运行以上代码，可以查询到当前钱包的WETH、LINK代币余额：

> WETH精度： 18 wethBalance: 0
> LINK精度： 18 linkBalance: 51.41374973681053

#### deposit

可以看到这个钱包中WETH代币的余额是0，接下来我们继续和WETH代币的ERC20智能合约交互，这次我们调用Write类型的方法：```deposit```。
```deposit```方法的作用简单来说就是可以把一定量的ETH换为WETH，需要注意```deposit```方法没有参数（可以通过查看ABI观察到），该方法的属性```payable```为```true```，所以调用时需要设置转账ETH（payableAmount）数量，用来指定存入的ETH数量。

> 调用智能合约方法时注意：
> 如果调用的方法具有payable属性，需要在方法名后加一个转账ETH的值(exchange.IO函数的第四个参数)，可以是数值类型，也可以传字符串形式的数值。

이 예제에서 사용자 정의 함수를 사용했습니다.waitMined이 함수의 함수들은 사실 우리가 모르는 것들이 아닙니다.eth_getTransactionReceipt이 waitMined 사용자 정의 함수의 역할은 입력된 트랜잭션 해시의 결과를 얻기 위해 기다리는 것입니다.

이 WETH 트랜잭션에 대해 관심있는 독자들은 이 트랜잭션 해쉬에 문의할 수 있습니다.0x2fafb62b548a1fffb0f3189429e3c5a4f57ddafb0acbc0678d8b3cf0a2f7c92c이 글의 자세한 내용은 https://www.goerli.com/testing/에서 확인할 수 있습니다.

이 코드는 위와 이전 코드에 있습니다deposit이 방법의 예는 기본적으로 똑같습니다. 하지만 마지막 단계로 호출된 방법은withdraw전화하기 전에:

WETH 정확도: 18 wethBalance: 0.01 ETH 정확도: 18 ethBalance: 0.11322979983231546

다른 질문:

WETH 정확도: 18 wethBalance: 0 ETH 정확도: 18 ethBalance: 0.1231207156449464

그리고 0.01을 더하면 됩니다WETH다시 바꾸어ETH。

유니스워프 V3

Uniswap V3이 트랜잭션 프로토콜은 암호화폐의 거래와 유동성을 구현하기 위해 이더리움 블록체인에 구축된 분산 트랜잭션 프로토콜이다. 이 트랜잭션 프로토콜은 핵심 계약, 풀 계약, 공장 계약, 루팅 계약 등 다양한 종류의 스마트 계약으로 구성된다.

사용중Uniswap현재 교환 가격을 검색하거나 교환 작업을 수행 할 때 주로 다음 계약을 사용합니다.

Router(방송 계약) 이 계약은 거래를 실행하기 위해 사용되며 사용자가 거래 경로와 매개 변수를 지정하여 거래 작업을 수행 할 수 있습니다.
Pool(수수 협약) 이 협약은Uniswap특정 자산 쌍의 유동성을 저장하고 관리하는 핵심 구성 요소이다. 각 자산 쌍에는 해당 풀 계약이 있으며, 여기에는 유동성 제공자로부터 제공되는 자금, 가격 범위, 처리 요금 설정 등의 정보가 포함되어 있다. 풀 계약은 거래를 처리하고, 풀의 상태를 계산하고, 거래의 원활한 실행을 보장하는 역할을 한다.
Factory(공장 계약) 공장 계약은 창업 및 관리에 사용됩니다.Uniswap펀드 계약의 계약. 사용자가 새로운 자산 쌍을 만들고 싶을 때, 그들은 공장 계약과 상호 작용하여 새로운 펀드 계약을 배포한다. 공장 계약은 펀드 계약의 생성과 초기화를 조정하는 역할을 하며, 사용자는 새로운 자산 쌍을 동적으로 만들 수 있다.

앞서 배운 내용에 기초하여, 이제 FMZ의 양적 거래 플랫폼 전략 코드에서 스마트 계약을 등록하는 방법을 다시 살펴 보겠습니다.ABI우리는 이전 강의에서 ABI를 어떻게 얻을 수 있는지 설명했습니다. 3개 등록을 해야 합니다.Uniswap스마트 계약ABI에테리움 네트워크의 예로:

ABI에 스마트 계약을 등록한 후, 다음으로 사용에 대해 알아보겠습니다.Uniswap V3이 작업은 우리가 사용하는ERC20토큰의 교환 (이테리움에서) 은 구체적인 시나리오입니다.

질문`Uniswap V3`노선 계약 허가

이쪽에서ERC20이 모든 것은 우리가 해야 할 일입니다.allowance이 함수는 다른 주소로 허가된 토큰의 수를 검색하는 데 사용됩니다. 특정 주소가 다른 주소로 허가된 토큰의 수를 검색할 수 있습니다. (일반적으로 계약 주소는) 자신의 계좌에서 전송할 수 있습니다. 이 문제에 대해Uniswap V3로팅 계약에 대해선,approve이 함수들은 루터 계약의 주소를 부여합니다.ERC20토큰의allowance이 함수는 해당 권한의 수를 검색합니다.

그리고 우리가 지난 강의에서 보여드린 것을 기억하세요.ERC20이 모든 것은 우리가 할 수 있는 일입니다.allowance、approve모든 것이ERC20이 모든 것들은 우리가 전에 설명했던 것과 같습니다.balanceOf、transfer모든 방법은 동등한 위치에 있습니다.

그래서, 이 모든 것을 바꾸기 전에,Uniswap만약 우리가 교환하려는 동작이 다음과 같다면1INCH->ETH이 요금은 10000로 설정되어 있습니다. 이 요금은 10000으로 설정되어 있으며 1%의 요금을 나타냅니다.Uniswap이 융자 풀은 다양한 요금을 지불할 수 있습니다.Uniswap설정된 몇 가지 옵션. 예를 들어, 요금이 3000로 설정되어 0.3%로 표시됩니다.Uniswap문헌, 관련 정보.

여기 주목해야 할 것은, 실제 교환 풀은1INCH/WETH에테리움 (ETH) 와 WETH (WETH) 는 에테리움의 두 가지 다른 토큰이다.

ETH (에테리온): 에테리움 (ETH) 은 이더리움 블록 체인의 원본 암호화폐이며, 이더리움 네트워크의 주요 자산과 계산 단위이다. 이더리움 (ETH) 은 유통성과 사용성을 보편적으로 갖춘 이더리움 원본 토큰으로 거래 비용을 지불하고, 스마트 계약 상호 작용에 참여하고, 가치를 저장하는 데 사용될 수 있다.
WETH (Ethereum 패키지): WETH는 ETH를 ERC20 표준 토큰으로 포장하는 형태이다. 그것은 ETH에 대한 스마트 계약으로 ETH가 ERC20 토큰과 스마트 계약에서 원활하게 상호 작용할 수 있도록 하는 것이다. WETH는 ETH를 WETH 계약 주소로 저장하여 생성 및 획득할 수 있으며, WETH를 언제든지 ETH로 되돌릴 수 있다.

따라서, WETH는 Ethereum 스마트 컨트랙트에서 ERC20 토큰 형태로 상호 작용할 수 있는 WETH의 포장 형태이다. 전형적인 경우, 스마트 컨트랙트에서 ETH를 사용해야 할 때, ETH를 WETH로 변환하여 거래를 하거나 DeFi 동작에 참여할 수 있으며, 그리고 필요에 따라 WETH를 다시 ETH로 변환할 수 있다.
