Does this skill support the MegaETH testnet?

Yes, it includes pre-configured settings for both Mainnet (Chain ID 4326) and the Carrot Testnet (Chain ID 6343).

How does it optimize gas estimation?

It provides guidance on using remote eth_estimateGas since MegaEVM costs differ from standard EVM, and suggests hardcoding limits when possible to save RPC round-trips.

How does this skill handle MegaETH transaction receipts?

It prioritizes EIP-7966 (eth_sendRawTransactionSync), which allows the network to return a transaction receipt in under 10ms, eliminating the need for traditional polling.

What is the recommended storage pattern for MegaETH?

The skill recommends slot reuse patterns and libraries like Solady's RedBlackTreeLib instead of standard Solidity mappings to avoid the high costs of initializing new storage slots.
