Code for how we can start a flash loan. Note we won't be actually doing an arbitrage here, because finding profitable arbitrage opportunities is the hardest part and not related to the code, but will essentially just learn how to execute a flash loan.

.delegatecall() is heavily used within proxy (upgradeable) contracts. Since smart contracts are not upgradeable by default. But, since it modifies the storage of the contract calling the function, there are some nasty attacks that can be designed if it is not properly implemented. We will now simulate an attack

My notes on Rust
A Whitelist Dapp using merkle tree to verify users, we are not storing the address of each user in the contract, we are only storing the root of the merkle tree which gets initialized in the constructor.
Meta transactions are just a fancy word for transactions where a third party (a relayer) pays the gas for the transaction on behalf of the user. The user just needs to sign messages (and not send a transaction) that contain information about the transaction they want to execute and hand it to the relayer. Relayers are then responsible for creating valid transactions using this data and paying for gas themselves.
This code is just meant to show you how you use Flashbots to send transactions in the first place.
