BitGo is reportedly in talks to acquire crypto custodian Prime Trust, pending regulatory approval. Prime Trust offers developer tools and APIs to crypto companies, including custody, payment rails, compliance, liquidity, and settlement. Last year, the Las Vegas-based firm raised $107 million in Series B funding, but recently lost clients including Binance.US. The SEC lawsuit against Binance.US mentions a "Trust Company B," leading to speculation that it could be Prime Trust.
