从我的智能合约中调用已部署的智能合约的功能

Question

i want to call the openTrade() function of this smart contract https://polygonscan.com/address/0xd8D177EFc926A18EE455da6F5f6A6CfCeE5F8f58#code (starts at line 371) from within my smart contract.

I have read about the ABI but this does not seem to work. What steps do i need to take ? Copy paste the whole smart contract into my visual studio code and import it into my contract?

How can i just call this specific function ?

Thank you so much guys !

Answer 1

This is the decription of the function you want to call:

  function openTrade(...) external notContract notDone { ... }

As you can see there is notContract modifier applied to this function. An this is implementation of the modifier:

modifier notContract(){ require(tx.origin == msg.sender); _; }

It means that openTrade function can not be called from the other contracts.
