## Automatic Protocol Access

Your wallet is future-proof. When new protocols are integrated:

* No migration needed
* No wallet updates required
* Automatically available through new Lego deployments
* All existing security settings still apply

**Live data**: See all active integrations and their onchain status in the [Params Explorer](https://params.underscore.finance/legos).

## Protocol Safety

All integrated protocols are:

* Established with significant TVL
* Audited by reputable security firms
* Battle-tested on mainnet

Underscore only integrates protocols that meet strict security standards.

## What Are Legos?

Legos are standardized adapters that give your wallet access to each protocol. They handle the complexity of interacting with different smart contracts behind a consistent interface.

**Benefits of the Lego architecture**:

* **Simplicity**: One interface for all protocols
* **Safety**: Audited adapters with built-in protections
* **Future-proof**: New protocols work automatically
* **Composability**: Combine operations across protocols in single transactions
