📝 Walkthrough

Walkthrough

Adds Tron support to the Ledger HDWallet integration and expands Ledger webhid transport cases to include Cosmos, Solana, and Thorchain; updates transport types, introduces a new tron module with address/sign and account-path helpers, and bumps package versions and dependencies to 1.62.19 across many packages.

Changes

Cohort / File(s)	Summary
Ledger transport (webhid/webusb) packages/hdwallet-ledger-webhid/src/transport.ts, packages/hdwallet-ledger-webusb/src/transport.ts	Added translateCoinAndMethod cases for new coins (Tron in both; plus Cosmos, Solana, Thorchain in webhid) by importing Ledger app wrappers and binding methods to the transport.
Ledger core transport types packages/hdwallet-ledger/src/transport.ts	Added type import for Trx; extended LedgerTransportCoinType to include "Tron" and mapped "Tron" to MethodsOnly<Trx> in LedgerTransportMethodMap.
Ledger HDWallet implementation packages/hdwallet-ledger/src/ledger.ts	Implemented Tron interfaces: LedgerHDWalletInfo/LedgerHDWallet now implement TronWalletInfo/TronWallet; added _supportsTronInfo/_supportsTron flags; added tronGetAccountPaths, tronNextAccountPath, tronGetAddress, tronSignTx; extended describePath for Tron.
Tron module packages/hdwallet-ledger/src/tron.ts	New module implementing tronGetAddress, tronSignTx, tronGetAccountPaths, tronNextAccountPath with BIP32 path derivation, transport calls, and error handling.
Utility mapping packages/hdwallet-ledger/src/utils.ts	Added slip44 195 -> "Tron" mapping in appNameBySlip44.
Ledger package deps & version packages/hdwallet-ledger/package.json	Bumped package version to 1.62.19; added dependency @ledgerhq/hw-app-trx: ^6.31.9; updated @shapeshiftoss/hdwallet-core constraint.
Monorepo / examples / integrations version bumps lerna.json, integration/package.json, examples/sandbox/package.json, and many packages/*/package.json files (e.g., packages/hdwallet-*.package.json)	Bumped versions from 1.62.18 → 1.62.19 and updated many internal hdwallet dependency constraints from exact pins to caret ^1.62.19.

🎯 3 (Moderate) | ⏱️ ~30 minutes

• Pay attention to:
  • packages/hdwallet-ledger/src/ledger.ts — interface implementations, capability flags, and describePath branching.
  • packages/hdwallet-ledger/src/tron.ts — BIP32 path derivation, transport calls, signing formatting, and error handling.
  • Transport files (webhid, webusb, src/transport.ts) — correct Trx instantiation and method bindings.
  • packages/hdwallet-ledger/package.json — new dependency and version bump consistency.

Poem

🐰 I hopped in code at break of dawn,
Found Tron tucked in slip44's lawn,
Paths derived and signatures sing,
A tiny hop for a Ledger ring,
Thump — new coin sprouted on my lawn 🥕
