Fast and secure international payments.

Accepting crypto payments

With blockchain payments, there's no sensitive customer information to collect and store and no cards to charge. Customers send stablecoins (e.g. USDT, USDC, or others) directly to a crypto address from their computer or mobile device.

We support the following ERC-20 blockchains: Ethereum, BNB Smart Chain, Polygon, Arbitrum, Optimism and Polygon zkEVM. Fanspay allows to accept payments in the following stablecoins:

Ethereum: USDT I DAI I USDC

BNB Smart Chain: USDT I BUSD I USDC

Polygon: USDT I DAI I USDC

Polygon zkEVM: USDT I DAI I USDC

Smart contracts

Fanspay uses smart contracts, that are responsible for debiting tokens from the customer's account and transferring them to your account.

Fanspay does not store your funds, funds go directly from the customer's account to yours.

Gasless payments (soon)

Gasless transactions (meta-transactions) are transactions in which the cost of gas is abstracted and paid by Fanspay and not by the customer.

Gasless transactions help provide a smoother experience for customers and allow them to make payments more easily without having to move or set aside gas tokens (e.g. ETH) manually.
