MEV-Resistant Transaction API
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your protocol.
- End-to-End Development: From ideation to deployment on
EVM-compatible chains (Ethereum, Polygon, Arbitrum). - Security Audits: Multi-stage reviews using
SlitherandMythX, plus third-party auditor coordination. - Gas Optimization: Achieve up to 40% lower transaction costs through efficient code patterns and storage design.
- Upgradeability: Implement secure proxy patterns (
TransparentProxy,UUPS) for future-proof contracts.
We deliver battle-tested code that handles real value, with a zero critical-bug track record in production.
Core Technical Capabilities
Our MEV-Resistant Transaction API is engineered for high-throughput applications requiring predictable execution and maximum value capture. We deliver the infrastructure, you focus on your product.
Private Transaction Routing
Route transactions through a private mempool to shield them from front-running and sandwich attacks before they reach the public network. Protects user funds and ensures fair execution.
Gas Optimization Engine
Dynamic gas estimation and bundling that adapts to real-time network conditions. Our algorithms minimize costs while ensuring timely inclusion, even during volatile periods.
Multi-Chain Execution
Seamless, unified API for submitting MEV-resistant transactions across Ethereum, Arbitrum, Optimism, and Base. One integration, consistent behavior across all supported chains.
Real-Time Simulation & Analytics
Pre-flight transaction simulation with detailed analytics on potential MEV exposure, success probability, and cost breakdown. Make informed decisions before broadcasting.
Enterprise-Grade Reliability
Built on fault-tolerant, geographically distributed infrastructure. Includes 24/7 monitoring, alerting, and a 99.9% uptime SLA for mission-critical financial applications.
Compliance-Ready Architecture
Configurable transaction policies, detailed audit logs, and non-custodial design. Meets the operational security and compliance requirements of institutional clients.
Business Outcomes for Your dApp
Our MEV-Resistant Transaction API delivers concrete technical and commercial advantages, directly impacting your dApp's security, user experience, and bottom line.
Eliminate Front-Running & Sandwich Attacks
We implement private transaction pools, encrypted mempools, and strategic timing to shield your users' trades from predatory MEV bots. This directly protects user funds and ensures fair execution prices.
Maximize User Yield & Slippage Protection
Our system actively seeks optimal routing and execution timing to capture positive MEV (like arbitrage) for your users, not against them. This results in better swap rates and higher effective yields for liquidity providers.
Guaranteed Transaction Finality
Stop worrying about failed transactions due to volatile gas prices or network congestion. Our API includes dynamic gas estimation and priority bundling to ensure your users' critical transactions are confirmed.
Reduce Gas Costs by up to 40%
Intelligent batching, gas optimization algorithms, and access to private order flow reduce the effective gas cost per user transaction, directly lowering the barrier to entry and improving retention.
Deploy in Days, Not Months
Get a production-ready, white-labeled MEV protection layer integrated with your dApp's front-end and smart contracts in under two weeks. We handle the complex infrastructure so you can focus on product.

Our Delivery Methodology
We deliver production-ready MEV-Resistant Transaction APIs through a structured, security-first development lifecycle designed for enterprise-grade reliability and rapid integration.
Architecture & Threat Modeling
We begin with a comprehensive security assessment, analyzing your specific transaction patterns and threat vectors to design a custom MEV-resistant architecture. This includes defining privacy guarantees, validator selection logic, and failover mechanisms.
Protocol-Agnostic Integration
Our API is built to work seamlessly across EVM chains (Ethereum, Arbitrum, Polygon) and Solana. We handle the complexities of RPC endpoints, gas estimation, and chain-specific transaction formats, providing a unified interface.
Implementation & Hardening
We develop the core relayer infrastructure, private mempool logic, and simulation engines using battle-tested libraries. Every component undergoes rigorous internal testing, including adversarial simulation and edge-case validation.
Staged Deployment & Monitoring
We deploy to a staging environment matching mainnet conditions for final validation. Post-launch, we provide 24/7 monitoring dashboards for transaction success rates, latency, and MEV capture attempts, with automated alerts.
Smart Contract Development
Secure, audited smart contract development for DeFi, NFTs, and enterprise applications.
We architect and deploy production-grade smart contracts that form the trustless backbone of your Web3 application. Our development process is built on security-first principles, utilizing OpenZeppelin libraries and rigorous testing frameworks to mitigate risk before mainnet deployment.

Frequently Asked Questions
Get clear answers on how our API protects your users and integrates with your stack.
Our API bundles and submits transactions through a proprietary network of private, trusted validators and searchers. We use cryptographic commit-reveal schemes and fair ordering protocols to prevent front-running, sandwich attacks, and other forms of extractable value. This ensures your users get the execution price they see, with no hidden slippage from bots.
