Automated Crypto Tax Compliance Engine for EVM Payments
Smart Contract Development
Secure, gas-optimized smart contracts built to your exact specifications.
- Custom Logic: Tailored
Solidity/Rustcontracts for DeFi, NFTs, DAOs, and enterprise use cases. - Security & Audits: Development with
OpenZeppelinstandards, followed by formal verification and third-party audit preparation. - Gas Optimization: Every contract is profiled and optimized to reduce user transaction costs by 15-40%.
- Full Lifecycle: From initial design and testing to deployment, verification, and ongoing maintenance on your chain of choice.
We deliver contracts you can trust, with a focus on security, efficiency, and long-term maintainability.
Core Components of the Compliance Engine
Our automated tax engine is built on a modular, enterprise-grade architecture designed for accuracy, reliability, and seamless integration into your existing EVM payment flows.
Real-Time Transaction Ingestion
Continuously monitors and ingests on-chain data from over 30 EVM networks. Our system classifies every transaction type—swaps, transfers, staking rewards, and NFT mints—for precise tax event identification.
Automated Cost Basis & Gain/Loss Calculation
Applies FIFO, LIFO, or HIFO accounting methods automatically. Calculates capital gains, income, and mining/staking rewards in real-time, compliant with IRS, HMRC, and other global tax frameworks.
Regulatory Rule Engine
A dynamic rules engine that adapts to jurisdictional tax laws (US, EU, UK, APAC). Automatically applies the correct treatment for DeFi, NFTs, and staking based on the latest regulatory guidance.
Enterprise-Grade Reporting API
Generate Form 8949, Schedule D, and international equivalents (e.g., HMRC SA108) via a single API call. Export raw data or formatted PDF/CSV reports for direct filing or auditor review.
Privacy-First Data Processing
Process transaction data without storing sensitive user PII on our servers. Our zero-knowledge architecture ensures compliance with GDPR and CCPA while maintaining full calculation accuracy.
Business Outcomes: Beyond Compliance
Our Automated Crypto Tax Compliance Engine for EVM Payments delivers more than just regulatory coverage. It unlocks operational efficiency, financial clarity, and strategic growth for your business.
Accelerated Financial Closing
Automate the reconciliation of millions of EVM transactions, reducing month-end financial closing from weeks to hours. Our engine provides audit-ready reports for GAAP, IFRS, and local standards.
Real-Time Treasury Visibility
Gain instant, accurate insight into your crypto tax liabilities across all EVM chains. Proactively manage cash flow and reserves with dashboards updated on every block.
Reduced Audit Risk & Cost
Eliminate manual errors with a system built on verified tax logic and immutable on-chain data. Every calculation is traceable back to the source transaction, slashing audit preparation time and fees.
Future-Proof Regulatory Agility
Our engine dynamically adapts to new tax jurisdictions and evolving regulations like DAC8 and the Crypto-Asset Reporting Framework (CARF). Stay compliant without costly re-engineering.
Enhanced Investor & Board Confidence
Provide institutional-grade financial reporting that meets the scrutiny of auditors, investors, and regulators. Demonstrate mature governance and de-risk your cap table.
Build vs. Buy vs. Manual Process
A clear comparison of the time, cost, and risk involved in managing EVM payment tax compliance through different approaches.
| Key Factor | Build In-House | Buy (Chainscore) | Manual Process |
|---|---|---|---|
Time to Initial Deployment | 6-12+ months | 2-4 weeks | N/A |
Upfront Development Cost | $250K - $500K+ | $0 (API) | $0 |
Ongoing Engineering & Maintenance | 2-3 FTE Engineers | Fully Managed | 1-2 FTE Accountants |
Coverage: EVM Chains & Tokens | Requires constant updates | 30+ chains, auto-synced | Error-prone manual entry |
Audit-Ready Reporting | Custom build required | Pre-built forms (8949, etc.) | Manual spreadsheet compilation |
Real-Time Liability Calculation | Complex to implement | Real-time API | End-of-quarter estimates |
Security & Data Integrity Risk | High (custom code) | Low (audited, SOC 2) | Very High (human error) |
Scalability with Transaction Volume | Architecture challenge | Built for scale | Impossible at scale |
Total Cost (First Year) | $500K - $750K+ | $25K - $100K | $150K - $300K+ (labor/errors) |
Guaranteed Accuracy & Support | Your responsibility | SLA & expert support | No guarantees |
Our Delivery Methodology
We deliver a production-ready tax compliance engine in weeks, not months, using our battle-tested process designed for EVM complexity.
Discovery & Integration Audit
We analyze your existing payment flows and wallet infrastructure to map all taxable events. We identify data gaps and define the precise integration scope for a seamless deployment.
Custom Rule Engine Configuration
Our team configures the compliance engine to your specific jurisdiction (US, EU, APAC) and token types (ERC-20, NFTs, DeFi rewards). Rules are based on live tax code APIs from providers like CoinTracker.
Secure Data Pipeline Deployment
We deploy a secure, read-only node listener and data pipeline to your infrastructure. All data is encrypted in transit and at rest, with no private key exposure required.
Staging & Validation Sprint
We run the engine against your historical transaction data in a staging environment. You receive sample tax reports (Form 8949, Capital Gains) for validation before go-live.
Production Launch & Monitoring
We manage the production cutover and provide 24/7 monitoring dashboards for data health and calculation accuracy. Includes automatic alerts for any reconciliation issues.
Ongoing Compliance Updates
We handle all tax logic updates for new regulations, token listings, and protocol upgrades. Your engine stays compliant without requiring engineering resources.
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that form the foundation of your Web3 product. Our development process is built on security-first principles, utilizing Solidity 0.8+, OpenZeppelin libraries, and comprehensive audit patterns to mitigate risks before deployment.
From tokenization to complex DeFi logic, we deliver contracts that are gas-optimized, upgradeable, and built for your specific regulatory environment.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155implementations with minting, vesting, and governance modules. - DeFi Protocols: Automated Market Makers (AMMs), staking pools, yield aggregators, and lending/borrowing logic.
- Enterprise Logic: Multi-signature wallets, asset tokenization platforms, and compliant KYC/AML integration hooks.
- Full Audit Trail: Every contract undergoes internal review and is prepared for third-party audits from firms like CertiK or Quantstamp.
