Robinhood Chain's dollar is USDG (Global Dollar, Paxos, 6 decimals, 0x5fc5360D0400a0Fd4f2af552ADD042D716F1d168), and the launch form already prices Robinhood tokens in it. The bridge now offers it as a send and receive asset on Robinhood Chain next to ETH. - types: per-chain asset table; USDG added for 4663; asset names, bridgeTokenAsset() for the chain's one ERC-20, isDollarAsset() - validation: symbols come from the chain table; dollar-to-dollar routes (USDC <-> USDG) must quote within 95%..105% of the amount sent, on top of the existing fee and impact limits - approval, client, useBridge, BridgeDialog: token-generic wording, dollar asset is kept when switching chains (USDC <-> USDG) - tests: USDG routes both ways, token substitution refused, dollar bound enforced; live suite sizes amounts by decimals (16/16 routes) - docs/bridge.md: USDG section

0x5fc5360D0400a0Fd4f2af552ADD042D716F1d168, checked on-chain). The launch form already prices Robinhood tokens in it, but the bridge could only move ETH there. Now USDG is a send and receive asset on Robinhood Chain:How
types.ts: one asset table per chain; USDG added for 4663. NewbridgeTokenAsset()(the chain's one ERC-20) andisDollarAsset().validation.ts: no rule loosened. Symbols now come from the chain table. A new bound for dollar-to-dollar routes (USDC <-> USDG): the quoted minimum and the expected output must sit within 95%..105% of the amount sent, on top of the existing fee and impact limits.approval.ts,client.ts,useBridge.ts,BridgeDialog.tsx: token-generic wording ("exact token approval").
