Ethereum

Ethereum is the second-largest cryptocurrency and the chain most of crypto’s real usage runs on top of. Every major L2, Arbitrum, Base, Optimism, zkSync, Linea, settles back to Ethereum. Most stablecoins live here. Most DeFi is here. The spot ETH ETFs are here. And yet the narrative around ETH has been muddled for a couple of years now, because the L2-heavy roadmap moved activity away from mainnet and most of the fee revenue with it.

This hub tracks what matters: staking dynamics (including the spot-ETF staking variants that finally cleared in late 2025), the EIP pipeline and which upgrades actually ship vs. slip, Ethereum Foundation politics, the Layer 2 ecosystem’s health metrics (TVL, gas cost to L1, bridge security), and the ETH-vs-SOL question that keeps getting uglier.

We don’t pretend to be neutral about a few things. Real-world asset tokenization is happening on Ethereum and there’s a reason the banks picked it over Solana, settlement assurance matters when you’re moving $100 million in tokenized Treasuries. At the same time, Ethereum’s own community has been in public argument for a year about whether the L2-first strategy was correct, and we think the critique has merit. We try to say so when the evidence supports it.

If you’re learning: what is Ethereum and how smart contracts work is the entry point. Live price and market data are at /coins/ethereum/. For the ecosystem-wide view, the Layer 2 sector page and Ethereum Ecosystem both aggregate live data.
