Cold Storage for Cryptocurrency

Learn how our cold storage for cryptocurrencies works.

SWP offers offshore cold storage for cryptocurrency wallets and keys. Clients can rent a safe deposit box housed within our Class III UL-rated vault in the Cayman Islands to store their wallets and keys for only $500 USD per year.

How Cold Storage Works

Making A Deposit

    Option A) We can arrange a FedEx shipment of your wallet and/or key to our Cayman Islands facility on your behalf. For $150 USD, we will provide you with a pre-paid FedEx label, a fire-retardant bag as well as a tamper evident bag to protect your wallet and/or key while in transit.

Once the package arrives at our facility (within 24-48 hours), an SWP representative will deposit the unopened tamper evident bag containing your wallet and/or key into your safe deposit box. We will then FedEx you two safe deposit box keys (you can elect to store one key at our facility for future use).

    Option B) Clients can hand carry their wallet and/or key to the Cayman Islands by commercial flight or cruise ship. Once you arrive at our facility, you can make the deposit into the safe deposit box.

Making A Withdrawal

    Option A) If you wish to make a withdrawal from your safe deposit box, you (or an Authorized Representative) will have to be present with your safe deposit box key in hand. You can make a withdrawal by appointment.

    Option B) You can elect SWP to make the withdrawal on your behalf (we will require one of your safe deposit box keys). We will arrange a FedEx shipment of your wallet and/or key to your physical address on file, or to an alternative cold storage location for a cost of $100 USD.


As a non-financial institution, SWP has no wealth reporting requirements to either the Cayman Islands government or any foreign government or tax authority.


Safe deposit boxes are not audited.


You have the ability to visit and inspect your safe deposit box holdings by appointment.

You have the right to store other valuables in your safe deposit box, including precious metals, jewellery, documents, etc.
