DEPRECATED => moved to monorepo/packages/ui

Web 2 Infra: AWS Resources

Repository for all AWS resources related to Midas Capital. These are mainly comprised of liquidation bots and TWAP bots, and the configs necessary to deploy them reliably and scalably.

Components

Terraform Modules:

ecs: ECS cluster definition and Autoscaling Group
ec2: EC2 launch configuration
ecr: permissions for ECS <-> ECR access
networking: networking stacks
liquidation: container definition for a liquidation bot
twap: container definition for a TWAP bot (TODO)

Adding a Liquidation Bot

Go to config/main.tf and duplicate the following code block:

module "bsc_testnet_liquidation_bot" {
  source                      = "./modules/liquidation"
  ecs_cluster_sg              = module.network.ecs_task_sg
  allow_all_sg                = module.network.allow_all_sg
  execution_role_arn          = module.ecr.execution_role_arn
  cluster_id                  = module.ecs.ecs_cluster_id
  vpc_id                      = module.network.vpc_id
  public_subnets              = module.network.public_subnets
  docker_image                = "ghcr.io/midas-protocol/fuse-liquidator-bot:<sha:commit-hash>"
  container_family            = "liquidation"
  chain_id                    = "97"
  cpu                         = 128
  memory                      = 64
  instance_count              = 1
  timeout                     = 180
  ethereum_admin_account      = var.ethereum_admin_account
  ethereum_admin_private_key  = var.ethereum_admin_private_key
  supported_input_currencies  = "0x0000000000000000000000000000000000000000,0xEC5dCb5Dbf4B114C9d0F65BcCAb49EC54F6A0867"
  supported_output_currencies = "0x0000000000000000000000000000000000000000,0xEC5dCb5Dbf4B114C9d0F65BcCAb49EC54F6A0867"
  web3_provider_url           = "https://data-seed-prebsc-1-s1.binance.org:8545"
}

Change the name of the module to something meaningful, e.g. evmos_mainnet_liquidation_bot

Edit the fields:

supported_input_currencies
supported_output_currencies
web3_provider_url
chain_id

For the docker_image you can find the latest commit hash in the fuse-liquidator-bot image releases

Commit and push. CI will take care of deploying the bot.

Adding a TWAP Bot

Same as before, but with the following block:

module "bsc_mainnet_twap_bot" {
  source                     = "./modules/twap"
  ecs_cluster_sg             = module.network.ecs_task_sg
  allow_all_sg               = module.network.allow_all_sg
  execution_role_arn         = module.ecr.execution_role_arn
  cluster_id                 = module.ecs.ecs_cluster_id
  docker_image               = "ghcr.io/midas-protocol/fuse-twap-bot:<sha:commit-hash>"
  container_family           = "twap"
  chain_id                   = "97"
  cpu                        = 128
  memory                     = 64
  instance_count             = 1
  timeout                    = 180
  ethereum_admin_account     = var.ethereum_admin_account
  ethereum_admin_private_key = var.ethereum_admin_private_key
  supported_pairs            = "0x58F876857a02D6762E0101bb5C46A8c1ED44Dc16|0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c,0x74E4716E431f45807DCF19f284c7aA99F18a4fbc|0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c,0x61EB789d75A95CAa3fF50ed7E47b96c132fEc082|0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c"
  web3_provider_url          = "https://data-seed-prebsc-1-s1.binance.org:8545"
}

Edit the fields:

supported_pairs
web3_provider_url
chain_id

supported_pairs format: comma separated <pair_address>|<base_token> values. pair_address is the pair's address as calculated by the Uniswap Factory getPair function, and the base token is the base token of the pair.
