According to data from Omni Explorer, Tether ($USDT) minted $250 million worth of USDT tokens today, 6/25/2018. Per the company's website, Tether is "always backed 1-to-1, by traditional currency held in [their] reserves" so 1 USDT is always worth 1 USD. The move faced a backlash from critics as the stablecoin lacks official public audits, which undermines the company's legitimacy and its claims about the backing.
