Onboard as a resolver — now self-service

Becoming a 1inch resolver no longer needs a manual, back-and-forth process. You can now onboard yourself in the 1inch Business portal — register contracts for Intent (Fusion), Cross-chain (Fusion+), and limit orders across supported chains, complete verification, and mint Access NFTs when you're approved.

What is a resolver?

Resolvers fill orders in the 1inch protocol — executing Intent (Fusion), Cross-chain (Fusion+), and limit orders. To participate, a resolver registers the on-chain contract addresses it uses on each chain so the protocol can recognize it.

How self-service onboarding works

1. Set business activity — select Resolver as a business segment. New accounts do this during registration; existing customers add it under Company profile, then continue in Resolver profile.
2. Entity type and terms — choose your entity type and accept the Business Portal Terms of Use and the Resolver Terms of Use.
3. Resolver information — add your resolver name (required) and optional SVG logo URL, then register contract addresses per protocol (Limit Order, Intent, Cross-chain) on every chain you operate on. Addresses are scanned across chains; the UI flags blacklisted contracts.
4. KYC / KYB — complete verification for your entity. If KYB gets stuck, contact compliance@1inch.com.
5. Compliance survey — finish the resolver compliance survey. Whitelisting stays blocked until both verification and the survey are done.
6. Access NFT minting — after KYC/KYB approval and the survey, Access NFT(s) are minted for your contracts, granting access to order fulfillment. You'll get a confirmation email when minting completes.

Before you start

• Have your resolver contract addresses ready for each chain and protocol you plan to support.
• Use a wallet that controls those contracts — you'll need it for Access NFT minting.
• Make sure you have enough gas on each chain for the mint transactions.
