Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built on audited security patterns and gas-optimized code to ensure reliability and cost-efficiency from day one.
We deliver a fully tested, deployable contract suite in as little as 2 weeks.
Our full-service development includes:
Solidity/Rust development to deployment and upgrade planning.OpenZeppelin libraries, comprehensive unit/integration testing, and pre-audit readiness.ERC-20, ERC-721, ERC-1155, staking, governance, and cross-chain bridges.We focus on long-term maintainability. Every contract includes detailed documentation, a clear upgrade path using proxies like TransparentProxy or UUPS, and integration support for your front-end and backend systems.
We build secure, scalable payment rails that connect your mobile app to the blockchain, handling the technical complexity so you can focus on your business.
Seamless integration of non-custodial wallets (MetaMask, WalletConnect) and custodial solutions. Supports EVM chains (Ethereum, Polygon, Arbitrum) and Solana for maximum user flexibility.
End-to-end payment processing with gas optimization, multi-signature approvals, and real-time status tracking. Built with OpenZeppelin libraries and audited security patterns.
Integrated payment gateways for credit/debit cards and bank transfers. Direct API connections to providers like MoonPay and Stripe for compliant, low-fiat conversion.
Modular KYC/AML checks, transaction monitoring, and sanctions screening. Configurable rules engine to meet regional regulations (FATF Travel Rule, MiCA).
RESTful APIs and mobile SDKs (iOS/Android/Flutter/React Native) with comprehensive documentation, webhook support, and sandbox environments for rapid testing.
Managed node infrastructure with load balancing, automatic failover, and multi-region deployment. Enterprise-grade monitoring, logging, and alerting for operational excellence.
Our mobile B2B crypto payment integration delivers concrete, quantifiable value. We focus on outcomes that directly impact your bottom line and operational efficiency.
Replace 3-5 day ACH/wire delays with near-instant crypto settlement. Automate reconciliation to reduce manual accounting overhead by up to 70%.
Cut out intermediary bank fees and FX conversion spreads. Our optimized routing and gas management ensures you pay the lowest possible network fees.
Enterprise-grade custody, MPC wallets, and automated AML/KYC checks. All integrations are built with security-first principles and undergo third-party audits.
Get to market faster with our modular APIs and SDKs for React Native, Flutter, and native iOS/Android. Full documentation and dedicated technical support included.
Enable B2B payments to and from virtually any country, 24/7/365, without traditional banking limitations. Support for stablecoins (USDC, USDT) and major cryptocurrencies.
Our architecture handles enterprise-scale volume with sub-second latency. Built on battle-tested node infrastructure with automatic failover and load balancing.
Choose the right level of support for your mobile B2B crypto payment integration, from a secure foundation to a fully managed solution.

A structured, transparent approach designed to integrate secure, compliant crypto payments into your mobile B2B platform with minimal disruption and maximum speed.
We conduct a deep-dive technical analysis of your existing stack and business flows to design a modular, scalable integration architecture. This ensures seamless compatibility with your mobile SDKs, backend APIs, and compliance requirements.
Implementation of non-custodial wallet SDKs (Web3.js, Ethers.js) and a robust payment gateway API. We handle multi-chain support (EVM, Solana), gas optimization, and secure transaction signing flows for your mobile app.
Integration of automated compliance checks (KYC/AML via providers like Sumsub) and real-time on-chain monitoring for transaction status, fraud detection, and regulatory reporting. We build the dashboard for your ops team.
Deployment to a staging environment mirroring production. We execute comprehensive testing: unit, integration, penetration, and user acceptance testing (UAT). All smart contracts undergo a formal security review.
Managed deployment to your production infrastructure with zero downtime. We provide full DevOps support: CI/CD pipeline configuration, environment management, and 24/7 monitoring alerts for your payment module.
Delivery of comprehensive technical documentation, API references, and operational runbooks. We conduct training sessions for your engineering and support teams to ensure full ownership and smooth long-term operation.
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts that are secure, gas-optimized, and ready for mainnet. Our development process is built on audited security patterns and battle-tested frameworks like OpenZeppelin and Solmate.
From token standards to complex DeFi logic, we deliver contracts that execute as intended, every time.

A standard integration, including wallet connection, payment processing, and compliance features, typically takes 3-5 weeks from kickoff to production deployment. Complex requirements like multi-chain support or custom settlement logic can extend this to 6-8 weeks. We provide a detailed project plan in the first week.
