Yield Vault Performance Fee Claim Tool

WHAT IT DOES

Yield Vault Performance Fee Claim Tool enables fee recipients to claim performance fees accrued from yield vaults. The tool reads your connected wallet address, vault contract address, performance fee amount, fee token address, token decimals, claim status, current block timestamp, fee period start/end times, vault performance metrics, and fee calculation parameters. It checks whether your wallet is the designated fee recipient, displays the accrued fee amount, the fee period, and the vault's performance. If you are eligible and the fee has not been claimed, you can submit the claim transaction to withdraw the performance fee.

HOW TO USE

Connect your wallet and select your network. Enter the yield vault contract address and the fee token address. Click "Check performance fee" to load the current fee details including the accrued fee amount, fee period start and end times, vault performance percentage, whether you are the fee recipient, and whether the fee has already been claimed. If you are the fee recipient and there are unclaimed fees, click "Claim performance fee" to submit the claim transaction. The tool will confirm the claim and update the status. Your wallet must be the registered fee recipient address to claim.

THE REAL MECHANISM — PERFORMANCE FEE ACCRUAL WITH PERIOD-BASED TRACKING

Unlike simple fee withdrawals that only check a balance, this tool implements a period-based performance fee system. The vault calculates performance fees based on the increase in the vault's net asset value (NAV) over a defined period. The getPerformanceFee function returns the accrued fee amount, the period start timestamp, and the period end timestamp. The fee amount is computed as a percentage of the vault's profit during the period. The getPerformance function returns the overall performance percentage for the vault. The fee recipient is set by the vault deployer or governance, and only this address can call claimPerformanceFee. The isFeeClaimed function prevents double-claims. The claim function transfers the fee token amount from the vault to the recipient. The tool reads all fee data via getPerformanceFee and validates the recipient address via getFeeRecipient, displaying clear eligibility status. All arithmetic uses ethers.js BigNumber with the token's decimal precision, and gas costs are reported using receipt.effectiveGasPrice.

WHAT IT CANNOT SEE

Cannot verify off-chain performance accuracy—the tool relies on the vault's on-chain performance calculation and cannot audit how performance was measured. It cannot ensure fee calculation correctness—the tool does not verify the fee formula or validate the period-based calculation. It cannot predict future vault performance—the tool cannot forecast how the vault will perform in upcoming periods. It cannot detect if the vault contract contains vulnerabilities or malicious code—the tool does not audit the vault logic. It cannot recover fees if the claim fails or if the fee recipient address is incorrect.

PLEASE NOTE — EVM CHAINS ONLY

This tool exclusively supports EVM-compatible chains where ethers.js can connect via standard JSON-RPC. It does not support non-EVM chains such as Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, or XRP. The vault contract must implement the specific interface expected by this tool (claimPerformanceFee, getPerformanceFee, isFeeClaimed, getFeeRecipient, getPerformance). Always verify that you are the registered fee recipient before claiming. This tool is a fee claim interface, not a financial advisor or investment consultant.
