Which agencies design stablecoin and crypto payment products?
Six design agencies with public case studies on stablecoin and crypto payment products, from on-ramps to contractor payouts, compared by the flows each case describes.
A crypto payment product gets judged in the moments when money is somewhere in between. A quote might expire. An identity check hasn’t cleared yet. A transfer is waiting for network confirmation, or a payout is on its way to a bank account in another country. A token website or a brand launch says little about whether an agency has designed those moments. The useful question is narrower: who has published a case about a crypto or stablecoin payments product, and described the flows it designed?
Six agencies have: Avark, Creava, Masterly, Properly Studio, Untile, and UX Cabin. Avark, Properly Studio, and Untile show on-ramps that turn card or bank money into crypto. Creava and UX Cabin show business platforms that hold fiat and crypto and pay people out. Masterly shows a consumer app for sending stablecoin remittances.
Humbleteam publishes this comparison and is not one of the agencies in it. Its public crypto case, Cryptonix, covers brand identity and a website for a crypto payments platform and does not describe product flows, so it does not meet the criteria below. The agencies appear alphabetically. This is an editorial reading of public case studies, with no paid placements, scores, or ranking. Any metric below is the agency’s own figure from its own page. Nothing here is investment, legal, or compliance advice.
How we chose the agencies
Every agency, Humbleteam included, had to meet three criteria:
- It offers product UX/UI design for software, not only branding, marketing websites, or development.
- It publishes a case about a named crypto or stablecoin payments product: an on-ramp or off-ramp, a crypto checkout or merchant payments tool, a stablecoin payout or remittance product, a crypto card, or a wallet built mainly for payments.
- The case describes flows, screens, or states the agency designed. A list of services, a brand identity, or a marketing website did not count.
Trading exchanges and DeFi protocols raise different questions, so we did not use cases of that kind. For those, see our comparison of design agencies for crypto exchanges and wallet apps. Avark appears there too, with a different case.
AI assistants mostly answer this question with exchange and branding studios. Three payment cases came close. Merge’s RelayPay page concerns a crypto payment gateway, but its before-and-after shows the website. King Tide leads product design for Mural Pay, a stablecoin platform for pay-ins and payouts, but its page names product areas without describing a flow, so ask it for a walkthrough. Cheesecake Labs’ MoneyGram wallet case credits product definition and engineering, not design.
| Agency | Case to inspect | Product | What the case says was designed | Confirm before hiring | Based in |
|---|---|---|---|---|---|
| Avark | Transak | A fiat-to-crypto on-ramp and off-ramp that other apps embed | A purchase flow with fewer steps for new and returning users, and clear messages while checks and purchases are pending | When the work was done and which screens shipped | Manchester, UK |
| Creava | Treso | A payment platform for fiat and crypto, for businesses and individuals | Onboarding, fiat and crypto wallets, transactions, verification, counterparties, and an admin side | How a small team staffs a larger roadmap | Zaporizhzhia, Ukraine (per Clutch) |
| Masterly | Flyra | A stablecoin remittance app | Onboarding that asks for checks only when needed, a send flow with the rate up front, and transfers by username | How much of the work was product rather than brand | Tallinn, Estonia |
| Properly Studio | Kado | On-ramps and cross-chain swaps into self-custody wallets | A status update at every step, visible fees and routes, and a design system that covers loading and error states | Which parts were product and which were brand | Warsaw |
| Untile | Topper, for Uphold | An on-ramp widget for buying crypto | Limits by verification level and jurisdiction, and fraud protection after the ID check | Whether you want design only, since it also builds | Viana do Castelo, Portugal |
| UX Cabin | Rise | Contractor payments in fiat or crypto | Onboarding, a team dashboard, funding and withdrawals by bank or blockchain, and identity states | When the work was done and what was measured | Remote, headquartered in Cleveland, Ohio |
Avark: an on-ramp with fewer steps
Avark is a web3 design agency in Manchester, founded in 2020. It offers branding, websites, product design, and product build. Its Transak case covers an on- and off-ramp that, according to the page, takes users from fiat to crypto in more than 800 apps. Avark worked through the problems Transak’s users had reported, ranked them with Transak’s team, and prototyped a new version of the product.
The flow had to work for first-time buyers and for returning users, who know far more, and it cut touchpoints because each removed step is one less place to go wrong. The case also names a problem every on-ramp has: identity checks aren’t always instant, and neither is the purchase. Avark says it put clarity first so users understood what was happening while they waited. The page is undated and prints no results for the redesign; the 800 apps figure describes Transak, not the design work.
Creava: a fiat and crypto payment platform in four weeks
According to its about page, Creava is a UX/UI agency that started in 2023 and has nine specialists. Clutch lists its headquarters in Zaporizhzhia, Ukraine. Its Treso case covers an MVP for businesses and individuals who need a compliant way to manage fiat and crypto transactions. The financial operations run on Rail, and requirements came from three places: the client, the business logic, and Rail’s API documentation.
