Summary

This proposal seeks to remove the 5% Unicorn Power (UP) staking threshold currently required for resolvers to obtain access to Fusion exclusive orders. Under the proposed update, any resolver will gain full access to Fusion’s exclusive order flow upon successful completion of the due diligence verification process and issuance of the corresponding Resolver NFT for verification.

Motivation

The 5% UP threshold was initially introduced as a mechanism to ensure that active, aligned participants contributed to protocol security and long-term engagement. However, as the Fusion ecosystem evolved, this requirement has become a barrier to entry for new resolvers and a limiting factor for competition and liquidity access.

Removing the UP threshold will streamline onboarding, foster broader adoption of Fusion and widen the liquidity accessed through Fusion protocol. Due diligence verification and Resolver NFT issuance will remain the key mechanism ensuring resolver accountability and risk management.

Specification

• The requirement for resolvers to hold or stake 5% of Unicorn Power to access Fusion exclusive orders will be removed.

• Access to Fusion exclusive order flow will be granted upon issuance of the Resolver NFT, which will be minted following successful completion by the resolver of the due diligence verification.

• 1inch Foundation remains responsible for facilitating resolver onboarding. Under this proposal, 1inch Foundation requests 1inch Business to host and administer the onboarding and verification process, including automatic Resolver NFT generation.

• Recognizing the importance of community mechanisms, Resolver farms remain part of the framework. While not a prerequisite for participation, they continue to exist as an optional layer that can be activated to support incentivization, enhance competition and improve overall performance when needed.

• This proposal continues the framework established under 1IP-78, requires to follow a tiered fee structure. It reaffirms that Resolver Access Fees can be enabled as part of the protocol design. This structure applies to resolvers acting as infrastructure integrators. The allocation of collected Resolver Access Fees (e.g. to the DAO treasury or other recipients) will be determined by the DAO through future governance decisions.

Rationale

This adjustment simplifies the resolver onboarding process while maintaining the same compliance and verification standards. By removing the UP threshold, the protocol can:

• Increase competition among resolvers;

• Improve liquidity depth and execution quality;

• Support broader adoption of Fusion as an open, competitive settlement layer.

The due diligence and NFT framework ensures that access remains restricted to verified and accountable counterparts, preserving the integrity and security of the Fusion ecosystem.

Implementation

• The existing resolver onboarding flow will be updated so that due diligence verification — not UP staking — serves as a trigger for Resolver NFT issuance, which defines access eligibility.

• 1inch Foundation requests 1inch Business, which is the 1inch Web3 APIs portal, to implement and technically enable the updated onboarding and Resolver NFT-issuance process within the existing resolver infrastructure.

• Security and deployment: the 1inch Fusion mode has already been audited and fully deployed. This proposal does not modify smart-contract logic or auction mechanics; it only broadens resolver participation by adjusting access conditions. As such, no negative security implications are anticipated.
