# generateEoaDelegationAuthSig

# Function

> **generateEoaDelegationAuthSig**(`params`)

Creates a delegation signature for an EOA-based session. The EOA wallet signs the session delegation message directly, enabling pre-generated session materials for server-side reuse.

## Parameters

<ParamField path="params.account" type="Account | WalletClient | Signer" required>
  EOA used to sign the delegation message.
</ParamField>

<ParamField path="params.sessionKeyPair" type="SessionKeyPair" required>
  Session keypair generated with `generateSessionKeyPair`.
</ParamField>

<ParamField path="params.authConfig" type="AuthConfigV2" required>
  Resources and expiration scoped to the delegated session.
</ParamField>

## Returns

<ResponseField name="delegationAuthSig" type="AuthSig">
  Delegation signature that can be paired with the session keypair.
</ResponseField>

## Example

```ts theme={null}
import {
  generateEoaDelegationAuthSig,
  generateSessionKeyPair,
} from '@lit-protocol/auth';

const sessionKeyPair = generateSessionKeyPair();

const delegationAuthSig = await generateEoaDelegationAuthSig({
  account: myViemAccount,
  sessionKeyPair,
  authConfig: {
    resources: [ ['lit-action-execution', '*'] ],
    expiration: new Date(Date.now() + 10 * 60 * 1000).toISOString(),
  },
});
```
