Frequently Asked Questions
Get clear answers on how our secure, automated escrow smart contracts work, from development to deployment and beyond.
Our smart contracts automate the entire tax withholding and remittance lifecycle. For each transaction (e.g., a token sale or royalty payment), the contract calculates the applicable tax liability in real-time, securely escrows the funds in a dedicated, non-custodial vault, and automatically remits payment to designated tax authority wallets on a pre-defined schedule (e.g., monthly, quarterly). This removes manual calculation errors and ensures 100% compliance. We integrate with oracles for real-time rate data and provide a full audit trail on-chain.
