The vision for Safe Smart Accounts is to become the standard core used in all smart contract-based wallets. It also aims to make the benefits of Account Abstraction accessible to users and developers.
The architectural design of Safe Smart Account keeps the following principles in mind:
- Secure default
- Uses a multi-signature logic where a threshold of owners must confirm a transaction before execution to provide a secure default without trusting any additional contract. For example, a module, guard, or fallback handler (explained below).
- Minimal gas costs
- Optimises gas costs by storing the transaction data that should be executed and the confirmations off-chain.
- Uses a proxy pattern to reduce setup costs.
- Maximum flexibility
- Support Modules are contracts that can use alternative access patterns (instead of multi-signature) to execute transactions.
- Supports the
delegatecallfunction, which introduces complex execution logic by loading instructions from other contracts and executing via a Safe Smart Account.
Here are some core components of a Safe Smart Account that you will learn about:
