Carbonexis is a blockchain platform for certified climate projects to trade carbon credits and Support NFTs with full transparency, traceability, and on-chain proof.
Carbonexis is a blockchain-based platform designed to revolutionize the carbon credit ecosystem by offering transparency, traceability, and dual marketplaces. It empowers verified environmental projects to issue and trade both carbon credits (ERC20 tokens) and Support NFTs (ERC1155), enabling organizations to raise funds and individuals or companies to offset their carbon footprint effectively.
Two Marketplaces:
Credit Marketplace: Buy/sell carbon credits (ERC20) based on price per ton.
NFT Marketplace: Trade Support NFTs (ERC1155) linked to real environmental initiatives.
Project Certification:
Projects must pass KYC and are issued a soulbound NFT (ERC721) as certification before being allowed on the platform.
Smart Contracts:
Handle NFT minting, carbon credit issuance, project certification, royalty distribution (EIP-2981), and milestone-based fund allocation.
Automated Workflow:
From KYC → Certification NFT → Project Registration → Support NFT/Carbon Credit Listing.
Tech Stack:
Frontend: React + Tailwind
Backend: Node.js + Express
Blockchain: Solidity on Polygon (mainnet) & Sepolia (testnet)
Storage: IPFS for NFT assets
Use Case:
Helps companies meet ESG goals while ensuring every transaction and project is publicly verifiable on-chain.
