# createEvmEip7702Delegation

```ts theme={null}
function createEvmEip7702Delegation(options: CreateEvmEip7702DelegationOptions): Promise<CreateEvmEip7702DelegationResult>;
```

Creates an EIP-7702 delegation for an end user's EVM EOA account, upgrading it with smart account capabilities.

This endpoint retrieves delegation artifacts from onchain, signs the EIP-7702 authorization,
submits a Type 4 transaction, and creates an associated smart account object. After success,
the local auth state is refreshed so the new smart account appears in the user's account list.

## Parameters
