Base ERC-4626 Vault Share Batch Redemption Tool

WHAT IT DOES

Base ERC-4626 Vault Share Batch Redemption Tool lets you redeem multiple batches of vault shares for their underlying assets in a single sequence of transactions on the Base network. The tool reads your connected wallet and chain ID, identifies the vault's asset token, and verifies your share balance. You provide the ERC-4626 vault address and a list of share amounts to redeem. The tool checks your share balance and maximum redeemable amount, approves the vault to spend your shares, then executes redemptions sequentially. Each redemption converts vault shares back to the underlying asset, with all redemptions sent to your wallet. This is ideal for unwinding positions, processing withdrawals, or managing vault exposures efficiently.

HOW TO USE

Connect your wallet and ensure you are on the Base network. Enter the ERC-4626 vault address. Paste your redemption list as comma-separated values (one per line: owner, share amount). Note that the owner must be your connected wallet address—this tool only supports redemptions for shares you own. Review the summary table showing total shares to redeem and the underlying asset. Click "sign & redeem batch" to approve the vault and execute the redemptions. The tool will process each redemption sequentially, converting shares to the underlying asset.

TECHNICAL MECHANISM

The tool does not use any hardcoded contract addresses—you provide the vault address, ensuring you are in full control of where your redemptions go. It reads the vault's asset address and symbol using the ERC-4626 asset() method. It verifies your share balance and checks maxRedeem() to ensure you can redeem the requested amounts. It then approves the vault to spend your shares using approve() and calls redeem() for each redemption, passing the share amount, receiver address (your wallet), and owner address (your wallet). Each redemption is processed sequentially to avoid nonce conflicts and ensure atomic success—if any redemption fails, the transaction reverts and no redemptions are finalized. The tool treats ERC-4626 vault shares as standard ERC-20 tokens and uses the vault's own redemption logic.

WHAT IT CANNOT SEE

This tool cannot send native ETH or any token other than ERC-4626 vault shares. It does not detect token tax, fee-on-transfer, rebasing, or deflationary mechanics—it assumes standard ERC-4626 vaults with standard ERC-20 behavior. It cannot recover incorrectly entered share amounts or owner addresses. It is limited to ERC-4626 vault share tokens on Base network only. It does not simulate or estimate gas costs beyond the transaction fees. Each execution is a separate transaction sequence—there is no recurring or scheduled redemption. Most importantly, this tool does not verify the vault's underlying yield accrual, asset composition, or withdrawal mechanics—it simply calls the vault's redeem() function. It does not handle vaults with time-weighted or performance fees that affect share value. It does not support redemption of shares from multiple users in a single transaction unless the sender holds all the shares being redeemed.

PLEASE NOTE

This tool only works on the Base network (EVM-compatible). It requires a web3 wallet (e.g., MetaMask) connected via the injected wallet bridge. Always double-check your share amounts before signing. The tool is free to use; only blockchain transaction fees apply. Ensure you are using the correct ERC-4626 vault address—using the wrong contract could result in loss of funds. Redemption may be subject to vault-specific fees, withdrawal limits, or delays.
