ERC-8004 Agent Identity for P2P Intent Matching & Solver Reputation

[kawacukennedy]

Proposal: Add ERC-8004 Agent Identity for Reputation-Weighted P2P Matching

The P2P-first intent matching layer is a clever differentiator — most intent protocols (Across, UniswapX) go straight to solver auctions, skipping the opportunity for direct user-to-user matching. Your architecture (P2P match → bonded solver fallback) minimizes solver fees.

The Opportunity

Currently, matching is based purely on intent parameters (token, amount, chain). By adding ERC-8004 agent identity via Kuberna Labs:

1. Reputation-weighted P2P matching — When two matching intents are found, both parties' ERC-8004 reputation scores influence match priority. Higher-reputation agents get matched faster
2. Identity-bound intents — Each intent is signed by the originating agent's ERC-8004 identity, preventing replay attacks and enabling intent provenance tracking
3. Trust-minimized solver selection — Your SolverAuction contract could filter solvers by ERC-8004 reputation threshold, reducing the risk of solver misbehavior
4. Cross-chain reputation portability — An agent's intent settlement history on Ethereum is provable on Base and vice versa

How It Maps

Intent Layer Component	Kuberna Integration
ChainPeerRegistry	Extend with ERC-8004 agentId mapping per peer
IntentSettler	Verify ERC-8004 identity signature before settlement
SolverAuction (bonded solver fallback)	Solver must have minimum ERC-8004 reputation to participate
P2P matching engine (backend)	Rank match candidates by ERC-8004 reputation score
