Use this skill when asked about Ethereum internals, EVM deep dive, Ethereum consensus layer, execution clients, staking, EIPs, layer-2 scaling, account abstraction, PBS/MEV-Boost, EVM opcodes, and Ethereum protocol development. Languages: Go, Rust, C#, C++, Solidity. Covers EVM architecture (opcodes, gas metering, memory/storage model, EOF), execution clients (geth, reth, Nethermind, Erigon), consensus layer (Casper FFG, LMD-GHOST, beacon chain, attestation), staking and validators (32 ETH, withdrawal credentials, MEV-Boost, DVT, ePBS), account abstraction (ERC-4337, EntryPoint, paymasters, UserOp mempool), critical EIPs (1559, 4844, 4337, 3529, 2718), and L2 scaling (Optimism, Arbitrum, ZKsync, StarkNet, validium, data availability). Do NOT use for: Bitcoin protocol (use blockchain-bitcoin), non-EVM blockchains (use blockchain-core), or smart contract development (use blockchain-application).

When should I use the Blockchain Ethereum skill?
Use Blockchain Ethereum when your Claude Code task falls under the Security category — specifically in the security misc area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Blockchain Ethereum" or describe the task and let Claude pick). Browse related skills at /category/security/.
What is a Claude Code skill and how does the Blockchain Ethereum skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Blockchain Ethereum is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.
