  • For your first key, choose either a hardware device or a mobile key.

  • For your second key, select another hardware device or add a cosigner.

Note: With all singlesig or multisig wallet setups, it's at the user(s) discretion how to secure and store their physical hardware devices and recovery seed phrases.

Adding A Cosigner (Shared Custody)

A cosigner, a trusted contact like a family member or financial advisor, can be assigned to the vault as a key holder through an email invitation.

  • Set up your recovery key with Theya and first key as described above.

  • For your second key, select 'Invite Trusted Contact'

    • Name the key and invite the cosigner via email.

    • Instructions for setting up a mobile key or pairing a hardware device will be sent to the cosigner's email.

Who Is Shared Custody For?

Collaborative shared custody makes sense in a variety of scenarios. For families, it’s a way to share the responsibilities of self-custody and prevent one person from being a single point of failure. Some may prefer to invite a financial advisor as a cosigner, where a household holds one key, and the other is under professional management. In a similar fashion, a small business might want to split keys between two shareholders or invite a financial manager as a cosigner to reduce internal risks.

Regardless of the situation, Theya is a solution. The modularity of hardware devices for cold storage, mobile keys for convenience, the ability to invite cosigners, and the peace of mind of a recovery key means flexible multisig configurations for shared custody.
