# 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/](https://bokkypoobah.github.io/ApprovalTool/)

---

### How This Works

* This tool scans for [ERC-20](https://eips.ethereum.org/EIPS/eip-20#events), [ERC-721](https://eips.ethereum.org/EIPS/eip-721#specification) and [ERC-1155](https://eips.ethereum.org/EIPS/eip-1155#specification) *Approval* and *ApprovalForAll* log events from the owner's account. This is done using the [getLogs(filter)](https://docs.ethers.org/v5/api/providers/provider/#Provider-getLogs) 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

---

### Running Locally

* In a folder on your computer, **git clone [https://github.com/bokkypoobah/ApprovalTool](https://github.com/bokkypoobah/ApprovalTool)**
* Run a tool like [anywhere](https://www.npmjs.com/package/anywhere) in the ./docs subdirectory of the folder created above

---

### 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!
