Jade for Single-Sig or Multisig | Rich SLP765 — Key Takeaways
Blockstream Jade's blind oracle model means the physical device alone contains nothing stealable — a meaningful architectural difference from secure-element wallets that store everything on-device.
Key takeaways
Jade's blind oracle is a remote secure element — not a custodial risk
Jade's blind oracle is a remote secure element — not a custodial risk
- Encrypted seed lives on Jade; decryption requires PIN + blind oracle secret — neither alone unlocks the wallet.
- If Blockstream's server goes down, users can still access funds by scanning a seed QR directly into Jade.
Jade lets users generate seed words entirely offline — device only computes the checksum
Jade lets users generate seed words entirely offline — device only computes the checksum
- Users roll dice, flip coins, or draw cards to build 11 or 23 words from a lookup table; Jade never touches the entropy.
- Jade calculates only the final checksum word, so the seed generation process requires zero trust in the hardware.
Jade stores your multisig descriptor on-device, enabling wallet recovery after losing a key
Jade stores your multisig descriptor on-device, enabling wallet recovery after losing a key
- In a 2-of-3 multisig, if one key and the descriptor are lost, Jade can push the descriptor back to Sparrow to restore the wallet.
- No other device in the quorum needs to hold the descriptor — Jade alone covers this recovery path.
