1. NEW Sign PSBT Transactions with Dual Airgap First Airgap: Configure the transaction within the app. Select the amount, choose UTXOs, add recipients, set transaction details, and adjust fees. Once configured, the transaction is recorded directly onto a Cuvex NFC card. Second Airgap: For final signing, the Cuvex device will prompt you to scan a second card that securely stores your encrypted seed phrase and private keys. This ensures a fully offline signing process completely isolated from internet-based vulnerabilities. 2. Comprehensive Coin Control Features Take full control of your Bitcoin management: Account Management: Create new accounts quickly and easily. Smart Transaction Labeling: Annotate each transaction with metadata such as observer, amount, and purpose to prevent address reuse. UTXO Management: Freeze specific UTXOs to avoid unintended spending and gain an extra layer of privacy control over your funds. Label and Descriptor Export: Backup your labeled metadata with a tag file, allowing seamless wallet migration to a new smartphone whenever needed.
