This is a straightforward guide and just shares how you can exactly deploy the same Gnosis Safe with the exact same address to multiple networks.
Here is a list of all the things that you need:
- The address of the gnosis safe that you intend to use
- The tx hash link of the gnosis safe contract creation with the address you are intending to use
- The access of the deployer's account whom have deployed the gnosis safe contract with the same address you are intending to use
- Some native funds in those specific networks to cover for the cost of contract deployment
- Enabled MetaMask custom hex data when sending a transaction
In order to demonstrate it in this guide, I have to have a proof that it works.
- Update your MetaMask's settings, by enabling custom hex data input when sending transactions to an arbitrary address.
- Given that I have a deployed safe on Polygon which can be found in this transaction here with address 0xCF...faFb, open the tx hash link to find the relevant data we need.
- Open MetaMask in a browser tab and click "Send"
- Now get the "To" address from the transaction link and place it in the input field under "Send To". In this case our recipient should be "0xa6b71e26c5e0845f74c812102ca7114b6a896ab2"
- Next is we fill in the custom hex input data, we'll get that from our previous transaction link. In the transaction details, click "Click to see more" and find "Input Data" section, then change the formatting view to "Original". It'll look something like this. When you find it, copy the entire hex data.
- Now back to our MetaMask tab, once you copy the hex data from the transaction, let's fill in the "Hex data" input field. Then finally click "Next".
- MetaMask will also check itself if the transaction can go through or not. Other than that best way to find out is just to make the transaction, so click "Confirm"
- To confirm if it was a success, open Gnosis Safe dashboard and check in the side panel if the safe was already created using the same address in a different network.
In this guide, we've managed to deploy the same address of a Gnosis Safe that was deployed previously on Polygon Mainnet and have also an existing chain on Avalanche.
If by any chance you have any questions you want to clarify, you can hit me up on Twitter, or in any form of communication medium.
Thanks for making it up here until the end, I hope this helps you! 🤝🎉
