Safe Contracts

npm version Build Status Coverage Status

:warning: This branch contains changes that are under development To use the latest audited version make sure to use the correct commit. The tagged versions that are used by the Safe team can be found in the releases.

Usage

Install requirements with yarn:

yarn

Testing

To run the tests:

yarn build
yarn test

Optionally, if you want to run the ERC-4337 compatibility test, it uses a live bundler and node, so it contains some pre-requisites:

  1. Define the environment variables:
ERC4337_TEST_BUNDLER_URL=
ERC4337_TEST_NODE_URL=
ERC4337_TEST_SINGLETON_ADDRESS=
ERC4337_TEST_SAFE_FACTORY_ADDRESS=
MNEMONIC=
  1. Pre-fund the executor account derived from the mnemonic with some Native Token to cover the deployment of an ERC4337 module and the pre-fund of the Safe for the test operation.

Deployments

A collection of the different Safe contract deployments and their addresses can be found in the Safe deployments repository.

To add support for a new network follow the steps of the Deploy section and create a PR in the Safe deployments repository.

Deploy

:warning: Make sure to use the correct commit when deploying the contracts. Any change (even comments) within the contract files will result in different addresses. The tagged versions that are used by the Safe team can be found in the releases.

Current version: The latest release is v1.3.0-libs.0 on the commit 767ef36

This will deploy the contracts deterministically and verify the contracts on etherscan using Solidity 0.7.6 by default.

Preparation:

  • Set MNEMONIC in .env
  • Set INFURA_KEY in .env
yarn deploy-all <network>

This will perform the following steps

yarn build
yarn hardhat --network <network> deploy
yarn hardhat --network <network> sourcify
yarn hardhat --network <network> etherscan-verify
yarn hardhat --network <network> local-verify
Custom Networks

It is possible to use the NODE_URL env var to connect to any EVM based network via an RPC endpoint. This connection then can be used with the custom network.

E.g. to deploy the Safe contract suite on that network you would run yarn deploy-all custom.

The resulting addresses should be on all networks the same.

Note: Address will vary if contract code is changed or a different Solidity version is used.

Replay protection (EIP-155)

Some networks require replay protection, making it incompatible with the default deployment process as it relies on a presigned transaction without replay protection (see https://github.com/Arachnid/deterministic-deployment-proxy).

Safe contracts use a different deterministic deployment proxy (https://github.com/safe-global/safe-singleton-factory). To make sure that the latest version of this package is installed, make sure to run yarn add @gnosis.pm/safe-singleton-factory before deployment. For more information, including how to deploy the factory to a new network, please refer to the factory repo.

Note: This will result in different addresses compared to hardhat's default deterministic deployment process.

Verify contract

This command will use the deployment artifacts to compile the contracts and compare them to the onchain code

yarn hardhat --network <network> local-verify

This command will upload the contract source to Etherescan

yarn hardhat --network <network> etherscan-verify
