Prostrive builds custom e-wallet apps for FinTech startups, payment providers, banks and platforms that want their own digital wallet, as part of our payment software development services. Our e-wallet app development services cover the full product: the customer app on iOS, Android and web, the ledger that keeps every balance accurate, the back office your team runs on, and the integrations with banks, card issuers and KYC providers. You own the code and the IP.
Let's talkMost e-wallet application development starts with the app. We start with the money: a double-entry ledger that balances after every top-up, transfer and refund, and reconciles with what your banking partner reports. The screens come after that.
Your licence model shapes that ledger. Holding funds as an e-money institution, working through a licensed partner or running a closed-loop wallet each calls for a different architecture, so we settle it with you before development starts.
Securing the licence itself is for you and your legal advisers; we build to the model you choose.
Most e-wallet projects start from one of the types below, and many combine two. Each type changes who can top up, where the balance can be spent and whether it can be withdrawn as cash. That decides the licence you need and how the ledger is built. Whichever type you choose, we deliver the wallet on iOS, Android and web from one shared backend.
A closed-loop wallet holds a balance that can only be spent with one brand, such as a retail chain, a transport operator or a gaming platform. We build the top-up flows, the loyalty and rewards logic, and the redemption rules. Because funds stay inside one network, some closed-loop wallets fall outside e-money rules, but refunds and withdrawals still need careful design.
Let's talkSemi-closed wallets let users pay a defined network of partner merchants without cashing the balance out. We build the merchant onboarding, the settlement to each partner, and the transaction limits the network needs. This model suits marketplaces, mobility services and loyalty coalitions.
Let's talkOpen-loop wallets work like a payment account: users top up by card or bank transfer, pay wherever the wallet is accepted and withdraw to their bank. We connect the wallet to payment gateways, card schemes and banking rails, and design the onboarding and authentication a regulated stored-value product demands.
Let's talkMulti-currency wallets hold balances in several currencies and convert between them at a quoted rate. We build the currency accounts, the quote and conversion flow, and a ledger that tracks each currency separately, so cross-border users and businesses always see accurate balances.
Let's talkP2P payment apps let users send money to each other by phone number, contact or QR code, split bills and request payments. We build instant transfers between wallets, payouts to bank accounts and the notifications that confirm each step for both sides of the transaction.
Let's talkMerchant wallets let businesses accept wallet payments in-store and online, through QR checkout, payment links and recurring billing. We build the merchant onboarding, the checkout flows and the settlement, and refund reporting a finance team needs.
Let's talkAn embedded wallet adds a balance to a product you already run, such as a marketplace, a gig platform or a SaaS tool, so users can get paid, hold funds and spend them without leaving it. We integrate the wallet into your existing app and backend, and connect it to the licensed partner who holds the funds.
Let's talkCrypto-enabled wallets hold digital assets alongside fiat, with on- and off-ramps between the two. We build custodial and non-custodial wallets, connect exchange and custody providers, and design for MiCA when you serve EU users. Our team built FiatGate, a white-label platform for branded non-custodial crypto wallets and exchanges.
Learn moreAn e-wallet product is three systems that have to agree at all times: the app your customers use, the back office your team runs and the integrations that move real money in and out. We build all three on one ledger, so a balance in the app always matches the records your operations team and your banking partner see.
Onboarding with identity checks, top-ups by card or bank transfer, transfers, QR payments, withdrawals, transaction history with digital receipts, push notifications, and virtual or physical cards. Logins and payments use strong customer authentication under PSD2, such as biometrics on a registered device.
Your operations team manages users, KYC status, fees, transaction limits, refunds and disputes from one back office. It includes reconciliation against your banking and payment partners, reporting for finance and a full audit trail, with role-based access to personal data in line with GDPR.
We connect the wallet to payment gateways, banking partners, card issuers, open banking APIs and KYC providers, plus AML screening and transaction monitoring services. Card data is tokenised through the processor, so it never sits in your database, and your PCI DSS scope stays small.
Choosing an e-wallet app development company comes down to whether it understands money movement, compliance and your business, not just mobile apps. Here's what working with us looks like in practice.
We've built payment products that move real money. For Globus Payments, an EMI-licensed provider in London, we built the API integrations with financial institutions and the compliant client onboarding. For Axys, we built the card infrastructure, including crypto top-up of the card balance.
PSD2, PCI DSS, KYC, AML and GDPR shape the first architecture decisions, not a checklist before launch. That keeps late rework off your roadmap and gives you documented controls to show your banking partner, acquirer or auditor.
In a custom build, you own the code and the intellectual property under every collaboration model. There's no platform licence to renew, and no vendor you're tied to when you change providers or bring development in-house.
If you need a standard wallet live quickly and won't compete on features, a white-label platform can be the better route, and we'll tell you so. Custom development pays off when the wallet is your product, or when it has to fit a platform you already run.
Our developers join your standups and Slack channels and work as part of your team. Western on-site management in our hubs, plus cultural workshops and communication training, keeps quality and communication at the level you'd expect locally.
