Whether you hold assets for customers or rely on a custodian to hold your own, the custody agreement decides who owns the assets and how fast they can move. We draft and negotiate custody and wallet services agreements covering segregation, key management, withdrawals and liability. Whether a custody model triggers money transmission, trust or other licensing is fact-dependent, and we flag it; each engagement is a flat fee, quoted before we start.

Mistakes we help you avoid

The ones we see most often, and catch before they cost you.

  • Avoided

    Using language that transfers title to the custodian when customers expect to remain owners

  • Avoided

    Accepting liability caps that are tiny relative to assets under custody

  • Avoided

    Leaving withdrawal timing and suspension rights open to the custodian's discretion

  • Avoided

    Describing a wallet as non-custodial when your system actually controls the keys

Custody & Wallet Services Agreement: questions founders ask

At a minimum, it should cover ownership of the assets, segregation, how withdrawals are authorized, liability for loss and what happens in insolvency. It should also address forks, airdrops and unsupported assets. The specific terms depend on whether you are the custodian or the client.

In a custodial wallet, the provider controls the private keys and can move assets on the user's behalf. In a non-custodial wallet, only the user controls the keys. The distinction affects your contract terms and can affect regulatory analysis, which is fact-dependent.

It depends on the custody agreement, how assets were held and the law that applies to the custodian. Clear title and segregation language helps, but it does not by itself determine the outcome in a bankruptcy. We draft with insolvency risk in mind and explain where uncertainty remains.

Custody can raise state money transmission, trust charter or other licensing questions depending on your activities, your customers and where they are located. The analysis is fact-dependent. We flag those questions in your structure and draft the contracts; we do not issue licenses.
