Manna Wallet + Branta Guardrails: Self-Custodial Bitcoin Payments Now Show Verified Merchant Details

Branta Guardrails has integrated with Manna Wallet to display verified merchant logos and details inside the self-custodial wallet before users send Bitcoin payments. The privacy-preserving feature uses open-source, zero-knowledge proofs to authenticate merchant payment addresses without exposing invoice or address data. The integration aims to reduce human-error and man-in-the-middle risks, improve user confidence in immutable Bitcoin payments, and streamline merchant onboarding via existing tooling (BTCPay plugin, Zaprite). A live QR-demo with wallets like Manna and Arkade is available. Market impact: this UX/security improvement could raise on-chain payment adoption and merchant acceptance over time, supporting broader Bitcoin utility and potential incremental demand, though it is a product/UX development rather than a near-term price catalyst.
