Skill based on go-ethereum (geth), generated 2026-02-09. Official docs: https://geth.ethereum.org/docs
Go Ethereum (geth) is the Golang execution-layer client for Ethereum. It runs full/archive/light nodes, exposes JSON-RPC over HTTP/WebSocket/IPC, and ships tools like Clef (signer) and abigen (Go contract bindings).
