Hello World AVS

Welcome to the Hello World AVS.

This project shows you the simplest functionality you can expect from an AVS.

It will give you a concrete understanding of the basic components.

There are 5 steps to this AVS:

• AVS consumer requests a "Hello World" message to be generated and signed
• AVS takes on the request by emitting an event for operators to pick up the request
• any operator who is staked to serve this AVS takes this request, generates this message and signs it
• the operator submits this message with their signature back to the AVS
• if the operator is in fact registered to the AVS and has the minimum needed stake, the submission is accepted

That's it. This simple flow highlights some of the core mechanics of how AVSs work.

Where additional sophistication with AVSs come into the picture:

• the nature of the request is more sophisticated than generating a constant string
• the operators might need to coordinate with each other
• the type of signature is different based on the constraints of the service
• the type and amount of security used to secure the AVS
• and so on...

Quick Start

Dependencies

1. npm
2. Foundry
3. Docker
   • Make sure Docker is running

Following NodeJS packages:

1. tcs
2. ethers

Steps

Typescript

1. Run yarn install
2. Run cp .env.local .env
3. Run make start-chain-with-contracts-deployed
   • This will build the contracts, start an Anvil chain, deploy the contracts to it, and leaves the chain running in the current terminal
4. Open new terminal tab and run make start-operator
   • This will compile the AVS software and start monitering new tasks
5. Open new terminal tab and run make spam-tasks (Optional)
   • This will spam the AVS with random names every 15 seconds

Rust lang

Anvil

1. Run make start-chain-with-contracts-deployed

   • This will build the contracts, start an Anvil chain, deploy the contracts to it, and leaves the chain running in the current terminal

2. Run make start-rust-operator

3. Run make spam-rust-tasks

Tests are supported in anvil only . Make sure to run the 1st command before running the tests:

cargo test --workspace

Holesky Testnet

Contract Name	Holesky Address
Hello World Service Manager	0x3361953F4a9628672dCBcDb29e91735fb1985390
Delegation Manager	0xA44151489861Fe9e3055d95adC98FbD462B948e7
Avs Directory	0x055733000064333CaDDbC92763c58BF0192fFeBf

You don't need to run any script for holesky testnet.

1. Use the HOLESKY_ namespace env parameters in the code , instead of normal parameters.

2. Run make start-rust-operator

3. Run make spam-rust-tasks

Extensions

• Operator needs a minimum stake amount to make submissions
• Add another strategy to the AVS
• Operator must respond within a certain number of blocks

Deployment on Holesky

To deploy the Hello World AVS contracts to the Holesky network, follow these steps:

1. Ensure you have the necessary RPC URL and private key for the Holesky network.
2. Run the deployment script using Foundry:

   forge script script/HoleskyDeployer.s.sol:HoleskyDeployer --rpc-url $RPC_URL --private-key $PRIVATE_KEY --broadcast -vvvv

   Replace $RPC_URL with your Holesky RPC URL and $PRIVATE_KEY with your private key.

Adding a New Strategy

To add a new strategy to the Hello World AVS, follow the guide provided in AddNewStrategy.md. This guide walks you through the necessary steps to add and whitelist a new strategy for the AVS.
