Blue Carbon Registry

A decentralised trading platform for carbon credits from blue carbon ecosystems, running on the Ethereum Sepolia testnet with MetaMask wallet integration. Built in September 2025.

What I built

ERC-20 smart contracts for minting credits and for auditor verification, plus role-based dashboards for NGOs, auditors and companies.

Hardest part

Making minting trustworthy: credits are only minted after an auditor verifies them on-chain, and each role sees only what it is allowed to act on.
