What is an Account NFT and why is it needed?
The Account NFT is a unique Web3 token issued by Fiat24 that represents your personal bank account. It replaces traditional IDs and passwords by using Web3 wallet-based authentication. It is required in order to use the Paycoin Mastercard. Only one Account NFT can be issued per wallet, and duplicate issuance is not allowed for the same wallet.
How to Top-Up the Paycoin Mastercard
When Paycoin (PCI) is topped up to the card, it is automatically converted into stablecoins (USD24, CHF24, or EUR24), which are then issued to the user’s wallet. During card payments, the corresponding stablecoin balance is automatically deducted.
How is PCI converted into USD?
When a user initiates a Top-Up, PCI is automatically swapped to USDC via Uniswap, and then converted into one of Fiat24’s 24Tokens (USD24, EUR24, or CHF24).
The Top-Up process proceeds as follows:
The user initiates a Top-Up request to Fiat24
PCI is sent to a Uniswap liquidity pool and automatically swapped to USDC
The swapped USDC is converted into one of the 24Tokens (USD24, EUR24, or CHF24)
The corresponding 24Token is deposited into the user’s PayProtocol Wallet account
※ 24Tokens are stablecoins pegged 1:1 to their respective fiat currencies
