Understanding multisig and the 3 different keys

What is a Multisig?

Multisig stands for multi-signature. It’s a type of digital wallet that requires more than one key to approve a transaction.

In a 2-of-3 setup:

• 3 keys exist

• Any 2 are needed to approve a transaction or recover access

• This protects you if one key is ever lost, stolen, or compromised

It’s like a safe that needs two keys to open, you control both, and we only help if one goes missing.

The 3 Keys in Oasis Vault

Key	Who holds it	What happens if you lose it
Mobile key	You	Funds recoverable with Ledger + Oasis
Ledger key	You	Funds recoverable with Mobile + Oasis
Oasis recovery key	Oasis

Why this setup works?

• You hold two keys (mobile + Ledger), so you can transact anytime without our involvement.

• We hold the third, but only for emergencies, like you losing your Mobile key or Ledger.

This means:

• You’re never dependent on Oasis to move your crypto

• But you’re also never lose your crypto if you make a mistake

How are the keys protected?

• Your Ledger key is stored in the secure hardware, offline

• Your mobile key is encrypted, stored in your mobile and iCloud (if you chose to) and can only be decrypted with your passkey

• The Oasis key is securely stored with our proprietary set up

We never have control over your assets. You stay sovereign at all times.

Common Questions

Q: Can Oasis ever move my crypto without me?

A: No. Our key alone can’t do anything. It’s just one of three - and two are always required.

Q: Why not just hold one key and let Oasis handle the rest?

A: That’s not self-custody. If we could move your funds on our own, it would defeat the whole point.
