We architect and deploy audit-ready smart contracts on EVM chains (Ethereum, Arbitrum, Polygon) and Solana. Our engineers specialize in Solidity 0.8+, Rust, and Anchor, implementing OpenZeppelin best practices from day one to minimize vulnerabilities and technical debt.
Solana High-Speed Remittance Infrastructure
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
Deliver a secure, functional MVP in as little as 2-4 weeks, not months.
- Custom Logic: DeFi protocols (AMMs, lending/borrowing), NFT collections (ERC-721A, ERC-1155), DAO governance, and enterprise utilities.
- Security-First Development: Integrated testing with
Hardhat/Foundry, formal verification, and pre-audit reviews. - Full Lifecycle Support: From architecture and development to deployment, verification, and post-launch maintenance.
Core Technical Capabilities
Our infrastructure is built on battle-tested Solana primitives, delivering the speed, security, and reliability required for global remittance products.
High-Throughput Transaction Engine
Process thousands of cross-border transactions per second with sub-second finality. Built on Solana's parallel execution (Sealevel) for predictable, low-cost settlements under $0.001.
Enterprise-Grade Security & Compliance
Multi-signature treasury management, on-chain program audits, and real-time monitoring. Integrates with compliance tooling for AML/KYC and transaction screening.
Multi-Chain Liquidity Bridges
Secure, non-custodial bridges to Ethereum, Polygon, and other major chains via Wormhole and Circle CCTP. Enable seamless onboarding and off-ramping for users.
Real-Time FX & On/Off-Ramp APIs
Programmatic APIs for live foreign exchange rates and direct fiat integration. Connect to major payment processors for localized deposits and withdrawals.
Scalable Wallet Infrastructure
Managed MPC wallet solutions with delegated transaction signing. Isolate hot/cold key management and provide non-custodial user experiences.
Dedicated DevOps & 24/7 SRE
Full infrastructure management with 99.9% uptime SLA, automated health checks, and rapid incident response. Includes monitoring dashboards and alerting.
Business Outcomes for Remittance Operators
Our Solana infrastructure delivers measurable improvements in cost, speed, and reliability, directly impacting your bottom line and competitive edge.
Radically Lower Transaction Costs
Leverage Solana's sub-$0.001 transaction fees to reduce your operational costs by over 95% compared to traditional rails or other blockchains. Pass savings to customers or boost margins.
Sub-Second Settlement Finality
Enable near-instant cross-border transfers with Solana's 400ms block times. Eliminate multi-day settlement delays, improving customer satisfaction and unlocking new real-time use cases.
Enterprise-Grade Reliability & Uptime
Deploy on a globally distributed, fault-tolerant validator network. Our managed infrastructure includes monitoring, failover, and a 99.9% uptime SLA to ensure your service is always available.
Regulatory Compliance Framework
Built-in tools for transaction monitoring, address screening (OFAC), and audit trails. Simplify compliance with AML/CFT regulations in multiple jurisdictions using programmable logic.
Seamless Fiat On/Off Ramps
Integrated partnerships with licensed payment processors and banking-as-a-service providers. Offer customers smooth deposits and withdrawals in local currency without managing complex integrations.
Scalable Throughput for Growth
Handle thousands of transactions per second (TPS) on a single, unified ledger. Scale your remittance volume linearly without performance degradation or infrastructure overhauls.

Our Development & Deployment Process
A structured, security-first approach to delivering high-performance Solana remittance infrastructure. We focus on rapid deployment, audited security, and measurable business outcomes.
Architecture & Strategy
We design a tailored Solana architecture using Anchor Framework and SPL Token standards, focusing on transaction throughput, cost efficiency, and regulatory compliance for your target markets.
Smart Contract Development
Development of secure, on-chain logic for cross-border settlement, liquidity pools, and compliance checks. Built with Solidity/Rust, following OpenZeppelin and Solana Cookbook security patterns.
Security & Audit Integration
Rigorous security review integrated into the SDLC. Includes automated analysis, peer review, and optional formal verification with partners like OtterSec or Neodyme.
Testnet Deployment & Simulation
Deploy to Devnet/Testnet for end-to-end testing under realistic load. We simulate high-volume transaction bursts and failure scenarios to ensure system resilience.
Mainnet Launch & Monitoring
Managed deployment to Solana Mainnet with comprehensive monitoring dashboards for transaction success rates, latency, and system health using tools like Helius and SolanaFM.
Scale & Optimization
Post-launch performance tuning and scaling support. We optimize for lower latency and costs, and implement upgrades for new Solana runtime features or protocol changes.
