</div>

function exchangeKctPos(address tokenA, uint amountA, address tokenB, uint amountB, address[] calldata path) external;

이 함수를 실행시키고나면 스왑이 되는데 스왑이 얼마만큼 된건지 Amount를 받고싶은데 혹시 없을까요?

function call 전 후로 tokenA, tokenB balance를 찍어보시면 되지 않을까요 ㅎㅎ

트랜잭션 정보를 찍어보시면 그안에 나옵니다.

Pos니까 TokenA는 입력하신 amount만큼 swap이 됐을겁니다.  
TokenB는 tx를 확인해도 좋고 전후로 balance를 확인해도 좋습니다.
