Banking and Payment Apps Built for Real Financial Lives
Splicity designs and engineers digital banking platforms and payment wallets that handle real transaction volumes securely. Clients launch faster, reduce fraud exposure, and build lasting user trust.
Audit-ready from launch
Every data flow, access log, and transaction record is structured to satisfy regulatory audits without retrofitting your architecture later.
Lower fraud surface
Built-in velocity checks, device fingerprinting hooks, and anomaly flags reduce unauthorized transaction rates before you reach significant user scale.
Faster time to market
Pre-integrated modules for KYC, ledger, and notifications cut estimated build time, so you can begin onboarding real users ahead of schedule.
FinTech App Development
The outcome we're after
Most fintech projects stall not at the idea stage but at the compliance and integration stage. Connecting to payment rails, satisfying RBI or international regulatory requirements, and building fraud-resistant flows demands specialized experience that generic software teams rarely have.
Splicity approaches fintech builds with a compliance-first architecture review before a single line of product code is written. We map your regulatory environment, select battle-tested payment gateways and banking APIs, then design data flows that satisfy audit requirements without slowing the user experience.
The result is a production-ready wallet or banking application that clears security reviews, processes payments without silent failures, and gives your compliance and ops teams the reporting visibility they need to run the product confidently from day one.

FAQ
Frequently asked questions
Which payment gateways and banking APIs do you integrate with?
We work with Razorpay, Cashfree, Stripe, and open banking APIs across India, Southeast Asia, and Europe. For core banking, we have integrated with Finacle, Mambu, and custom CBS solutions. We recommend the right stack based on your geography and transaction profile.
How do you handle RBI compliance for a digital wallet product in India?
We structure the product around RBI Prepaid Payment Instrument guidelines from the architecture phase, covering KYC tier limits, transaction caps, and fund settlement timelines. We also prepare the technical documentation your legal team needs for licence applications.
Can you build both the customer app and the merchant or ops dashboard?
Yes. A complete fintech product typically needs a consumer-facing mobile app, a merchant acceptance layer, and an internal operations dashboard for reconciliation and support. Splicity scopes and delivers all three as a coordinated product, not separate projects.
What security standards does your fintech development follow?
We follow PCI-DSS Level 1 design principles, OWASP Mobile Top 10 guidelines, and encrypt all sensitive data at rest and in transit using AES-256 and TLS 1.3. We also conduct threat modelling and recommend third-party penetration testing before any public launch.
