On June 10, TrueUSD announced on Twitter: “TUSD mints via Prime Trust are paused for further notification.” They offered no further explanation. TUSD is the fifth largest stablecoin by market capitalization.The decision may have been related to insolvency rumors surrounding Prime Trust, a US-based fintech company. On June 8, BitGo announced a non-binding letter of intent to acquire Prime Trust.After the announcement, the TUSD stablecoin dipped as low as $0.9951. This is a seemingly small deviation from the $1 peg, but in the stablecoin world, such small variances can be serious.
