The only #Bitcoin hardware wallet not susceptible to physical key extraction is the Blockstream Jade. Jade uses a virtual secure element (blind oracle) so your seed is not stored on the device. You can also set up your own blind oracle or run it stateless with SeedQR (like a SeedSigner). By not having a physical secure element, Jade can remain fully open-source and easily DIY-able.

Looking for a fun weekend Bitcoin project? In light of Blockstream Satellite's sixth anniversary, I wanted to highlight an overlooked feature: the ability to broadcast data into space with Lightning. In the demo, I use the new Greenlight-powered Blockstream Green wallet (public beta available soon, inside sources say next week). When sending the message, I used the transmission page on the Blockstream site, but there are other frontends like
Blockstream Satellite | Send Broadcast
Send Blockstream satellite transmissions and view transmission data.
 or P-38 (great for private, encrypted messaging), if you don't have access to the API directly via the blocksat-cli.

There's been some buzz around #stablecoins lately, given their increased usage in the Global South. Using only your phone, here are two simple ways to get Tether USDt on Liquidβ€”a Bitcoin L2 with multi-asset support and confidential transactions that is compatible with Lightning. By using Liquid, you further hyperbitcoinization and the #Bitcoin ecosystem and avoid relying on inferior alts with backward incentives like #TRON or #Ethereum. First, if you don't already hodl L-BTC, you'll need to either a) bridge BTC to L-BTC (aka peg-in) or b) use a swap tool like Boltz or SideShift to get some. Both apps used in the video have native peg-in capability and non-custodial Liquid wallets built-in, but I'll use Boltz and #BlockstreamGreen to move from LN-BTC to L-BTC in the second example to mix things up. 1. SideSwap A registration-free mobile app with Tether USDt and EURx stablecoins available via atomic swap or limit order. Fees: 0.6% (swaps), 0.1% or 500 sats (orders), 0.1% (peg-in), Liquidity: ~0.75 L-BTC (swaps) 2. TDEX A DEX protocol with Tether USDt, L-CAD, and Bitcoin-backed stablecoin FUSD (Fuji Money) available via atomic swap. Fees: dependent on market makers (swaps), no additional fee (peg-in), Liquidity: subject to mmkr Note depending on your buy size, jurisdiction, desired privacy, or stablecoin needed, you may want to explore other platforms that have Liquid, including: Bitcoin Reserve Bisq Bitfinex BTSE BTCTurk Bull Bitcoin Hodl Hodl Peach Bitcoin Sideshift
The new Lightning-capable #BlockstreamGreen works flawlessly (even in beta), receiving sats from Wallet of Satoshi and then zapping a friend on #Nostr. #Bitcoin, Liquid, and Lightning in one, non-custodial, privacy-focused wallet. Open beta coming soon! Green's Lightning integration works via Blockstream's Greenlight under the hood, which does most of the heavy lifting, while the Breez SDK acts as a facade and LSP service. Don't miss out on other upcoming experimental features by signing up for Green's beta program: https://help.blockstream.com/hc/en-us/articles/14884124911385?ref=blog.blockstream.com
