Contract Addresses

All HyperQuote contracts are deployed on HyperEVM mainnet (chain ID 999). This page lists the official verified addresses. Testnet deployments are not currently available.

Verify you are using official HyperQuote resources. Only interact with the contract addresses listed on this page. Cross-reference against the Official Links page and the HyperQuote app before approving any token transfers.

Who This Is For

Developers integrating with HyperQuote contracts directly.
Makers configuring their SDK or bot to point at the correct settlement contract.
Security researchers reviewing on-chain code and verifying deployments.
Anyone who needs to verify a contract address before approving token transfers.

HyperEVM Mainnet

Contract	Address	Description
SpotRFQ	TBD	Atomic spot token swap settlement — verifies EIP-712 signatures, enforces nonces, executes bilateral token transfers

Always verify contract addresses against this page or the HyperQuote app before interacting with them. Do not trust addresses from unofficial sources.

Once deployed, contract source code can be verified on the block explorer at hyperscan.xyz :

EIP-712 Domain Parameters

When constructing EIP-712 signatures for the SpotRFQ contract, use these domain parameters:


const domain = {
  name: "HyperQuote",
  version: "1",
  chainId: 999,
  verifyingContract: SPOT_RFQ_CONTRACT_ADDRESS,
};

The verifyingContract field must match the deployed SpotRFQ address listed above. Signatures constructed with a mismatched domain will be rejected by the contract.

Local Development

For local development with Foundry, the default contract address used by the HyperQuote build system is:


0x5FbDB2315678afecb367f032d93F642f64180aa3

This is the standard first-deployed address on a fresh Anvil instance. Set it via the NEXT_PUBLIC_RFQ_CONTRACT_ADDRESS environment variable.

Edge Cases

Scenario	What happens
Using the wrong `verifyingContract` in EIP-712	The contract rejects the signature. The fill transaction reverts.
Interacting with an unverified contract address	Potential loss of funds. Always cross-reference addresses with this page.
Approving tokens to the wrong contract	Tokens could be stolen by a malicious contract. Only approve the official SpotRFQ address.
Contract address changes after redeployment	The old contract remains immutable. Check this page for the current canonical address.
