveAddress using walletAddress instead of effectiveReceiveAddress

Fixed the getQuote API call in SwapWidget.tsx that was incorrectly using walletAddress for receiveAddress instead of effectiveReceiveAddress. This bug meant that customReceiveAddress and defaultReceiveAddress props were being ignored during swap execution.

- receiveAddress: walletAddress,
+ receiveAddress: effectiveReceiveAddress || walletAddress,

Also added effectiveReceiveAddress to the useCallback dependency array.

Previously Fixed (11 items already addressed)

All actionable comments from the first CodeRabbit review were already fixed in commit 666f219:

  • package.json: Removed react/react-dom from dependencies
  • package.json: Aligned viem (2.40.3) and wagmi (^2.9.2) versions
  • SwapWidget.tsx: Derived nativeCurrency from chain metadata
  • SwapWidget.tsx: Wait for approval tx confirmation before swap
  • useSwapQuote.ts: Added slippage to queryKey
  • client.ts: Added timeout handling with AbortController
  • AddressInputModal.tsx: Added tabIndex and useEffect keydown listener
  • useMarketData.ts: Added timeout to proxy availability check
  • addressValidation.ts: Wrapped switch cases in braces
  • README.md: Wrapped bare URL in angle brackets
  • AddressInputModal.css: Replaced hardcoded color with CSS variable

Remaining Items (Deferred)

Low Priority - Empty rpcUrls fallback: The fallback chain creation uses rpcUrls: { default: { http: [] } } which could break createPublicClient for unsupported chains. However, all major supported chains are in VIEM_CHAINS_BY_ID, making this an edge case. Per @gomesalexandre's review: "from here feel free to merge, and/or cleanup in this PR or follow-ups"

Nitpick Comments (25)

These are all code quality suggestions (memoization, i18n, typing, DRY improvements) that are marked as non-blocking. Can be addressed in follow-up PRs as time permits.

Additional CodeRabbit Comments Addressed

Fixed in Commit 3b95030

1. walletClient typed as unknown instead of WalletClient (types/index.ts)

  • Changed walletClient?: unknown to walletClient?: WalletClient
  • Imported WalletClient type from viem
  • Provides proper type inference for consumers

2. createWagmiConfig missing explicit return type (config/wagmi.ts)

  • Added WagmiConfig type alias: type WagmiConfig = WagmiProviderProps['config']
  • Added explicit return type annotation to createWagmiConfig
  • Removed unsafe double assertions (as unknown as Parameters<typeof WagmiProvider>[0]['config']) in:
    • App.tsx (demo)
    • WalletProvider.tsx

3. Updated InternalWalletProvider children callback type (WalletProvider.tsx)

  • Changed from (walletClient: unknown) => ReactNode to (walletClient: WalletClient | undefined) => ReactNode
  • Consistent typing throughout the component

304-310: Fallback chain has empty rpcUrls which could break createPublicClient.

This issue was previously flagged. The fallback chain object uses rpcUrls: { default: { http: [] } }, which would cause waitForTransactionReceipt to fail for chains not in VIEM_CHAINS_BY_ID. While all documented EVM chains are currently covered, there's no validation preventing unsupported chains from reaching this path.

🧹 Nitpick comments (2)
packages/swap-widget/src/components/SwapWidget.tsx (2)

116-123: Module-level QueryClient is shared across all widget instances.

Creating the QueryClient at module level means all SwapWidget instances share the same cache, which could cause issues if multiple widgets are rendered with different apiBaseUrl or apiKey configurations. Consider creating the QueryClient inside each wrapper component or passing it as a prop for better isolation.

♻️ Suggested approach
- const queryClient = new QueryClient({
-   defaultOptions: {
-     queries: {
-       refetchOnWindowFocus: false,
-       staleTime: 30_000,
-     },
-   },
- })
+ const createQueryClient = () =>
+   new QueryClient({
+     defaultOptions: {
+       queries: {
+         refetchOnWindowFocus: false,
+         staleTime: 30_000,
+       },
+     },
+   })

// Then in SwapWidgetWithExternalWallet:
  const SwapWidgetWithExternalWallet = (props: SwapWidgetProps) => {
+   const [queryClient] = useState(() => createQueryClient())
    // ...
  }

390-393: Consider extracting the balance refetch delay to a named constant.

The 3000ms timeout is a magic number. Extracting it to a named constant would improve readability and make it easier to tune if needed.

