What is MegaETH Development Skill?
This Openclaw Skills resource provides an end-to-end framework for MegaETH development, focusing on the unique MegaEVM multidimensional gas model and real-time transaction processing. It empowers developers to leverage EIP-7966 for instant transaction receipts and optimize storage using advanced patterns like Solady RedBlackTreeLib to minimize costs on the network.
By integrating this skill, developers can efficiently manage Foundry projects, handle complex wallet operations via Privy and MetaMask Smart Accounts, and implement on-chain hosting with Warren Protocol. It serves as a technical bridge for those migrating from standard Ethereum development to the ultra-high-throughput environment of MegaETH.
MegaETH Development Skill Use Cases
- Setting up Foundry projects specifically optimized for MegaETH mainnet and testnet.
- Implementing instant transaction feedback loops using eth_sendRawTransactionSync for sub-10ms receipts.
- Developing storage-efficient smart contracts using transient storage and specialized libraries.
- Integrating automated signing and headless wallet operations for AI agents or automated bots.
- Deploying on-chain websites and managing .mega naming services for decentralized identity.
How MegaETH Development Skill Works
- Classify the development task into layers: Frontend, RPC/Transaction, Smart Contract, or Testing.
- Configure the environment with MegaETH specific chain IDs such as 4326 for Mainnet or 6343 for Testnet.
- Implement high-performance RPC patterns, prioritizing Multicall for batching and WebSocket keepalives for real-time streaming.
- Apply MegaEVM-specific gas strategies, such as hardcoding limits to skip estimation round-trips.
- Verify and debug using specialized tools like mega-evme for opcode-level profiling.
MegaETH Development Skill Setup
To begin using this skill within Openclaw Skills, ensure your development environment is prepared for MegaETH specifications. Install Foundry and configure your RPC endpoints to point to MegaETH nodes.
# Initialize a MegaETH compatible Foundry project
forge init my-mega-project
# Set RPC environment variables
export MEGA_RPC_URL=https://mainnet.megaeth.com/rpc
For real-time features, ensure your WebSocket client implements a keepalive sending eth_chainId every 30 seconds.
MegaETH Development Skill Data Schema & Taxonomy
The skill organizes MegaETH development data through the following taxonomy:
| Layer | Key Components | Optimization Focus |
|---|---|---|
| Transaction | EIP-7966, RawSync | Latency reduction (<10ms receipts) |
| Storage | RedBlackTreeLib, Transient Slots | Slot reuse to avoid 2M gas SSTORE costs |
| Identity | MegaNames (.mega) | Subdomain marketplace and text records |
| Permissions | ERC-7710, ERC-7715 | Scoped delegation and session keys |
MegaETH Development Skill Advanced Features
- Support for ERC-7710 delegation frameworks allowing for scoped on-chain permissions and redelegation chains.
- Integration with Meridian and x402 for seller-side settlement and automated buyer-side USDm forwarder approvals.
- Advanced mini-block streaming via WebSockets for real-time dApp frontend updates.
- On-chain website hosting capabilities via the Warren Protocol integration.
- Specialized debugging using the mega-evme CLI for transaction replaying and gas profiling by opcode.
