What is PaykingOS?

PaykingOS is a real-world blockchain payment operating system designed for everyday payments.

It allows merchants and customers to send and receive USDT and USDC stablecoin payments instantly using their own wallets.

PaykingOS does not hold user funds. All payments are made directly between wallets on the blockchain.

This makes PaykingOS a true non-custodial payment system.

How PaykingOS Works

PaykingOS connects directly to your wallet and sends payments on the blockchain. There is no company wallet between sender and receiver.
