Documentation · Support · Video walkthrough · Issues OpenSigner is currently being audited by Quantstamp. --- The Problem Most “embedded wallet” providers still hold or fully control user keys behind closed, SaaS‑only infrastructure. That creates single points of failure, vendor lock‑in, and unclear custody: if the vendor goes down, changes terms, or is compromised, your users’ wallets are at risk. At the same time, building your own key management layer is hard: you need secure key storage, recovery flows, multi‑device support, and a clean way to plug into existing auth — all without ever taking custody of users’ keys. The Solution OpenSigner is an open‑source, self‑hostable wallet key management system for non‑custodial wallets. It issues, stores, and recovers cryptographic keys for your users while keeping the signing layer completely under your control — and portable across wallet providers. Core pillars: 1. Threshold key management – Private keys are split into shares (device, hot, cold) using Shamir’s Secret Sharing and only reconstructed ephemerally in memory for signing. 2. Vendor‑neutral architecture – Separate the key management and signing layer from any specific wallet SaaS so you can start on Openfort’s cloud, self‑host, or migrate between providers without moving keys. 3. Auth‑agnostic UX – Plug into your existing auth (OIDC, passkeys, email, etc.) to turn any user account into a non‑c","default_branch":null,"files":null,"tree":[],"storefront":"/r/openfort-xyz","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/openfort-xyz/opensigner/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
