Revolving Credit Line Renewal Tool

WHAT IT DOES

This tool provides on-chain renewal of revolving credit lines, enabling you to extend credit lines, update credit terms, and manage outstanding balances. It reads your connected wallet address, credit line contract address, borrower address, credit limit, outstanding balance, renewal fee, current block timestamp, renewal eligibility, and renewal history. You can then sign and send transactions to renew revolving credit lines by paying renewal fees, update credit terms (such as the credit limit), and record renewal metadata on-chain. All credit line parameters are displayed in a clear review panel before you sign, so you know exactly what you are renewing. The tool also logs transaction hashes, confirmation status, and gas costs, providing a complete audit trail of all renewal activities.

HOW TO USE

Connect your wallet using the built-in wallet bridge, choose the network that matches your credit line contract, and paste the credit line contract address. Enter the borrower address, the renewal fee in raw units, the new credit limit in raw units, and token decimals for display purposes. The review panel shows all inputs, the current credit limit, outstanding balance, and renewal eligibility before you sign. Use the numbered action buttons: check status to view current credit line state, limit, outstanding balance, last renewal time, and eligibility; renew line to renew the credit line by paying the renewal fee; or update terms to modify the credit limit without requiring a renewal. You can also check status to view current credit line metrics, or view renewal history to see all past renewal timestamps. 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 credit line contract you are using, so you are in full control. When you renew a credit line, the tool constructs a contract call to the renewCreditLine function, which transfers the renewal fee from your wallet, verifies eligibility, and extends the credit line's validity. When you update terms, the tool calls updateCreditTerms, which updates the credit limit without a full renewal. The tool reads credit line state via getCreditLine, which returns the limit, outstanding balance, last renewal timestamp, and active status, as well as renewalEligible to check if renewal is allowed. 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 borrower creditworthiness, predict default risk, ensure credit line solvency, or verify that the credit line contract handles renewals correctly. It cannot detect if the borrower is creditworthy or if the renewal fee is appropriate. The tool also cannot verify that the credit line contract correctly handles edge cases like expired credit lines, outstanding balances, or term updates. It cannot simulate the outcome of a transaction before you sign it, nor can it guarantee that the renewal will be processed 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 parameters before signing. Use testnet first. The tool is a transaction-signing interface and credit line management tool, not a credit assessment or default prediction system.
