**Week 18, April 20 – 27** The week marked a transition from shock to adaptation. Mantle, Lido, and Kulichov's personal fund gathered $87 million to cover Aave's deficit after the Kelp DAO hack, while JPMorgan noted the structural vulnerability of DeFi. Regulators in New York, Illinois, and Kalshi simultaneously closed prediction markets for officials, and the Senate listened to a crypto-heavy candidate for the Federal Reserve Chair. Institutions are purchasing record volumes of BTC/ETH and building TradFi exchanges through M&A and capital investments. DeFi is testing a self-recovery mechanism without external rescuers for the first time. The hole in Aave following the Kelp DAO hack is being patched by the protocol cluster itself rather than institutions. On April 24, Mantle (an L2 supported by Bybit) proposed a loan of 30,000 ETH ($70 million) to Aave, Lido added 2,500 ETH ($5.8 million), and Aave co-founder Stanislav Kulichov made a personal donation of 5,000 ETH ($11.6 million); a total of $87 million against a $196 million hole. A decision on the compensation scenario—18.5% loss allocation, L2 holders’ rsETH write-off, or a pre-hack snapshot—has not been made yet. On the same day, JPMorgan noted that the incident wiped $20 billion from DeFi’s TVL, provoking outflows from pools not associated with the compromised asset, and called cross-chain bridges a structural weakness in the sector. Regulators are simultaneously building a perimeter around prediction markets and stablecoins. The line between a bet, insider knowledge, and a financial contract has finally moved from a gray area to a regulated one. On April 23, the governors of New York (Hochul) and Illinois (Pritzker) signed orders banning officials from participating in prediction markets; Kalshi fined and banned three American politicians for five years for betting on their own elections and brought in the Pyth Network oracle for online data validation. Meanwhile, the US Department of Justice initiated proceedings against soldier Gannon Van Dyke, who earned $410,000 from 13 bets totaling $33,000 on Polymarket using insider information about an operation to capture Maduro—he faces up to 60 years. At a Senate hearing on April 22, Kevin Warsh, a candidate to succeed Powell after May 15, acknowledged owning 30 tokens and stakes in dozens of crypto companies worth $192 million; Warren publicly called him a "puppet" of Trump due to the risks of special Federal Reserve accounts for the administration’s family crypto businesses. TradFi is buying crypto infrastructure rather than tokens—through M&A and capital investments. Institutions are entering crypto as infrastructure investors, not traders. Michael Saylor’s Strategy acquired 34,200 BTC for $2.54 billion—the largest purchase of 2026; the total portfolio reached 815,000 BTC ($62.1 billion), 3.9% of issuance, at an average price of $75,500 (+1%). Bitmine bought an additional 101,600 ETH ($235.5 million)—a record for the year in ETH; their position is now 5 million ETH ($11.6 billion), 4.1% of supply, with $3.8 billion in unrealized Q1 losses. Kraken (Payward) announced on April 20 the acquisition of Bitnomial for $550 million—the first US exchange with all three CFTC licenses for trading crypto derivatives; the acquirer is valued at $20 billion. On April 21, JSCC (Japan Securities Clearing Corporation) launched a pilot for trading Japanese government bonds on the Canton network in partnership with Mizuho, Nomura, and Digital Asset Holdings—aiming for 24/7 collateral and cross-border transactions. Circle introduced the USDC Bridge on April 20 with native mint/burn across 17 EVM networks, eliminating wrapped-USDC. Binance.US introduced 0% maker / 0.02% taker fees for all accounts—98% lower than those of Coinbase (0.40–0.60%) and Kraken (0.25–0.40%); the price war in the US spot market has e
