According to CoinMeta, Michael Saylor, the chairman of MicroStrategy, recently proposed a multi-tier digital finance architecture that officially designated USDT stablecoins as the main transaction gateway for the ecosystem for the first time. This architecture distributes assets across a range of currencies, from the volatile Bitcoin to stable fiat payment tools. Saylor stated that this new model is aimed at addressing the limited transactional utility of Bitcoin and integrating USDT to meet the market's demand for fast, daily payments. Strategy has also developed new financial engineering products, including semi-stable fixed-income credit instruments STRC and hybrid tokens SR-STRCUSX that combine the stability of fiat with debt market returns.
