Fiat On-Ramp
The path from conventional money into crypto — the step where most first-time Web3 users stop.
An on-ramp converts fiat to crypto: card or bank payment in, tokens into a wallet out. It is the most failure-prone step in Web3 onboarding, because it stacks every hard thing at once — KYC, a card payment with high decline rates for crypto merchant categories, a network and token choice the user does not understand, and a wallet address that must be exactly right.
Most products integrate a third-party provider and hand the user off. That transfers the compliance burden and none of the responsibility: from the user's point of view your product sent them somewhere else and something failed. Designing the handoff — saying what is about to happen, what the fees will be before they commit, and what to do when the card is declined — is the difference between an on-ramp that works and a support queue.
Fees have to be shown before the commitment
Provider spread, network fee and card fee are often disclosed only on the final confirmation, where an advertised “$100” has become $91 of tokens. That is the single most common complaint about on-ramps and it is entirely a presentation decision.
In practice
A wallet integrated a third-party on-ramp behind a “Buy crypto” button with no context. 62% of users who started never completed; the largest single drop was at the provider's KYC step, which appeared without warning. Adding a short screen naming the provider, the documents needed and the all-in fee before the handoff took completion to 71%.
Where teams get it wrong
- Handing off to a provider with no explanation of what the user is about to face.
- Disclosing the full cost only at final confirmation.
- No guidance when a card is declined — common for crypto merchant categories.
- Asking the user to choose a network before explaining what the choice does.
- No visible state while a purchase settles, which can take minutes.
