The canonical versions of the Safe smart contracts are deployed to the following networks:
Ethereum Mainnet (Etherscan provides a good overview here.)
Ethereum Testnets: Rinkeby, Kovan, Ropsten, Görli
Gnosis Chain (formerly xDai)
Binance Smart Chain
Energy Web Chain
Energy Web Chain Testnet: Volta
The contract addresses match on all these networks. The full list can be found in the Safe deployments repository on Github (e.g. for v.1.3.0).
To deploy the Safe contracts version 1.3.0 on another EVM-based chain, follow the instructions in the safe-contracts repository. Please note: The chain needs to be fully compatible, i.e. support all opcodes used by the Safe contracts.
The Safe team does not have the capacity to spin up and maintain full frontend and backend support for all EVM-based networks. All Safe related source code is open source. We encourage everyone to deploy the canonical versions of the Safe contracts to their respective networks and run the required backend and frontend parts themselves.
