Chainlink Automation scaling & loadbalancing

Motivation

Nobody likes out-of-gas.

In Cexles we need to scale Chainlink Automation to perform a huge number of on-chain operations in a single block and distribute their execution between multiple Chainlink Nodes without manual user intervention. This software will allow us to unlock the full potential of Chainlink Automation.

Current stage

We started an initial development of MVP with smart contracts deployed on Goerli Ethereum testnet. MVP PoC version. Needs refactor & minor bug fixing.

Desired result

Hassle-free automated scaling for any Chainlink Automation compatible contract.

TODO

• Initial research
• Initial project skeleton
• Sample test smart contract
• Multiple contracts support
• Automated upkeeps creating
• Upkeeps load metrics
• Automated on-condition upkeeps scaling
• Upkeeps scailing prediction
• Automated Upkeep's balance top-up
• API
• Dashboard
• Tests
• Reference contract implementation
• Public Docs

Setup config

• Create and fill config.yaml file

  cp ./goerli.example.config.yaml ./config.yaml
  

• Config

    account:
    # Your private key with Link balance (https://faucets.chain.link/ free testnet faucet)
    private_key: ""
  network:
    rpc_url: "wss://"   # Node websocket (Quicknode best choice)
    chain_id: 5 # goerli chain_id, change to needed
  contracts:
    sample_test: # key of your contract
      name: "Sample test contract" # contract name, used just for logging
      short_name: "sampletest" # short contract name, used for creating new upkeep
      address: "0xCb1Ad0A9D12993CB614533Cd19e7f9f555F13816" # sepolia
      version: "0_1" # version of contract, used for creating new upkeep
      gas_limit: 5000000 # upkeep's gasLimit used for creating new upkeep
      execution_limit: 5 # max upkeep execution limit, check Scale Policy docs section https://docs.cexles.finance/architecture/scale-policy
  chainlink:
    registry_version: "2_0"

    token_address: "0x779877A7B0D9E8603169DdbD7836e478b4624789" # LINK token address, check Chainlink docs
    min_controller_approve: "300000000000000000000" # lower allowance threshold in WEI to execute IncreaseAllowance
  app:
    log_level: -1   # Log level from -1 (more logs) to 5 (fewer logs)
    active_contract_key: "sample_test" # put the key from contracts config section
  

Installing

• Install Docker and Docker Compose

• Copy config file

  cp goerli.example.config.yaml config.yaml
  

• Set config values according to docs

• Run build

  docker-compose build
  

• Run balancer

  docker-compose up -d
  

• Check program logs. If everything is fine you will see something similar to:

  INF upkeep controller found address=0x3911d7499d72dd5f4ea88270af6dfeced1a1bef6
  INF logic contract found name="Cexles platform contract" short_name=cexles_platform version=1_0
  INF subscribed to NewHead event func=StartBlockListener module=service.ChainService
