AlpenSign
Cryptographically seal payment authorizations and record them as immutable proof on the Solana blockchain.
Three-Layer Trust Model
1
Genesis Token · Device Identity
The Seeker's soulbound NFT proves the phone is genuine hardware, verified by SKR-staked Guardians through TEEPIN.
2
Bank Credential · Client Identity
The bank issues a credential via Solana Attestation Service (SAS), binding the client to the verified device. Revocable by the bank.
3
Transaction Seal · Payment Authorization
The client reviews and confirms with biometric. The Seeker's secure element signs and AlpenSign posts the proof to Solana. Permanent and immutable.

Security Note
Your Seeker may occasionally request a PIN instead of fingerprint. This is standard Android security behavior — after reboot, timeout, or multiple failed fingerprint attempts, Android requires PIN verification. Both methods satisfy the biometric-level authentication requirement.
