@openpond/wallet

Viem-first wallet clients for agents using policy-bound OpenPond signing leases.

The package gives application code familiar EVM primitives without placing a private key, Turnkey API key, or reusable signing credential in the runtime. Viem prepares and encodes transaction intents; an OpenPond-compatible lease broker authenticates the runtime, enforces policy, and dispatches signing to the configured wallet provider.

Install

npm install @openpond/wallet viem

OpenPond sandbox

import { createOpenPondWalletFromEnv } from "@openpond/wallet/node";
import { erc20Abi, parseUnits } from "@openpond/wallet";
import { base } from "viem/chains";

const wallet = createOpenPondWalletFromEnv({
  address: "0x...",
  chain: base,
});

const submission = await wallet.writeContract({
  address: "0x...",
  abi: erc20Abi,
  functionName: "transfer",
  args: ["0x...", parseUnits("10", 6)],
});

console.log(submission.requestId);

The Node entrypoint discovers the sandbox's lease proxy URL, short-lived proxy token, team ID, and sandbox ID. It never reads or accepts a Turnkey private credential.

Core API

Use createOpenPondWallet in browsers, workers, tests, and other runtimes where configuration is supplied explicitly.

import { createOpenPondWallet } from "@openpond/wallet";

const wallet = createOpenPondWallet({
  address,
  chain,
  transport,
  lease: {
    proxyUrl,
    proxyToken,
    teamId,
    sandboxId,
  },
});

The context exposes a normal viem public client plus sendTransaction, transfer, and ABI-typed writeContract helpers. Submissions return an honest broker request ID and an optional transaction hash. A Turnkey activity/status ID is never mislabeled as an on-chain hash.

Security model

• No private-key or Turnkey-credential configuration is supported.
• Every write goes through one lease capability request.
• The broker remains responsible for capability, wallet, chain, destination, function, value, expiry, run, and sandbox enforcement.
• The package is not a policy engine and cannot broaden a lease.
