Crypto News Today (April 21): Bitcoin Pumps as Saylor Buys $2.55B, Clarity Act Faces May Delay, Arbitrum Freezes $71M

Crypto is doing solid today, on April 21. Both Bitcoin and total crypto market cap are up roughly 2% in the last 24 hours. Bitcoin is now above $75,500, and altcoins are following along as usual.

But there are no crazy, uncontrolled pumps like we had with RaveDAO this month. With this in mind, let's explore the main crypto news today.

Bank Pressure Clouds Clarity Act Timeline

A lobbying campaign led by banking trade groups could push a markup of crypto market structure legislation to May. The Senate Banking Committee was expected to take up the bill in late April, but ongoing pressure from banks unhappy with stablecoin yield restrictions is causing delays.

The North Carolina Bankers Association is urging member banks to call Senator Thom Tillis' office, arguing the current compromise "does not accomplish the goal" of preventing deposit flight to stablecoins.

White House Crypto Council Executive Director Patrick Witt fired back, saying it's "hard to explain any further lobbying on this issue as motivated by anything other than greed or ignorance." With the committee's calendar filling up and a recess looming, a markup is now more likely to slip to the second week of May.

Lido Discloses $21.6M rsETH Exposure, May Deploy $3M Loss Buffer

Following the April 18 KelpDAO cross‑chain bridge exploit that stole 116,500 rsETH (roughly $292 million), Lido disclosed that its EarnETH vault holds approximately $21.6 million in rsETH exposure (about 9% of the vault's assets) through leveraged positions on Aave.

The EarnETH team is actively deleveraging and reducing risks. If necessary, Lido may deploy a ~$3 million first‑loss protection mechanism funded by its DAO treasury. Lido stressed that stETH and wstETH remain unaffected, and the core staking protocol is not involved.

Vitalik: L2s That Only Copy Ethereum Make No Sense

Ethereum founder Vitalik Buterin stated during his keynote speech at the 4th Hong Kong Web3 Festival on April 20 that an L2 which merely clones Ethereum and makes it more centralized is "meaningless." A truly meaningful L2 should examine application needs and build the required off‑chain components outside of Ethereum L1.

He also noted that future scaling remains a key focus: first, data scaling via further advancing the PeerDAS technology, and second, compute scaling to allow different applications to compose and communicate without intermediaries.

Arbitrum Security Council Freezes 30,766 ETH Linked to KelpDAO Exploit

The Arbitrum Security Council has taken emergency action to freeze 30,766 ETH (valued at approximately $71.1 million) held in an address on Arbitrum One connected to the KelpDAO exploit. The council identified and executed a technical approach to move the funds to safety without affecting any other chain state or Arbitrum users.

Overall, it's a pretty slow day actually, with all eyes on what will happen with the Clarity Act this month and possibly in May. This is a very important bill for crypto because it would finally provide a clear regulatory framework for digital assets, splitting oversight between the SEC and CFTC and giving institutional investors the compliance cover they need to increase allocations.

Without it, the current regulatory uncertainty will persist, keeping billions in sidelined capital on the sidelines.
