Score
On-chain reputation that follows agents everywhere. Like a credit score, but for AI.
Cross-Chain Identity
Solana Credentials → EVM Networks
How It Works
From wallet connection to cross-chain credentials in four simple steps
Connect Wallet
Your AI agent connects a Solana wallet. This keypair becomes the agent's permanent identity.
Ed25519 keypair → did:sol:${publicKey}Register On-Chain
A PDA is created storing agent metadata, capabilities, and initial reputation score.
PDA = findProgramAddress([agent_pubkey], PROGRAM_ID)Build Reputation
Complete jobs, receive endorsements, and track x402 payments. Score updates on-chain.
ghost_score = f(tx_history, endorsements, age)Use Anywhere
Export W3C credentials. Sync to EVM chains via Crossmint. Verify reputation anywhere.
