I just switched to solana from solidity.currently im using solang for ease of use.I know in solana there is no msg.sender but solana can detect payer of tx.I want to write a program that will send 1token per lamport to payer of tx.it means a i need a contract or program address. when a user sent 1 lamport to that he recive 1 spl-token of an already minted token.it require 4 features
- solana program be able to recive lamport
- solana program be able to detect who payed the lamport transaction
- solana program be able to detect how much lamport recived
- solana program be able to recive and send spl token
is it possible to do this in solana ?
✏️ Edit :The problem here is not finding msg.sender. i want send spl to person who paid the fee. Problem is detecting amount of lampons and sending slp
