[개발] 바이낸스 api 를 이용한 출금시 코인별 network 확인 방법

안녕하세요 @realmankwon 입니다.

바이낸스 api 를 이용하여 출금을 하려고 할때 코인별 network를 설정하는 것이 중요합니다.
출금할 코인이 지원하는 네트워크를 확인해야 하는데 이때 사용하는 것이 capitalConfig() 함수입니다.

아래와 같이 symbol 변수에 원하는 코인을 입력하면 networkList 에서 지원하는 network 를 확인할 수 있습니다.

const client = Binance({
      apiKey: apiKey,
      apiSecret: apiSecret,
      getTime: () => Date.now(),
    });

    let result = await client.capitalConfigs();
    result = result.filter((data) => data.coin === `${symbol}`);
    console.log(result[0].networkList);

BNB의 경우 결과값은 다음과 같습니다.
