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

Manna Wallet integrated Branta so users see merchant logos and details before making Bitcoin payments. The wallet verifies that payments go to the intended merchant, providing a link for users to confirm authenticity. Branta’s open-source, privacy-centric software uses zero-knowledge proofs to avoid learning payment addresses or invoice data while still guaranteeing the client-to-merchant connection is genuine. Branta Guardrails is designed to reduce risks such as human error and man-in-the-middle attacks. It addresses misdirection risks seen in other blockchains, including “poisoned address” schemes that mimic recipients from prior payment history. Guardrails authenticates sender-recipient connections through a side-channel approach.

"“Bitcoin payments give users anxiety. Every single time,” said Adam Simecka, CEO of Manna in the announcement, a key fact that to him, explains why Bitcoin adoption is lagging."

"“Manna now automatically ensures your payments are going to who they say they are with Branta. When you pay a Branta integrated business, you will see their details and a link to verify yourself. Don't trust. Verify.” Simecka, announcing the integration."

"Branta's software is open source and privacy-centric, using zero-knowledge proofs to avoid knowing anything about the payment addresses or invoices involved, while guaranteeing the connection between client and merchant is authentic. “We went way out of our way to make sure the process met high standards of privacy.” Kieth Gardner, co-founder of Branta told Bitcoin Magazine."

"Branta's Guardrails service was designed to eliminate risks like human error or man-in-the-middle attacks between users and merchants in Bitcoin. Such attacks of this sort have become very popular in other blockchains, such as Ethereum, called “poisoned address”, created to mimic recipients that a client makes regular payments to."
