Deployed Contracts

All five active chains run the same AKKA Router build. The router is the to address of every transaction returned by the partner quote endpoint and the allowanceTarget for ERC-20 approvals.
The router address is the same on Ethereum, Robinhood Chain and XDC Network (deterministic deployment); Arbitrum and HyperEVM use chain-specific addresses. Base will be listed here when it launches.

​
What is the AKKA Router?

The AKKA Router is the smart contract that executes token swaps on your behalf. The partner quote endpoint returns a transaction targeting the active router for the requested chain. Discover and verify router addresses with GET /partner/v1/chains instead of hardcoding this page. Before swapping ERC-20 tokens, approve the partner quote’s allowanceTarget when it reports INSUFFICIENT_ALLOWANCE. Prefer an exact sellAmount approval, wait for confirmation, and request a fresh quote afterward.
Native tokens (e.g. HYPE on HyperEVM, ETH on Robinhood Chain) do not require approval. Only ERC-20 tokens need to be approved before swapping.
