Frequently Asked Questions
Get clear answers on how our tax-optimized routing solution integrates, scales, and delivers value for your payment platform.
Our router is a smart contract-based middleware that sits between your payment gateway and liquidity sources. It analyzes real-time on-chain data, user jurisdiction, and asset-specific tax implications to automatically route transactions through the most cost-effective path. For each payment, it calculates the net cost (gas + fees + estimated tax liability) across multiple DEXs and bridges, selecting the route that minimizes the total settlement cost for the end-user while ensuring compliance.
