We meet with your team to understand your specific needs - whether it's migrating from Auth0, adding Bitcoin payments, or building a new Web3 product. We assess your current infrastructure and design a custom integration plan.
Our engineers configure the KeyAuth Protocol for your use case - setting up OAuth scopes, covenant structures, PoF thresholds, and privacy levels. We provide sandbox environments for testing before production.
Seamless integration with your existing systems via our RESTful API, WebSocket endpoints, or OAuth2/OIDC flows. We handle data migration from legacy auth providers with zero downtime.
Go live with 24/7 monitoring, dedicated support, and continuous optimization. We provide analytics dashboards, security audits, and proactive scaling recommendations.
Built for enterprise, secured by Bitcoin
Users never give up control of their Bitcoin. All verification happens via PSBT and signatures - no custody, no counterparty risk.
Multiple privacy levels (boolean/threshold/aggregate). Prove holdings without revealing exact amounts. Pseudonymous by default.
LNURL-auth for instant onboarding. WebSocket real-time updates. Sub-second authentication flows.
OAuth2, OpenID Connect, LNURL, PSBT - we speak the language of both Web2 and Web3.
Real economic cost to create accounts. Proof-of-funds as spam protection. Covenant-based access control.
99.9% uptime SLA. SOC 2 compliant. Comprehensive audit logs. 24/7 support for critical deployments.
