What is BlankFX?

BlankFX lets businesses get paid in any stablecoin and settle in the one they want. Payments, conversions and liquidity run on smart contracts on Ethereum, priced against live FX oracles, with every movement traceable on-chain.

​
What it does

  • Accept payments in any listed stablecoin through payment links, a point-of-sale till or the API.
  • Convert between stablecoins of the same currency (e.g. USDC ↔ USDT) or across currencies (e.g. USDC ↔ EURC), atomically.
  • Supply liquidity to a currency pool and earn a share of the trading fees.
  • Trade by RFQ: request firm quotes from market makers for larger cross-currency tickets.
Funds never sit with BlankFX. Every value movement is signed by the user’s own wallet.

​
Who it’s for

  • Payment platforms and invoicing companies that want to accept every major stablecoin and settle in one.
  • Merchants taking stablecoin payments in store or online.
  • Market makers quoting cross-currency flow over RFQ. See RFQ for market makers.
  • Stablecoin issuers listing a coin. See How the exchange works and listing requirements.
