MegaETH Airdrop: guide how to participate and claim
MegaETH is another L2 solution built on the Ethereum blockchain. The airdrop of this project is not officially confirmed, but it may happen at some point. At the moment, users can interact with the test network.
Testnet
Go to the page testnet.megaeth.com, then request test tokens on the Faucet button and add the test network itself to your wallet (the add button is at the bottom of the site, you need to scroll through a few blocks)

After that, you can start interacting with protocols from the list of ecosystem projects, such as GTE, AWE, and others. At this stage, the activity does not require investment, but does not guarantee an airdrop, and test tokens can be requested every 24 hours.
