How to pay with crypto
New to this? Don't worry. Here's exactly what happens when you pay a QBitFlow checkout — no jargon, nothing to install beyond a wallet.
Before you start
What you'll need
A crypto wallet
Any major wallet works — MetaMask, Phantom, Coinbase Wallet, and more. Prefer a hardware wallet? Ledger and OneKey work too (OneKey is open-source, like us). You'll connect it in a couple of taps; you never paste an address.
Funds on a supported network
Have the coin you want to pay with sitting in your wallet on one of our supported networks: Ethereum, Base, or Solana. The checkout shows you which coins the seller accepts.
Networks & coins
Where you can pay
A “network” is the blockchain your money travels on. Pick the one your funds are already on — you don’t need to move them around.
Ethereum
The original network. Great if your funds are already here.
Coins you can pay with
Base
An Ethereum network with lower fees. Uses ETH for gas.
Coins you can pay with
Solana
Fast and low-cost. Uses SOL for gas.
Coins you can pay with
Brand new, with no crypto yet?
Any of these work — here's a simple way to choose:
- BaseGreat default for most people — very low fees, and easy to fund straight from a Coinbase account or MetaMask.
- SolanaThe fastest and cheapest, and a good fit if you're using a wallet like Phantom or Solflare.
- EthereumBest if you already hold funds here. Fees run higher, so it's less ideal as a first choice.
Still unsure? Base or Solana are the easiest, lowest-cost places to start.
What about fees?
Paying in a stablecoin
USDC, USDT, EURC and friends — QBitFlow covers the network fee. On Ethereum or Base, the first time you use a given coin you approve it once (a tiny one-time ETH fee), then every payment after is gasless. On Solana there's no approval step at all.
Paying in a native coin
Pay in ETH or SOL and you cover a small network fee in that same coin when you approve — just like any wallet-to-wallet transfer. Keep a little ETH (Ethereum or Base) or SOL (Solana) on hand.
Network fees are set by the blockchain, not by QBitFlow, and rise a little when the network is busy.

Questions
Frequently asked
Which wallet can I use to pay?
Any major crypto wallet works — MetaMask, Phantom, Coinbase Wallet, and more. Hardware (cold) wallets like Ledger and OneKey work too. You connect your wallet in a couple of taps; you never paste an address or share your keys.
Which network should I be on?
Pick the network your funds are already on: Ethereum, Base, or Solana. The QBitFlow checkout puts you on the right network automatically, and if your wallet is elsewhere it shows a one-tap “Switch network” button before you pay.
Which token or coin do I need?
Whatever coin the seller accepts — the checkout lists them for you. Stablecoins like USDC, USDT and EURC are great for paying an exact dollar amount. You can also pay in native coins like ETH or SOL.
Do I need ETH or SOL for gas fees?
Paying in a stablecoin is gasless — QBitFlow covers the network fee. On Ethereum or Base, the first time you pay with a given coin you approve it once (a tiny one-time ETH fee), then every payment after that is gasless. On Solana there is no approval step. If you pay in a native coin (ETH or SOL), you pay a small network fee in that same coin, so keep a little on hand.
Is it safe? Does QBitFlow hold my money?
No — QBitFlow never holds your funds or sees your keys. Payments go straight from your wallet to the seller’s wallet, and the smart contracts that move the money are open-source and auditable, so anyone can inspect exactly what happens.
