overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by expert Solidity engineers.

We architect and deploy audit-ready smart contracts on Ethereum, Polygon, and other EVM chains. Our process ensures zero critical vulnerabilities before mainnet launch, protecting your assets and reputation.

  • Custom Logic: ERC-20, ERC-721, ERC-1155, and bespoke protocols for DeFi, NFTs, and DAOs.
  • Security-First: Built with OpenZeppelin standards and tested with Hardhat/Foundry.
  • Full Lifecycle: From design and development to deployment, verification, and monitoring.

Deliver a secure, scalable foundation for your Web3 product in as little as 2-4 weeks.

Why a Purpose-Built Solution Matters

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.

TRANSPARENT & PREDICTABLE

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.

01

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.

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.
