Frequently Asked Questions

FAQPage Schema
How to install Open Wallet Standard?▼

Run `npx skills add open-wallet-standard/core --all -g -y` in your terminal to install the skill globally. You also need the `ows` CLI, available via npm or the one-line installer at docs.openwallet.sh.

Which blockchains does OWS support?▼

OWS signs on EVM chains, Solana, Bitcoin, Cosmos, Tron, TON, Sui, Spark, Filecoin, XRPL, NEAR, and more, all from a single wallet with one mnemonic.

Are private keys ever exposed when signing?▼

No. Keys stay encrypted at rest with AES-256-GCM, are decrypted only after policy checks pass, and are wiped from memory immediately after signing.

Can I control what an automated agent can do with my wallet?▼

Yes. You can register policies with chain allowlists and expiry, then issue scoped API keys that gate every signing request before decryption.

Does OWS work with Node.js and Python?▼

Yes. It ships native SDKs for Node.js (`@open-wallet-standard/core`) and Python (`open-wallet-standard`), plus a full CLI, all backed by the same Rust core.
