Futureswap bots Terraform

This repo allows you to deploy the Futureswap bots to DigitalOcean VPSs via Terraform.

There are two bots (so far): Tyrannosaurus Rekt (Liquidation Bot) ELK (Internal Exchange Bot)

As more bots get created, I will add support for them here.

Each bot is deployed to it's own VPS (default size is s-1vcpu-1gb, the cheap $5/mo or $0.07/hour one). Can be changed in variables.tf for larger instances.

CloudFlare is optional. It's used to assign a subdomain to the droplets so you can access them more easily. It's commented out by default.
