What is a crypto on-ramp?
An on-ramp is a service that lets you turn government money, such as dollars, into crypto. Centralized exchanges, payment apps and crypto ATMs are common on-ramps.
What it means for you
On-ramps are usually regulated businesses that ask for identity documents (KYC) and keep records linking your name to the purchase and to the addresses you withdraw to. Compare the total cost, not just the fee line: card purchases and ATMs often add a markup to the price itself.
How it works
Converting dollars into crypto needs a business that can take bank or card payments, which is why centralized exchanges are the main on-ramps; the Federal Reserve notes decentralized exchanges cannot take dollars directly. Even buying a dollar stablecoin usually goes through this route: issuers often mint new coins only for approved business customers, so individuals buy on exchanges, in the secondary market. Treasury notes centralized platforms are still needed for many trips between dollars and crypto, and they carry anti-money laundering obligations. That is where identity checks and the link between your name and your withdrawal addresses come from.
