megaeth-developer

End-to-end MegaETH development playbook (Feb 2026). Covers wallet operations, token swaps (Kyber Network), eth_sendRawTransactionSync (EIP-7966) for instant receipts, JSON-RPC batching, real-time mini-block subscriptions, storage-aware contract patterns (Solady RedBlackTreeLib), MegaEVM gas model, WebSocket keepalive, bridging from Ethereum, and debugging with mega-evme. Use when building on MegaETH, managing wallets, sending transactions, or deploying contracts.

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 instea...
