OWS - Open Wallet Standard

Local-first, multi-chain wallet management for AI agents. By MoonPay.

Prerequisites

OWS CLI (ows) must be pre-installed by the user. This skill does not install software. See https://openwallet.sh for installation instructions.

When to Use

  • Checking wallet balances
  • Signing transactions or messages
  • Making x402 payments to paid APIs
  • Querying wallet info

CLI Reference

# Wallet info
ows wallet list                    # List all wallets
ows wallet info                    # Show vault path + supported chains

# Balances
ows fund balance --wallet <name> --chain <chain>   # Check balance (base, ethereum, solana, etc.)

# Signing
ows sign message --wallet <name> --chain <chain> --message <msg>
ows sign tx --wallet <name> --chain <chain> --tx <hex>

# x402 payments
ows pay request --wallet <name> <url>       # Pay an x402-enabled API
ows pay discover <url>                       # Discover x402 services

Node.js SDK

import { signMessage } from "@open-wallet-standard/core";

const sig = signMessage("my-wallet", "evm", "hello");

Supported Chains

EVM (Ethereum, Base, Polygon, Arbitrum), Solana, Bitcoin, Cosmos, Tron, TON, Sui, Filecoin, Spark. All derived from a single BIP-39 seed via CAIP-2 chain identifiers.

Security Model

  • Keys encrypted at rest (AES-256-GCM)
  • Keys decrypted only during signing, wiped from memory immediately after
  • Pre-signing policy engine for spending limits and chain allowlists
  • The OWS API never returns raw private keys
  • Append-only audit log

Important

  • Never ask for or handle raw private keys. OWS signs internally.
  • Do not install or update OWS packages. Only use pre-installed CLI.
  • See https://openwallet.sh for full documentation.
