체인링크 노드로부터 어떤 사이너가 offlamp란 컨트랙트 콜을 함.

offlamp 에 콜이 들어오면 전달 받은 데이터를 해석해서 2가지 일을 함.

1. execute -> 실제 온체인 데이터 업데이트 (누구에게 토큰을 실제로 보내는 역할)
2. trailExecute & sendMessage -> 업데이트한 내용 or 전달받은 데이터를 receive하는 개발자들이 사용할 컨트랙트쪽으로 쏴주는 역할

set your private key and validator address as a env. (If you don't know where your private key is, it is in a file called validator.key. or it should also be included in the mail you received during onboarding. )

PRIVATE_KEY="PUT YOUR PRIVATE KEY HERE"

VAL_ADDRESS="PUT YOUR VALIDATOR ADDRESS HERE"

All steps are necessary.
