Playground

This playground contains several scripts that can be used as a starting point to use the Safe{Core} SDK. These scripts do not cover all the functionality exposed by the SDK but showcase some steps of the Safe transaction flow.

Before starting, make sure to install and build the Safe{Core} SDK monorepo.

yarn install
yarn build

Update the config inside the scripts you want to execute and run the following commands for each of them.

Deploy a Safe

This script allows to deploy a new Safe account with any given configuration (number and addresses of the signers, threshold, etc.):

yarn play deploy-safe

Propose a transaction

This script allows a signer of a Safe to share a transaction with the other signers by submitting it to the Safe Transaction Service:

yarn play propose-transaction

Confirm a transaction

This script allows a signer of a Safe to get a proposed transaction from the Safe Transaction Service and confirm it by signing it and submitting its signature:

yarn play confirm-transaction

Execute a transaction

Once there are enough signatures collected for a given transaction in the Safe Transaction Service, this script allows any account to get the transaction and execute it:

yarn play execute-transaction

In case you want to execute the transaction via a transaction relay, this script allows to do that, where the fees are extracted from the Safe balance:

yarn play relay-paid-transaction

In case you want to execute the transaction via a transaction relay, this script allows to to that, where the fees are extracted from a third party account balance that sponsors the transaction:

yarn play relay-sponsored-transaction

Generate a custon Safe address

This script allows to find the right saltNonce to generate a vanity Safe address with any given configuration:

yarn play generate-safe-address
