• Uniswap Exchange A
• Uniswap Exchange A

---

Usage

Below are high level instructions to try out this example using the Kovan Testnet.

---

Setup

Rename env to '.env' and complete the missing values for your project.

Connect your truffle console to the Kovan network like so:

truffle console --network kovan

---

Compile / Deploy

Compile and deploy the contract to the Kovan network. From within your truffle console instance do the following:

compile
migrate --reset

---

Interact via Truffle Console

Interact with the contract via the truffle console:

let f = await FlashloanMoneyLego.deployed()
let assetToFlashLoan = '0xFf795577d9AC8bD7D90Ee22b6C1703490b6512FD' // DAI
let amountToLoan = web3.utils.toWei('1') // 1 'unit' of the 'assetToFlashLoan' (DAI)
Object.keys(f)
f.addressesProvider()
f.initateFlashLoan(assetToFlashLoan, amountToLoan)

---

Interact via Typescript app