♻️ Suggested change
+ const BALANCE_REFETCH_DELAY_MS = 3000
+
  // In handleExecuteSwap:
  setTimeout(() => {
    refetchSellBalance?.()
    refetchBuyBalance?.()
- }, 3000)
+ }, BALANCE_REFETCH_DELAY_MS)

Type guards checking for missing chainId in these handlers (like `if (!evmNetworkIdHex) return`) are solely for TypeScript compiler satisfaction, not real runtime edge cases.

Learning: In the RFOX GenericTransactionDisplayType flow in src/components/Layout/Header/ActionCenter/components/GenericTransactionActionCard.tsx, the txHash is always guaranteed to be present according to NeOMakinG, so defensive null checks for txLink are not needed in this context.

Timestamp: 2025-08-11T09:46:41.060Z
Learning: In the shapeshift/web repository, the display cache logic for trade quotes (using `selectUserAvailableTradeQuotes` and `selectUserUnavailableTradeQuotes`) is intentionally kept the same between `TradeInput.tsx` and `TradeQuotes.tsx` components. The `hasQuotes` computation in `TradeInput.tsx` uses these display cache selectors by design, matching the pattern used in `TradeQuotes.tsx`.

Learning: In the ShapeShift web codebase, the following are stable references and do not need to be included in useCallback/useMemo dependency arrays:
- `navigate` from `useBrowserRouter()` hook
- Modal control objects (like `walletDrawer`) from `useModal()` hook (including their `isOpen`, `close`, and `open` methods)
- These are backed by stable context providers

Learning: When reviewing bug fixes, especially in shapeshift/web, prefer minimal changes that fix correctness over introducing broader refactors or quality-of-life improvements (e.g., extracting duplicated logic) unless such improvements are essential to the fix. Apply this guideline broadly to TSX files and related components, not just the specific location, to keep changes focused and maintainable.

838-883: LGTM!

The wrapper components are well-structured with proper memoization of the API client and clean separation between external wallet and internal wallet connection flows.


215-239: LGTM!

Event handlers are properly memoized with useCallback and correctly clear the selected rate when assets change.


196-198: LGTM!

The effectiveReceiveAddress correctly respects the priority chain: customReceiveAddress → defaultReceiveAddress → walletAddress. The quote request on line 286 properly uses effectiveReceiveAddress || walletAddress to ensure custom receive addresses are honored.

Also applies to: 281-289


291-302: LGTM!

The native currency is now correctly derived from chain metadata via getBaseAsset(), addressing the previous issue with hardcoded ETH values. The fallback to ETH defaults is appropriate for edge cases.


331-343: LGTM!

The approval transaction now correctly waits for confirmation via waitForTransactionReceipt() before proceeding with the swap transaction.

In `@packages/swap-widget/src/config/wagmi.ts`:
- Around line 40-49: The double type assertion on the return of
createWagmiConfig is unnecessary; remove the trailing "as unknown as
WagmiConfig" and return the result of getDefaultConfig(...) directly so
TypeScript can validate the returned Config matches the WagmiConfig type (keep
the function signature as returning WagmiConfig and reference createWagmiConfig
and getDefaultConfig to locate the change).

423-437: Same as any type assertion issue as WalletProvider.

Line 429 uses config as any which bypasses TypeScript's type checking. This is the same issue flagged in WalletProvider.tsx.

Per past review comments, this was supposed to be addressed in commit 3b95030 by adding explicit return types to createWagmiConfig. However, the as any assertions remain in both files.

🧹 Nitpick comments (8)
packages/swap-widget/src/types/index.ts (3)

229-232: getEvmNetworkId may produce invalid results for non-EVM chain IDs.

This function parses chainReference to an integer without validating that the chainId is actually an EVM chain. If called with a non-EVM chainId (e.g., a Cosmos chain), it will return an unexpected/invalid network ID.

Consider adding validation or documenting the precondition:

♻️ Suggested fix with validation
 export const getEvmNetworkId = (chainId: string): number => {
+  if (!isEvmChainId(chainId)) {
+    throw new Error(`Expected EVM chainId but received: ${chainId}`)
+  }
   const { chainReference } = fromChainId(chainId as ChainId)
   return parseInt(chainReference, 10)
 }

224-248: Consider adding input validation or error handling for chain utility functions.

The as ChainId type assertions bypass TypeScript's type checking. If an invalid chainId string is passed, fromChainId will throw at runtime. For a public API surface, consider:

  1. Adding a type guard to validate the input, or
  2. Wrapping in try-catch with meaningful error messages

This is a minor concern given these utilities are likely called with controlled inputs from the widget's internal state.


