overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built to your exact specifications, from concept to mainnet deployment.

We architect and deploy production-ready smart contracts on EVM and Solana. Our process delivers audit-ready code in 2-4 weeks, ensuring security and gas efficiency from day one.

We don't just write code; we engineer systems that hold real value.

  • Custom Logic: ERC-20, ERC-721, ERC-1155, custom DeFi primitives, and DAO governance.
  • Security-First: Built with OpenZeppelin standards, formal verification, and internal audit passes.
  • Full Lifecycle: Development, testing (Hardhat/Foundry), deployment, and post-launch monitoring.

PROVEN FRAMEWORK

Our Delivery Methodology

We deliver production-ready cross-chain payment gateways through a structured, security-first process that minimizes your time-to-market and technical risk.

01

Architecture & Design Sprint

We begin with a 2-week intensive sprint to define your gateway's multi-chain architecture, token flow, and fee models. This includes threat modeling and selecting optimal bridges (e.g., Axelar, LayerZero) and oracles (Chainlink CCIP).

Cross-Chain Data Payment Gateways

Frequently Asked Questions

Get clear answers on implementation, security, and support for your enterprise-grade payment infrastructure.

A cross-chain data payment gateway is a secure middleware system that enables your application to accept payments and transfer value across multiple blockchains (e.g., Ethereum, Solana, Polygon) while seamlessly integrating with off-chain data sources and traditional payment rails (like Stripe or bank transfers). You need one to eliminate user friction, capture a multi-chain user base, and automate complex financial logic (like paying data providers in stablecoins upon successful API call delivery). Our systems reduce development time for these features from 6+ months to weeks.
