EOA used to sign the delegation message.
​
params.sessionKeyPair
SessionKeyPair
required
Session keypair generated with generateSessionKeyPair.
​
params.authConfig
AuthConfigV2
required
Resources and expiration scoped to the delegated session.

​
Returns

​
delegationAuthSig
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(),
  },
