Our Delivery Methodology
We deliver enterprise-grade EVM stablecoin gateways through a structured, transparent process designed for speed, security, and seamless integration into your existing financial stack.
01
Architecture & Strategy Review
We begin with a deep technical assessment of your current infrastructure and target chains (e.g., Ethereum, Polygon, Arbitrum). We define the optimal gateway architecture, token standards (ERC-20, ERC-4626), and cross-chain messaging protocol (LayerZero, Axelar, Wormhole) for your specific use case.

Architecture Expertise
02
Smart Contract Development & Auditing
Our engineers develop custom, gas-optimized smart contracts for minting, burning, and bridging stablecoins. Every contract undergoes rigorous internal review and is submitted for a formal audit by a leading third-party firm (e.g., Spearbit, Code4rena) before deployment.
