Frequently Asked Questions
Get clear answers on our privacy-first custody layer development, from security and timelines to support and integration.
A ZK-Rollup Privacy-First Custody Layer is a specialized blockchain infrastructure that leverages Zero-Knowledge proofs to bundle and settle transactions off-chain while providing cryptographic proof of their validity on a mainnet like Ethereum. Our service builds a custom custody solution on top of this, enabling your platform to manage user assets with institutional-grade security and privacy. This means user balances and transaction histories are shielded on-chain, while you retain full, verifiable control and compliance oversight off-chain.
