Charge gas fees with ERC20s to min an NFT

Learn how to charge an amount of ERC20 tokens to pay for gas fees.

Openfort support two types of use cases when paying gas with ERC20s:

  1. Dynamic: Charging (any) ERC-20 tokens you want as a form of payment for transactions (also supports stablecoins like USDC).
  2. Static: Another interesting option Openfort powers is charging in-game (ERC20) tokens as a form of payment for transactions (ideal if you want to show your users a fix amount per gas no matter the real gas fee).
