Our platform addresses the trust, transparency, and efficiency gaps in traditional carbon markets — enabling secure, private, and verifiable climate action at scale. The Climate Crisis Demands Bold Infrastructure Global CO₂ emissions hit 36.8 billion tonnes in 2023 (IEA, 2024) IPCC: We have * MAINNET DEPLOYED — No testnet. No simulations. This is live infrastructure*. Verifier Contract: 0xA31a0b24369bb899D557Cb8cc0411b3336778f3f CarbonCredit ERC20 Token: 0x04f083E9925Ad711045Aa896f8022FED9C402a93 Marketplace Contract: 0xAb0992eaD847B28904c8014E770E0294Cd198866 ZKPs: Privacy Without Compromise We utilize SNARKJS + Circom circuits to integrate on-chain zero-knowledge proofs that protect organizational data without sacrificing transparency or verifiability. Why ZKPs Matter: Hide emissions data while proving compliance Maintain financial & operational privacy Prevent reputational risks Ensure trustless verification of: Credit eligibility Credit repayments Borrowing history Emissions reduction > Our ZK circuits are stored on-chain — enabling permissionless, decentralized verification with zero data leakage. ERC20 Tokenization: Liquidity & Interoperability Carbon credits are issued as ERC20 tokens, making them: Fungible Composable with DeFi Easily tradeable on DEXs Auditable on-chain User Profiles & Reputation Scoring Each organization on the platform maintains an evolving, ZK-protected profile: string profilePhotoipfsHashCode; address walletAddress; uint256 timesBorrowed; uint256 timesLent; uint256 totalCarbonCreditsLent; uint256 totalCarbonCreditsBorrowed; uint256 totalCarbonCreditsReturned; uint256 emissions; uint256 reputationScore; This structure powers a reputation-based credit mechanism, where ZKPs are used to validate behavior without revealing raw data — enabling trustless loans, reputation staking, and compliance scoring. 💱 Integrated DeFi Layer for Carbon Finance Borrowing: Use future emissions reductions as collateral Lending Pools: Entities with surplus credits earn yield Tokenized Projects: Invest in fractional climate impact Reputation-Backed Loans: No overcollateralization needed ZK-Enforced Repayments: Privacy-respecting loan cycles Why This Matters | Challenge | Our Solution | | --------------- | ------------------------------------- | | Verification | ZKPs + Mainnet smart contracts | | Privacy | On-chain SNARKs, no data leakage | | Trust | Decentralized, trustless architecture | | Financial Tools | ERC20 credits + DeFi mechanisms | | Deployment | 🚀 Live on Mainnet | 📊 Market Opportunity \$50B voluntary market by 2030 (TSVCM, 2023) \$250B+ compliance market forecasted 91% of firms plan to increase carbon credit spending (S\&P, 2023) Corporate climate spending to exceed \$1T by 2030 🛠️ Smart Contract Interaction & Testing Sample command to verify ZK-protected carbon claim: Submit proof + credit claim carbonMarketplace.submitCarbonClaim( proof, publicSignals, tokenAmount, ipfsHash ); Run unit tests in /contracts/ directory: forge test Contact For partnerships, documentation access, or deployment guidance: [email protected] We are live.
