@functornetwork/agentic-wallet

TypeScript SDK for creating non-custodial agentic wallets with on-chain session-key delegation.

npm install @functornetwork/agentic-wallet viem

Quick start

Create a client for the chains you want. Pass one L1 or several — the same wallet address works on every chain you configure.

import { createClient, SEPOLIA, BNB_TESTNET } from "@functornetwork/agentic-wallet";

// Both L1s, or just one — your choice.
const client = createClient({ chains: [SEPOLIA, BNB_TESTNET] });

Passkey wallet (browser)

const wallet = await client.createPasskeyWallet({ name: "My Agent Wallet" });

Private-key wallet (server / agent)

import { signerFromPrivateKey } from "@functornetwork/agentic-wallet";

const signer = signerFromPrivateKey(process.env.PRIVATE_KEY);
const wallet = await client.createWallet({ signer });

Grant a session and execute

Operations take an optional chainId (defaults to the client's first chain):

const session = await client.grantSession({
  wallet,
  signer,
  permissions: {
    calls: [{ to: "0x…" }],
    spend: [{ limit: 1_000_000n, period: "day" }], // 1 USDC/day
  },
  expiry: Math.floor(Date.now() / 1000) + 60 * 60, // 1 hour
});

await client.execute({
  session,
  chainId: 97, // BNB testnet; omit to use the default chain
  calls: [{ to: "0x…", value: 0n, data: "0x…" }],
});
