#Blockhead Automation Layer for Linea
The blockhead project contains two parts:
The Blockhead Automation Layer for Linea is a smart contract layer that enables Linea builders to automate simple functions within their contracts. Builders simply include the Blockhead Automation Layer implementation into their smart contracts and a decentralized network of nodes will mange the automation.
Blockhead Finance is a fully self-custody subscription payment dapp. It is the first proof-of-concept app fully automated by the Blockhead Automation Layer.#How to create a subscription payment with Blockhead Finance.

Bounty 1: To Infura and Beyond
Blockhead Automation Nodes rely heavily on infura WebSocket endpoints. As their only function is to check every Automated function every 60 seconds to determine parameters have been met to call that function, and if true, call that function. The node Infura websocket implementation are all in the automationNodes folder.
Linea Websocket Endpoint -> lineaAutomationNode.js
Linea Goerli Websocket Endpoint - > lineaGoerliAutomationNode.js & testNode.js
Polygon Websocket Endpoint -> polygonAutomationNode.js
Sepolia Websocket Endpoint -> sepoliaAutomationNode.js
The Blockhead Finance dapp utilized the RPC endpoints for each chain the dapp is deployed.
The actual Endpoint URLs are stored locally in a .env file and are not shared for security reasons
