In 2026, mitigating Man-In-The-Middle is standard practice.
Sending #Bitcoin with certainty is now a choice.
When sending irreversible transactions, it makes sense to be certain you are sending to the right place.
Branta is the last line of defense for #Bitcoin payments.
The Bitcoin ethos is “Don’t trust, verify,” yet, with #bitcoin transactions, it is commonplace to “trust” without verifying.
Trusting at the point of transaction is how Bitcoin gets lost.
Never trust, verify instead. It’s the Bitcoin way.
