Lesson 13 invalid signer bug #1380
-
|
I am following the video on AAVE, and currently I am working on a function called however, whenever I specify the signer in here is my code : const { getNamedAccounts, ethers } = require("hardhat")
const { getWeth, AMOUNT } = require("../scripts/getWeth.js")
async function main() {
//protocal treats everything as an erc 20 token
//eth and native blockchian isn't erc 20 token
//the reason why we do this is becuase it makes everything easier
//wrapped erc is bascially eth but wrapped as an erc-20 token
await getWeth()
const { deployer } = await getNamedAccounts()
//now we want to interact with the aave protocol
//lending pool address provider: 0xb53c1a33016b2dc2ff3653530bff1848a515c8c5
const LendingPool = await getLendingPool()
console.log(`the lending pool contract at ${LendingPool.address}`)
//deposit !
//by looking at the deposit function in the aave github https://github.com/aave/protocol-v2/blob/master/contracts/protocol/lendingpool/LendingPool.sol
/*
IERC20(asset).safeTransferFrom(msg.sender, aToken, amount); gets money out of our wallet
so we have to approve it
let us get the weth token first
*/
const wethTokenAddress = "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2"
//approve !
//THE weth token address is where we are going to get the weth from ...
console.log(`deployer address ${deployer}`)
await approveErc20(wethTokenAddress, LendingPool.address, AMOUNT, deployer)
console.log(`depositing....`)
await LendingPool.deposit(wethTokenAddress, AMOUNT, deployer, 0)
console.log("deposited!")
//you can look at paramters on the docs.
/*
the first is the type of asset we are depositing --> which isa weth
*/
//first we need to grab all the info about a user getUserAccountData() --> where you can see health factor etc, liquidation threshold, we want to see how much we can borrow
let { totalCollateralETH, totalDebtETH, availableBorrowsETH } = getBorrowUserData(
LendingPool,
deployer
)
}
async function getBorrowUserData(lendingpool, account) {
const { totalCollateralETH, totalDebtETH, availableBorrowsETH } =
await lendingpool.getUserAccountData(account)
console.log(`you have total collateral eth of ${totalCollateralETH}`)
console.log(`you have ${totalDebtETH} in debt `)
console.log(`you have ${availableBorrowsETH} eth to borrow`)
return { totalCollateralETH, totalDebtETH, availableBorrowsETH }
}
async function approveErc20(ERC20Address, spenderAddress, amountToSpend, account) {
//the address of our erc20 token lcoation
//contract address
//spender address: contract we are going to give approval to
//account --> to do all this on
const erc20Token = await ethers.getContractAt("IERC20", ERC20Address, account)
const tx = await erc20Token.approve(spenderAddress, amountToSpend) //with the weth contract
//we can approve it taking funds out of our wallet and giving it to the lending pool!!!
await tx.wait(1)
console.log("token approved ")
}
async function getLendingPool() {
const ILendingPoolAddressProvier = await ethers.getContractAt(
"ILendingPoolAddressesProvider",
"0xb53c1a33016b2dc2ff3653530bff1848a515c8c5"
)
const lendingPoolAddress = await ILendingPoolAddressProvier.getLendingPool()
//now we want to get the lendingpool contract
//need abi and contract addresss which we have already
const contract = await ethers.getContractAt("ILendingPool", lendingPoolAddress)
//if i specify deployer. it fails, I do not know why
return contract
}
main()
.then(() => process.exit(0))
.catch((error) => {
console.error(error)
process.exit(1)
})any help is appreciated! Thank you so much! |

let { totalCollateralETH, totalDebtETH, availableBorrowsETH } = getBorrowUserData(
LendingPool,
deployer
)You forgot to add let { totalCollateralETH, totalDebtETH, availableBorrowsETH } = await getBorrowUserData(
LendingPool,
deployer
)It should be like this. |

Oh I left it intentionally so you could see the overall problem, but not to worry, I do not have any real funds in it. And I never will ! |
