How to pay
Purchases are paid in USDC or USDT — dollars that live on a blockchain — sent straight to us. Never done it? It takes about five minutes the first time. Pick your region below.
Click Buy first. Your payment page gives the amount and the address to pay, and keeps them for one hour.
What we receive must match the amount on your payment page. If your app takes its fee from what you send, add the fee on top.
Only USDC or USDT, only on a network listed on your payment page: Polygon, Base, Arbitrum One or BNB Smart Chain.
Once the transfer is confirmed, your purchase is delivered by itself and your payment page turns green.
Coinbase is available across Europe: buy USDC with a card or SEPA transfer and send it on Base, where sending costs a few cents at most.
Kraken and Binance work the same way. Revolut can send USDC too, but charges a flat fee of about €3.60 per transfer whatever the network — only worth it for a large purchase.
Coinbase is the simplest way in the US: buy USDC with a debit card and send it on Base, where fees are tiny.
Kraken works the same way. PayPal, Venmo and Cash App cannot send USDC or USDT on the networks we accept.
Binance is available in most of Asia and sends USDT on BNB Smart Chain for a fraction of a dollar.
OKX and Bybit work the same way: what matters is the amount received, the token and the network.
Sent the wrong amount, or paid after the hour? Nothing is lost: it still reaches us. Open a ticket on Discord with your order number and the transaction link, and we will match it by hand. The only thing that cannot be recovered is a token sent on a network we do not accept.
