Some contracts require that the Solidity compile target is petersburg
(e.g. ProxyFactory and MultiSend). This is default since Solidity 0.5.5.
Note: The formal verification was performed using the contract compiled with solcjs 0.5.0.
Preparation:
- Set
INFURA_TOKEN
in.env
- Set
NETWORK
in.env
- Run
npx truffle compile
OpenZeppelin SDK:
- Make sure that @openzeppelin/cli is version 2.5 (
npx oz --version
) - Make sure that all dependencies use solcjs >0.5.0
- Set correct version in
package.json
- Set
MNEMONIC
in.env
to current oz package owner (last deployer normally) - Optional: if a new deployer account is used
- Check that a gloabl versionb of truffle 5 is installed (
truffle version
) - Run
truffle exec scripts/change_oz_owner.js --network=<network> --newOwner="<address>"
to enable new deployer - Set
MNEMONIC
in.env
to new oz package owner
- Check that a gloabl versionb of truffle 5 is installed (
- Run
npm run deploy-oz
- Once deployed on all networks run
npx oz --freeze <network>
for each network
Truffle:
- Set
MNEMONIC
in.env
npx truffle deploy
Verify Contracts:
- requires installed solc (>0.5.0)

You can create a gnosis safe upgradeable instance using OpenZeppelin SDK by linking to the provided EVM package. This will use the master copy already deployed to mainnet, kovan, or rinkeby, reducing gas deployment costs.
To create an instance using OpenZeppelin SDK:
$ npm install -g @openzeppelin/sdk
$ oz init YourProject
$ oz link @gnosis.pm/safe-contracts
$ oz push --network rinkeby
> Connecting to dependency @gnosis.pm/safe-contracts 1.0.0
$ oz create @gnosis.pm//GnosisSafe --init setup --args "[$ADDRESS1,$ADDRESS2,$ADDRESS3],2,0x0000000000000000000000000000000000000000,\"\"" --network rinkeby --from $SENDER
> Instance created at SAFE_ADDRESS
It is suggested to use a non-default address as $SENDER
.
Note: When using the contracts via ZeppelinOS make sure to choose an appropriate Proxy admin. An upgradable proxy enables the user to update the master copy (aka implementation). The default upgradable proxy is managed by an admin address. This admin address is independent from the owners of the Safe. Therefore it would be possible for the admin to change the master copy without the approval of any owner, thus allowing him to gain full access to the Safe.
