Setup snapshot

git clone https://github.com/clawdybotty/megaeth-foundry-developer.git
  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 + Foundry Development Skill

Sources & Attribution

When to use this Skill

Use when the user asks about:

  • Building anything on MegaETH (contracts, dApps, scripts)
  • Foundry project setup targeting MegaETH
  • Writing tests (unit, fuzz, invariant) for MegaETH contracts
  • Deploying and verifying contracts on MegaETH
  • Wallet operations, token swaps, bridging
  • Gas optimization or storage patterns on MegaEVM
  • RPC configuration, WebSocket subscriptions, real-time features
  • Debugging failed transactions on MegaETH

Chain Configuration

| Parameter | Mainnet | Testnet | |-----------|---------|---------| | Chain ID | 4326 | 6343 | | HTTP RPC | https://mainnet.megaeth.com/rpc | https://carrot.megaeth.com/rpc | | WebSocket | wss://mainnet.megaeth.com/ws | wss://carrot.megaeth.com/ws | | Explorer | https://mega.etherscan.io | https://megaeth-testnet-v2.blockscout.com | | Native Token | ETH | ETH |

Critical MegaETH differences from standard EVM

Know these before writing any code:

  1. Intrinsic gas = 60,000 (not 21,000) — 21K compute + 39K storage gas
  2. Multidimensional gas — compute gas + storage gas are separate dimensions
  3. SSTORE 0→nonzero — 22,100 compute + 20,000×(m-1) storage gas (m = bucket multiplier). Expensive at high multipliers.
  4. Gas forwarding ratio: 98/100 (not 63/64 like Ethereum) — more gas available in nested calls
  5. Per-tx resource limits: 200M compute gas, 500K KV updates, 1,000 state growth slots, 12.5MB data
  6. Base fee: stable at 0.001 gwei, no EIP-1559 dynamics
  7. Volatile data: after accessing block.timestamp/block.number/blockhash(), tx limited to 20M additional compute gas — access metadata late
  8. LOG opcodes: quadratic cost above 4KB data
  9. Contract size: 512KB max, calldata 128KB max
  10. Transient storage (EIP-1153): TSTORE/TLOAD available — use to avoid storage gas costs for temporary data

Sources: Claims 1-2, 4-5 validated against MegaEVM spec. Claims 3, 6-10 from 0xBreadguy skill, testnet-verified pre-mainnet.

Default stack decisions

  1. Transaction submission: eth_sendRawTransactionSync (EIP-7966) — instant receipt in <10ms
  2. RPC batching: Multicall (aggregate3) preferred over JSON-RPC batching (since v2.0.14)
  3. WebSocket: keepalive every 30s via eth_chainId; 50 connections/endpoint, 10 subs/connection
  4. Storage: Solady RedBlackTreeLib over mappings; prefer transient storage for temp data
  5. Gas: hardcode when possible; always use remote eth_estimateGas (MegaEVM costs differ)
  6. Testing: Foundry with --skip-simulation (Foundry ignores storage gas)
  7. Debugging: mega-evme CLI for transaction replay and gas profiling

Operating procedure

1. Classify the task layer

2. Implement with MegaETH-specific correctness

Always be explicit about:

  • Chain ID (4326 mainnet, 6343 testnet)
  • Gas limit (hardcode when possible, use remote estimation otherwise)
  • Base fee (0.001 gwei, no buffer)
  • Storage costs (new slots are expensive — prefer transient storage or slot reuse)
  • Volatile data limits (20M gas after block.timestamp access)
  • Gas forwarding (98/100 — more gas available in nested calls than on Ethereum)

3. Deliverables expectations

When implementing changes, provide:

  • Exact files changed + diffs
  • Commands to build/test/deploy
  • Gas cost notes for storage-heavy operations
  • foundry.toml configuration if setting up a new project
