Do you really want to burn some ETH?

Sending it to 0x0000000000000000000000000000000000000000 or 0x000000000000000000000000000000000000dEaD is a popular choice, but the ETH is not really burned. There is technically a private key with access to the funds, its just that no one knows it (probably).

Of course, there is practically 0 chance of anyone ever finding the private key to these addresses, but if some does... it's a lot of ETH to dump on the market.

With Burn4Ever, ETH is really burned, forever :)

A self destructing contract can send the remaining ETH in the contract to any address. Specifically, to itself. ETH sent to the contract this way is truly burned and has no way to be restored (well maybe via a fork).

Thanks to CREATE2 and ERC-2470 we can have a constant contract address, that anyone can deploy a contract to. The contract has a single instruction: Burn all the ETH in the balance.

If there is ETH in the contract, once it is initiated, the ETH will be burned.

To compensate the burner, 0.1% of the ETH in the contract will be sent to the burner (Yay MEV!)

The contract will always be on the same address on all chains that support ERC-2470.

The library shows an example and a code snippet to deploy the contract.

Before running any command, make sure to install dependencies:

$ yarn install

Compile the smart contracts with Hardhat:

$ yarn compile

Run the Mocha tests:

$ yarn test

Polupate the .env file as seen in the example file .env.example