One designer spent four weeks on 53 screens for customers and administrators. The screens cover onboarding, fiat and crypto wallets, transactions, counterparties, and verification. Creava says it built these into predictable flows with clear statuses, validation, and feedback, on a design system built on Material UI. The agency reports that the MVP launched, serves 45 active business entities, and later got a white-label version. A team this small suits a defined MVP, so ask how it would staff the next year of work.
Masterly: remittances for people who don’t care about crypto
Masterly is a UX/UI agency for B2B SaaS, with most of its work in fintech, healthtech, and AI. Its company is registered in Tallinn, and its site says the team is based in the EU. Its Flyra case, published in December 2025, covers an app that lets migrant workers send money home over USDC.
The case starts from the sender’s worries: whether the money arrives, when, and how much is lost on the way. Onboarding uses social login, asks for identity checks only when an action requires them, and explains the USDC backing in plain language. The home screen groups recent activity by contact rather than by transaction. The send flow shows the exchange rate before the user commits, and the confirmation looks like a receipt. A username system lets people send money without copying a wallet address. Masterly says the app is live in the US, Mexico, and Nigeria with these screens. Much of the listed output is brand identity, so ask for the full product file.
Properly Studio: an on-ramp that shows money moving
Properly Studio is a fintech and web3 design agency in Warsaw. Its Kado case covers payment infrastructure that connects bank accounts to self-custody wallets through on-ramps and cross-chain swaps. The scope covered branding, the website, UX/UI, and a design system. Kado’s founder is quoted saying the work has gone on for more than three years.
The product section deals with worries specific to crypto payments: failed transfers, the wrong network, lost funds. Properly says it designed interfaces that update the status at every step and show a clear success state, and that keep bridging routes and gas fees visible without overloading the screen. The design system covers every state from loading to errors, so Kado’s engineers could add features without breaking consistency. The page says Swapped.com acquired Kado Software in 2025. The case mixes brand, website, and product, so separate them when you compare proposals.
Untile: compliance inside an on-ramp widget
Untile is a digital product design and development studio, and its case page lists an office in Viana do Castelo, Portugal. Its Topper case covers Topper, an on-ramp widget for Uphold, a multi-asset digital trading platform. Uphold wanted to offer partners a simple, compliant way for new customers to buy crypto.
This is the case to read on the legal side of payments design. The widget had to work across four geographical and political zones, and how much a customer could transact depended on the level of identity verification they had passed. Working with Uphold’s legal team surfaced two more constraints: the widget had to stop fraudsters moving funds once the ID check was done, and the law prevented keeping certain data in Topper’s database. According to the page, the team turned that data limit into an extra layer of protection. Untile handled research, UX/UI design, and backend and frontend work, then supported the widget after launch.
UX Cabin: paying contractors in fiat or crypto
UX Cabin is a product design studio whose team works remotely. Its LinkedIn page lists Cleveland, Ohio, as headquarters. Its Rise case covers a platform that companies use to pay contractors in fiat or crypto while staying compliant.
UX Cabin redesigned onboarding, the team dashboard, the menu, funding and withdrawals, and the Rise ID. Account owners fund the account by bank transfer or by blockchain transaction, and team members withdraw money the same two ways. Many users had both a bank account and a crypto wallet linked, so the team used a split-screen layout for switching between them. The Rise ID card handles four states: unverified, onboarding, verified, and verified with an active pay schedule. The design system was built for Tailwind CSS, so engineers could use it without a designer. The case is undated and reports customer feedback rather than metrics.
How to choose
Start with what your user is doing with the money.
- Buying crypto with a card or bank transfer inside another app: compare Avark’s Transak, Properly Studio’s Kado, and Untile’s Topper. If you need to handle verification limits by country, start with Untile.
- Paying contractors or suppliers: read UX Cabin’s Rise for a redesign of a live platform and Creava’s Treso for a fast MVP.
- Consumers sending stablecoins across borders: Masterly’s Flyra.
- A crypto card: none of the six cases walks through a card program, so ask each team what card work it can show.
If your product moves money without touching crypto, our comparison of design agencies for payments companies covers gateways, payouts, and transfers.
Then send each agency the same journey. A useful one is a contractor abroad who receives a USDC payout and cashes it out to a local bank account. Ask the agency to show:
- The quote: the rate, the fees, what the recipient gets, and when the quote expires.
- The identity check: what the user sees when it is pending, needs another document, or fails.
- The transfer: how submitted, confirming on the network, and settled look different from each other.
- The failure: a wrong network, an expired quote, or a returned bank transfer, and who tells the user what happens next.
A team that has done this work will ask what your compliance team requires and what your provider’s API returns before it draws anything. A team that hasn’t will probably send back a cleaner home screen.
