What is Ethernaut?

An open source CTF (Capture the Flag) for Solidity and web3. Each of the 26 levels are Smart Contracts that need to be "hacked".

So why did this transaction have a MetaMask pop up and why is this the only function interaction that has been registered on Etherscan. To understand it better let us look at "stateMutability" witin the ABI (https://t.co/isL1Dm1E3E)

[30/236] On entering this with authenticate function, the Metamask window pops up.

Notice that the transaction is interacting with a contract ending in "4152" which is the Instance Address in my case.

This can also be seen on Rinkeby.
