issueSessionKey

issueSessionKey(params): Promise<KawasekitSessionEnvelope>

Defined in: src/session/issue.ts:102

Issues a fresh session key for an agent smart account.

Notes:

• The session-key private key is not embedded in the returned envelope. The agent must receive the private key out-of-band; the envelope alone is not enough to spend.
• The smart account is not deployed by this call. It will be deployed on first userOp from restoreSessionAccount.

Parameters

params

IssueSessionKeyParams

Returns

Promise<KawasekitSessionEnvelope>

Example

import { parseUnits } from "viem";
import { privateKeyToAccount } from "viem/accounts";
import {
  createJpycDailyLimitPolicies,
  getJpycAddress,
  issueSessionKey,
  JPYC_DECIMALS,
  polygonAmoy,
  serializeSessionEnvelope,
} from "kawasekit";

const owner = privateKeyToAccount(process.env.OWNER_PRIVATE_KEY as `0x${string}`);
const sessionKey = privateKeyToAccount(process.env.SESSION_KEY_PRIVATE_KEY as `0x${string}`);

const envelope = await issueSessionKey({
  publicClient,
  ownerSigner: owner,
  sessionKeySigner: sessionKey,
  policies: createJpycDailyLimitPolicies({
    jpycAddress: getJpycAddress(polygonAmoy.id),
    maxPerTransfer: parseUnits("100", JPYC_DECIMALS),
    maxTransfersPerDay: 10,
  }),
  policySummary: {
    jpycAddress: getJpycAddress(polygonAmoy.id),
    maxPerTransfer: parseUnits("100", JPYC_DECIMALS),
    maxTransfersPerDay: 10,
  },
});
