🧪 Swift Yield is an advanced Flash Loan Arbitrage bot that harnesses the power of flash loans from Balancer to perform arbitrage trading across various decentralized exchanges (DEXs) on Base Mainnet

Currently, Three Decentralised Exchanges are integrated

• ✅ Uniswap V2: Factory Contract Address, V2Router02 Contract Address can be found here

• 🧱 Sushiswap V2: Factory Contract Address, V2Router02 Contract Address can be found here

• 🧱 Pankcake Swap V2: Factory Contract Address, V2Router02 Contract Address can be found here

Based on Uniswap V2 Code/Smart Contracts there are 643 Forked Protocols. So we can integrate hundreds of DEX into this bot.

The Flash Loan Smart Contract is deployed on Tenderly's Base Mainnet Virtual Testnet.

You can access the Public Explorer from here [https://dashboard.tenderly.co/explorer/vnet/753ba0a6-023a-4c8d-b3e4-60f03d6dc4b7/transactions?kind=standard]

One more major component here is World ID

World ID is a digital identity solution that enables users to anonymize their uniqueness and humanity via zero-knowledge proofs and advanced privacy-preserving cryptography.

For Testing the app

1. Visit https://swiftyield.vercel.app/ and click on start arbitrage, verify yourself with World ID, then deploy the contract.

2. After the contract is deployed copy the contract address.

3. Clone this repo and run

yarn install

4. Then Run the bot by running this command

yarn bot 

You can use npm instead of yarn

You can then check the transaction here [https://dashboard.tenderly.co/explorer/vnet/753ba0a6-023a-4c8d-b3e4-60f03d6dc4b7/transactions?kind=standard]

Note: Some Transactions may fail because of the gas fees issue, we are optimizing the contract code

For Setting up Dev Environment

⚙️ This application is built using Scaffold Eth 2.

Requirements

Before you begin, you need to install the following tools:

• Node (>= v18.17)
• Yarn (v1 or v2+)
• Git

To get started with Swift Yield Development, follow the steps below:

1. Install Tenderly CLI

curl https://raw.githubusercontent.com/Tenderly/tenderly-cli/master/scripts/install-macos.sh | sh

2. Then login (create an account first)

tenderly login

3. Clone this repo & install dependencies

git clone https://github.com/SudeepGowda55/SwiftYield.git
cd SwiftYield
yarn install

4. To deploy the contract to tenderly:

Create packages/tenderly/.env

# https://docs.tenderly.co/account/projects/account-project-slug
TENDERLY_ACCOUNT_ID=
TENDERLY_PROJECT_ID=

# https://docs.tenderly.co/account/projects/how-to-generate-api-access-token
TENDERLY_ACCESS_TOKEN=

Create packages/hardhat/.env

ALCHEMY_API_KEY= # leave empty
# DEPLOYER_PRIVATE_KEY=
ETHERSCAN_API_KEY= # leave empty

# https://docs.tenderly.co/account/projects/account-project-slug
TENDERLY_ACCOUNT_ID=
TENDERLY_PROJECT_ID=
# https://docs.tenderly.co/account/projects/how-to-generate-api-access-token
TENDERLY_ACCESS_TOKEN=
TENDERLY_AUTOMATIC_VERIFICATIONS=true

Create a staging environment

Note: use different environment name (test-1) every time

cd packages/tenderly
yarn stage:new test-1 8453
yarn stage:activate test-1
yarn stage:connect:hardhat
yarn stage:connect:nextjs

Now deploy the contract by running

cd packages/hardhat
yarn deploy --network virtual_mainnet

Now the contract will be deployed

5. To start NextJS app:

cd packages/nextjs
yarn dev

Visit the app on: http://localhost:3000. You can tweak the app config in packages/nextjs/scaffold.config.ts.

6. Now to interact with the bot and perform Flash Loan Arbitrage run the following commands in shell:

cd packages/bot
node arbitrageBot.js
