  1. 1

    Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

MegaETH Development Skill

What this Skill is for

Use this Skill when the user asks for:

  • Wallet setup and management on MegaETH
  • Sending transactions, checking balances, token operations
  • Token swaps via Kyber Network aggregator
  • MegaETH dApp frontend (React / Next.js with real-time updates)
  • RPC configuration and transaction flow optimization
  • Smart contract development with MegaEVM considerations
  • Storage optimization (avoiding expensive SSTORE costs)
  • Gas estimation and fee configuration
  • Testing and debugging MegaETH transactions
  • WebSocket subscriptions and mini-block streaming
  • Bridging ETH from Ethereum to MegaETH

Chain Configuration

| Network | Chain ID | RPC | Explorer | |---------|----------|-----|----------| | Mainnet | 4326 | https://mainnet.megaeth.com/rpc | https://mega.etherscan.io | | Testnet | 6343 | https://carrot.megaeth.com/rpc | https://megaeth-testnet-v2.blockscout.com |

Default stack decisions (opinionated)

1. Transaction submission: eth_sendRawTransactionSync first

  • Use eth_sendRawTransactionSync (EIP-7966) — returns receipt in <10ms
  • Eliminates polling for eth_getTransactionReceipt
  • Docs: https://docs.megaeth.com/realtime-api

2. RPC: Multicall for eth_call batching (v2.0.14+)

  • Prefer Multicall (aggregate3) for batching multiple eth_call requests
  • As of v2.0.14, eth_call is 2-10x faster; Multicall amortizes per-RPC overhead
  • Still avoid mixing slow methods (eth_getLogs) with fast ones in same request

Note: Earlier guidance recommended JSON-RPC batching over Multicall for caching benefits. With v2.0.14's performance improvements, Multicall is now preferred.

3. WebSocket: keepalive required

  • Send eth_chainId every 30 seconds
  • 50 connections per VIP endpoint, 10 subscriptions per connection
  • Use miniBlocks subscription for real-time data

4. Storage: slot reuse patterns

  • SSTORE 0→non-zero costs 2M gas × multiplier (expensive)
  • Use Solady's RedBlackTreeLib instead of Solidity mappings
  • Design for slot reuse, not constant allocation

5. Gas: skip estimation when possible

  • Base fee stable at 0.001 gwei, no EIP-1559 adjustment
  • Ignore eth_maxPriorityFeePerGas (returns 0)
  • Hardcode gas limits to save round-trip
  • Always use remote eth_estimateGas (MegaEVM costs differ from standard EVM)

6. Debugging: mega-evme CLI

  • Replay transactions with full traces
  • Profile gas by opcode
  • https://github.com/megaeth-labs/mega-evm

Operating procedure

1. Classify the task layer

  • Frontend/WebSocket layer
  • RPC/transaction layer
  • Smart contract layer
  • Testing/debugging layer

2. Pick the right patterns

  • Frontend: single WebSocket → broadcast to users (not per-user connections)
  • Transactions: sign locally → eth_sendRawTransactionSync → done
  • Contracts: check SSTORE patterns, avoid volatile data access limits
  • Testing: use mega-evme for replay, Foundry with --skip-simulation

3. Implement with MegaETH-specific correctness

Always be explicit about:

  • Chain ID (4326 mainnet, 6343 testnet)
  • Gas limit (hardcode when possible)
  • Base fee (0.001 gwei, no buffer)
  • Storage costs (new slots are expensive)
  • Volatile data limits (20M gas after block.timestamp access)

4. Deliverables expectations

When implementing changes, provide:

  • Exact files changed + diffs
  • Commands to build/test/deploy
  • Gas cost notes for storage-heavy operations
  • RPC optimization notes if applicable
