Crypto payment cards have emerged as a critical bridge between digital assets and mainstream commerce, enabling users to spend cryptocurrencies (or crypto-backed fiat) at millions of merchants globally via Visa/Mastercard networks. Yet, few users realize that most crypto firms do not initially issue their own cards—instead, they rely on BIN sponsorship (Bank Identification Number sponsorship), a foundational partnership model borrowed from early fintechs like Revolut and Monzo. This research article explains the mechanics of BIN sponsorship, analyzes the unique challenges crypto firms face in leveraging this model (e.g., stricter regulatory scrutiny, cross-border compliance, and crypto-specific risk management), and proposes a phased framework for crypto companies to launch and scale payment cards. By aligning BIN sponsorship strategies with regulatory maturity and user growth, crypto firms can balance speed-to-market with long-term control over their payment infrastructure.
