We architect and build custom blockchain solutions from the ground up. Our full-cycle development delivers production-ready systems, not just proof-of-concepts.
Cross-Chain Tax Ledger Aggregation
Custom Blockchain Development
End-to-end development of secure, scalable blockchain networks and applications tailored to your business logic.
- Layer 1 & 2 Networks: Design and deploy private, consortium, or public chains using
Substrate,Cosmos SDK, orOP Stack. - Smart Contract Systems: Develop and audit complex business logic in
Solidity,Rust (Solana), orMove (Aptos/Sui). - Full-Stack dApps: Integrate custom frontends, backends, and oracles for a complete user experience.
- Guaranteed Outcomes: We commit to specific SLAs for throughput (TPS) and finality, with 99.9% uptime for core infrastructure.
Move from concept to a live, secure mainnet deployment in as little as 8-12 weeks, backed by our team of protocol engineers.
Core Capabilities of Our Tax Ledger
Our ledger is built as a foundational data layer, providing the accuracy, security, and automation required for enterprise-grade tax and financial reporting across any blockchain.
Unified Transaction Aggregation
Automatically ingest, normalize, and reconcile transaction data from 50+ blockchains, Layer 2s, and DeFi protocols into a single, consistent data model. Eliminates manual data entry and reconciliation errors.
Cost Basis & FIFO/LIFO Accounting
Automated calculation of capital gains and losses using FIFO, LIFO, HIFO, or specific identification methods. Handles complex events like airdrops, staking rewards, and token migrations with precise cost attribution.
Real-Time Tax Liability Dashboard
Monitor estimated tax obligations in fiat currency across all holdings and jurisdictions. Scenario modeling allows for proactive tax planning before executing large transactions.
Enterprise-Grade Security & Audit
SOC 2 Type II compliant infrastructure with end-to-end encryption. Every data point is cryptographically verifiable back to on-chain source, creating an immutable audit trail for regulators and auditors.
Automated Report Generation
Generate IRS Form 8949, Schedule D, and international equivalents (e.g., HMRC, ATO) with one click. Reports are formatted for direct submission or integration with professional tax software.
DeFi-Specific Event Parsing
Accurately categorize and value complex DeFi interactions: liquidity pool transactions (add/remove), yield farming rewards, loan interest, and liquidations for precise income and gain/loss reporting.
Business Outcomes for Your Neobank
Our cross-chain tax ledger aggregation platform delivers measurable improvements to your compliance, operations, and customer experience.
Automated Multi-Chain Tax Reporting
Generate comprehensive, audit-ready tax reports (FIFO, LIFO, HIFO) across 20+ blockchains. Eliminate manual data reconciliation and reduce compliance overhead by 80%.
Real-Time Portfolio & Cost Basis
Provide customers with a unified, real-time view of their cross-chain portfolio value and cost basis. Integrates with your existing dashboards via our REST API.
Regulatory Compliance & Audit Trail
Maintain an immutable, verifiable ledger of all transactions for IRS Form 8949, MiCA, and other global regulations. All data is cryptographically signed and timestamped.
Reduced Engineering & Operational Costs
Replace the need to build and maintain complex parsers for dozens of blockchains. Our managed service cuts infrastructure costs and accelerates feature development.
Build vs. Buy: Tax Ledger Development
A detailed comparison of the total cost, risk, and time investment required to develop a cross-chain tax ledger in-house versus partnering with Chainscore.
| Factor | Build In-House | Chainscore |
|---|---|---|
Time to Market | 6-12 months | 4-8 weeks |
Initial Development Cost | $150K - $400K+ | $50K - $150K |
Annual Maintenance & DevOps | $100K - $250K | Optional SLA from $30K/year |
Security & Audit Overhead | High (unaudited, custom code) | Low (pre-audited modules, battle-tested) |
Cross-Chain Data Normalization | Build from scratch (high complexity) | Pre-built adapters for 20+ chains |
Regulatory Compliance (FIFO, LIFO, etc.) | Requires specialist hire | Built-in, configurable rule engine |
Team Requirements | 3-5 Senior Blockchain Devs + QA | Your Product Manager + Our Team |
Integration Risk | High (untested, custom APIs) | Low (standardized REST/GraphQL APIs) |
Total Cost of Ownership (Year 1) | $250K - $650K+ | $80K - $180K |
Our Delivery Methodology
We deliver production-ready cross-chain tax ledger systems through a structured, transparent process designed for financial compliance and technical reliability.
Discovery & Architecture Design
We analyze your multi-chain transaction footprint and compliance requirements to architect a scalable data aggregation model. This phase defines the source chains, data schemas, and reconciliation logic.
Secure Data Pipeline Development
We build resilient indexers and oracles to extract, normalize, and validate transaction data from EVM, Solana, and Cosmos-based networks with cryptographic proof of integrity.
Tax Logic & Compliance Engine
Implementation of jurisdiction-specific tax rules (FIFO, LIFO, HIFO) and automated cost-basis calculations. The engine produces audit-ready reports formatted for global regulators.
Deployment & Continuous Monitoring
We deploy the aggregated ledger to your secure environment with full observability dashboards. Our team provides 24/7 monitoring for data completeness and system health.
Frequently Asked Questions

Our system uses a multi-layered approach: first, we deploy custom indexers for each supported chain (Ethereum, Solana, Polygon, etc.) to extract raw transaction data. This data is then normalized into a standardized schema, reconciling differences in transaction types, token standards, and fee structures. Finally, we apply our proprietary classification engine to tag transactions (e.g., swap, staking reward, NFT purchase) and calculate cost basis using FIFO or specific identification methods. The result is a single, auditable ledger ready for tax reporting.
