How to select a gas policy strategy

This guide demonstrates the steps to create a gas policy.

What's a policy strategy?#

Gas policiy strategies are the first element to define who and how are the transactions sponsored. Openfort let's you create unlimited combination of gas policies to interact with.

There are three types of gas strategies that you can select:

  • Pay gas for user: Developers pay the gas fees on behalf of your users (users don't need to hold native tokens on their accounts).
  • Charge dynamic amount of ERC-20 tokens: Users pay gas with an ERC-20 token given an exchange rate provided by you. For example, for every 1 unite of a native token I pay with 10 unites of ERC20. Useful if you have a trading ERC20 token.
  • Charge fixed amount of ERC-20 tokens: Users pay a gas with a fix amount of ERC-20 tokens per transaction. For example, for every 1 unite of native tokens I pay 0.5 unites of ERC20. Useful if you want to offer a constant gas token price.
