Practical overview
When it fits
Use the repository when you want to inspect or configure a JavaScript MEV bot for Ethereum or BNB Chain and can manage wallet credentials, network endpoints, and gas requirements.
Who it is for
- Developers exploring or adapting MEV arbitrage bot code.
- Blockchain users seeking a configurable trading-bot codebase for Ethereum or BNB Chain.
Documented uses
- Prepare chain-specific RPC, wallet, and trading settings for an MEV bot.
- Explore a codebase presented for DEX arbitrage and flashloan trading.
Requirements & limits
The project is presented as a public GitHub repository. Its README lists Node.js v16 or later and npm as setup prerequisites.
- The repository describes Ethereum and BNB Chain support with separate network configuration examples.
- Setup requires RPC connectivity, wallet configuration, and native tokens for gas.
- The README presents flashloan smart contracts but does not eliminate the listed gas requirements.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Prepare chain-specific configuration
Set up the documented environment variables for Ethereum or BNB Chain.
Before you start
- Node.js v16 or later and npm
- A wallet and native tokens for network gas
- An RPC endpoint or API key for the selected chain
- Basic blockchain and DeFi familiarity
Steps
Clone the repository and enter its directory.
Install dependencies with npm install.
Copy .env.example to .env and edit the environment file.
Set CHAIN to ethereum or bnb, then fill in that network's RPC and WebSocket settings, wallet values, and trading parameters.
Expected outcome
An environment file populated with the selected chain's documented connection and trading settings.
Guide limitations
- The README's configuration guidance does not establish that the bot will execute successfully or produce profitable trades.
- Wallet private keys are sensitive credentials; the README's example requires configuring one.
