[Backpack Launches Backpack Securities, Integrating Traditional Stocks with Tokenized Securities Trading] According to Deep Tide TechFlow on June 4, as reported by The Block, the crypto exchange Backpack, founded by former FTX employees, has launched the Backpack Securities platform, which integrates traditional stock trading with tokenized stock trading. The platform consists of two interconnected components: 1. A U.S.-regulated brokerage and custody platform that grants investors real stock ownership, along with rights to cash dividends, corporate actions, and integration with systems like ACATS and DTCC. 2. A collaboration with the Solana ecosystem's tokenization protocol Sunrise, enabling users to convert their held stocks into tokenized securities. Initially, this will allow for 24/7 trading on Solana and compatibility with wallets and DeFi protocols, with plans to expand to more blockchains in the future. The related brokerage services are expected to roll out gradually starting in June 2026.
