PROVEN PROCESS
Our Delivery Methodology
We deliver production-ready payment gateways through a structured, transparent process designed for speed, security, and seamless integration with your existing e-commerce stack.
01
Discovery & Architecture
We start with a deep dive into your tech stack and business logic to design a scalable, multi-chain architecture. This phase defines token standards (ERC-20, ERC-1155 for NFTs), settlement layers, and integration points with platforms like Shopify or Magento.

02
Smart Contract Development
Our engineers write gas-optimized Solidity/Vyper contracts for payment routing, escrow, and loyalty token mechanics. Every contract follows OpenZeppelin standards and undergoes our internal security review before external audit.
