NON-CUSTODIAL MANIFESTO

Your Infrastructure. Your Wallets. Your Control.

XPay Labs returns cryptographic sovereignty to the merchant. By running a self-hosted checkout cluster, your assets route directly to address structures owned and generated solely by your node.

100% Non-Custodial

All private keys, mnemonic generation seeds, and transaction signing blocks execute locally within your isolated containers.

White-Label Freedom

Theme, branding, localized translation sequences, and notification layouts belong completely to your interface.

Flexible Unified Deployment

Run the JVM core as a secure Docker container, and deploy the entire checkout interface and indexers in one click via Docker Compose.

Zero Gateway Fees

Eliminate standard 1-2% middleman network fees. Pay strictly on-chain gas costs for network transactions.
