Pay with Card

The primary payment currency on Only1 is USDC (Solana), a stablecoin pegged to the U.S dollar. Users can top up their Only1 wallets internally with USDC via our fiat-on-ramp partner Alchemy. Alchemy supports over +25 local currencies and various payment methods, including Credit Card (Visa/Mastercard), Google Pay, and Apple Pay, depending on the user's location.

As gasless transactions eliminate the need to top up SOL for gas fees, topping up USDC alone is sufficient to fully interact within the platform.

Advanced Web3 users can sign in via Phantom, Glow or Solflare and top up their wallets externally with USDC (Solana) from exchanges
