Objective: Build a Solana smart contract / program that can can create new mint token accounts and mint tokens to a PDA so users can request tokens for testing on devNet and testNet deployments.
Purpose: During the development and testing of defi protocols it is a common practice to use a faucet to get access to test tokens. This faucet will enable users/developers (and a possible frontend at a later date) to create new SPL-token's and store the minted tokens in a PDA that can then get released to users/testers when they require them for testing.
Create a permissionless init_mint_and_vault(amount_to_mint: u64) instruction that initializes a new SPL-token and mints the given number of tokens to a PDA address for later release via the request_tokens instruction.
Have a way to limit the number of times the init_mint_and_vault(...) instruction can be called from a single user, ie a single user's wallet can only call this twice forever.
Create a request_tokens instruction that will transfer tokens from the PDA to the requesting users wallet with a predefined number of tokens.
Create the instruction so a user's wallet can only call this instruction once per day.
