Evera Smart Contarct

Mint anything RWA with Eigenlayer - AVS operator as assets validator

Foundry

Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.

Foundry consists of:

• Forge: Ethereum testing framework (like Truffle, Hardhat and DappTools).
• Cast: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
• Anvil: Local Ethereum node, akin to Ganache, Hardhat Network.
• Chisel: Fast, utilitarian, and verbose solidity REPL.

AVS Deployment

This repository contains a refactored AVS (Actively Validated Service) integrated with EigenLayer middleware. The contract has been optimized to fit within Ethereum's contract size limits.

Contract Architecture

The AVS architecture has been modularized into several components:

1. AVS.sol: The main contract that implements the EigenLayer AVS interface
2. SignatureVerifier.sol: Library for handling signature verification
3. TaskManager.sol: Library for managing task creation and responses
4. SlasherHandler.sol: Contract for handling slashing operations

Setup

1. Copy the example environment file:

   cp deploy.env.example .env
   

2. Fill in your environment variables in the .env file:

   • PRIVATE_KEY: Your deployment wallet's private key
   • EigenLayer contract addresses (already filled with mainnet addresses):
     • AVS_DIRECTORY: 0xb8f3221bf7974f1682d0acbc2f40ba3597db3151
     • STAKE_REGISTRY: 0xe62a528fa2787b7ba2399506d94d82c98fafd01a
     • REWARDS_COORDINATOR: 0x16a26002119c039de57b051c8e8871b0ae8f2768
     • DELEGATION_MANAGER: 0xff8e53df56550c27bf6a8baadc839ed86a7c99d7
     • ALLOCATION_MANAGER: 0x51ff720105655c01be501523dd5c2642ce53fdde
   • Optional owner and rewards initiator addresses

Deployment

Prerequisites

• Foundry installed (Installation guide)
• Access to EigenLayer contracts on your target network
• Sufficient ETH for deployment

Deploy using Forge script

# Install dependencies
forge install

# Build the contracts
forge build

# Deploy to mainnet
forge script script/DeployAVS.s.sol:DeployAVS --rpc-url $RPC_URL --broadcast --verify

# Deploy to testnet (specify the network)
forge script script/DeployAVS.s.sol:DeployAVS --rpc-url $RPC_URL --broadcast --verify --chain-id $CHAIN_ID

Verify deployment

After deployment, the script will output the addresses of the deployed contracts:

• AVS contract address
• Slasher contract address

Contract Size

The AVS contract has been optimized to fit within Ethereum's contract size limit:

• Original size: 28,919 bytes (exceeds the 24,576 byte limit)
• Refactored size: 22,091 bytes (well below the limit)

Usage

Once deployed, the AVS contract can be used to:

• Create verification tasks for real-world assets
• Submit verification responses
• Slash operators for malicious behavior
• View task and response data
