I support the sentiments of @brico84 @abduraman & @Iksolon and @SPAddict25 shared an excellent article on recent hack.
When I first got involved with this project the Ledger Hardware Wallet integration was on the roadmap and this did excite me. I saw this ‘upcoming’ feature vitally important to securing assets. In my opinion Security and Privacy go hand-in-hand.
Now with that said, I do not think the QR code solution is a good long term solution (no offense to @Horus87, I do thank you for offering this idea). My issue with the QR code solution is it introduces a point of failure that is NOT industry standard practise. It introduces a separate hardware device that needs to be secure and safe. The beauty with having a ledger, is if my ledger device breaks. I can buy another one and restore my 24 word seed phrase and viola, I’m back in business.
IT MAY NOT BE TOO MUCH WORK

Since the PRV token is a BEP-20 token, this means Incognito could piggy back off the existing “Binance Smart Chain BNB” Ledger App for signing transactions ( https://support.ledger.com/hc/en-us/articles/4405365395857-Binance-Smart-Chain-BNB-?docs=true ) See below excerpt from the page above…
Hence, there is no need for Incognito to develop and maintain it’s own stand-alone Ledger App. If this proves to be possible then Incognito could take a similar approach to THETA Network.
The THETA Token is an ERC-20 token.
When accessing Theta’s Web Wallet - https://wallet.thetatoken.org/unlock/cold-wallet (see below)
I can use a Ledger Hard wallet to sign-in and sign transactions. To do this I use the Ethereum App on the Ledger device.
Hence, a similar approach could be taken with the Incognito Web Wallet Extension, have it connect to Ledger’s “Binance Smart Chain (BNB)” App.
Here’s the Github for Theta Web Wallet - https://github.com/thetatoken/theta-wallet-web
I’m not a developer but I thought this may help the amazing Incognito Dev team see how Theta built their Ledger integration. It may help to fast track a similar solution.
Hey, @duc @Jared & @Jayce_Nguyen, can someone please bring this up with the Incognito Dev Team on your next call?
