● Second, this raw data is uploaded, and the NGO's own Admin reviews it on the web dashboard. This internal check is a key part of our data integrity model.

● Third, once satisfied, the NGO Admin signs a transaction with their MetaMask wallet. This is the crucial action that records the data package permanently onto the Polygon smart contract.

● And finally, an authorized NCCR Verifier reviews this immutable on-chain record. When they sign the final approval, the smart contract automatically mints the corresponding carbon credit tokens directly to the NGO's wallet.

This entire process, from field to finance, is transparent, secure, and auditable by anyone.

● For our Web & Mobile frontend, we're using React and React Native for a modern, unified user experience.

● Our Off-Chain Services are built on the reliable Node.js and Express.js stack.

● For our database and storage, we use a hybrid model of MongoDB and IPFS.

● And finally, the core of our system is the Blockchain layer. We use Solidity for our smart contracts, professional tools like Hardhat, and deploy on the Polygon Amoy Testnet for its proven scalability and low cost.
