BroadChain learned that at 10:16 on April 20th, according to PANews, Singapore-based crypto custody and wallet service provider Cobo has launched the Cobo Agentic Wallet, which allows AI agents to execute on-chain tasks. The wallet introduces a human-machine authorization protocol and a modular skill framework. Its core "covenant" mechanism dynamically generates execution boundaries and termination conditions for each task, enforced at the infrastructure level. The wallet utilizes multi-party computation technology for security, ensuring that even if the AI agent is compromised, the large language model experiences hallucinations, or credentials are leaked, a valid signature cannot be generated alone. The Cobo Agentic Wallet is compatible with LangChain, Open

BroadChain learned that at 10:00 on April 20, according to TechFlow, Kelp DAO's cross-chain bridge based on LayerZero was attacked, with approximately $292 million worth of rsETH stolen, making it the largest DeFi attack event so far in 2026. Affected by this, Aave, SparkLend, and Fluid have frozen rsETH-related markets, and Curve Finance has also suspended its LayerZero cross-chain bridging functionality. Aave saw a single-day withdrawal of $6.6 billion, with USDT and USDC borrowing rates rising to 15%. Additionally, data from Token Unlocks shows that this week, LayerZe

BroadChain learned that at 10:00 on April 20, according to PANews, the Ethereum stablecoin platform Reserve announced that, due to closely monitoring the Kelp DAO attack incident, it has temporarily suspended the minting and rebalancing functions for eUSD and USD3, as well as RSR unstaking, while the redemption function remains open. The platform assessed that if the mainnet rsETH experiences a devaluation of 15.5% to 18.5%, it could potentially trigger bad debt on Aave and affect the USDC collateral on Aave V3. In such a scenario, RSR stakers within USD3 and eUSD might serve as 'first loss capital' to provide protection, but the impact is expected to be minimal, and the existing RSR over-collateralization is sufficient to cover it.

BroadChain learned that at 09:46 on April 20, according to PANews, DefiLlama founder 0xngmi analyzed and pointed out that Kelp DAO faces three handling options in the rsETH incident. Option one is for all users to share the loss, with users facing an 18.5% impairment. If this option is adopted, there are currently about 666,000 rsETH across all Aave deployments. Assuming all chain positions are at a 95% liquidation LTV, their net value would be wiped out, generating approximately $216 million in bad debt. Among this, Umbrella ETH could cover $55 million, the Aave treasury could cover $85 million, leaving a $76 million shortfall.

BroadChain learned that at 09:46 on April 20, according to PANews, the 233-year-old New York Stock Exchange is making a major push into digital assets, planning to build a 7×24 trading platform for blockchain-based securities. This marks a significant transformation driven by distributed ledger technology. Michael Blaugrund, Vice President of Strategy at ICE, the NYSE's parent company, stated that exchanges are entering a new wave of evolution from electronic to digital, and foresee blockchain becoming a crucial carrier for their core business. In action, ICE invested approximately $200 million in cryptocurrency exchange OKX in March this year, valuing the latter at $25 billion.

BroadChain has learned that at 09:30 on April 20, according to TechFlow, Curve Finance announced on April 20 that due to a hacker attack on the LayerZero infrastructure of rsETH, its LayerZero infrastructure has been suspended and will be restored after the root cause is identified. This suspension affects the CRV cross-chain bridging functionality from chains such as BNB Chain, Sonic, Avalanche, Fantom, Etherlink, Kava (chains using native bridges are unaffected), as well as the crvUSD fast bridging functionality (L2 slow bridging is still available). It is also reported that KelpDAO also experienced a leak.

BroadChain learned that at 09:16 on April 20, according to TechFlow, on April 20, DefiLlama founder 0xngmi published an analysis of the bad debt disposal pressure faced by Aave following the Kelp DAO hack and proposed three potential solutions. The first solution involves socializing the losses, where users would bear an 18.5% impairment, potentially generating approximately $216 million in bad debt. Aave's umbrella insurance could cover $55 million, and the treasury could supplement $85 million, leaving a gap of about $76 million. The second solution involves executing a "rug pull" on rsETH holders on L2, which would generate approximately $341 million in bad debt, Arb

BroadChain learned that at 05:16 on April 20, according to CryptoNews, XRP strongly broke through the $1.40 range this week, recording the strongest weekly gain among major cryptocurrencies, with the market still holding bullish expectations for its performance next week. The token climbed to $1.45 at one point this week before encountering resistance and pulling back. Its upward movement showed a controlled, steady climb, suggesting accumulation of funds, but trading volume was about 70% of the weekly average, limiting the certainty of the rise. XRP outperformed Bitcoin and Ethereum over seven days, and its relative strength is meaningful, but volume support remains to be seen. Macro headwinds persist, with the FOMC meeting on April 28-29 approaching, and on Deribit, the price

BroadChain learned that at 05:00 on April 20, according to Bitcoinist, Iran's Foreign Ministry accused the United States on Sunday of implementing an illegal maritime blockade and committing war crimes. This move came hours after US President Trump accused Iran of firing in the Strait of Hormuz, undermining the current ceasefire agreement. Iranian spokesperson Esmail Baghaei posted on platform X, stating that the US blockade of Iranian ports and coastlines not only violates the ceasefire agreement mediated by Pakistan but also contravenes international law and the UN Charter, constituting an act of aggression, a collective punishment against Iranian civilians, and a war crime. Trump told reporters that Iran's firing in the Strait of Hormuz was a 'serious violation' of the ceasefire agreement set to expire on April 22, but he still be

BroadChain learned that at 05:00 on April 20, according to NewsBTC, based on an analysis released by the CryptoQuant platform on April 18, the 'Miner Financial Health Index' (7-day moving average), which measures the short-term financial condition of Bitcoin miners, has currently risen to a reading of 27.7%, approaching the historical critical threshold of 20%. This index synthesizes four core factors: hash price, block rewards, transaction fee share, and total revenue. Historical data shows that during the market cycles of 2019, 2020, and 2022-2023, the index consistently remaining above the 20% level typically coincided with the late stage of the miner 'capitulation phase', where weaker miners are forced to exit the market. Analysis

BroadChain learned that at 00:00 on April 20, according to CryptoNews, former US Treasury Secretary Henry Paulson, who led the 2008 financial crisis bailout, issued a warning that the $35 trillion US debt could trigger a Treasury market crash, urging authorities to formulate emergency 'circuit breaker' plans before a crisis erupts. The transmission path to the crypto market is direct and clear: disorderly bond selling will rapidly tighten US dollar liquidity, and history shows that before Bitcoin's safe-haven narrative solidifies, tightening dollar liquidity first punishes risk assets. The 30-year US Treasury yield has broken through 5%, a level last breached during the inflation surge in October 2023, and after the pre-Great Recession era,

BroadChain learned that at 23:46 on April 19, according to NewsBTC, recent on-chain analysis shows a divergence has re-emerged among Bitcoin investor groups, with institutional and retail behaviors diverging. CryptoQuant's Quicktake analysis points out that Bitcoin spot ETF net inflows are positively correlated with the Coinbase Premium Index (approximately 0.56), indicating synchronized capital inflows and spot demand. However, the key distinction is that institutional buying actually leads ETF inflows, contrary to the common market perception of the opposite logic. The rising Coinbase premium shows U.S. investors are buying back in, becoming a core driver of Bitcoin's price. Yet, the Fear & Greed Index remains