33-49: Consider importing SwapperName from @shapeshiftoss/swapper to reduce duplication.

The local SwapperName enum intentionally excludes the Test swapper, providing decoupling for the widget package. However, maintaining a separate copy creates a maintenance burden—when new swappers are added to the main package, this enum must be manually updated as well.

Rather than duplicating the enum, consider adding @shapeshiftoss/swapper as a dependency (or optional peer dependency) and importing SwapperName, then re-exporting only the production swappers. This ensures the widget stays in sync with the swapper registry without manual duplication.

Alternatively, if decoupling is a hard requirement, document why the local copy is necessary to clarify this is intentional rather than an oversight.

packages/swap-widget/src/components/WalletProvider.tsx (2)

29-45: Unsafe as any type assertion on line 37.

The config as any bypasses TypeScript's type checking. Per coding guidelines, any should be avoided. This appears related to the same type incompatibility between createWagmiConfig return and WagmiProvider's expected config type.

Consider using the same explicit typing approach or documenting why this assertion is necessary.

♻️ Suggested approach
-    <WagmiProvider config={config as any}>
+    <WagmiProvider config={config}>

If the types are truly incompatible, add a comment explaining why and consider creating a proper type adapter.


47-111: Hardcoded strings should use translation keys for i18n.

Lines 80, 92, and 103 contain hardcoded English strings ("Connect", "Wrong network"). Per coding guidelines, all copy/text must use translation keys.

This can be deferred to a follow-up per learnings about NeOMakinG's preference for keeping PRs focused.

packages/swap-widget/src/demo/App.tsx (3)

96-99: applyPreset should be wrapped in useCallback.

Per coding guidelines, functions that could be passed as props or used as dependencies should be memoized with useCallback.

♻️ Suggested fix
- const applyPreset = (preset: (typeof THEME_PRESETS)[0]) => {
-   setDarkColors(preset.dark)
-   setLightColors(preset.light)
- }
+ const applyPreset = useCallback((preset: (typeof THEME_PRESETS)[0]) => {
+   setDarkColors(preset.dark)
+   setLightColors(preset.light)
+ }, [])

124-128: Clipboard API promise rejection is unhandled.

navigator.clipboard.writeText can reject (e.g., if clipboard permission is denied). The promise rejection is silently ignored.

♻️ Suggested fix
- navigator.clipboard.writeText(code).then(() => {
-   setCopied(true)
-   setTimeout(() => setCopied(false), 2000)
- })
+ navigator.clipboard.writeText(code).then(() => {
+   setCopied(true)
+   setTimeout(() => setCopied(false), 2000)
+ }).catch((error) => {
+   console.error('Failed to copy to clipboard:', error)
+ })

130-136: Event handlers should be wrapped in useCallback.

handleSwapSuccess and handleSwapError are recreated on every render and passed as props to SwapWidget. Per coding guidelines, wrap these in useCallback.

♻️ Suggested fix
- const handleSwapSuccess = (txHash: string) => {
-   console.log('Swap successful:', txHash)
- }
-
- const handleSwapError = (error: Error) => {
-   console.error('Swap failed:', error)
- }
+ const handleSwapSuccess = useCallback((txHash: string) => {
+   console.log('Swap successful:', txHash)
+ }, [])
+
+ const handleSwapError = useCallback((error: Error) => {
+   console.error('Swap failed:', error)
+ }, [])

Timestamp: 2025-11-19T16:59:50.569Z
Learning: In src/context/WalletProvider/*/components/Connect.tsx files across the ShapeShift web codebase, the established pattern for handling null/undefined adapter from getAdapter() is to simply check `if (adapter) { ... }` without an else clause. All wallet Connect components (Coinbase, Keplr, Phantom, Ledger, MetaMask, WalletConnectV2, KeepKey, Vultisig) follow this pattern—they reset loading state after the if block but do not show error messages when adapter is null. This is an intentional design decision and should be maintained for consistency.

Learning: In WalletConnectedMenu.tsx's handleReconnectWallet handler, gomesalexandre prefers throwing an error for unsupported wallet types in the default case rather than gracefully handling with a fallback. His reasoning: "if we have a problem here, we have bigger problems" - only supported wallets (KeepKey, Ledger, MetaMask, Coinbase, Phantom) should reach the reconnect flow when disconnected/locked, so encountering an unsupported type indicates a larger architectural issue that should be surfaced explicitly rather than masked with graceful degradation.

