Multisig key service

Enogtjue acts as a professional cosigner in a 2-of-3 multisig setup. You control the funds with your two keys; we hold only one of three keys and can never move Bitcoin alone. This is not a custodial service, but an additional layer of security and a continuity plan for your assets.

What is multisig?

2-of-3 keys
Three keys are created, but only two are needed to sign a transaction. You hold two keys; Enogtjue holds one.
No custody
Enogtjue can never move your Bitcoin alone. You retain full control, and our key provides an additional approval.
Additional security
Even if one of your keys is compromised, nobody can move the funds without approval from a second key.
Continuity plan
If you can no longer use your keys, heirs or trusted people can work with Enogtjue to recover access.

Why choose Enogtjue as your cosigner?

  • BankID verification – We verify your identity with BankID before signing, preventing unauthorised cosigning requests on your behalf.
  • Offline PSBT signing – Our key is stored offline. We sign PSBTs (Partially Signed Bitcoin Transactions) without the key ever touching the internet.
  • Canary Bitcoin monitoring – We monitor the multisig address and notify you immediately if unexpected transactions are detected.
  • Norwegian company – Enogtjue is a product of Schjønhaug AS, registered in Norway and subject to Norwegian law, providing legal predictability and access to complaints procedures.

How it works

  1. Setup by video call – We walk through the setup together, generate keys and configure your multisig wallet.
  2. Test transactions – We send and sign test transactions to verify everything works correctly.
  3. Metal plate backup – All keys and configuration are backed up on durable metal plates resistant to fire and water.
  4. Signing when needed – Contact us when you need a cosignature. We verify your identity with BankID and sign the transaction offline.
