I remember Bitcoin Safe received grants from OpenSats from some time ago.


Just to be sure, are you representative of Bitcoin Safe or just one of Bitcoin Safe user?


It's probably because they have several feature for multi-sig, including built-in chat over nostr.

I gave op a merit which is a step towards being able to post images.

at op please let us know how you are connected to the bitcoin-safe wallet


if you can establish a legitimate connection with the wallet I will test one out for you.

I have a pc that I can use.

I highly recommend to read and understand the Unofficial list of (official) Bitcointalk.org rules, guidelines, FAQ.

Multiple consecutive posts within short time frames (less than 24h) as you did are not allowed according to rule #32. It's OK to bump a topic after a minimum of 24h. Delete your own most recent older bumps if you re-bump a topic.

There's no need to answer different users in separate posts. You can always edit your last post and insert quotes of other users you want to respond to by using the Insert Quote links in the Topic Summary below the reply entry box (I'm refering to posting using a desktop browser, not sure if the Insert Quote links are available while posting from a mobile phone).

I like this wallet brings to bear the Nostr layer to transfer PSBT data between cosigners, which makes the whole process more secure for them. That said, one question still remains open for me. Does Bitcoin Safe utilize MuSig2 to aggregate all signatures or does it still rely on the native multisignature schemes?

When creating transactions, Bitcoin Safe takes into account the address categories, to avoid linking categories. Categories can however be edited, and new categories created that apply to all wallets. This feature comes to enhance the label and allow better multi-wallet management.

The creation of hotwallets is enables for all testnet, hot seeds are supported. It's disabled for mainnet for many reasons: https://bitcoin-safe.org/en/knowledge/hardware-signer-only/




Thanks for your appreciation on the Chat&Sync feature over nostr. The protocoll is open source and can be easily implemented by other wallets if needed.

For the multisig, we use the native schemes, since this is the best tested, and allows 1 round signing.


Thank you!

Bitcoin-Safe allow to fully manage wallet descriptors, making it easy to customize settings. Another unique feature is the Chat&Sync that allow signers to remotely communicate and coordinate transactions signing without the need to be in the same physical location.

Label synchronization across computers, collaborate PSBT signing, and so much more. The full list of features is listed in our website https://bitcoin-safe.org/en/features/readme/ Check it out and let us know how you like it.

Test Bitcoin Safe and see if you like it, let us know how you compare with Electrum and Sparrow, and if you feel we can do something differently, we are here to hear your feedback and suggestions.

PS: Version 1.5.0 is coming out soon which makes the UI feel super organized also for multiple wallets.

In this case it's the tough call to decide which option is better. On one hand aggregated signatures offer better privacy. On the other hand  they require  more complex setup where all co-signers must use MuSig2 compatible wallets ^{including hardware wallets, if any are involved}. Given that MuSig2 is still not widely adopted your choice seems to be the most practical for the current situation.

It depends on BDK, if direct connection via RPC will be possible. However RPC has many downsides, such as it will always be difficult to setup and slow to sync.
A better and faster solution is Compact Block Filters, which I'm aiming to support as soon as possible. 

Yes, in the future this might change, and if support for frost/musig is added in BDK, I'll reevaluate it again.

I have developed a protocol https://github.com/andreasgriffin/bitcoin-nostr-chat?tab=readme-ov-file#protocol that uses encrypted nostr messages (NIP17) to exchange messages between the different computers (using an extended version of BIP-329 ).  Satsigner.com is adopting this protocol too, such that you will have cross-wallet label synchronization and PSBT exchange.

Are there any plans for supporting new hardware wallet Trezor Safe 7?
I can see older Trezor versions are already supported, along with devices from other manufacturers.
Another support I would like to see is for Satochip cards, if possible.
