A few things worth knowing.

Our working sequence has four stages: Discover your needs and risks, Design the custody arrangement, Build it with you, and Rehearse the everyday and recovery procedures. The scope of each stage is agreed before work begins.

You keep your private keys and recovery secrets private throughout the work. The handover includes the documentation and practice needed to operate your setup.

Timing depends on the scope, the people involved, and any hardware or coordination needed. We agree a schedule after the initial discussion, before the engagement begins.

Both. Discovery, design, and most documentation happen remotely. The sensitive steps — hardware initialisation, key-generation ceremonies, recovery drills — are run in controlled conditions, on site where the work calls for it.

Yes. The audit is a written review of what you currently hold: signers, locations, redundancies, single points of failure, and recovery paths. You receive a written review and a prioritised list of improvements.

Start with the free 30-minute consultation. Write a few lines about what you want to achieve and what concerns you; we'll tell you where to start — even if the answer is "you don't need us yet".

We quote after understanding the scope. Your engagement letter sets out the work, fees, and terms before paid work begins. The first 30-minute conversation is free.

Yes — anyone can write to us, and the first conversation is free. We are a small team and take on a limited number of projects at a time, so there is occasionally a short wait, but there is no application or introduction required.

Our consultancy helps you establish your own custody; we do not take possession of your bitcoin. The wallet has a separate role: in its 2-of-3 design you hold two keys and Coinhost holds one recovery key. Our key alone cannot authorize a spend. Consultancy work does not require using this wallet or giving Coinhost a key.

We do not publish your identity or custody details in marketing without your permission. Our Privacy Policy explains how information is used and when disclosure may be required.

Share only what is needed for the conversation. Do not send keys, seed phrases, passwords, or detailed balances through the contact form. The engagement terms define how sensitive working material is handled, delivered, and retained.

No. Our practice is software-agnostic — we set up whatever is right for you, including coordinators and signers we don't make. Coinhost Wallet is an option, never a requirement.

To make these custody principles easier to use: separate signing roles, a documented recovery path, and the ability to operate independently. We are starting with a 2-of-3 model and developing the broader vision of multiple signing models, including 3-of-5.

The 2-of-3 wallet is in a private testnet beta, for test coins only. Join the waitlist for invitations and updates. Mainnet availability will be announced separately; 3-of-5 is planned and not yet available. Read the security model for the design and its limits.

Your two keys can satisfy the 2-of-3 threshold without Coinhost's signature. To use that path, you need saved wallet information, access to both signing keys, and compatible tools. Export and rehearse the route before an outage; a descriptor alone cannot authorize spending. See independent recovery.

A single-signer setup can be appropriate when its backup and recovery procedures fit your needs. If its only key and all usable backups are lost, access is lost. A 2-of-3 setup can tolerate one unavailable key if the other two remain usable, but it adds devices, wallet information, and coordination to manage.

Sometimes. Below a certain threshold, a well-run single-signer setup with a rehearsed backup is reasonable, and we'll tell you so. The case for multisig grows with the amount at stake, the number of people who may need to act, and how long the plan has to survive.

Requirements depend on your location and circumstances. Ask qualified counsel about the rules that apply to you, particularly for a company, trust, or inheritance arrangement. Our work covers custody operations; it does not replace legal advice.
