What are Smart Account Modules
Modules are self-contained smart contracts that extend a smart account's feature set. This creates a new paradigm for developers to access the programmable validation and execution of smart accounts, unlocking new product capabilities without compromising user self-sovereignty.
There are four types of modules today:
- Validators: Allow developers to modify how transactions are authenticated or what can be authorized against an account. This can unlock powerful features like session keys or quantum-proof signatures.
- Executors: Allow developers to create executions on an account with custom logic. This, for example, can unlock portfolio management products like a take profit or stop loss feature on a DeFi platform. ZK Email (opens in a new tab) is a novel example of how powerful and versatile an executor can be.
- Hooks: Allow developers to augment a smart account's execution flow by hooking in pre- or post-execution and enforcing conditions or any custom logic. A simple example is a spending limit.
- Fallbacks: Extend the account logic to add more functionality. For example, this can allow an account to be compatible with new module types in the future.
