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.

Helio Partners with Onramper to Power Unique Card to Stablecoin Payments for Global Merchants
Onramper’s industry-leading aggregator will localize payment methods for merchants looking to accept instant stabelcoin payments.

Helio, a leading crypto checkout app used by over 6,000 merchants and millions of users, has advanced the adoption of crypto payments by offering a faster, more affordable alternative to traditional methods.
To date, Helio has processed over $1.5 billion in transactions and integrates with leading digital platforms, including Shopify, where it powers the popular Solana Pay plugin. Now, the company is launching a revamped payment flow that enhances the onboarding experience for new users that don’t already have a crypto wallet when completing purchases with stablecoins such as USDC.
Now when Helio users select “Pay with Card”, they’re guided through a localized payment method selection screen tailored to their region powered by Onramper’s industry leading on-ramp aggregator and smart routing engine. Users can quickly fund a virtual crypto wallet tied to their email by purchasing USDC and easily complete their payment to the merchant. This seamless fiat-to-crypto flow unlocks valuable new commerce use cases for merchants, including instant settlement from credit card purchases (instead of next day settlement), zero chargeback risk, seamless iGaming deposits via cards, global support for high risk payments and more.
Stablecoin usage continues to rise – recent reports show retail usage increased by 35% in 2024 as consumers increasingly turn to stablecoins for e-commerce to avoid banking delays.
“Collaborating with Helio to enable stablecoin payments is a major step toward bringing crypto commerce to Web2-native users,” said Thijs Maas, CEO of Onramper. “Our aggregation engine delivers localized on-ramps and payment methods, making it easier for users to check out.”
Onramper accepts 130+ payment methods and enables users to purchase crypto across 190+ countries. This extensive geographic coverage is complemented by sophisticated routing engines that recommend the best conversion for users in real-time – maximizing users’ odds of a successful transaction and ensuring they receive the most crypto for their fiat.
"Helio is known as the market leader in native crypto payments, offering low fees and instant settlement. With the integration of Onramper, we’ve expanded backwards compatibility with the traditional financial system. This allows Helio merchants like Liquid Brokers and Bizcuits to accept instant card payments in over 130 countries through seamless fiat to stablecoin onramps. This results in increased sales for our merchants and a faster, smoother checkout experience for customers at Helio-powered stores. It’s a big step toward making crypto payments as seamless as traditional ones, especially for those new to crypto or looking to top up quickly." said Stijn Paumen, CEO of Helio.
“At Bizcuits, we support trading brokers and prop firms with operational solutions, including payments infrastructure. We integrated Helio for card-to-crypto payments because of its seamless experience, transparent pricing, and global reach.
