April 21 – Glassnode noted in its latest report that ongoing strong buying interest is propping up prices, but market sentiment is shifting cautious. Data shows spot Cumulative Volume Delta (CVD) flipped from positive to negative, selling pressure is mounting, and bearish sentiment is building. Meanwhile, trading volume on centralized exchanges stays elevated. In futures markets: Rising open interest signals growing risk appetite—but long funding rates have dropped sharply. Perpetual futures CVD has nosedived, meaning traders are more willing to pay a premium to short, buying momentum has weakened, and bearish sentiment is ramping up.

On April 21, the x402 Foundation—incubated by Coinbase—launched Agent.market, a unified platform designed to serve as an "App Store" for AI agents. Built on the x402 protocol, the platform lets users and AI agents connect to hundreds of tools and services.

On April 21, Lido said in a social media post that its EarnETH treasury was hit by a theft of 116,500 rsETH (roughly $292 million) via the Kelp DAO cross-chain bridge on April 18.

The EarnETH team is actively deleveraging to reduce risk, with the outcome dependent on Kelp, LayerZero, and Aave’s final decisions on loss sharing and default handling. Lido added that EarnETH has a $3 million “first-loss protection mechanism” funded by the Lido DAO treasury, which will cover losses if needed. The treasury has temporarily paused redemptions to assess the damage. This incident does not impact stETH or wstETH, as Lido’s core staking protocol was not involved.
