Over the counter (OTC) trading in Trezor Suite

For users looking to make larger bitcoin and crypto purchases, Trezor Suite (version 25.3.3 and later) supports over-the-counter (OTC) trading—a specialized service for trading large volumes of cryptocurrency. This feature is powered by Mercuryo, a trusted third-party exchange provider.
 
OTC trading is ideal for high-volume transactions, offering deep liquidity and a personalized experience outside traditional exchange environments. It ensures:
 
  • Confidentiality for large trades.
  • Competitive, customized rates.
  • A tailored customer journey for serious bitcoin and crypto investors.
 
This feature aligns with industry standards and expands our capabilities beyond typical Buy and Sell offerings, making Trezor Suite a competitive solution for advanced crypto users.
 
While standard buy/sell options serve casual users well, they don’t accommodate high-liquidity needs. OTC trading fills this gap by offering:
 
  • Access to institutional-grade liquidity.
  • Human-assisted service for large trades,
  • A solution expected in professional-grade wallets, both hardware and software,


Who is it for?

OTC trading is designed for:

 
  • Self-custodial investors using Trezor for full control over their assets.
  • Traditional investors seeking security and performance.
  • Advanced users looking for improved liquidity, personalized support, and better rates for high-volume trades.
 

Whether you're managing your portfolio or making strategic business moves, this feature gives you the flexibility and control needed for substantial transactions.
