Robinhood Chain
The selected network, what is connected today, and what on-chain settlement must actually mean.

Network details#
| Property | Mainnet | Testnet |
|---|---|---|
| Chain ID | 4663 | 46630 |
| Gas asset | ETH | Test ETH |
| Public RPC | https://rpc.mainnet.chain.robinhood.com | https://rpc.testnet.chain.robinhood.com |
These values were checked against Robinhood's official documentation during the reference review. Public RPC endpoints are rate-limited and are not a production infrastructure plan by themselves. Operators should select appropriate RPC service, monitoring, and recovery behavior before money depends on it.
What is connected today#
The wallet sign-in flow is bound to Robinhood Chain. The browser requests the correct network and the server constructs and verifies a chain-bound sign-in message. That is authentication—not an on-chain account registration, deposit, escrow, or payout.
The application and PostgreSQL database run off-chain. Model execution will also run off-chain. Blockchain integration should provide verifiable payment/settlement activity where appropriate; it does not make the whole application decentralized or trustless.
Settlement asset selection#
USDG appears in Robinhood's official token-contract registry and is the proposed settlement asset for this product direction. Before integration, verify the exact chain, contract, decimals, issuer/bridge properties, and supported authorization mechanism. A matching token symbol is not sufficient.
What must precede settlement#
- An approved custody, refund, withdrawal, and supplier-payout model.
- Verified treasury controls and restricted signing authority separate from the web application.
- Documented confirmation/finality handling, duplicate-event protection, reorg recovery, and reconciliation.
- Tests for wrong-chain, wrong-token, incorrect-amount, delayed, and duplicate payments.
- A capped testnet-to-mainnet rollout with explicit approval for real funds.
