Tokenbound Account Contracts

This repository contains an opinionated ERC-6551 account implementation. The smart contracts are written in Solidity using the Foundry development framework.

This project is under active development and may undergo changes until ERC-6551 is finalized. For the most recently deployed version of these contracts, see the v0.3.1 release. We recommend this version for any production usage.

Contracts

The src/ directory contains the main contracts for the project:

• Account.sol: This contract is the main ERC-6551 account implementation. It includes functionalities for executing a low-level call against an account if the caller is authorized to make calls, setting the implementation address for a given function call, granting a given caller execution permissions, locking the account until a certain timestamp, and more.

• AccountGuardian.sol: This contract manages upgrade and cross-chain execution settings for accounts. It includes functionalities for setting trusted implementations and executors.

• AccountProxy.sol: This contract is an ERC-1967 proxy which enables account upgradability. It includes functionalities for initializing and getting the implementation of the contract.
