What if your IBAN was a Bitcoin address? We've created it. Here's how it works.

A service/protocol that maps bank identifiers (IBANs) to Bitcoin addresses to simplify payments and improve user experience between banking and crypto systems. It describes the architecture, resolution, and operational risks.

Practical comment: Consider UX design and accounting reconciliation: mapping identities simplifies adoption but adds error vectors; prioritize automatic reconciliation, validations, and dispute mechanisms for integrations with legacy systems.

⚖️ Personal note
#DYOR — I personally lean more towards privacy and decentralization, but the concept and what's being developed here is quite interesting and caught my attention.
