WALLET TYPES
eWallet Types We Build for Fintech, Retail and Enterprise Teams
OmiSoft scopes each wallet to the business model — the architecture, compliance layer, and integration surface are defined by your use case, not a template.
CORE FEATURES
eWallet Features That Support Security, Compliance and Scale
Payment systems fail in predictable places — KYC flows that leak, ledgers that drift under retry load, tokenization added after launch as an afterthought. These four areas are where we build differently.
KYC/AML Automation
Integrates Plaid, Persona, and Onfido for document verification and biometric liveness. PEP and sanctions screening via automated watchlist feeds. Risk-scoring rules configurable by your compliance team without engineering involvement.
Ledger & Transaction Engine
Dual-entry PostgreSQL ledger with append-only records and idempotency keys on every state-changing call. Reconciliation runs automatically against BaaS and scheme settlement files — discrepancies surface in the operator dashboard, not in a spreadsheet.
Card Tokenization
EMVCo tokenization replaces the real PAN at issuance — never stored in application state. Apple Pay and Google Pay use the same token infrastructure. The primary account number lives only in the tokenized vault, not in your database, logs, or device storage.
Multi-Currency & FX
Each currency runs in an isolated ledger account — FX decisions are always explicit, never automatic. Real-time rates from OpenExchangeRates, ECB, or a direct bank feed, locked at transaction initiation. Cross-border settlement via correspondent banking or stablecoin rails.

WHAT WE DO
Full-Stack Digital Wallet App Development Services
OmiSoft handles every layer of digital wallet delivery — architecture, compliance integration, mobile development, BaaS configuration, and infrastructure — in a single engagement with one technical team. No handoffs to third-party teams mid-project, no integration debt between front-end and back-end deliverables.
Contact UsPayment Architecture & Ledger Design
The ledger is the financial source of truth for everything the wallet does — every balance, every transaction, every reconciliation event. We design dual-entry PostgreSQL ledgers with idempotency enforcement at the API layer, append-only transaction records, and automated reconciliation logic against BaaS and scheme settlement files. The architecture survives retry storms, network partitions, and third-party provider outages without producing phantom debits or missed credits.
KYC/AML Integration
We integrate identity verification vendors — Plaid, Persona, Onfido, or your preferred provider — into the onboarding flow and configure ongoing transaction monitoring and watchlist screening. This covers biometric liveness checks, document verification, PEP and sanctions list checks, and transaction monitoring rules that your compliance team can tune without touching code. Onboarding flows are calibrated to pass financial regulator review without the kind of friction that collapses conversion rates.
Card Issuance & BaaS Integration
OmiSoft has production integration experience with Marqeta, Galileo, and Stripe Connect. We handle BIN sponsorship coordination, card program setup, spend controls, and dispute management integration. For products outside the US, we scope appropriate regional BaaS partners and manage the integration at the same technical standard. You don't pay for a learning curve.
Mobile App Development (iOS & Android)
The wallet application is built in React Native with TypeScript — a single codebase that produces production-grade iOS and Android applications without sacrificing native performance on either platform. We handle App Store and Google Play submission, biometric authentication integration (Face ID, Touch ID, Android Biometric API), and deep-link routing for payment confirmation flows. Delivery means App Store and Google Play-publishable binaries, not a staging environment handoff.
Compliance & Security Infrastructure
PCI DSS compliance is designed into the architecture from the first database schema decision, not applied as a post-launch checklist. We structure the cardholder data environment to minimize scope using EMVCo tokenization, configure TLS 1.3 for all data in transit, and enforce AES-256 encryption for data at rest. Penetration testing scope, audit logging configuration, and access control reviews are included in the engagement rather than billed as separate line items.

TAILORED SOLUTIONS
eWallet Architecture Options: Closed-Loop, Open-Loop, Embedded and Crypto-Enabled
Architecture choice determines everything downstream: your regulatory footprint, your BaaS relationships, your compliance costs, and how fast you can ship. Getting this decision right at the start is the difference between a product that scales and one that needs to be rebuilt.
Why Teams Choose OmiSoft for Digital Wallet Development
The team building your wallet has shipped a production wallet. Every problem you'll face — a KYC flow that converts but passes regulator review, a ledger that stays accurate under retry load, a BaaS integration that doesn't fall apart during a provider outage — is a problem we've already solved for another client. We bring those decisions to the first architecture call, not to a retrospective six months into the project. The wallet practice sits within a broader fintech software development offering — the same engineering standards apply across the full fintech stack.
FAQ
Frequently Asked Questions
How do I hire eWallet app developers for my project?
The process starts with a technical scoping call where we review your use case, target market, compliance requirements, and preferred BaaS provider. From that call we produce a scoped proposal covering architecture, timeline, and fixed pricing — typically within five business days. Engagements run with a dedicated team of 3–5 engineers depending on scope, with a technical lead as your primary contact throughout. All source code and IP transfers to you at delivery.
How long does it take to build a digital wallet app?
An MVP digital wallet — closed-loop or semi-closed with basic KYC and dual-platform mobile delivery — typically ships in 8 to 12 weeks from contract to App Store submission. A production multi-feature wallet with open-loop card issuance, full KYC/AML stack, and multi-currency support runs 12 to 18 weeks. Timelines depend in part on BaaS provider onboarding cycles, which sit outside our direct control but which we manage actively from day one. We provide a scoped timeline estimate before any contract is signed.
How much does e-wallet app development cost?
E-wallet development starts at $20,000 for an MVP with a closed-loop architecture, basic KYC integration, and iOS/Android delivery. Production wallets with card issuance, full AML compliance, and multi-currency support typically start at $45,000. Enterprise or white-label products are scoped individually based on feature set, BaaS provider selection, compliance architecture requirements, and ongoing support terms. All pricing is delivered as a fixed-scope proposal after a technical discovery session.
What compliance standards does the wallet need to meet?
Requirements depend on the wallet type and target markets. Open-loop wallets require PCI DSS compliance (SAQ D or Level 1 depending on transaction volume) and a BIN sponsor agreement with a card scheme participant. Products serving European users need to address PSD2 strong customer authentication. US-based money transmitter models carry state-level licensing requirements that vary by jurisdiction. We identify the full compliance surface during technical discovery and design the architecture to minimize scope from the start — not after the product is built.
What is the difference between closed-loop and open-loop wallets?
A closed-loop wallet is accepted only within a single operator's network — a brand gift card or a campus payment account. Payments stay inside the system, interchange fees disappear, and the operator controls the full product experience. An open-loop wallet runs on Visa or Mastercard and is accepted everywhere those networks operate — global coverage with the corresponding compliance overhead: BIN sponsorship, card program management, ongoing scheme compliance. Semi-closed wallets work across a defined partner network without requiring the full compliance structure of an open-loop product.
Can you integrate KYC/AML into the wallet?
Yes. We integrate document verification and biometric liveness via Plaid, Persona, Onfido, or your preferred vendor, and configure ongoing AML monitoring including PEP and sanctions screening. Transaction monitoring rules are set up through the vendor's dashboard and tunable by your compliance team without engineering involvement. KYC flows are calibrated to pass financial institution and regulator review. We also document the full integration for your compliance team's audit requirements.
Who owns the source code after delivery?
The client holds full ownership of the source code and all intellectual property delivered during the project — application code, ledger schema, API layer, and any custom integrations. You receive the full codebase, not a licensed deployment. You can modify it, extend it, or hand it to a different team without restriction. This is written into the contract before work begins.
