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.
ERC-20, ERC-721, ERC-1155, custom DeFi primitives, and DAO governance.OpenZeppelin standards, formal verification, and internal audit passes.Hardhat/Foundry), deployment, and post-launch monitoring.We build secure, scalable payment gateways that abstract away cross-chain complexity, enabling you to focus on your core product.
Intelligent, gas-optimized routing across EVM, Solana, and Cosmos chains. Our system automatically selects the fastest and most cost-effective path for each transaction, reducing user friction and failed payments.
End-to-end transaction lifecycle management with atomic settlement guarantees. Built with audited smart contracts and MPC/TSS custody solutions to eliminate counterparty risk and ensure funds are never at rest.
Reliable price feeds and state verification from multiple decentralized oracle networks (Chainlink, Pyth, API3). Ensures accurate, tamper-proof settlement rates and prevents front-running or manipulation.
REST & WebSocket APIs with comprehensive documentation, rate limiting, and 24/7 monitoring. Enables seamless integration into your existing payment flows, dashboards, and accounting systems.
Built-in transaction screening (OFAC, AML), real-time analytics dashboards, and automated alerting for anomalous activity. Provides the visibility and control required for regulated FinTech operations.
Flexible fee models including meta-transactions and paymaster integrations. Allows you to sponsor user gas fees or offer fixed-fiat pricing, dramatically improving the end-user payment experience.
Our cross-chain payment gateway is engineered to deliver measurable improvements in revenue, user acquisition, and operational efficiency. Here’s what you can expect.
Unlock revenue from users on any major blockchain (Ethereum, Solana, Polygon, etc.) without building custom bridges. We handle the cross-chain complexity, so you can focus on your data product.
Enable one-click purchases with stablecoins or native tokens. Our gas abstraction and meta-transaction systems eliminate the need for users to hold specific gas tokens, dramatically boosting conversion.
Every data purchase is secured by audited, non-custodial smart contracts. Funds are atomically settled; you receive payment instantly upon data delivery, with zero counterparty risk.
Our infrastructure is built for enterprise reliability. Automated failover, multi-region node deployment, and 24/7 monitoring ensure your marketplace is always available for transactions.
Go from zero to a fully functional, white-labeled payment gateway in weeks, not months. We provide SDKs, comprehensive docs, and dedicated technical support for a seamless integration.
Access a unified dashboard with real-time analytics on cross-chain transaction volume, user demographics, and revenue streams. Make data-driven decisions to optimize pricing and growth.

We deliver production-ready cross-chain payment gateways through a structured, security-first process that minimizes your time-to-market and technical risk.
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).
Our team builds and unit-tests your core payment router and escrow contracts in Solidity 0.8+ using OpenZeppelin libraries. We implement gas-efficient patterns and comprehensive access controls from day one.
We handle the complex integration with your chosen cross-chain messaging protocols and liquidity bridges. This includes setting up secure relayers, configuring gas management, and implementing failover mechanisms.
Every gateway undergoes an internal audit against our 150+ point security checklist, followed by a formal review from a third-party auditor like CertiK or Halborn before mainnet deployment.
We deploy to testnets, conduct integration testing, and then execute a phased mainnet rollout. 24/7 monitoring with Chainscore's dashboard tracks transaction success rates, bridge health, and anomaly detection.
You receive complete technical documentation, operational runbooks, and admin key management procedures. We provide ongoing support and scaling guidance for adding new chains or payment methods.
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that power your core business logic. Our development process ensures security-first design, gas optimization, and audit readiness from day one.
Solidity/Rust contracts for DeFi, NFTs, DAOs, and enterprise applications.OpenZeppelin standards, formal verification, and comprehensive test suites.Reduce your time-to-market with battle-tested contracts that have secured over $500M in on-chain value.
We deliver production-ready code within 2-4 weeks for an MVP, backed by a 99.9% uptime SLA post-launch. Our contracts are designed for future upgrades and compliance with evolving regulations like MiCA.

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.
