Technical & Operational Details
Frequently Asked Questions on Automated Tax Withholding
Get clear, technical answers on how our automated reward tax withholding tool integrates with your protocol, ensures compliance, and scales with your operations.
Our solution integrates via a modular smart contract layer that sits between your reward distribution logic and user wallets. We deploy a proxy contract that intercepts reward payouts, calculates the withholding amount based on configurable rules (jurisdiction, user status, reward type), and automatically routes funds to designated treasury or escrow addresses. Integration typically requires updating the reward destination address in your core contracts. We provide comprehensive SDKs and documentation for Solidity, Rust (Solana), and Vyper-based systems.
