# Solution: Gas-free Kadena, through the novel concept of gas stations, offers the ability to specify a gas payer for smart contract interactions. This allows eckoDEX to subsidize all gas fees while interacting with our DEX. That’s right, gas free, forever, whether you are adding or removing liquidity or swapping. No longer will users be required to have a separate token to pay gas or even consider gas costs when using the DEX. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
