Stable Coin Tracking and Analysis

Stable coins represent one of the most successful innovations on blockchain to date with billions in transactions happening every day in #USDT and #USDC alone. Blockchain based stable coins offer cheaper transfers and more transparency and are set to replace much of the outdated traditional banking system in both international trade and consumer transactions. At Whale Alert we track and analyze stable coin transactions across blockchains and use this data to create the most complete and up to date live and historical data set of international monetary traffic in the world with more than 90% of stable coin transactions tracked.
