Hello, everyone🖖🏼 I am trying to sell a custom ERC20 token for USDT. I have a separate smart contract for that. How can I check how many USDT tokens are sent to my smart contract?

depends liquidity x Price of token = USDT total

it’s supposed to be sold for a fixed price

i have that: uint256 public tokensForUSDT = 2;

I am working on an nft marketplace and there should custom token

so I am just testing rn

I wanna check how many usdt were sent to calculate how many tokens the user can get for that amount of USDT

kinda like that: uint256 amountToBuy = /USDT_Sent/ * tokensForUSDT;

meaning that for 1 usdt user can get 2 tokens
