·         Finality in 3-5 seconds

PWC Wallet Integration

Every $PWC transaction is processed through a native PWC Wallet, seamlessly connected to the XRP Ledger.

·         Micro-payments and merchant transactions

·         Cross-border usability with ultra-low fees

Decentralized & Secure

Validators are geographically and institutionally diverse, making the network resilient and censorship-resistant, while still fast and efficient.
