Simplicity and No Harm to Security

Managing Bitcoin keys is a usability and security trade-off. Operating robust technology, we built our modular product for uncompromising service levels and simple integration.

Custody solutions

Accessible Custody

Simple and secure Bitcoin custody from manual to programmatic access—on your own terms.

OvalCreated with Sketch.

Terminal with Access Keys

Knox account administrators can use the terminal with personal access keys as a secure interface to their private custody account and initiate transactions to our air-gapped facilities. Web apps introduce security holes.

Cold Storage API

Programmatic access is critical to our advanced users or models with high throughput like exchanges and trading desks. Bespoke integrations become a breeze.

Hybrid Model

Get a simple interface, secure access, and custom governance controls afforded by our Terminal and Access Keys, with the convenience of programmatic access through our Cold Storage API.


Don’t Give in Control

Knox is incapable of arbitrarily moving client holdings, without explicit client requests made prior. All account approval quorums are bespoke, and chosen by clients with specific policies including subsets of authorizers, transaction thresholds, and daily rate limits—per wallet.


Simple Pricing with Flexibility

All segregated customer accounts are expected at minimum to hold $1M of assets under custody (AUC). All fees can be adjusted based on projected AUC, and monthly transaction volumes.

Custody Base Fee — Range

30 - 100 bps

Insurance allocations are dedicated per client account with certificates issued by Marsh.

Custody Blended Fees — Bespoke

Adjusted on total AUC, cold storage withdrawal frequency, and programmatic access limits.
