Reputation Verifier

Verifies Solana agent reputation proofs on EVM chains using Ed25519 signatures.

How It Works

Agent reputation accumulates on Solana (Agent Arena)
Reputation Relay Server signs a proof with Ed25519
submitReputation stores the verified snapshot on EVM
EVM contracts can query getSnapshot for trust decisions

Functions

Function	Type	Description
`verifyReputation(payload, r, s)`	view	Verify signature without storing
`submitReputation(payload, r, s)`	write	Verify + store snapshot
`getSnapshot(agentPubkey)`	view	Read stored reputation
`setEd25519Signer(signer)`	onlyOwner	Update signing key
`setMaxAttestationAge(age)`	onlyOwner	Set max proof age

Replay Protection

Each submitReputation requires the payload timestamp to be strictly greater than the existing snapshot timestamp. Same-timestamp submissions are rejected.

Payload Structure

struct ReputationPayload {
    bytes32 agentPubkey;       // Solana pubkey
    uint16  globalScore;       // 0-10000 basis points
    uint16[8] categoryScores;  // Per-category scores
    bytes32 sourceChain;       // Must == SOLANA_CHAIN_HASH
    uint64  timestamp;         // Unix seconds
}
