Secure, local-first multi-chain wallet management — create wallets, derive addresses, sign messages and transactions across EVM, Solana, XRPL, Sui, Bitcoin, Cosmos, Tron, TON, Spark, Filecoin, Nano, and NEAR via CLI, Node.js, or Python.
Secure, offline-first multi-chain wallet management. Private keys are encrypted at rest (AES-256-GCM, scrypt KDF) and decrypted only after policy checks pass, then immediately wiped from memory — the caller never sees the raw key.
Available as CLI, Node.js SDK (@open-wallet-standard/core), and Python SDK (open-wallet-standard).

# Create a MoonPay deposit (auto-converts to USDC on target chain)
ows fund deposit --wallet "my-wallet" --chain base --token USDC
# Check token balances
ows fund balance --wallet "my-wallet" --chain base
Payments (x402)
# Make a paid request to an x402-enabled API endpoint
ows pay request https://api.example.com/data --wallet "my-wallet"
ows pay request https://api.example.com/data --wallet "my-wallet" --method POST --body '{"key":"value"}'# Discover x402-enabled services from the Bazaar directory
ows pay discover
ows pay discover --query "weather" --limit 10
Policies

ows policy create --file policy.json
# List / show / delete policies
ows policy list
ows policy show --id"policy-id"
ows policy delete --id"policy-id" --confirm
API Keys
# Create an API key for agent access (scoped to wallets + policies)
ows key create --name "claude-agent" --wallet "my-wallet" --policy "policy-id"
ows key create --name "tmp-key" --wallet "my-wallet" --expires-at "2026-04-01T00:00:00Z"# List all API keys (tokens are never shown)
