MICROPAYMENT ENGINE
Core Features We Build
We architect the foundational components that power seamless, secure, and scalable mobile-first micropayment experiences. Our focus is on delivering production-ready infrastructure that drives user adoption and revenue.
01
Gasless Transaction Layer
Abstract away blockchain complexity with sponsored meta-transactions. Users pay with fiat or stablecoins, eliminating the need for native tokens and onboarding friction.
Key Deliverables:
- ERC-2771 & ERC-4337 Account Abstraction
- Custom Paymaster contracts for fee sponsorship
- Multi-chain gas relay infrastructure

For End-Users
02
Secure Wallet Integration
Embedded non-custodial wallets using MPC (Multi-Party Computation) technology. Users retain full control of assets with a familiar social login or PIN recovery, removing seed phrase complexity.
Key Deliverables:
- MPC-based key management (e.g., Web3Auth, Lit Protocol)
- Biometric & social login flows (Google, Apple)
- In-app balance and transaction history

Non-Custodial
Security Model
03
Real-Time Payment Channels
Enable instant, high-volume microtransactions with near-zero fees using state channels or Layer 2 solutions. Ideal for pay-per-second streaming, in-game economies, and content monetization.
Key Deliverables:
- Custom state channel logic on Arbitrum Nitro or Polygon zkEVM
- Sub-second finality for off-chain settlements
- Fraud-proof dispute resolution systems

Cross-Chain Settlement Hub
Facilitate payments across multiple blockchains (Ethereum, Polygon, Solana) through a unified interface. Users and merchants can transact in their preferred network without manual bridging.
Key Deliverables:
- CCIP or LayerZero-based cross-chain messaging
- Automated liquidity rebalancing across chains
- Single dashboard for multi-chain treasury management
