Deployment Files

Each deployment is recorded in a JSON file with the following information:

• Network details (chain ID, name, RPC URLs)
• Deployed contract addresses
• Deployment transaction hashes
• Gas costs and block numbers
• Explorer links
• Network features (RIP-7212, ERC-4337, etc.)

Common Addresses

EntryPoint v0.7 (Canonical)

• Address: 0x0000000071727De22E5E9d8BAf0edAc6f37da032
• Networks: All supported networks (deterministic deployment)
• Specification: ERC-4337

Solady ERC1967Factory (Canonical)

• Address: 0x0000000000006396FF2a80c067f99B3d2Ab4Df24
• Networks: All supported networks
• Purpose: Minimal proxy factory for gas-efficient account deployments

Deployment Process

To deploy to a new network:

1. Setup Environment

   # Add network RPC to .env
   NETWORK_RPC_URL=https://...

2. Deploy Factory

   forge script script/Deploy.s.sol:DeployScript \
     --rpc-url <network> \
     --broadcast \
     --verify

3. Record Deployment

   • Create <network>.json in this directory
   • Update README.md with deployment details
   • Update frontend NetworkContext.jsx

4. Verify Contracts

   forge verify-contract \
     --chain-id <chain-id> \
     <factory-address> \
     src/P256AccountFactory.sol:P256AccountFactory

Network Requirements

For a network to support EthAura:

• ✅ ERC-4337 Support: EntryPoint v0.7 deployed
• ✅ Bundler Availability: At least one bundler service
• ✅ RIP-7212 (Recommended): P256 precompile for gas efficiency
• ✅ Block Explorer: For contract verification and transaction viewing
