overview
FROM PROTOCOL TO PRODUCTION
Custom Blockchain Development
Build secure, scalable, and purpose-built blockchain networks for your enterprise.
- Full-Stack Architecture: From consensus mechanisms (
PoA,PoS) and RPC nodes to block explorers and wallets. - Enterprise Integration: Seamless APIs and bridges for connecting with existing systems and public networks like Ethereum and Polygon.
- Security-First: Built with audited libraries and undergoes rigorous penetration testing before launch.
Move beyond generic solutions. A custom chain gives you control over transaction costs, privacy, governance, and performance, eliminating the constraints of shared public networks.

PROVEN PROCESS
Our Delivery Methodology
We deliver a production-ready verification system through a structured, transparent process designed for compliance and security. Our phased approach ensures predictable timelines and zero surprises.
01
Discovery & Compliance Blueprint
We conduct a deep-dive analysis of your donation flow and tokenomics to map all tax-relevant events. The output is a detailed technical specification and compliance matrix for your target jurisdictions (US, EU, etc.).

Frequently Asked Questions
Get clear answers on how our system verifies crypto donations for tax compliance, ensuring your charity or platform meets IRS and global standards.
Our system integrates directly with major on-chain and off-chain data sources to establish an IRS-compliant valuation. We pull price data from multiple, vetted oracles at the exact block height of the transaction, calculate the average, and apply the appropriate valuation method (e.g., first-in-first-out, specific identification as selected by the donor). The final report includes a complete audit trail of the data sources and calculations used for each verified donation.
