| description | 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. |
| version | 1.3.2 |
| metadata | {"openclaw":{"requires":{"anyBins":["ows","node","python3"]},"emoji":"🔑","homepage":"https://openwallet.sh","os":["darwin","linux"],"install":[{"kind":"node","package":"@open-wallet-standard/core","bins":["ows"],"label":"Install OWS Node.js SDK + CLI"}]}} |
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).
Use this skill when the user asks to:
@open-wallet-standard/core or open-wallet-standard in code| Chain | Parameter | Curve | Address Format |
|---|---|---|---|
| EVM (Ethereum, Polygon, Base, etc.) | evm | secp256k1 | EIP-55 checksummed |
| Solana | solana | Ed25519 | base58 |
| Bitcoin | bitcoin | secp256k1 | BIP-84 bech32 |
| Cosmos | cosmos | secp256k1 | bech32 |
| Tron | tron | secp256k1 | base58check |
| TON | ton | Ed25519 | raw/bounceable |
| Sui | sui | Ed25519 | 0x + BLAKE2b-256 hex |
| Spark (Bitcoin L2) | spark | secp256k1 | spark: prefixed |
| XRPL | xrpl | secp256k1 | Base58Check (r...) |
| Filecoin | filecoin | secp256k1 | f1 secp256k1 |
| NEAR | near, near-testnet | Ed25519 | implicit hex (64 chars) |
