Inspiration
The project was inspired by the State Bank of Vietnam (SBV) strategic roadmap, which identified 2025–2026 as the pivotal "explosion period" for Open Banking in Vietnam. Recognizing the regulatory push to connect financial institutions with third-party service providers, we saw an urgent need for a secure, scalable, and intelligent platform that could bridge the gap between traditional banking and modern fintech innovation.
What it does
Wealthriver serves as a specialized gateway and intelligence layer within the Open Banking ecosystem. It enables seamless data exchange between banks and third-party providers while ensuring strict regulatory compliance. The platform provides users with consolidated financial insights, automated risk assessment for lenders, and personalized wealth management suggestions, all powered by real-time data integration.
How we built it
We built Wealthriver using a microservices architecture to ensure high availability and modularity. The core components include:
API Gateway: A secure interface designed to handle standardized Open Banking protocols.
Data Processing Engine: Utilizing Python and specialized financial libraries to normalize disparate data sources.
Security Layer: Implementing OAuth2.0 and advanced encryption to protect sensitive user information.
Mathematical Modeling: We integrated risk-scoring algorithms using Bayesian inference to evaluate creditworthiness:
P(A∣B)= P(B) P(B∣A)P(A)
and weighted factor analysis for financial health:
Score= i=1 ∑ n w i ⋅x i
Challenges we ran into
The primary challenge was data fragmentation. Different financial institutions in Vietnam use varying standards, making interoperability difficult. Furthermore, navigating the evolving regulatory landscape required constant adjustments to our compliance engine. Balancing "openness" with "absolute privacy" was a technical tightrope, requiring us to implement zero-knowledge proof concepts to verify data without exposing raw sensitive details.
Accomplishments that we're proud of We are incredibly proud of successfully aligning Wealthriver with the Financial Services Track requirements set by Shinhan Bank. Achieving the technical benchmarks necessary to gain priority access to the Global Shinhan InnoBoost program was a major milestone. We also successfully demonstrated a prototype that can aggregate data from three different simulated banking environments in under two seconds.
What we learned
We gained a deep understanding of the Vietnam Open Banking Ecosystem and the critical role of the SBV in shaping future finance. We learned that technical excellence is only half the battle; building trust through transparent security protocols and clear value propositions for both banks and end-users is equally vital. We also sharpened our skills in building "compliance-by-design" software architectures.
What's next for Wealthriver
Our next step is to move from prototype to a pilot program within the Shinhan InnoBoost incubator. We plan to refine our AI-driven financial advisory features and expand our integration capabilities to include non-traditional data sources (such as e-commerce and utility payments) to provide a more holistic financial profile for the unbanked and underbanked populations in Vietnam.
