Mistakes wallets make when designing their on-ramp flows
Common UX flaws in wallets onramping flows.

When it comes to fiat on-ramping, UX is king. And while the UX of ramps providers certainly leave a lot to be desired - UI bugs, mediocre card conversion, clunky Know-Your-Customer processors - there’s also a lot that’s in control of the wallets that integrate these services.
Currency localization
Imagine going to a webstore where products are denominated in the wrong currency. You’ll think “this isn’t for me” and leave.
Yet across the top cryptocurrency wallets, it is common for fiat currencies to not be localized. In fact, in most of the top 10 wallets in the space, I had to manually try and find a way to change the fiat currency.
Some will argue that lack of localization of fiat currencies exists for privacy reasons. But users looking to buy crypto with fiat have to go through Know-Your-Customer (KYC) anyway, which includes filling in their physical address - and often even uploading their passport.
Of course, whether a ramp provider’s services can even be used depends on both fiat currency and country support, so providing a list of ramp options without localisation just results in sending users down dead paths.

Default amounts
In a number of wallets - including leading wallets like MetaMask and Phantom - the default amount displayed is 0. Have you ever wanted to buy $0 worth of cryptocurrency? Probably not.
So how should we think about default amounts?
In my view, the best way to approach default amounts is to use a round number that is higher than the median purchase.
This median changes from country to country, as the average transaction amount in Nigeria, for example, will be lower than in the United States. Therefore, the median should be determined on a country-by-country basis.
The amount displayed should adjust depending on the fiat currency, as at the time of writing every dollar is worth 1577 Nigerian Naira (not a very round number).
Payment method choice
Ask people from the Netherlands, India, Nigeria, the United States and the Philippines which payment methods they want to use to buy crypto, and each will give an entirely different answer.
Yet, the majority of the top cryptocurrency wallets do not support most of the payment methods that will be mentioned.
Other wallets have created flows with ramp providers that support many APMs, without creating a “payment method” selector. This results in the user not being able to compare the difference in price between payment methods.
In addition, any onramp provider that has more than 10 payment methods will be able to tell you how this quickly results in integrations becoming outdated, with the list of payment methods displayed to the user not reflecting what is actually supported (see below).
Payment method localization
For those wallets that do have a range of local payment methods enabled, credit cards are often selected as the default option, despite cards having notoriously bad conversion rates when it comes to buying cryptocurrencies.
Needless to say, it is important to localise payment methods and recommend the best payment methods to users (so important, in fact, that I’ve dedicated a separate article about it here).

Closing thoughts
It is time for us to build flows users enjoy. Next week I will cover on-ramp selection in part 2 of this series.

Onramper Launches Chrome Extension to Compare Crypto Quotes From 30+ Providers Without Leaving the Page
Install in one click and see live quotes side by side in the browser’s side panel, with no analytics or tracking
Amsterdam, October 22, 2026 — Onramper, the fiat-to-crypto onramp aggregator, today launched a Chrome extension that puts crypto buying, selling and swapping in the browser’s side panel, so users can transact while staying on the page they’re already reading. The extension is available now on the Chrome Web Store.
Buying crypto usually means leaving the webpage you are on. People spot a token or an idea, then have to open a new tab and check provider after provider. The Onramper Chrome extension keeps those comparisons in the Chrome Side Panel. Users can see live quotes from over thirty licensed providers in one place, pick the option that suits them and check out. The panel stays open while they browse, so there are fewer steps between spotting something and buying it.
“Crypto has treated the on-ramp as a destination: a separate site, a separate tab, a separate decision. As the industry matures, buying has to happen where people already are, and with more providers and payment methods in every market, comparing them should not be a research project,” said Rick Thomas, Co-CEO of Onramper. “Putting that choice in the browser is how we make a fragmented market simpler to use.”
The Onramper extension is private by default, containing no analytics or tracking. Settings and saved wallets stay in the user’s browser, and cross-device sync is off unless the user turns it on. A single control in the settings menu can erase all extension data.
What users can do with the extension
- Buy crypto with cards, bank transfers and local payment methods
- Sell crypto and cash out to a bank account
- Swap tokens by connecting a wallet in a browser tab
- View prices in their local currency, selected automatically, with one-tap amount presets suited to that currency
- Save up to five wallet addresses under recognizable names and copy one at checkout in a click
Onramper compares quotes from licensed providers and routes the user to the one they choose. Onramper and the selected provider handle identity verification and payment at checkout. Onramper offers 170+ local payment methods, and available providers, payment methods and assets vary by country. The Onramper extension is available now for Chrome.
