是否要把换币的服务放到我们前端

或者说帮用户适配？

类似于一键换成ycrv

基于上面的配置文件

poolAddress 是分红代币的地址
erc20address 是需要存入代币的地址

方法

读的数据

当前拥有分红代币的余额方法是

let erc20Contract = new web3.eth.Contract(config.erc20ABI, poolAddress)
var balance = await erc20Contract.methods.balanceOf(account.address).call({ from: account.address });
balance = parseFloat(balance)/10**asset.decimals

当前拥有存入代币的余额

let erc20Contract = new web3.eth.Contract(config.erc20ABI, erc20address)
var balance = await erc20Contract.methods.balanceOf(account.address).call({ from: account.address });
balance = parseFloat(balance)/10**asset.decimals

deposit 金额

let vaultContract = new web3.eth.Contract(vaultContractABI,vaultContractAddress)

var deposit_data = await vaultContract.methods.plyr_(account.address).call({ from: account.address });
var deposit = deposit_data["stake"]/1e18

eared金额

let vaultContract = new web3.eth.Contract(vaultContractABI,vaultContractAddress)
let eared = await vaultContract.methods.cal_out(account.address).call({ from: account.address });
eared = eared/1e18

pending金额

需要先读到
let data = vaultContract.methods.global_(0)..call({ from: account.address });
total_stake = data["total_stake"]
earnings_per_share = data['earnings_per_share']
var plyr_data = await vaultContract.methods.plyr_(account.address).call({ from: account.address });

var payout = plyr_data["payout"]
magnitude = 10**40

然后还需要用下面 yield查询里面的数值（假设为yield_value

earnings_per_share = earnings_per_share+yield_value*(magnitude)/(total_stake)

earnings_per_share*他质押的金额（也就是上面的deposit,没有除以1e18的值）/magnitude - payout

这个结果就是pending的金额,需要除以1e18显示给用户看.

操作

deposit:

deposit之前需要授权金额大于他 deposit的金额

检查授权金额为

let erc20Contract = new web3.eth.Contract(config.erc20ABI, erc20address)

let approve_balance = await vaultContract.methods.allowance(account.address,vaultContractAddress).call({ from: account.address });

如果授权金额小于存入金额，则授权

        await erc20Contract.methods.approve(vaultContractAddress, web3.utils.toWei('79228162514', "ether")).send({ from: account.address, gasPrice: web3.utils.toWei(await this._getGasPrice(), 'gwei') })

授权结束后再是deposit操作

deposit 操作的方法是 vaultContractAddress 的deposit ,参数是存入的金额,存入的金额需要小于他的余额

claim

操作的方法是 vaultContractAddress 的claim ,无参数

withdraw

操作的方法是 vaultContractAddress 的withdraw ,参数是他要取出的金额，需要小于他存入的最大金额
