# Sherpa Accounts

When you first access Sherpa, you'll create a ***Sherpa Account***—a smart contract wallet that enables seamless automation while maintaining complete self-custody.

### What Are Sherpa Accounts?

Sherpa Accounts are built on Gnosis Safe's battle-tested SafeCore SDK, enhanced with tailor built modules that enable sophisticated DeFi automation. Think of it as combining the user experience of a centralized exchange with the security guarantees of self-custody.

### Security Model: The OEM

Our ***Onchain Enforcement Mechanism***** (OEM)** ensures we can only execute what you explicitly authorize—nothing more.

When you create an order (a swap, limit order, or strategy), you're cryptographically committing to specific parameters: tokens, amounts, slippage limits, and execution conditions. These commitments are structured as Merkle trees and verified on-chain, ensuring:

* **Integrity** – We cannot modify your order parameters
* **Privacy** – Order details remain confidential until execution
* **Efficiency** – Gas-optimized verification process
* **Defined boundaries** – We can only execute within your exact specifications

This architecture provides the convenience of centralized platforms without the custody risk. We handle execution, but the blockchain enforces your permissions.
