Self-Custody Payments: Users Sign, Funds Stay Secured

Self-Custody Payments: Users Sign, Funds Stay Secured

Self-custody is NAKA's core principle. For the first time, a payment system enforces real-time, on-chain signatures for every transaction. No custodial wallets. Complete user control, global acceptance.

NAKA provides the stablecoin-native infrastructure stack that makes payments programmable, instant, and universally accepted.

What True Self-Custody Means

With NAKA, every single transaction requires a cryptographic signature from the user’s private key, stored securely

inside the application environment.

User Trust

In markets where institutions freeze accounts, delay withdrawals, or block crypto operations, users prefer direct control over their own funds today.

Security

If a custodial provider is breached, user funds can be drained; with NAKA, no attacker can spend without the user’s
key signature.
