Manna Wallet + Branta Guardrails: Self-Custodial Bitcoin Payments Now Show Verified Merchant Details
Branta, a Bitcoin security company, recently announced integration with Manna Wallet, a self-custodial payments app. Users will now see the logos and company details of merchants they make payments to on Manna before they make a payment, letting them make the purchases with confidence. “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.
Demo The Technology
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.
Users in this example might be tempted to grab the recipient address from their blockchain history, which attackers have dusted with the poisoned address, tricking the user. While poison address attacks are more difficult in Bitcoin, other ways to trick users exist. Human error is also a possibility that experienced Bitcoin users know well, sometimes joking about it online.

Branta Guardrails works as a “side channel” to authenticate the connection between sender and recipient. Merchants can join the growing network of Branta merchants and platforms, and integrate their technology via a wide range of Bitcoin invoicing software already supported, such as a BTCpay server plugin and Zaprite’s suite of merchant tools.
A live demo can be tested with some of the wallets like Manna and Arkade. Scanning supported QR codes brings up the merchant logo on the user wallet and clickable link to verify recipient details. Phil Geiger, advisor to Branta, showcasing that demo, X.com saying it “Makes me feel much more confident before sending an immutable bitcoin payment!”
