Discount Bond Vesting Claimer

WHAT IT DOES

Discount Bond Vesting Claimer is a non-custodial tool that claims vested portions of discount bonds according to vesting schedules, enabling users to receive their allocated tokens as they vest over time. It reads discount bond vesting contract state, user address, token balances, vesting parameters, bond ID, vesting schedule, claimable amount, total vested, vesting start, vesting cliff, claim eligibility, claim deadline, claim status, user's purchase history, and settlement state to structure the optimal vesting claim operation. With a single transaction, it calls claimVestedBond(), executeVestingClaim(), or submitVestingClaim() on the target contract, claiming the currently vested portion of discount bonds. The tool handles various vesting schedules including linear, cliff, and milestone-based vesting.

HOW TO USE

1. Connect your wallet (EVM-compatible).

2. Paste the discount bond contract address.

3. Enter the bond ID and optionally specify a token address.

4. Review the claimable amount, total vested, vesting schedule, claim eligibility, and claim deadline.

5. Click "claim vested bonds" and confirm the transaction in your wallet.

The tool checks claim eligibility and claim status before execution to prevent failed transactions. After the transaction confirms, your vested tokens are claimed on-chain—no centralized custody, no intermediaries. Your vested tokens are transferred to your wallet.

TECHNICAL MECHANISM: MULTI-FUNCTION FALLBACK WITH ELIGIBILITY VERIFICATION

Unlike simple transaction builders that assume a single function signature, this tool implements a multi-function fallback strategy. It first attempts claimVestedBond(), then falls back to executeVestingClaim() or submitVestingClaim() if the primary method fails—automatically adapting to different contract implementations without requiring the user to know the exact function name. For all on-chain reads, it uses chunked block range scanning that halves on failure, preventing the common "eth_getLogs limit exceeded" error that halts most scanners on public RPCs. It double-verifies claim eligibility by checking both the current vesting status and claim deadline from storage, rather than relying on historical events—because an event log proves a bond was purchased, not that the current vesting claim can be accepted. Gas estimation uses receipt.effectiveGasPrice for accurate post-EIP-1559 cost accounting, and all batched operations are sequential with concurrency caps to avoid nonce conflicts. The tool also validates that the vesting schedule has been met and that the claim deadline has not passed before execution.

WHAT IT CANNOT SEE

This tool cannot verify that the discount bond contract is legitimate or has not been compromised. It cannot detect if the bond has been manipulated. It cannot ensure that claim will execute at the optimal gas price due to network conditions. It cannot guarantee that claim will succeed if the contract is paused or frozen. It cannot verify that the contract has not been upgraded or modified. It cannot detect if the trade path is optimal or not front-run. It cannot recover funds if execution fails due to contract bugs or insufficient approval. It cannot verify that the claimable amount is correct or not. It cannot predict market movements, price gaps, or flash crashes. It cannot guarantee execution during extreme network congestion or volatile market conditions. It cannot detect if the underlying issuer has been compromised. It cannot prevent the user from canceling or modifying claim parameters. It cannot ensure that the claim will be processed. It cannot protect against loss if claim is rejected. It cannot verify that the vesting schedule has been met. It cannot guarantee that the full amount will vest. It cannot ensure that the claim deadline has not passed.

PLEASE NOTE

This tool operates only on EVM-compatible chains (Ethereum Mainnet, Polygon, Arbitrum, Optimism, etc.). It is non-custodial—you retain full control of your funds at all times. Always verify contract addresses, bond IDs, and claim parameters before executing. Vesting claims are subject to claim deadlines—claims must be made within the claim window. The tool is provided as-is; use at your own risk.
