DELIVERABLES
Engineering and Business Outcomes
Our Layer 2 Withdrawal Safety Checker delivers concrete technical results that translate directly into business value, ensuring your cross-chain operations are secure, reliable, and cost-effective.
01
Real-Time Risk Assessment Engine
Continuous monitoring of withdrawal proofs and bridge states to detect anomalies like invalid Merkle proofs or reorgs before funds are released. Prevents irreversible losses by flagging high-risk transactions for manual review.

Risk Alert Latency
24/7
Monitoring
02
Automated Proof Verification
Programmatic validation of ZK proofs, fraud proofs, and Merkle inclusion proofs against the latest L1 state. Eliminates manual review for standard withdrawals, reducing operational overhead and accelerating finality.

A Cost-Benefit Analysis for Technical Leaders
Build vs. Buy: Withdrawal Safety Monitoring
Compare the total cost of ownership, risk, and time investment between developing a custom withdrawal safety solution in-house versus using Chainscore's enterprise-grade monitoring service.
| Critical Factor | Build In-House | Buy with Chainscore |
|---|---|---|
Time to Production | 6-12 months | 2-4 weeks |
Initial Development Cost | $150K - $400K+ | $25K - $75K |
Annual Maintenance Cost | $80K - $200K (2-3 engineers) | $15K - $50K (SLA) |
Security & Audit Overhead | High (Requires external audit + internal review) | Low (Pre-audited, battle-tested system) |
Coverage: L2s & Bridges | Limited to selected chains | Ethereum, Arbitrum, Optimism, Base, zkSync, Polygon, 10+ more |
Monitoring & Alerting | Custom-built dashboards (weeks of dev) | Real-time dashboard, PagerDuty/Slack alerts |
Expertise Required | Deep L1/L2 consensus, fraud proof, MEV knowledge | Managed service, API integration only |
Uptime & Reliability SLA | Your team's responsibility (potential 99% or less) | 99.9% Guaranteed SLA with penalties |
Response to Protocol Upgrades | Manual tracking & implementation delays | Automated tracking, proactive updates included |
Total Cost of Ownership (Year 1) | $230K - $600K+ | $40K - $125K |
