Air-gapped wallet that does not need to connect to an online device.
Multiple cryptocurrency support.
Keystone (formerly Cobo Wallet) was founded at the height of Bitcoin’s 2017 bull market by Discus Fish (CEO) and Changhao Jiang (CTO). The company is headquartered in Beijing with offices in Shanghai, Xian, and Seattle. Fish founded F2Pool, a mining pool company, and Jiang is a former Facebook engineer. Their company provides the needed tools for individuals and institutions to custody their cryptocurrencies. Keystone emphasizes their long-term approach in security, reliability, and convenience for their customers. They address all major storage markets with products like: Keystone companion app (an interface to view your funds when your hardware device is not connected), Keystone Essential (a cold storage wallet that does not connect to devices with internet access), Keystone Pro, and Keystone Ultimate. The main differences between the 3 Keystone device packs are the accessories included in each.
Along with security, Keystone’s mission is to be a one-stop shop for everything crypto by supporting 9 different coins, 700 tokens, and providing access to an integrated DApp store (decentralized applications that run on distributed computer networks).
With the Keystone Essential pack (base model pack), the device comes in a box sealed in plastic. Make sure that the packaging is not tampered with or opened. Inside the package, you will find the following:
Keystone versus Coldcard
If a user is interested in using an air-gapped feature with their hardware wallet to add an extra layer of security, they may find Keystone to be more straightforward than its competitors.

The pros of using the Keystone are:
The cons of using Keystone are:
The recovery seed is a set of 24 words that need to be written down in sequential order. Recovery seeds are a method for saving your private key in a readable format rather than using a very long series of numbers and letters. Whoever has access to your recovery seed can gain control of your wallet. It is imperative to keep it safe and private.
Keystone supports: BTC, ETH, BCH, DASH, DCR, EOS, ETC, IOST, LTC, TRON, XRP, XZC, DOT, KSM, TCFX, ERC20, TRC20, and EOS Tokens. Here is a list of supported assets.
As long as you have the seed phrase written down on a non-digital material, you may import that seed phrase onto a new device. By doing so, you will gain back access to all your funds.
A watch-only wallet is required to be used with a Keystone device because it is only to be used as a storage device for the private keys. The user may only view their balances and transactions with the phone app while the Keystone device is used only for verifying and signing transactions.
Keystone supports importing 12/18/24-word recovery phrases generated by any BIP39 wallet. Note: Keystone supports segwit addresses for BTC, which require less fees than legacy addresses for the same transaction.
PSBT is an emerging standard for "Partially Signed Bitcoin Transactions" or BIP 174. The Keystone device uses PSBT with the attached camera to scan addresses and never connect to another device. This added security layer ensures that the Keystone device is much less likely to be compromised from an infected device.
