Open Wallet Standard
Open Wallet Standard (progetto open source)
Data verified on unchanged since the sources
Worth it if you are a developer who wants to give an AI agent a non-custodial multi-chain wallet with local keys and policy-gated signing, from a single seed (BTC, ETH, SOL, ATOM, TON, TRON).
Avoid it if you want a ready-made product with support: it is an open source standard in early adoption, with no accountable entity if something breaks, and not for end users.
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.
On the Sovereignty lens the score is 4.9/5 (outstanding): the strength is privacy & anonymity (5.0/5), while censorship resistance (4.5/5) is the weak link.