Scale the team up when you add a card programme or a new market, and down again after launch. There are no long-term contracts in any engagement model, and your team can start within weeks, not months.
Every e-wallet project runs through the same four steps. The first one takes out most of the risk: by the time we design screens, the fund flow, the licence model and the compliance scope are already on paper.
We choose technology for accuracy under load. Transaction services run on Node.js and Python, with Kafka and Redis Streams moving events between the ledger, notifications and reporting in real time. Customer apps are built in React Native or Flutter for iOS and Android, and in React for web. Docker and Kubernetes on AWS let the platform scale with your transaction volume.
How you work with us depends on the team you already have and how clearly your wallet is defined. In every model, you own the code, and there are no long-term contracts.
Dedicated Teams work only on your product and report to you. This suits a wallet that keeps growing, where knowledge of your fund flows, providers and compliance requirements builds up inside the team over time.
With Team-as-a-Service, you set the goals and priorities while we manage the team day-to-day and own delivery, oversight and quality control. It fits when you want e-wallet expertise without managing developers yourself.
Project-Based Development takes your e-wallet from discovery to launch as one complete build against a defined brief. It suits founders and payment companies who know what the wallet has to do and want one team accountable for it.
Your e-wallet team combines backend engineers who've worked on ledgers and payment integrations, mobile and web developers, designers who know regulated onboarding flows, and QA engineers who test money movement end to end. Every team works under Western on-site management and follows the same standups, tools and code reviews as your in-house developers.

Read the case studyTell us what your wallet needs to do, who holds the funds and where you're launching. In a discovery call, we talk through the fund flow, the build or white-label question and the team you'd need, so you leave with a clear next step.
The cost of developing an e-wallet app depends on scope rather than a standard price. The main drivers are the wallet type, the number of currencies and payment methods, card issuing, the compliance scope under PSD2, PCI DSS and KYC, and how many providers the wallet connects to. Adding a wallet to an existing platform also costs less than a standalone product. We scope the cost once the fund flow is mapped.
How long it takes to build an e-wallet app depends on the wallet type, the integrations and the licence model, so we don't quote a fixed timeline upfront. A closed-loop wallet with one top-up method moves faster than a multi-currency wallet with cards. After discovery, you get a realistic plan for your MVP, and the team itself can start within weeks, not months.
An e-wallet app is safe when security is designed into it from the start. That means strong customer authentication under PSD2, tokenised card data so no card numbers sit in the app's database, encryption of data in transit and at rest, identity checks at onboarding and AML screening of transactions. A double-entry ledger with regular reconciliation also makes errors visible before they turn into losses.
An e-wallet app is a digital wallet that stores money or payment details in a phone app or online account, so users can pay, transfer and receive funds without cash or physical cards. Some e-wallets hold a stored balance, others store linked cards and bank accounts, and many do both. Behind every e-wallet app sits a ledger that records each balance and transaction.
Whether you need a licence to launch an e-wallet depends on who holds the funds. In the UK and EU, issuing stored value usually requires an e-money licence, or working through a licensed partner such as an e-money institution or a bank. Some closed-loop wallets fall under exemptions. Licensing is a question for your legal advisers; we build the e-wallet around the model you choose.
A white-label e-wallet platform launches faster when you need standard features and won't compete on them. A custom e-wallet makes sense when the wallet is your core product, has to fit an existing platform, or needs flows a platform doesn't support. With custom development, you also own the code and pay no platform licence fees. We weigh both routes with you during discovery.
You own the code and the intellectual property of your e-wallet app when we build it for you. That applies to every collaboration model: Dedicated Teams, Team-as-a-Service and Project-Based Development. You can hand the e-wallet over to an in-house team or another partner at any point, without depending on us to keep it running.
Choose an e-wallet app development company on evidence, not on its portfolio of generic apps. Ask which payment products it has shipped, how it designs the ledger and reconciliation, how it handles PSD2, PCI DSS and KYC, and who owns the code afterwards. A good partner will also tell you when a white-label platform suits your wallet better than a custom build.
Yes, we can add an e-wallet to an existing app or platform. We integrate the wallet with your current backend and user accounts, add the ledger and payment flows, and connect a licensed partner if you don't hold funds yourself. Marketplaces and gig platforms often take this route to pay out sellers or workers and let them spend their balance inside the platform.
An e-wallet app needs onboarding with identity checks, top-ups and withdrawals, transfers between users, a real-time balance, transaction history and notifications. Most also add QR payments, multi-currency accounts or virtual cards. Behind the app, your operations team needs a back office for users, fees, limits, refunds and reconciliation, which first scopes often underestimate.
Yes, an e-wallet can hold crypto next to fiat currencies, with on- and off-ramps to convert between them. That adds a custody decision (custodial or non-custodial), integrations with exchange and custody providers, and MiCA obligations for EU users. We built FiatGate, a white-label platform for branded non-custodial crypto wallets and exchanges, so we know where those integrations get complicated.
