BroadChain learned that at 16:16 on April 20, according to TechFlow, independent analyst Markus Thielen's chart analysis shows that since October last year, Bitcoin has been continuously adjusting, while Tether's market cap has long hovered around $183 billion, indicating a lack of new capital inflow. Recently, the situation has changed, with Tether's circulation increasing by approximately $3 billion, its market cap recovering to $187 billion, and the overall stablecoin market cap rising, showing signs of market liquidity recovery. Analysts point out that, combined with other capital flow indicators, the signal direction is trending positive but still in its early stages. Such marginal improvements often precede price performance. If this trend continues in the coming weeks, it is expected to support the Bitcoin price.

BroadChain learned that at 16:16 on April 20, according to Bitcoinist, David Schwartz, former Chief Technology Officer of Ripple, discovered a widespread structural issue while evaluating the DeFi cross-chain bridge design for Ripple's stablecoin RLUSD: although system designs typically include robust security mechanisms, teams often opt for simplified configurations in pursuit of operational convenience and rapid expansion, which may be the core trigger for recent security incidents like KelpDAO/rsETH. Schwartz pointed out that many bridging solutions can theoretically effectively defend against similar attacks, but these critical security features are often 'recommended' to be bypassed due to increased operational complexity.

BroadChain learned that at 15:30 on April 20, according to PANews, Spark's strategic lead monetsupply.eth stated that the protocol has been deprecating low-usage assets such as rsETH since January and continuously tightening its collateral scope and feature set. As Spark set a relatively high maximum borrowing rate for the SparkLend ETH market, while Aave lowered its maximum ETH borrowing rate to below 10%, users shifted to borrowing on Aave, causing Spark to lose significant business and revenue over the past year. However, in the current market environment, SparkLend still maintains sufficient ETH withdrawal liquidity, while Aave on the main

BroadChain learned that at 15:30 on April 20, according to TechFlow, on April 20, Spark strategy lead monetsupply.eth stated that Spark has long adhered to setting a higher borrow cap rate for the SparkLend ETH market. While this move caused a significant number of users to switch to Aave, resulting in considerable business and revenue loss, the current market liquidity crisis demonstrates the prudence of this strategy. Currently, Aave's ETH borrowing utilization rate has reached 100% across multiple chain markets including Mainnet, Arbitrum, Plasma, Mantle, and Base, leading to liquidity exhaustion. This has resulted in depositors being unable to withdraw and ETH collateral...

BroadChain learned that at 15:16 on April 20, according to Bitcoinist, after Bitcoin broke through $78,000 last week, market bullish sentiment has heated up again, with some predictions pointing to its return to the six-figure mark. However, cryptocurrency analyst Behdark holds a different view, believing that the current rally may mislead investors or be a strategy by market makers to attract broad participation before prices fall again. He pointed out that Bitcoin's underlying structure remains bearish, as it appears to be forming a triangle or double zigzag correction pattern. Such complex correction patterns are often accompanied by a rebound illusion, followed by further declines. Both patterns suggest that prices may fall first and then rise, providing investors with opportunities to buy on dips. The analyst indicated

BroadChain learned that at 14:16 on April 20, according to PANews, since the SEC approved Bitcoin spot ETFs in January 2024, US cryptocurrency investment channels have significantly matured. As of 2026, investors primarily participate through four major paths: spot ETFs, crypto equity companies (miners and treasury companies), leveraged/inverse ETFs, and blockchain-themed funds. The total size of Bitcoin spot ETFs reached $86.9 billion (as of March 30, 2026), with BlackRock's IBIT holding approximately $55 billion, capturing 60% market share. The total size of Ethereum spot ETFs is about $18 billion (as of the end of 2025), led by BlackRock's ETHA.

BroadChain learned that at 14:16 on April 20, according to TechFlow, affected by the over $200 million bad debt triggered by the rsETH vulnerability under KelpDAO, AAVE is facing a severe liquidity crisis. The utilization rates of all core markets, including USDT and USDC, have reached 100%, resulting in over $3 billion in USDT and $2 billion in USDC deposits being unable to be withdrawn. The crisis began when large capital parties such as Justin Sun and MEXC rapidly withdrew funds, instantly draining the available liquidity in key markets like ETH, USDT, and USDC. Currently, the ETH market is also at 100% utilization, meaning the protocol cannot

BroadChain learned that at 13:16 on April 20, according to PANews, AI is disrupting the traditional software paradigm with a 'capability-as-a-service' model, whose core lies in distilling human organizational patterns and professional expertise into scalable, replicable Agent Skills. This process is accompanied by an explosive growth in Token usage—data shows that the daily Token usage in the Chinese market has surged from 100 billion in 2024 to the current 140 trillion, signaling the dawn of a zero-cost era for content and data production. The trend of Token cheapening is difficult to halt by computing power monopolies, while the DeFi sector has already shown clear signs of a SaaS dilemma: protocols can only charge based on transaction frequency, failing to...

BroadChain learned that at 13:16 on April 20, according to TechFlow, Artemis analyst Zheng Jie pointed out that amidst the overall valuation correction in the DAT (Digital Asset Treasury) sector, Hyperliquid Strategies Inc (NASDAQ: PURR) should not be equated with companies like MicroStrategy. The latter incurs a daily debt cost of $2.3 million, and its mNAV has fallen from a peak of over 6x to 1.15x. PURR holds 18.8 million HYPE, the native token of the Hyperliquid protocol, which generated $857 million in fees in 2025.

BroadChain learned that at 12:30 on April 20, according to TechFlow, on April 20, on-chain data revealed that an OTC whale, affected by the KelpDAO rsETH cross-chain bridge vulnerability, was unable to withdraw ETH normally from Aave. Forced to exchange 7,438 aEthWETH (approximately $16.83 million) at a discount for 1,930 stETH and 5,272 ETH, resulting in a loss of about 237 ETH (approximately $540,000). This whale previously held 163,405 ETH (approximately $440 million) and 4,000 cbBTC (approximately $296 million). Currently, they have withdrawn 98,032 wst from Aave.

BroadChain learned that on April 20 at 12:16, according to TechFlow, on April 18, Kelp DAO suffered a theft of $292 million due to a configuration vulnerability in its LayerZero cross-chain bridge, making it the largest DeFi security incident so far in 2026. The root cause of the vulnerability was that its OFT bridge adopted a 1-of-1 DVN validator node configuration, allowing attackers to forge cross-chain messages and mint 116,500 rsETH out of thin air on the Ethereum mainnet by compromising just a single node. As early as April 6, an open-source AI audit report had explicitly flagged this risk, pointing out that its DVN configuration was opaque, had a single point of failure, and the attack pattern resembled those on Ronin and Harmony.

BroadChain learned that at 11:30 on April 20, according to PANews, the Ethereum restaking protocol Kelp DAO confirmed that its rsETH contract suffered a suspicious cross-chain attack, has suspended mainnet and multiple L2 contracts, and initiated an investigation. Lido has also paused new deposits for its earnETH product. DeFiLlama data shows that the incident triggered a large-scale withdrawal of funds from lending protocols, with Aave experiencing a net outflow of approximately $6.2 billion (-23%). On-chain investigator ZachXBT pointed out that the RAVE token plummeted from $26 to $1 within 24 hours, with its market cap evaporating by about $6 billion, potentially involving market manipulation, as 95% of its supply is controlled by a few addresses. Additionally, Laye
