Before signing, ensure the content displayed on your wallet screen matches exactly what you intend to do. Signing based solely on a string of hexadecimal text is called blind signing; a proper signature request should display the recipient address, amount, and authorized party. Hardware wallets can only guarantee that your private key remains secure—they cannot judge what you’re signing. Spending ten extra seconds to verify before signing is far cheaper than fixing mistakes afterward. #WalletSecurity

The U.S. spot Ethereum ETF experienced a net outflow of approximately $156 million on October 30, marking the fifth consecutive trading day of net outflows. On the same day, Bitcoin ETFs saw a net outflow of about $643 million. While both showed similar directions, Ethereum’s outflows have persisted longer. The single-day amount isn’t large—it’s the five-day continuity that matters: demand failed to absorb the pullback. #ETH

In this Binance incident, the attacker carried out a targeted action: exchanging approximately $325 million in stablecoins for about $285 million in Ethereum. Chain analysis firms believe the motive was to evade freezes by issuers such as Tether and Circle. Once funds are converted into native assets, recovery becomes significantly more difficult—this is also why stablecoins are consistently the first assets frozen following such incidents.

The U.S. spot Bitcoin ETFs experienced a net outflow of approximately $643 million on October 30, ending four consecutive days of inflows. For October, net flows shifted from a net inflow of approximately $128 million to a net outflow of approximately $515 million. This selling occurred following the Binance incident; whether this is a one-time withdrawal or the start of sustained outflows will depend on the first few trading days next week. This is not investment advice.

Ether spot ETFs recorded a net outflow of approximately $1.35 billion in October, with net outflows on 17 of 20 trading days, and another $21 million outflow on the 29th. The distributed outflows throughout the month, rather than a single large redemption, indicate a more persistent issue: not a moment of panic, but sustained weak demand. A shift in sentiment will be confirmed only when flows remain positive for several consecutive weeks. #ETH

EIP-7702 allows a standard Ethereum address to sign an authorization temporarily granting a smart contract the authority to execute transactions on its behalf—enabling batch transactions and gas sponsorship. The risk lies in the authorization itself: signing it means surrendering control of your address to that contract. Hypernative claims the attack code in the Binance incident executed via EIP-7702, though it remains unclear how the signature was obtained. Don’t sign if you don’t recognize the target contract. #EIP7702

The liquidation risk of a lending agreement depends on three parameters: LTV, liquidation threshold, and liquidation penalty. LTV represents the maximum amount you can borrow; the liquidation threshold is the point at which liquidation occurs, with the difference between them serving as a buffer; the penalty is the additional loss incurred upon liquidation. The greater the volatility of the collateral, the wider the buffer should be. Repeated borrowing effectively reduces this buffer. This is not investment advice.

On October 26, Ripple received final approval from the OCC to establish a national trust bank responsible for reserve management, collateral trusteeship, and digital asset custody for RLUSD; issuance remains under the regulation of a trust company in New York State. This type of charter does not permit deposit-taking or lending, with the focus on placing stablecoin reserves and custody under a federal framework. Whether this becomes a norm or an exception will depend on how many other issuers follow suit. #Stablecoin

Galaxy Research’s 13F analysis shows that nine hedge funds and banks reduced their Bitcoin spot ETF exposure by approximately 68,000 BTC, valued at around $5.4 billion. The report attributes this primarily not to bearish sentiment, but to the diminished attractiveness of cash-and-carry arbitrage: the CME basis has declined from an annualized 7.9% to 4.8%, just 0.6 percentage points above the three-month Treasury yield. This is not investment advice. #BTC

Bitcoin dropped to a six-week low of approximately $76,400 on October 30, triggering around $1.5 to $1.6 billion in total liquidations across the network, with over 80% coming from long positions. Much of the downward pressure stemmed from forced liquidations of leveraged longs. When market shocks meet high leverage, price declines are amplified. Your leverage multiple determines whether you can survive a day like this. #BTC
