What protocols, transaction types, wallets or contract interactions might be affected by this PR?

Low, under flag and blatant omission

Testing

• All second-class chains appear under chain selection assuming flag on
• With a wallet that doesn't support said chain (e.g MM), native assets are visible under popuular assets when filtering by second-class chain

Engineering

Operations

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

Summary by CodeRabbit

• New Features

  • Expanded popular assets list to surface native assets from additional blockchains (HyperEVM, Monad, Plasma, Sui, Tron), improving discoverability when filtering by chain and honoring feature flags.

• Documentation

  • Added guidance on adding chain native assets to the popular assets list, including recommended feature-flag patterns and rationale for surfacing native assets beyond CoinGecko listings.

📝 Walkthrough

Walkthrough

Adds native asset IDs for HyperEVM, Monad, Plasma, Sui, and Tron to the popular-assets discovery path (feature-flag gated) and documents the integration pattern for second-class chains in SKILL.md.

Changes

Cohort / File(s)	Summary
Documentation \.claude/skills/chain-integration/SKILL.md	Adds Step 5.5: guidance and a TypeScript example showing how to add native asset IDs (hyperEvm, monad, plasma, sui, tron, etc.) to the Popular Assets list and explains CoinGecko top-100 limitations for second-class chains.
Implementation src/components/TradeAssetSearch/hooks/useGetPopularAssetsQuery.tsx	Expands @shapeshiftoss/caip imports to include hyperEvmAssetId, monadAssetId, plasmaAssetId, suiAssetId, tronAssetId; conditionally pushes these asset IDs into assetIds when corresponding feature flags are enabled, following existing thorchain/mayachain patterns.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

• Verify the listed asset IDs are exported from @shapeshiftoss/caip.
• Confirm feature-flag names match the actual flags and are documented.
• Check for duplicate insertion (file shows identical block twice in doc) and remove if unintended.

Poem

"🐰 I hopped through code to add five more,
Native coins knocking at discovery's door.
Flags set to true, they join the parade,
Little chains cheer — now not so delayed! ✨"
