👋 Hi Product Hunt! We are thrilled to launch Paranoid Qrypto: BTC AIRGAP BRIDGE. This is our new, open-source tool designed for securely broadcasting Bitcoin (BTC) transactions from a completely air-gapped or cold wallet setup. 🔒 Why did we create this? In the world of crypto, security is everything. Many tools can expose your private keys to online risks. We built a solution that guarantees your keys stay 100% offline, from start to finish. The entire process runs client-side in a single, auditable HTML file. You can check out the full open-source project on our GitHub. 💡 How it works: Fetch Info Online: Use the bridge to get the necessary UTXOs and current network fee rates for your transaction. Sign Offline: Transfer this information to your air-gapped wallet (using a QR code) or manually and sign the transaction securely. Broadcast Securely: Use another QR code to move the signed transaction hex back to the online tool and broadcast it to the Bitcoin network. Your private key never touches an internet-connected device. We are eager to hear your thoughts and feedback. Please let us know if you have any questions, suggestions, or features you would like to see in the future. Thanks for your support
