Add BNB Chain support to bridge and balance breakdown#2117
Merged
Conversation
Add Binance-Peg USD Coin (USDC, 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d)
on BNB Chain as a new bridge deposit source in the Add Funds ("send from
your crypto wallet" + "share your deposit address") and Deposit-to-Savings
(USDC vault) flows, alongside Polygon/Arbitrum.
- constants/bridge.ts: BSC entry (USDC, 18 decimals, isPermit false) + gold
circular BNB icon; add optional decimals to BridgeToken type
- lib/thirdweb.ts: register bsc chain so switchChain works in the
connected-wallet deposit flow
- hooks/useDepositFromEOA.ts: derive source-token decimals from the bridge
config instead of hardcoding 6 (BSC USDC is 18 decimals)
- constants/alchemy.ts: enable BSC token-balance fetching via Alchemy
- components/Coin/BalanceBreakdown.tsx: map the BSC chain icon + name in the
coin detail network breakdown
- assets/images/bsc.png + lib/assets.ts: circular gold BNB Chain icon
