Safe Singleton Factory

Singleton factory used by Safe related contracts based on https://github.com/Arachnid/deterministic-deployment-proxy

The original library used a presigned transaction without a chain id to allow deployment on different chains. Some chains do not allow such transactions to be submitted (e.g. Celo and Avalanche) therefore this repository will provide the same factory that can be deployed via a presigned transaction that includes the chain id. The key that is used to sign is controlled by the Safe team.

Adding new networks

To add support for new networks the same key used for the existing networks should be used to generate a presigned transaction for a new network. To request support for a new network please open a new issue.

To generate the deployment data for a new network the following steps are necessary:

• Set RPC in the .env file for the new network

• Estimate transaction params via yarn estimate

• Set MNEMONIC in the .env file

• Run yarn compile <chain_id> [--gasPrice <overwrite_gas_price>] [--gasLimit <overwrite_gas_limit>]

To do estimate and compile steps together:

• Run yarn estimate-compile ["$RPC"]

For zkSync

• Set MNEMONIC or PK in the .env file
• Run yarn compile:zk

Expected Addresses

For all networks the same deployer key is used. The address for this key is 0xE1CB04A0fA36DdD16a06ea828007E35e1a3cBC37.

This results in the address for the factory to be 0x914d7Fec6aaC8cd542e72Bca78B30650d45643d7 for all bytecode compatible EVM networks.

For zkSync based networks the same deployer is used and expected factory address is 0xaECDbB0a3B1C6D1Fe1755866e330D82eC81fD4FD.

Note: For zkSync the factory is deployed using the create2 method of the system deployer using the zero hash (0x0000000000000000000000000000000000000000000000000000000000000000).
