Open Wallet Standard
Open Wallet Standard (progetto open source)
Open Wallet Standard (OWS) is an open standard for secure local wallet storage and agent access. It defines a unified local storage format to create, sign and manage wallets securely across any tool and chain: keys live in a local folder (~/.ows/) rather than in a browser extension, the cloud, or scattered across tool-specific configs. From a single seed you can derive BTC, ETH, SOL, ATOM, TON and TRON addresses, and the API never returns raw private keys. It gives AI agents a common wallet layer with local key control (policy-gated signing). It is an open source project, not a company: no custody of funds.

Verdict
Score 3.0/5, average profile. In its favour: non-custodial by design: keys stay local and the API never exposes private keys. The trade-off to weigh: it is a standard/OSS, not a managed product or service with support.
