This project shows how to use Ethers to interact with Flashbots from JavaScript/TypeScript. The examples can be run in Node.js and the browser.

References:

• https://github.com/ethers-io/ethers.js
• https://github.com/flashbots/ethers-provider-flashbots-bundle

• There's four iterative examples in src/main1.ts (Ethers setup) to src/main4.ts (sending bundles and more).
• They are imported from src/cli.ts and src/browser.ts, for running in the terminal/browser respectively.

Clone the repository and install the dependencies:

git clone [email protected]:metachris/flashbots-ethers-example.git
cd flashbots-ethers-example
yarn

Run the code in Node.js:

yarn cli

Run the code in the browser:

• yarn esbuild-browser:watch
• open browser-test.html in your browser

To change between examples, update the imports in src/cli.ts and src/browser.ts.

The code is free to use however you want, no attribution necessary.
