@daydreamsai/saw

Node.js client for Secure Agent Wallet (SAW). Simple Unix socket API to sign EVM/Solana payloads without exposing private keys.

Prerequisite: The SAW daemon (saw-daemon) must be installed and running. See the main README for setup instructions.

Install

npm install @daydreamsai/saw

Quickstart

import { createSawClient } from "@daydreamsai/saw";

const saw = createSawClient();

const address = await saw.getAddress();
console.log("wallet:", address);

const sig = await saw.signEip2612Permit({
  chain_id: 1,
  token: "0x1111111111111111111111111111111111111111",
  name: "USD Coin",
  version: "2",
  spender: "0x2222222222222222222222222222222222222222",
  value: "1000000",
  nonce: "0",
  deadline: "9999999999",
});

console.log(sig);

Configuration

Defaults are zero-config. Override if needed:

• SAW_SOCKET (default ~/.saw/saw.sock)
• SAW_WALLET (default main)

const saw = createSawClient({
  socketPath: "~/.saw/saw.sock",
  wallet: "main",
});

API

• getAddress()
• signEvmTx(payload)
• signSolTx(payload)
• signEip2612Permit(payload)

Policy Notes

If allowlist_addresses is set, both token and spender must be allowed for permit signing.

Node Only

This client uses Unix domain sockets and is intended for Node.js environments.
