Engineered for Tax Workflow Efficiency
Our indexer is purpose-built to eliminate the manual data wrangling and compliance risks that slow down crypto tax reporting. We deliver structured, auditable data flows directly into your existing systems.
Automated Cost Basis & Gain/Loss Calculation
We process every DeFi swap, liquidity event, and airdrop to deliver accurate, real-time cost basis and realized gain/loss data. Eliminates manual spreadsheet errors and saves hundreds of analyst hours per quarter.
Regulatory-Compliant Data Structuring
Data is normalized to IRS Form 8949, FATCA, and MiCA standards out-of-the-box. Includes wallet attribution, entity tagging, and audit trails required for financial reporting and regulatory examinations.
Enterprise-Grade Security & Data Integrity
SOC 2 Type II compliant infrastructure with end-to-end encryption. All historical data is cryptographically verified against on-chain sources, ensuring an immutable record for audits.
Business Outcomes: Faster Compliance, Lower Risk
Our tax-specific indexer is engineered to deliver measurable operational and financial advantages, turning complex blockchain data into a strategic asset for compliance teams.
Real-Time Tax Liability Calculation
Continuously monitor wallets and smart contracts to calculate capital gains, income, and VAT obligations in real-time. Eliminate month-end reconciliation delays and ensure your books are always audit-ready.
Automated Regulatory Reporting
Generate formatted reports for IRS Form 8949, FATCA, DAC8, and other global mandates directly from indexed data. Reduce manual reporting workload by over 80% and minimize human error in compliance filings.
Audit-Grade Data Integrity
Every transaction is cryptographically verified and tagged with immutable provenance. Our system provides a complete, tamper-proof audit trail that satisfies the strictest regulatory and internal audit requirements.
Proactive Risk & Anomaly Detection
Set automated alerts for unusual transaction patterns, potential wash trading, or movements involving sanctioned addresses. Mitigate compliance risks before they escalate into costly penalties or operational shutdowns.
Seamless Integration with Legacy Systems
Deploy our indexed data feeds directly into your existing ERP, accounting software (QuickBooks, NetSuite), or internal dashboards via robust APIs. Achieve full operational visibility without costly system overhauls.
Cost-Efficient Scalability
Our infrastructure scales elastically with your transaction volume, eliminating the need for large upfront capital expenditure on internal data engineering teams. Convert a fixed cost center into a variable, outcome-driven expense.
Tax-Specific Indexer vs. Generic Alternatives
Generic blockchain indexers are not designed for the complexity of tax and compliance data. This comparison highlights why a specialized solution is critical for accurate, auditable financial reporting.

Our Delivery Process: From Specification to Production
We deliver a production-ready, tax-aware blockchain indexer through a structured, milestone-driven process. This ensures clarity, reduces risk, and guarantees you receive a system that meets your exact compliance and data needs.
1. Discovery & Specification
We conduct a deep-dive workshop to map your specific tax jurisdiction requirements (e.g., FIFO, LIFO, HIFO, wash sale rules) to on-chain data. We define the exact transaction types, accounting methods, and reporting outputs you need.
2. Architecture & Design
Our engineers design a scalable, multi-chain indexer architecture. We select the optimal data models for tax logic, plan for chain reorgs, and design APIs for seamless integration with your existing accounting or reporting systems.
3. Core Development & Logic Implementation
We build the indexer's ingestion engine and implement your precise tax calculation logic. This includes handling complex DeFi events (liquidity provision, staking rewards, airdrops) and applying the agreed-upon cost-basis accounting rules.
4. Testing & Validation
We run the indexer against historical blockchain data to validate accuracy. We perform unit, integration, and stress testing, and provide a sample report for your finance team to verify calculations against manual records.
5. Staging Deployment & Integration
We deploy the indexer to your staging environment and assist your developers in integrating the APIs. We conduct end-to-end workflow testing to ensure data flows correctly into your reporting dashboards or tax software.
6. Production Launch & Ongoing Support
We manage the production deployment, configure monitoring/alerting, and provide comprehensive documentation. You receive a 99.9% uptime SLA and ongoing maintenance for protocol upgrades and new chain integrations.
Custom Blockchain Development

Frequently Asked Questions
Get clear answers on how our specialized blockchain indexer delivers accurate, audit-ready tax data for your platform.
Our service is built exclusively for tax compliance. While a standard indexer tracks transactions, ours is pre-configured to identify and categorize taxable events (swaps, staking rewards, airdrops, NFT sales) according to IRS guidelines and international frameworks. We automatically calculate cost basis, FIFO/LIFO accounting, and generate formatted reports for platforms like TurboTax or professional accountants, saving hundreds of development hours.
