Ethereum & Altcoins
Ethereum and the broader altcoin universe drive most of the daily news flow in crypto — every protocol upgrade, every L2 launch, every validator-economics change, every altcoin rotation. LeoDex News covers Ethereum's roadmap (Pectra, Verkle trees, danksharding) alongside the L2 ecosystem (Arbitrum, Optimism, Base, zkSync) and the major non-Bitcoin assets that move markets (SOL, XRP, NEAR, ICP, AVAX, and more).
We focus on the mechanism, not the meme. When NEAR rallies 19% in a session, we explain what shipped to drive it. When validator queues spike, we trace it to the staking-derivatives flow. When a new L2 ships, we surface the actual tradeoffs vs the existing ones. Trade these assets on LeoDex — non-custodial, no signup, 100+ DEXes across 60+ chains.
