EVM SDK | Asigna

Asigna leverages Safe Global's EVM smart contract multisig logic, allowing full compatibility with Safe's SDK. This enables you to access all of Safe's features seamlessly. For more details, refer to their documentation .

To initialize the SDK, you'll need the Asigna contracts addresses deployed on your target network and the corresponding Asigna Transaction Service API URLs.
