Protocol Bond Redemption Tool

WHAT IT DOES

Protocol Bond Redemption Tool is a DeFi tool that enables users to redeem their protocol bonds once they have vested. It reads the bond contract address, the user's bond token balance, vesting schedule (cliff and vesting period), current vesting status (vested/unvested amounts), bond redemption eligibility, redemption price, redemption history, account nonce, gas estimates for redemption, and previous redemption records. The tool then guides you through redeeming vested bond tokens, burning the redeemed tokens, transferring the underlying assets to your wallet, updating your vested balance, syncing redemption status across chains if applicable, and claiming any unvested tokens if they are forfeited.

HOW TO USE

Connect your wallet via the built-in connector. Select the network where the bond contract is deployed. Enter the bond contract address and the amount of bond tokens you wish to redeem. The tool will read on-chain data and display a preview including: bond contract, your bond balance, redeem amount, vested amount, unvested amount, cliff duration, vesting period, redemption price, eligibility (eligible or insufficient vested), and estimated gas. Review all details carefully. Click "redeem bonds" to execute the redemption. The tool will guide you through four steps: verifying vesting and eligibility, burning redeemed bond tokens, transferring underlying assets, and updating your vested balance.

TECHNICAL MECHANISM

The tool uses ethers.js v5.7.2 to interact with the bond contract. It reads the user's bond token balance using `balanceOf(user)` on the bond token contract. Vesting schedule is read via `getCliff()` and `getVestingPeriod()` view functions. Current vesting status is calculated using `getVestedAmount(user)` and `getUnvestedAmount(user)`, which take into account the time elapsed since the bond was purchased. Redemption eligibility is checked using `isEligibleForRedemption(user)` which verifies that the requested amount does not exceed the vested balance. Redemption price is read via `getRedemptionPrice()` which returns the exchange rate between bond tokens and underlying assets. Redemption history is scanned using `eth_getLogs` for `BondRedeemed` events, with adaptive chunking (halving chunk size on failure) to handle different RPC limits—the tool walks backward from the current block and continues even if some ranges are rejected. The redemption transaction calls `redeemBonds(amount)` on the contract, which burns the specified bond tokens and transfers the underlying assets to the user. Gas estimates are calculated using `estimateGas` on the redemption method with EIP-1559 fee data from `feeData`. All transactions are built with EIP-1559 fee data, and the tool uses `effectiveGasPrice` from receipts for accurate cost accounting.

WHAT IT CANNOT SEE

This tool cannot predict future price changes affecting redemption value—the redemption price may be different at the time of execution. It cannot guarantee that the protocol will have sufficient liquidity for redemption—the protocol may not hold enough underlying assets. It cannot detect if the vesting schedule is manipulated by the contract owner. It cannot ensure that the redemption price reflects fair market value. It cannot prevent front-running of redemptions by other users. It cannot validate that the protocol will honor redemption terms—this is a trust assumption. It cannot verify that the bond contract is secure or free from vulnerabilities. It cannot predict changes in protocol governance that could affect redemption terms or rates.

PLEASE NOTE

This tool is EVM-only and supports Ethereum, Polygon, BNB Chain, Arbitrum, Optimism, and Avalanche. The redemption transaction is signed by the connected wallet, and the user pays gas fees. Only vested bond tokens are eligible for redemption. The tool does not store or transmit any bond data. Always verify your vesting status and redemption eligibility before executing. Test on testnet before using on mainnet.
