아이콘 스마트컨트렉 분석(dice_roll)

출처 : https://medium.com/@2infiniti/icon-dapp-from-a-z-part-3-icon-dice-roll-dapp-7f0ca72057f5

 

준비물 : 지갑2개(키스토어),  x윈도우 웹브라우저

 

아이콘 도커 접속

docker run -it -p 127.0.0.1:9000:9000 -p 127.0.0.1:5000:5000 --rm ibriz/icon-workshop:latest

 

icon-dice-roll소스를 다운로드 받아 준다.

git clone https://gitlab.com/ibriz/icon-dice-roll.git

 

중요

tbears의 -k 키스토어 옵션과 -c 컨피그옵션은 deploy할 디렉토리와 동일하게 둔다.

tbears_cli_config.json

{     "uri": "https://bicon.net.solidwallet.io/api/v3",     "nid": "0x3",     "keyStore": null,     "from": "hx040fe47c7a7827684aa4c0bfcfdbbbdbb3ec3b6a",     "to": "cx0000000000000000000000000000000000000000",     "deploy": {         "stepLimit": "0x59682f00",         "mode": "install",         "scoreParams": {}     },     "txresult": {},     "transfer": {         "stepLimit": "0xf4240"     } }

uri : 테스트넷 서버주소

from : A지갑주소 (도박을 만든 포주)

stepLimit : ICX 스마트컨트렉 수수료

            ( 16진수로 되어 있는데 약 11 ICX정도 지출된다)

 

 

ICONex 에서 생성한 키스토어를 넣어 준다.  도박장 주인

keystore_test1

 

 

icon-dice-roll에 tbears_cli_config.json , keystore_test1  복사 한다.

저 부분이 컨트렉 주소다.

유저가 입금하고 송금 받는곳이다.

자동으로 해준다.

수수료부분만과 to만 컨트렉주소로 바꾸어 준다.

from 키스토어를 로드 할때 그 주소가 들어 가는거 같다.

백그라운드로 & 실행 시킨다. 해당 커멘드로 베팅도 해야 되기 때문이다.

1.json 유저 키스토어를 넣는다.
