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

Account | WalletClient | Signer

required

EOA used to sign the delegation message.

SessionKeyPair

required

Session keypair generated with generateSessionKeyPair.

AuthConfigV2

required

Resources and expiration scoped to the delegated session.

Returns

AuthSig

Delegation signature that can be paired with the session keypair.

Example

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(),
  },
});
