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/

• 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

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