QSEL Authenticator
The world's first NFT-controlled authenticator. Replace passwords and JWTs with compressed NFTs on Solana.
Security Features
Biometric + Quantum Signatures
Every approval requires biometric verification and generates a quantum-resistant cryptographic signature. No one can approve on your behalf.
On-Chain Linking NFT
A compressed NFT minted on Solana creates a cryptographic bond between your authenticator and your Quantum Follis vault. Tamper-proof and verifiable.
Partner Linking NFT
Each website you authenticate with gets its own on-chain bond. This means the website can verify your identity without ever seeing your private key.
QR Code & Deep Link
Scan a QR code on desktop, or tap a deep link on mobile. The flow adapts to your device automatically — no configuration needed.
Connected Sites Manager
View all sites you've authenticated with, see which have on-chain bonds, and revoke access with one tap. Full control over your digital identity.
Session NFT Tokens
Each login session is a compressed NFT in a Merkle tree on Solana. Sessions are time-limited, revocable, and cryptographically verifiable.

Easy Migration
Drop-in SDK replaces your existing auth. Keep your backend, just swap the session layer. Works with Next.js, React, Vue, and any framework.
Transparent Pricing
Free tier for up to 1,000 authentications/month. Scale pricing based on session volume. No hidden fees, no per-user charges.
Zero Liability
No passwords to store means no passwords to breach. Session tokens live on Solana, not in your database. Eliminate your #1 attack vector.
