Timeframe

Restrict when a session function can be called. Attach the policy at the function level. Examples on this page use @rhinestone/sdk, where rhinestone is the RhinestoneSDK instance from Create a session with a custom setup.

import { erc20Abi } from "viem";
import { base } from "viem/chains";

const session = await rhinestone.createSession({
  chain: base,
  owners: {
    type: "ecdsa",
    accounts: [sessionOwnerAccount],
  },
  permissions: [
    {
      abi: erc20Abi,
      address: usdcAddress,
      functions: {
        transfer: {
          validAfter: new Date(),
          validUntil: new Date(Date.now() + 1000 * 60 * 60 * 24),
        },
      },
    },
  ],
});

This limits the function to a 24-hour window.
