Forta Flashloan Detector Bot on AAVE protocol

forta-flashloan-detector

The forta-flashloan-detector library checks if a transaction on the AAVE Lending protocol contains a flashloan. It currently supports only the Ethereum network and supports Aave protocol, but may include and support many more if included

Dependencies

This package depends on the forta-agent package.

Installation

Use the node package manager npm to add the library to your project:

$ npm install forta-flashloan-detector

Usage

Import the forta-flashloan-detector library into a JavaScript file like this:

const FlashloanDetector = require('forta-flashloan-detector');

Specify the protocols you want to support (in this case AAVE, but if you don't specify any protocol the detector will support all included in the list):

const flashloanDetector = new FlashloanDetector(['aave']);

If you include other protocol apart from AAVE, call the init function to fetch dynamically markets for some of the protocols

await flashloanDetector.init();

Examples

const flashloanDetector = new FlashloanDetector(['aave', 'maker']);

const initialize = async () => {
  await flashloanDetector.init();
};

const handleTransaction = async (txEvent) => {
  const findings = [];

  const flashloanProtocols = flashloanDetector.getFlashloans(txEvent);

  if (flashloanProtocols.length > 0) {
      findings.push(createAlert(flashloanProtocols));
  }

  return findings;
}
