A module for enabling Schnorr signatures on a Safe account
npm i
cp .env.example .env
The private key you're going to use to deploy the contracts. You will need funds on base sepolia.
Also, this is going to be the signer of the safe account you're going to deploy from the scripts.
SIGNER_PRIVATE_KEY=
The address of your private key
SIGNER_ADDR=
self-explanatory:
BASE_SEPOLIA_RPC=
BASE_SEPOLIA_CHAIN_ID=
Api key from the base sepolia explorer: https://sepolia.basescan.org/
BASE_SEPOLIA_ETHERSCAN_API_KEY=
npx hardhat run ./scripts/deploySafe.ts
Once deployed, please open your .env file and fill in the deployed safe addresses.
SAFE_ADDR=
It is advisable not to use your personal SAFE_ADDRESS here, this repo is for demo purposes.
npx hardhat ignition deploy ignition/modules/DeploySafeSchnorr.ts --network base-sepolia --verify --reset
Once deployed, please open your .env file and file in the safe schnorr module addresses.
MODULE_ADDR=
npx hardhat run ./scripts/enableModule.ts
And we're done!
In order to test it, manually transfer some base sepolia funds to the created SAFE_ADDR. You will need them to run the schnorrExecute script. You're using ~2000 wei per transaction so you don't need a lot.
After you're done, the below script will make paymets to SIGNER_ADDR and a hardcoded test address in the script:
npx hardhat run ./scripts/schnorrExecute.ts
A log of the transaction will appear if everything is successful. Open it in base sepolia etherscan and check it!
The schnorr signatures for this demo are produced by using https://github.com/borislav-itskov/schnorrkel.js
The library can be freely used for Schnorr
In order to try the multisignature version, a little bit of more setup is required. We have to start by entering a second private key in the .env config:
SIGNER_TWO_PRIVATE_KEY=
After we have it set, let's deploy the 2/2 multisig module. It's the same contract but with a different schnorr signer:
npx hardhat ignition deploy ignition/modules/DeployMultiSigSafeSchnorr.ts --network base-sepolia --verify --reset
We enter its contract address in the .env file:
MULTI_SIG_MODULE_ADDR
And use the same address from above to enable the module:
MODULE_ADDR={THE_ADDRESS_FROM_ABOVE} npx hardhat run ./scripts/enableModule.ts
Finally, we run the multisig script:
npx hardhat run ./scripts/schnorrMultisigExecute.ts
