Las Vegas-based Prime Trust, which offers crypto infrastructure tools, raised a $107M Series B, following a $65M Series A in July 2021

Context & Ripple Effects
Prime Trust's $107M Series B lands a year after its Mercato Partners-led $64M Series A, doubling down on the same bet: selling regulated financial-services APIs — custody, compliance, payments rails — to fintechs and digital-asset companies rather than serving consumers directly.
It also lands near the top of a funding wave for trust infrastructure: Paxos had just closed a $300M Series D at a $2.4B valuation in April 2021, and Las Vegas neighbor Fortress Blockchain Technologies would raise a $22.5M seed weeks after this round. What makes the story worth tracking is how it ends — Prime Trust later halted deposits and withdrawals and filed Chapter 11 with liabilities of $100M–$500M against assets of $50M–$100M, meaning this raise financed a business whose liabilities ultimately outran its assets.
First-order effects
- Prime Trust gets a $107M war chest to scale its API-based custody and financial infrastructure for fintech and digital-asset clients, going head-to-head with far better-capitalized Paxos in the regulated-trust layer.
Second-order effects
- Fortress Blockchain Technologies' $22.5M seed two months later shows the B2B Web3 infrastructure niche filling fast, forcing every player to compete on regulatory breadth and integration depth rather than custody alone.
Third-order effects
- Prime Trust's eventual Chapter 11 — liabilities of $100M–$500M against assets of $50M–$100M — illustrates the structural risk of venture-scaled trust businesses: when client assets are held in trust, a balance-sheet failure is a counterparty event for every fintech plugged into its APIs, not just an investor loss.
The trend: Venture capital concentrated heavily in regulated trust-and-custody infrastructure during the 2021 crypto boom, and the sector is now consolidating around whichever players can survive their own balance sheets.
