ARCHITECTURE & ENGINEERING
Core Technical Capabilities
Our MEV-Resistant Cross-Chain Routing Design is built on a foundation of battle-tested engineering principles, delivering secure, efficient, and reliable interoperability for your application.
03
Intent-Based Routing & Auction Design
We design systems that match user intents (e.g., "swap X for Y at best price") with solvers in a sealed-bid, MEV-resistant auction. This prevents front-running and ensures users get optimal execution across all connected liquidity pools.

Relayer Infrastructure & Incentives
We build and manage high-availability, fault-tolerant relayers with economic security models. Relayers are incentivized for liveness and penalized for malicious behavior, ensuring reliable message delivery without centralized control.

Security-First Development Lifecycle
Every component undergoes formal verification, multiple audit rounds (including firms like Trail of Bits & OpenZeppelin), and rigorous testing (fuzzing, invariant testing). We deliver production-ready code with comprehensive security guarantees.

MEV-RESISTANT CROSS-CHAIN ROUTING
Business Outcomes for Your Protocol
Our MEV-resistant cross-chain routing design delivers measurable improvements to protocol security, user experience, and operational efficiency. These are the concrete outcomes you can expect.
01
Eliminate Front-Running & Sandwich Attacks
We implement cryptographic commit-reveal schemes and private mempool integrations to shield user transactions from predatory MEV bots. This protects your users' swap execution and preserves protocol trust.

02
Optimize Cross-Chain Swap Execution
Our routing algorithms dynamically source liquidity across 10+ EVM and non-EVM chains, minimizing slippage and maximizing fill rates. Users get better prices without manual chain-hopping.

Slippage Reduction
>95%

03
Reduce Operational & Security Overhead
We deliver a fully audited, production-ready routing system. Your team avoids the 6-12 month development cycle and ongoing maintenance of in-house MEV protection logic.

Enhance Protocol Revenue & TVL
Secure, efficient routing attracts higher-volume traders and liquidity providers. Reduced MEV leakage means more value accrues to your protocol's fee treasury and stakers.

Why a Custom MEV-Resistant Router is a Strategic Advantage
Build vs. Generic Cross-Chain Solution
Comparing the total cost of ownership and strategic outcomes between developing a custom MEV-resistant router in-house, using a generic third-party bridge, and partnering with Chainscore for a tailored solution.
| Critical Factor | Build In-House | Generic Bridge / SDK | Chainscore Custom Router |
|---|---|---|---|
Time to Production | 6-12+ months | 2-4 weeks | 4-8 weeks |
Upfront Development Cost | $250K - $750K+ | $0 - $50K (integration) | $80K - $200K |
MEV Resistance & Slippage Control | Full control (if built correctly) | None - generic, public mempools | Custom logic with private RPCs & intent-based routing |
Security Posture & Audit Burden | High risk; your team manages full audit lifecycle | Shared risk; dependent on provider's security | Managed risk; includes formal audit & ongoing monitoring |
Custom Logic & Business Rules | Fully customizable | Highly limited or impossible | Tailored to your tokenomics, fee models, and UX |
Ongoing Maintenance & Upgrades | Full-stack DevOps team required | Provider-managed, but you adapt to their changes | Co-managed SLA with 24/7 monitoring and upgrade path |
Cross-Chain Liquidity Sourcing | You must build or integrate aggregators | Limited to provider's liquidity pools | Multi-source aggregation from DEXs, bridges, and market makers |
Total Cost of Ownership (Year 1) | $400K - $1M+ | $50K - $150K (fees + integration) | $120K - $300K (all-inclusive) |
Strategic Outcome | Maximum control, maximum cost & risk | Fastest launch, commoditized feature, no defensibility | Competitive moat, optimized economics, scalable foundation |

METHODOLOGY
Our Design & Implementation Process
A systematic, security-first approach to architecting and deploying MEV-resistant cross-chain routing. We deliver production-ready systems, not just theoretical designs.
01
Architecture & Threat Modeling
We begin with a comprehensive threat model, identifying potential MEV vectors (front-running, sandwich attacks) and network-level risks. This defines the security parameters for your entire routing system.

Attack Vectors Analyzed
Zero-Trust
Design Principle
02
Protocol Selection & Integration
We evaluate and integrate the optimal protocols (e.g., Chainlink CCIP, Axelar, Wormhole, LayerZero) based on your security, latency, and cost requirements for cross-chain messaging and state verification.

Relayer & Validator Design
We design a decentralized, fault-tolerant relayer network with economic security (staking/slashing) and implement commit-reveal schemes or encrypted mempools to obscure transaction intent from searchers.

Frequently Asked Questions
Get clear answers on our design process, security, and delivery for your cross-chain infrastructure.
Our process follows a structured 4-phase approach: 1) Discovery & Design (1-2 weeks): We analyze your target chains, liquidity sources, and threat models to architect the optimal solution. 2) Core Development (3-5 weeks): Our team builds the smart contracts, relayers, and off-chain logic with weekly syncs. 3) Security & Testing (2-3 weeks): We conduct internal audits, simulate MEV attacks, and perform integration testing. 4) Deployment & Handoff (1 week): We assist with mainnet deployment, provide documentation, and initiate the support period. Most projects launch in 7-11 weeks from kickoff.
