A signed, portable proof artifact for wallet-controlled DeFi evidence.
DeFi Passport lets a wallet holder create a signed public proof card from public-chain activity. The holder signs a harmless EIP-191 message to request issuance; Gregers signs the resulting snapshot as a Concordium ecosystem participant.
A Gregers-built Concordium ecosystem experiment showing how wallet-controlled DeFi evidence can become a signed, portable proof artifact. V2 requires a wallet signature before issuance. It is deliberately not “ZK-style”; it uses public on-chain data plus wallet and Gregers signatures.
This is public-chain data. It is not financial advice, not a credit score, not an official Concordium communication, and not a recommendation to trade. The wallet signature proves control of the address for this passport request; it does not authorize any transaction, transfer, allowance, or trade.

Third-party GET lookups do not trigger fresh wallet scanning. Issuance requires this wallet-signed challenge plus consent.
Create a message, sign it in your wallet, paste the signature, then issue.
