Our platform supports Trezor and Ledger wallets as signing devices

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
Learn more about how Unchained secures its keys here
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
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
Feel more confident when you travel with your hardware wallet, knowing that it’s only 1/3rd of a quorum, so your assets are still protected by advanced authentication procedures.
