According to Ledger Insights, State Street plans to launch a crypto custody service next year. Last year, State Street partnered with Taurus to develop custody technology. A survey by State Street in the middle of last year revealed strong customer interest in digital asset custody - including tokenization and cryptocurrencies - but greater interest in cryptocurrencies. State Street Bank's assets under custody (AUC) amount to $46.60 trillion, making it the second largest custodian in the world.
