Introduction

Welcome to the onboarding guide for becoming a Resolver in the 1inch ecosystem. This document outlines the self-service onboarding process and helpful resources for resolving Intent-based Orders (Fusion and Cross-chain/Fusion+ Orders) and Limit Orders .

Self-Service Onboarding

Step 1: Login/Register

Visit the 1inch Business Portal login page and select the preferred registration method.

On the first onboarding screen, select your business segment(s) from the available options (multi-select): Resolver and other applicable segments.

Step 2: Set your entity type and accept the terms

Select your entity type and confirm that you've read, understood, and accepted the Terms of Use of the Business Portal and the 1inch Network Terms of Use for Resolvers

Step 3: Provide Resolver Information

  1. Provide the following resolver details:
  • Resolver name (required)

  • Logo (optional) — URL to your logo in SVG format. The URL must point to a valid image file.

  • Contract Address for each protocol where resolving is intended

Protocol Configuration
Limit Order (LO) Chains + contract addresses
Intent Chains + contract addresses
Cross Chain Chains + contract addresses

Contract address validation:

  • Every contract address you add is automatically scanned across all chains before you proceed.
  • The UI indicates if a contract address is blacklisted (flagged as positive).

Step 4: Perform KYC/KYB

Complete the verification process based on your selection in Step 2.

If you face any difficulties with KYB, please reach out to compliance@1inch.com.

Step 5: Complete Compliance Survey

Complete the compliance survey for resolvers. This step is mandatory and no whitelisting will be enabled until the verification and survey have been completed.

Step 6: NFT Minting and Confirmation

Once both of the following are complete:

  • KYC/KYB approval
  • Compliance survey completion

Your Access NFT(s) will be minted, granting access to Order fulfillment.

Email notifications:

  • A single confirmation email is sent after all NFTs are minted.
  • If any contract address becomes blacklisted during this step, you will receive a notification email (content to be provided).

Protocol-Specific Onboarding

From here, the next steps are determined by the protocol you choose to integrate with. Please follow the corresponding subsection.

Intent-Based Orders

Request Off-Chain Auction Access [optional for Fusion Orders]

Resolvers may apply for off-chain auction access to Fusion Orders before the Dutch Auction phase begins. To request access:

  1. Provide your API endpoint developed in accordance with the Exclusive Resolver API script example and related technical documentation.
  2. Submit the request via the dedicated support communication channel created during onboarding.
  3. Upon review and approval by the technical team, your Resolver will be integrated into the Exclusive Resolver API and granted off-chain auction access to Fusion Orders before the Dutch Auction phase begins.

Participation in the Exclusive Resolver API requires ongoing compliance with the Service Level Agreement (SLA) as detailed in Annex A of the Resolver Terms of Use. Exclusive Resolver API Documentation

Intent

Cross-chain

Governance-Dependent Functionality The whitelisting, farming, and any Unicorn Power-based exclusivity or eligibility mechanisms are currently disabled for Fusion Orders as per 1IP-89 and shall apply only if and when enabled through a governance vote or a decision originating therefrom.

Until such activation occurs, these features remain unavailable, and Intent Order Resolvers are not required to perform any related actions.

Limit Orders

Choose Your Strategy

Option 1: Unicorn Power (UP) Enabled

Stake and delegate 1INCH tokens to accumulate Unicorn Power (UP). To qualify for the whitelist and become eligible to execute Limit Orders, your resolver must hold at least 5% of the total UP across all whitelisted resolvers. Complete the steps from the Unicorn Power setup:

Fees 50% fee discount on Limit Orders. ❗ Requires at least 5% UP:

  • 1 bps for stable/pegged pairs
  • 25 bps for non-stable pairs

Option 2: No Unicorn Power (UP)

  • Limit Orders (standard fee applies). 🔷 Farming and 5% UP are not required.

Fees

  • 2 bps for stable/pegged pairs
  • 50 bps for non-stable pairs

No further steps required.
