This section uses the ```Goerli``` testnet environment.

#### balanceOf

Next, let's practice again how to call the ```Read``` method of a contract to read contract information, call the ```balanceOf``` method of ERC20 contract to query token balance, the balanceOf method has only one parameter, which is not named, but can be identified by its type as an address (i.e., the address of the token being queried). Since the returned data is not in units of one token, we also need the precision data of tokens for conversion. The precision of tokens can be obtained by using ```decimals``` method in ERC20 contracts. We will use Ethereum testnet ```goerli``` for testing. Please note that token contract addresses may vary on different chains.

```javascript
function toAmount(s, decimals) {
    return Number((BigDecimal(BigInt(s)) / BigDecimal(Math.pow(10, decimals))).toString())
}

function main() {
    let walletAddress = exchange.IO("address")
    
    // goerli WETH address 
    let wethAddress = "0xB4FBF271143F4FBf7B91A5ded31805e42b2208d6"
    // goerli LINK address 
    let linkAddress = "0x326C977E6efc84E512bB9C30f76E30c160eD06FB"

    // Since it is an ERC20 contract, FMZ has built-in ABI registration, so there is no need to register ERC20 ABI here.
    let wethDecimals = exchange.IO("api", wethAddress, "decimals")
    let linkDecimals = exchange.IO("api", linkAddress, "decimals")

    let wethBalance = exchange.IO("api", wethAddress, "balanceOf", walletAddress)
    let linkBalance = exchange.IO("api", linkAddress, "balanceOf", walletAddress)
    Log("WETH precision:", wethDecimals, "wethBalance:", toAmount(wethBalance, wethDecimals))
    Log("LINK precision:", linkDecimals, "linkBalance:", toAmount(linkBalance, linkDecimals))

유니스워프 V3

Uniswap V3이더리움 블록체인에 기반을 둔 분산 트랜잭션 프로토콜으로, 암호화폐 거래와 유동성 제공을 촉진하는 데 사용됩니다. 핵심 계약, 풀 계약, 공장 계약, 라우터 계약 등을 포함한 일련의 스마트 계약으로 구성됩니다.

다음 계약들은 주로 현재 환율을 검색하고 환율 거래를 수행할 때 사용된다.Uniswap:

• Router(루터 계약) 이 계약은 거래를 실행하는 데 사용되는 계약이며, 사용자가 거래 경로와 매개 변수를 지정하여 거래 거래를 수행 할 수 있습니다.
• Pool(pool 계약) 풀 계약은Uniswap특정 자산 쌍의 유동성을 저장하고 관리하기 위해. 각 자산 쌍에는 해당 풀 계약이 있으며, 이는 유동성 공급자에서 제공하는 자금, 가격 범위, 수수료 설정 등에 대한 정보를 포함합니다. 풀 계약은 거래를 처리하고 풀 상태를 계산하며 거래의 원활한 실행을 보장합니다.
• Factory(공장 계약) 공장 계약은 제조 및 관리에 사용되는 계약입니다Uniswap풀 계약. 사용자가 새로운 자산 쌍을 만들고 싶을 때, 그들은 공장 계약과 상호 작용하여 새로운 풀 계약을 배포합니다. 공장 계약은 풀 계약의 생성 및 초기화를 조정하여 사용자가 새로운 자산 쌍을 동적으로 만들 수 있습니다.

이전 강의에서 배웠듯이,ABIFMZ 양자 거래 플랫폼에서 전략 코드에서 스마트 계약의 ABI를 얻는 과정은 이전 수업에서 논의되었으며 여기에서 반복되지 않습니다. 3개Uniswap스마트 계약ABIs를 등록해야 합니다. 예를 들어 이더리움 메인넷을 이용해서요.
