Strategic Infrastructure Decision
Build vs. Buy: Custom MEV Protection vs. Generic Bridges
Comparing the total cost, risk, and time-to-market of developing a custom MEV-arbitraged cross-chain payment system in-house versus using a pre-audited, managed service.
| Key Factor | Build In-House | Generic Bridge API | Chainscore Custom Solution |
|---|---|---|---|
Time to Production | 6-12 months | 2-4 weeks | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $0 - $10K (API fees) | $50K - $150K |
MEV Protection Depth | Customizable (your risk) | Minimal / None | Advanced (Custom Searchers & Validators) |
Security Posture | High Risk (unaudited, novel code) | Medium Risk (shared, audited codebase) | Low Risk (dedicated, audited architecture) |
Cross-Chain Settlement Finality | Your implementation (<2s to 5min+) | Provider-dependent (often >5min) | Guaranteed <2 seconds |
Ongoing Maintenance & Updates | Full-time team (2-3 engineers) | Managed by provider (limited control) | Optional SLA with 24/7 monitoring |
Custom Logic for Payment Routing | Full control | Not possible | Tailored to your liquidity & fee models |
Total Cost of Ownership (Year 1) | $500K - $1.2M+ | $50K - $200K (escalating fees) | $80K - $250K (predictable) |
Competitive Advantage | Theoretical (if executed perfectly) | None (same as competitors) | Direct (unique arbitrage logic & speed) |

Frequently Asked Questions
Get clear answers on how our service secures and optimizes your cross-chain payment flows.
Our service deploys a network of proprietary arbitrage bots that monitor price discrepancies across major DEXs on chains like Ethereum, Arbitrum, and Polygon. When a user initiates a cross-chain payment, our system identifies and executes the most profitable routing path in real-time, capturing the MEV (Maximal Extractable Value) and returning a portion of the arbitrage profit to your protocol, effectively subsidizing user transaction costs.