Learning: When reviewing bug fixes, especially in shapeshift/web, prefer minimal changes that fix correctness over introducing broader refactors or quality-of-life improvements (e.g., extracting duplicated logic) unless such improvements are essential to the fix. Apply this guideline broadly to TSX files and related components, not just the specific location, to keep changes focused and maintainable.

Learning: In the ShapeShift web codebase, when converting bignumber.js BigNumber values, prefer using .toFixed() over .toString() unless there's a specific reason to use .toString(). The .toFixed() method avoids exponential notation while preserving precision, which is especially important for input field synchronization and display purposes.

Learning: In BigNumber operations within the ShapeShift codebase, floating point literals like 0.01 should always be passed as strings like '0.01' to maintain precision. This applies to all BigNumber methods including .times(), .div(), .plus(), and .minus().

Learning: In src/components/Modals/Send/hooks/useSendDetails/useSendDetails.tsx, within the handleInputChange function, use .toFixed() without arguments (not .toString()) when converting BigNumber amounts for input field synchronization. This avoids exponential notation in the input while preserving precision for presentational components like <Amount.Crypto /> and <Amount.Fiat /> to format appropriately.

Learning: In the ShapeShift web repository vite.config.mts, the commonjsOptions.exclude configuration using bare package name strings like ['shapeshiftoss/caip', 'shapeshiftoss/types'] works correctly for excluding specific packages from CommonJS transformation, despite theoretical concerns about module ID matching patterns.

Learning: In shapeshift/web package.json, the resolution "gridplus-sdk/bs58check": "2.1.2" is intentional and must not be removed. It forces gridplus-sdk's transitive bs58check dependency from 4.0.0 down to 2.1.2 because bs58check 4.0.0 breaks legacy address validation (due to bs58 v6.0.0 and noble/hash vs 2.1.2's bs58 v4.0.0 and create-hash).

Learning: In the shapeshift/web codebase, local constants defined inline (especially in React components) are typically kept in camelCase rather than UPPER_SNAKE_CASE to avoid unnecessary memoization, following a pragmatic approach that prioritizes performance over strict naming conventions.

Timestamp: 2025-09-16T08:47:31.440Z
Learning: In WalletConnect dApps createApprovalNamespaces logic, required namespaces have different semantics than optional namespaces. Required namespaces are validated upfront in the UI - users cannot proceed without accounts for all required chains, and required chains are always selected and unselectable. Therefore, additional filtering by selectedChainIds is unnecessary for required namespaces since the validation flow guarantees they will be supported and selected.

Learning: In packages/chain-adapters/src/**/*ChainAdapter.ts files, the getName() method uses the pattern `const enumIndex = Object.values(ChainAdapterDisplayName).indexOf(ChainAdapterDisplayName.XXX); return Object.keys(ChainAdapterDisplayName)[enumIndex]` to reverse-lookup the enum key from its value. This is the established pattern used consistently across almost all chain adapters (Bitcoin, Ethereum, Litecoin, Dogecoin, Polygon, Arbitrum, Cosmos, etc.) and should be preserved for consistency when adding new chain adapters.

This difference is validated by on-chain simulation testing and is intentional.

129-151: LGTM!

The SwapWidgetProps type is well-structured with proper typing for walletClient as WalletClient from viem, and uses nominal types (ChainId, AssetId) as per coding guidelines.


184-184: LGTM!

Using viem's erc20Abi directly and re-exporting as ERC20_ABI is correct, as resolved in past reviews.


191-222: LGTM!

Chain ID constants correctly leverage @shapeshiftoss/caip exports as per past review resolutions.

packages/swap-widget/src/config/wagmi.ts (1)

1-33: LGTM!

The chain configuration and type exports are well-structured. The SUPPORTED_CHAINS array is properly typed with as const for type inference.

packages/swap-widget/src/components/WalletProvider.tsx (1)

12-12: Module-level QueryClient is shared across all component instances.

While this works for client-side only rendering (ssr: false), it means all widget instances share the same query cache. This is generally acceptable for this use case but worth documenting.

packages/swap-widget/src/demo/App.tsx (1)

14-16: Module-level configuration is appropriate for this demo.

The WalletConnect project ID is intentionally public (client-side SDK requirement), and module-level QueryClient is acceptable for client-only rendering.
