Welcome

A lightweigh web3 dapp tool to manage your approvals for ERC-20, ERC-721 and ERC-1155 token contracts on Ethereum-Virtual-Machine compatible chains.

How This Works

This tool scans for ERC-20, ERC-721 and ERC-1155 Approval and ApprovalForAll log events from the owner's account. This is done using the getLogs(filter) web3 call
These event logs are then processed to determine the approval states for the various ERC-20, ERC-721 and ERC-1155 contracts
The latest ERC-20 approval amounts are retrieved using the ERC-20 allowance(...) function

Requirements

This dapp runs in web3 enabled desktop browsers connected to the Ethereum mainnet, and should work with other Ethereum-Virtual-Machine compatible chains
