This repository contains the JavaScript source code for the Fuse Uniswap V2 TWAP Bot. See here for the Fuse dApp, here for the Fuse SDK, or here for the Fuse contracts.

This bot updates on-chain price data for Fuse pools via TWAPs of Uniswap V2 (and SushiSwap) pairs based in ETH. If you are using prices for which others are not reliably posting TWAPs, you will need to run a bot and a redundancy bot; if others are reliably posting TWAPs, simply run your own redundancy bot for additional security. Note that the more often you update the oracle and the more assets you do so for, the ETH you will spend on gas fees. However, also note that infrequent updates to an asset's price could leave room for attackers to profit via arbitrage at the expense of your users.

You'll want to run the script on the latest Node.js LTS (tested with v12.16.1) with the latest version of NPM.
