ApprovalTool

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.

URL: https://bokkypoobah.github.io/ApprovalTool/

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

Design

This dapp is designed to have minimal external dependencies - all code is statically served from GitHub
No backend servers are necessary, only a web3 connection
This dapp uses basic web3 calls for compatibility across EVM chains using the same ERC-20, ERC-721 and ERC-1155 standards

Warning

This is experimental unaudited software. Please check your transaction data carefully when updating your approvals!
