How Fizen works
Fizen Super App combines a non-custodial crypto wallet with real-world payment tools — all in one mobile app. Your crypto is stored in a blockchain wallet that only you control. You use it to pay for things directly: scan a QR code at a local shop, top up your Visa card, buy an eSIM, send money to a friend.Your wallet
Fizen uses a non-custodial wallet — meaning only you hold your private key. Fizen cannot access, freeze, or hold your funds. When you set up the app, you receive a private key. Keep it safe — it’s the only way to recover your wallet if you lose access.How crypto transactions work
Unlike bank transfers that go through a central database, crypto transactions are recorded on a distributed blockchain network — thousands of computers that all verify and store the same record simultaneously. This makes transactions:- Transparent — anyone can verify on-chain
- Secure — no single point of failure
- Irreversible — once confirmed, they cannot be undone
Supported networks
Fizen supports multiple blockchain networks. For Fizen Card top-ups, use Solana (lowest fees, fastest confirmation).Always make sure you’re sending on the correct network. Sending USDT on the wrong network may result in permanent loss of funds.
