Crypto and tech updates on July 23: Binance expands bStocks collateral, ZIL and bridge exploits draw scrutiny
A broad set of market, security, regulatory, and infrastructure developments emerged between late July 22 and early July 23. Binance said it will add 10 tokenized bStocks securities as eligible collateral and open margin trading for their related pairs, while Upbit designated Zilliqa’s ZIL as a closely watched asset and suspended deposits and withdrawals after security concerns tied to its wallet or distributed ledger. Zilliqa then disclosed a serious Ledger app nonce flaw affecting native, non-EVM ZIL transactions, saying private keys could be recovered from around five affected signatures. Security incidents also hit B² Network and an AFX-operated bridge in the Arbitrum ecosystem. Elsewhere, Payward said xStocks is expanding tokenized equities beyond U.S. names, Sui launched the Hashi Bitcoin interoperability testnet, BNY Mellon outlined plans for round-the-clock Treasury settlement, and several firms including OpenAI, Alphabet, Revolut, Tesla, and Samsung disclosed major product, spending, or financial updates. The flow also included U.S. legislative movement on the Clarity bill, SEC commentary on on-chain vaults and lending strategies, whale ETH purchases, and fresh market views from Grayscale and Bitwise.
