Blockhead Automation Layer for Linea

The blockhead project contains two parts:

  1. The Blockhead Automation Layer for Linea is a series of smart contracts that enables the automation of functions in other smart contracts that integrate the Blockhead Automation Layer.

  2. Blockhead Finance is a self-custody subscription payment dapp. It is the first proof-of-concept app fully automated by the Blockhead Automation Layer.

The Problem Being Solved by Blockhead Finance

Every SAAS company and millions of other companies are based on a subscription business model. Currently, there is no easy way to allow for subscription payments with crypto. This is because of the push vs pull nature of crypto transactions.

Blockhead Finance is the first Dapp to utilize the magic of the Blockhead Automation Layer to overcome the push vs pull problem and enable full self-custody, decentralized subscription payments on Linea.

The Bigger Problem Being Solved by the Blockhead Automation Layer

Smart contracts are not self-executing, they always require an off-chain user to call the contract to make a transaction or update the on-chain state. But there are many instances where automation is needed. If you want a function to execute on regular time intervals such as with recurring payments, dollar-cost averaging, or compounding staking rewards. Maybe you want to set a buy price for WETH and have a contract automatically swap at that limit order price. These all require a very dedicated team member watching the state of the blockchain 24/7 or they all require automation.

Blockhead has built the automation layer for Linea. Linea developers can now integrate the Blockhead Automation Layer into their new or existing contracts and have a decentralized network of nodes automate simple transactions automagically.

#Blockhead Automation Layer for Linea

The blockhead project contains two parts:

  1. 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.

  2. 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

Bounty 3: IYKYK Linea Addition

Both the blockhead Automation Layer and Blockhead Finance recurring Payments are live on Linea

Blog Post Title Three

It all begins with an idea.

It all begins with an idea. Maybe you want to launch a business. Maybe you want to turn a hobby into something more. Or maybe you have a creative project to share with the world. Whatever it is, the way you tell your story online can make all the difference.

Don’t worry about sounding professional. Sound like you. There are over 1.5 billion websites out there, but your story is what’s going to separate this one from the rest. If you read the words back and don’t hear your own voice in your head, that’s a good sign you still have more work to do.

Be clear, be confident and don’t overthink it. The beauty of your story is that it’s going to continue to evolve and your site can evolve with it. Your goal should be to make it feel right for right now. Later will take care of itself. It always does.
