Renewable Energy Certificate Tokenizer

WHAT IT DOES

This tool provides on-chain tokenization of renewable energy certificates (RECs), enabling you to represent renewable energy generation as transferable tokens. It reads your connected wallet address, tokenization contract address, REC project ID, energy source (solar, wind, hydro), certificate amount in MWh, issuance timestamp, current block timestamp, token status, owner address, and tokenization history. You can then sign and send transactions to tokenize renewable energy certificates with full energy metadata, transfer tokens to other addresses, retire tokens to offset energy usage, and record tokenization metadata on-chain. All token parameters are displayed in a clear review panel before you sign, so you know exactly what you are tokenizing. The tool also logs transaction hashes, confirmation status, and gas costs, providing a complete audit trail of all tokenization activities.

HOW TO USE

Connect your wallet using the built-in wallet bridge, choose the network that matches your tokenization contract, and paste the tokenization contract address. Enter the REC project ID, select the energy source (solar, wind, hydro, geothermal, or biomass), enter the certificate amount in MWh as raw units, and token decimals for display purposes. The review panel shows all inputs, the current token status, and tokenization history before you sign. Use the numbered action buttons: check token to view current token status, amount, owner, and issuance timestamp; tokenize REC to create a new token representing a renewable energy certificate; transfer token to send a token to another address; or retire token to retire the certificate and offset energy usage. You can also view tokenization history to see all token IDs associated with an owner address. Each transaction is signed sequentially, and the tool displays transaction details and confirmation status.

THE REAL MECHANISM

This tool uses ethers.js v5.7.2 to build and send transactions through the wallet's signer. It does not rely on any hardcoded contract addresses – you paste the tokenization contract you are using, so you are in full control. When you tokenize a REC, the tool constructs a contract call to the tokenizeREC function, which takes the project ID, energy source string, and certificate amount. The contract mints a new token with a unique ID, stores the energy source and amount metadata on-chain, sets the issuance timestamp, and transfers the token to your address. When you transfer a token, the tool calls transferToken, which sends the token to the specified recipient. When you retire a token, the tool calls retireToken, which marks the token as retired and records the retirement timestamp. The tool reads token state via getToken, which returns the project ID, energy source, amount, owner, issuance timestamp, and retired status, as well as getTokenizationHistory for the full history. All transactions are sequential to prevent nonce conflicts, and gas costs are calculated using effectiveGasPrice for accurate post-EIP-1559 reporting.

WHAT IT CANNOT SEE

This tool cannot verify off-chain renewable energy generation, validate REC authenticity, detect double-counting, or ensure that the tokenization contract handles tokenization correctly. It cannot detect if the renewable energy was actually generated or if the REC is authentic. The tool also cannot verify that the tokenization contract correctly handles edge cases like duplicate project IDs, invalid energy sources, or retirement logic. It cannot simulate the outcome of a transaction before you sign it, nor can it guarantee that the token will be minted correctly if the contract is not properly implemented.

PLEASE NOTE

This tool works only on EVM-compatible chains supported by your wallet and provider. Always double-check the contract addresses and project parameters before signing. Use testnet first. The tool is a transaction-signing interface and tokenization management tool, not a renewable energy generation or REC authenticity validation system.
