Don't invest unless you're prepared to lose all the money you invest. This is a high-risk investment and you should not expect to be protected if something goes wrong.

UK-based team. Human support.

Secure storage.

All cryptoassets are held in independent, named cold-storage wallets. Each client's holdings are segregated for clarity, control, and reporting. Designed to reduce operational risk and meet institutional due diligence and reporting expectations.

  • 100% Deep-Freeze Cold Storage

    Deposit direct to air-gapped cold storage. Assets are kept offline.

  • Named, segregated custody

    Funds are held in named, segregated addresses. We use individual private keys to maximise security.

  • Direct-to-cold deposits

    Your addresses are cold from day one, assets are never 'waiting online' to be swept.

  • Same-day withdrawals

    Request a withdrawal and receive assets the same day (subject to checks and cut-offs).

  • Trade without operational friction

    Execute when you need to, including OTC support for larger orders and broader asset coverage.

  • Designed by experts

    Built by a team with deep experience across cryptography, security, and finance. Our team has been active in Bitcoin and crypto since 2010 and operating Solidi since 2015.
