Recently, more and more crypto institutions such as Robinhood, Kraken and Coinbase have announced their entry into the tokenized stock market. These platforms are accelerating their layout through different technical routes (such as Arbitrum, Solana, Base) and custody solutions (such as self-custody, xStocks, BitGo, etc.), striving to meet the multiple needs of global users for flexible trading, on-chain transfers and compliance guarantees. With the entry of more participants, the participation of these institutions will promote the tokenization of stocks from the early trial stage to large-scale application, becoming one of the important tracks in the RWA field.
