Chains

Robinhood Chain is the default. Base, BNB Chain, Ethereum, Arbitrum One and OP Mainnet use the same API with the chain name in front of the path. Your partner key works on every chain listed here, with the same Route fee, rate limit and build permission it has on Robinhood Chain (limits are counted per chain).

Each chain serves /quote, /tokens and /health with the same parameters and response as on Robinhood Chain. Use the zero address for the chain’s native token (ETH, or BNB on BNB Chain). On these chains /tokens returns the token’s pool count without name or symbol metadata.

Building transactions

With recipient, the transaction goes to that chain’s executor from the table, which is also the token spender: approve that address on that chain, not a Robinhood Chain contract. The executor runs the route, checks your minimum output and pays the Route fee from the output. Every executor is verified on Sourcify. Route contracts have not been independently audited; users should review every transaction before signing.

Robinhood Chain only

Vault zaps, partner fees, gasless swaps, standing orders, delegated execution, owned landing (/submit) and JIT routing are available on Robinhood Chain only.
