The PayCoin Wallet is an official mobile and web app that lets users store, convert, and spend PCI and other crypto assets. It also links directly to the PayProtocol Card for in-store and online payments.

The PayProtocol Card is a Mastercard-branded crypto card that enables users to spend PCI at any merchant accepting Mastercard. Transactions settle instantly on-chain, while the merchant receives fiat payments.

Yes. PayProtocol supports multi-currency payments, including Bitcoin, Ethereum, and stablecoins. Users can select their preferred asset for payments, while merchants receive funds in their chosen crypto or fiat.

PCI is used for transactions, validator voting, and accessing ecosystem incentives. A portion of the supply funds user rewards and merchant promotions, helping grow the platform organically.

PayProtocol employs two-factor authentication, biometric access, PCI-DSS compliance, and non-custodial private key storage. Users can also manage card settings, lock/unlock features, and monitor transactions in real time.

Download the PayCoin Wallet app, complete the identity check (KYC), and link a supported exchange wallet like Korbit or Coinone via WalletConnect. Then you can top up PCI and start spending through the app or PayProtocol Card.

PCI is listed on major centralized exchanges including Bitget, Coinone, Korbit, Bithumb, and HTX. Trading pairs are typically offered in USDT or KRW.
