refuel

⛽ Don't let your account run out of fuel

Warning

This is my sandbox project to try out Gelato (and Uniswap v3, along the way). Don't take it seriously.

How it works

The Problem

It's always sad when your native network token balance runs out, and you can't send any transaction anymore. You do have some assets in non-native tokens but still can't exchange them because you don't have enough amount of the native token to pay for the gas!

So, you need to top up your balance through a bridge with another network or, even worse, use a fiat gateway!

🤯 🤯 🤯

The Solution

With refuel you won't have to worry about your balance anymore! When the balance is about to run out, refuel will replenish it by swapping the required amount of the token of your choice.

Okay, but what's going on exactly?

• User selects
  • the source token
  • the watched token
  • the threshold
  • the amount to replenish
  • the maximum amount of the source token to spend
• refuel submits a gelato task
• The task executes a uniswap v3 swap if the balance of the watched token gets less than the threshold

Note Conditions of the task's execution are resolved by the RefuelResolver contract.

Note Swap is provided by the Refuel contract. Gelato automation contract is the only who allowed to exec its execute method.

User can see all their active tasks. For more actions like pausing / restarting tasks, it's always an option to go to the Gelato Automate app since all the tasks in refuel are mined directly by the user.

Deployments

refuel is deployed only on Goerli Testnet now. The swap implementation is very basic and follows the Uniswap tutorial closely, so it's not production-ready.

But you can pick up the idea if you like 😉
