How it works
The user funds an account at a regulated fiat-to-crypto venue (a centralised exchange, broker, or dedicated on-ramp provider) by ACH transfer, SEPA, debit card, or wire. The venue holds the deposit, executes the conversion at market rate plus a spread or fee, and credits the user’s wallet with the equivalent crypto. KYC verification is required at virtually every regulated ramp.
Example
You wire $10,000 to Coinbase. Two business days later the funds settle. You convert into USDC at no fee, or into BTC at a 1.5 percent spread. You can keep the crypto on the platform or withdraw it to your own wallet. To off-ramp, you sell back to USDC or fiat on the same platform and request a bank withdrawal, typically settling the same or next business day in supported jurisdictions.
Why it matters
Fiat ramps are the gating bottleneck between the traditional financial system and crypto. They determine where retail users can enter the market, what KYC they go through, and how much fee they pay. Limited fiat-ramp access in certain countries leaves users dependent on peer-to-peer markets, OTC desks, or stablecoin proxies. The on-ramp is where regulation is most likely to bite first; pick a provider regulated in your jurisdiction.
