EVM Staking Tax Engine Comparison
Build vs. Buy vs. Manual
Evaluating the three primary paths for obtaining a compliant, production-ready EVM staking tax engine for your DeFi protocol or exchange.
| Consideration | Build In-House | Buy (Chainscore) | Manual Processing |
|---|---|---|---|
Time to Production | 6-12+ months | 4-8 weeks | Ongoing (per tax season) |
Initial Development Cost | $200K - $500K+ | $50K - $150K | N/A |
Ongoing Annual Cost (Maintenance, Updates) | $100K - $250K | $25K - $75K (Optional SLA) | $50K - $200K (Accountant/Dev Hours) |
Coverage (Rewards, Slashing, MEV, etc.) | Custom (Risk of Gaps) | Comprehensive & Updated | Manual, Prone to Error & Omission |
Security & Audit Status | High Risk (Unaudited) | Low Risk (Formally Audited) | Operational Risk (Human Error) |
Regulatory Compliance (IRS, MiCA) | Your Liability | Our Liability (via Contract) | Your Liability |
Integration Complexity | High (Full Stack Devs Required) | Low (API/SDK) | Very High (Data Reconciliation) |
Scalability with User Growth | Requires Re-engineering | Handled Automatically | Manually Intensive, Cost Explodes |
Primary Risk | Technical Debt & Regulatory Exposure | Vendor Dependency | User Liability & Reporting Failures |

Frequently Asked Questions
Get clear, technical answers about our specialized tax calculation and reporting service for staking protocols.
Our engine ingests on-chain data from your staking contracts (deposits, withdrawals, slashing events) and off-chain data (oracle prices, validator performance). It applies configurable tax logic—FIFO, LIFO, or specific identification—to calculate cost basis, reward income, and capital gains/losses for each user, compliant with IRS guidelines and international standards. We generate detailed, audit-ready reports.
