Summary

Ethereum (ETH) is the second-largest cryptocurrency by market capitalization (~$278 billion as of May 2026) and the leading smart-contract platform, hosting the majority of decentralized finance (DeFi) and NFT activity. The protocol has a documented history of governance controversy stemming from the 2016 DAO hack hard fork, ongoing centralization concerns around liquid staking and MEV infrastructure, and persistent smart-contract and phishing-based fraud targeting end users, though Ethereum itself has not been the subject of any regulatory enforcement action and its spot ETFs have received SEC approval.
