Off-ramp

An off-ramp performs two distinct functions: acquiring the asset you dispose of, and getting money onto an account in your name. The second part is a payment rails problem, not a blockchain one, and it is generally the harder half.

It is also where anti-money-laundering regulation concentrates its requirements, since it is the border between the two systems. A service converting without identity checks beyond very low thresholds is not doing so for simplicity: it is operating outside the applicable framework.
