Carbon Credit Trading Registry
Issue, trade and retire credits without counting any twice
4-5 weeks build
Overview
Verifier accounts approve emission-reduction projects and issue credits as ERC-1155 tokens, one token ID per project vintage. Companies trade credits in an order book and retire them to offset emissions; retiring burns the token and writes a certificate, so a credit can never be sold or claimed again. Project documents sit in PostgreSQL with hashes on-chain. Test deployment on Sepolia or Polygon Amoy.
