Mobile Payments
A complete mobile payment infrastructure built for the next generation of finance. From Payment Intents to gasless ERC-4337 transactions, everything your users need in the palm of their hand.
Payment Intents
Full lifecycle management with create, submit, and cancel flows. Track every payment from initiation to settlement.
Passkey Authentication
FIDO2/WebAuthn-based passwordless authentication. Biometric login with hardware-backed security for every transaction.
Gasless Transactions
ERC-4337 account abstraction enables gas-free blockchain transactions. Users never need to hold ETH for fees.
Payment Intent Lifecycle
The Payment Intent system provides a structured, auditable approach to mobile payments. Every transaction moves through clearly defined states, enabling robust error handling, compliance checks, and user confirmation flows.
Create Intent
Initialize a payment with amount, currency, recipient, and metadata. The system validates parameters and reserves funds.
Submit Payment
User confirms the payment with biometric or passkey authentication. The system processes the transfer atomically.
Settlement or Cancellation
Payment settles instantly or can be cancelled before submission. Full receipt generation with digital signatures.
