A universal app for identity & payments. Smooth, secure, and self-sovereign.
Welcome to the official GitHub organization for Portal: the user-facing interface to a fully decentralized identity and payment protocol. Portal makes it easy for anyone to log in, pay, and prove who they are without passwords or platform lock-in.
🕳️ What Is Portal?
Portal is a digital identity provider built on Nostr and Lightning. It manages your digital identity and public keys, acting as a secure approval layer for sensitive operations:
- ✅ Authorize passwordless logins
- 🤝 Approve single or recurring payments (Lightning & Cashu)
- 🔐 Share zero-knowledge proofs of documents like passports or driver's licenses
Behind the scenes, Portal is a client of a decentralized FOSS protocol we're developing. This protocol powers the logic and trust model — Portal simply gives users a clean, friendly interface to access it all.
🛠️ Built With
We utilize a modern, high-performance stack to ensure security and scalability:
- Core Protocol & Backend: Written in Rust 🦀 for safety, speed, and memory efficiency.
- Client Applications: Built with TypeScript (and Svelte for web demos) to ensure a responsive user experience.
- SDKs & Integrations: implementations available in Java and Rust.
📲 What Can You Do with Portal?
- Log in without usernames or passwords.
- Approve subscriptions and one-time payments with a tap.
- Authenticate in person using your device.
- Link any Nostr Wallet Connect-compatible wallet.
- Manage privacy-preserving e-cash (via Cashu).
- Share proofs of identity without leaking personal data.
Portal doesn’t custody your keys, funds, or data.
