POWERFUL SECURITY THROUGH A SIMPLE PROCESS

KEYS

Our platform supports Trezor and Ledger wallets as signing devices

Users upload extended public keys (xpub) to their account

Unchained never has access to a user’s private keys

If single keys are ever compromised, our platform will facilitate creating new keys and/or transfering funds to a new vault or another safe destination

How Unchained secures its keys

VAULTS

Users create a vault with uploaded xpub keys to derive a secure 2-of-3 multisig address

Every time a withdrawal or transfer occurs, a new multisig address is derived from the vault keys

Users are provided with the information necessary to move funds outside Unchained’s system as a backup fail safe, including redeem scripts and BIP32 paths

Users can create as many different vaults as they need or would like

WITHDRAWALS, TRANSFERS & SIGNING

All transactions, including withdrawals and transfers, are on-chain & require cryptographic keys to sign

Only users can initiate transactions. Once initiated, a user will use their own key(s) to sign. If they control 2-of-3 keys, they can sign without any involvement from Unchained.

For certain vault types and thresholds, Unchained will validate the identity & intent of a user prior to cosigning

Once two keys have signed a valid transaction, the user has the responsibility to broadcast
