Trade Privately, Settle Instantly
The problem Cosmos solves
**The Problem It Solves
**
- In today’s financial ecosystem, cross-border settlements and institutional transactions face multiple challenges:
- Lack of Privacy: Traditional banking rails expose sensitive transaction data, creating risks for institutions and clients.
- Slow Settlement: Cross-border transfers can take hours or days, delaying liquidity and operational efficiency.
- Compliance Complexity: AML/KYC regulations require sharing sensitive data across multiple institutions, increasing risk and overhead.
- Fragmented FX & Netting: Private FX rates and interbank netting are difficult to execute without revealing positions or exposing strategies.
**How ZISN Helps
**
ZISN – Zcash Institutional Settlement Network addresses these pain points:
Private Settlements
-
Uses Zcash shielded transactions to hide transaction details while maintaining integrity.
-
Prevents sensitive information leakage between institutions.
Instant Cross-Border Transfers
-
Transactions are processed immediately on the settlement layer, simulating real-time payments.
-
Eliminates waiting times common in traditional rails like SWIFT.
Zero-Knowledge Compliance
-
AML/KYC is verified via Mina zk-proofs, allowing institutions to prove compliance without exposing customer data.
-
Simplifies regulatory reporting while protecting privacy.
-
Private Netting & FX
-
Netting between institutions can be executed privately using Arcium mock netting, reducing liquidity needs.
-
FX conversions can be simulated via Aztec/Fhenix private rates, preventing front-running and exposure.
Who Can Benefit
-
Banks: Private settlements between branches or subsidiaries without revealing sensitive data.
-
Fintechs & Remittance Services: Instant, private cross-border payments for customers.
-
Custodians & OTC Desks: Shielded settlement across multiple chains and assets.
-
Regulators (Demo/Proof-of-Concept): Ability to verify compliance proofs without seeing raw transaction data.
Challenges I ran into
Challenges I Ran Into
During the development of ZISN — Zcash Institutional Settlement Network, we faced several hurdles, mostly related to privacy simulation, integration, and free tooling limitations:
- Integrating Privy Wallet Login
Challenge:
Privy Wallet login was easy to set up for individual users, but our system needed institutional identity simulation.
We had to map a single wallet login to a “mock institutional account” with multiple roles.
Solution:
Created a hash-based mapping from the wallet public key → institutional ID.
Added a role field in our local JSON database to simulate bank, fintech, or custodian roles.
This allowed the dashboard to display different features depending on the role.
- Simulating ZK Proofs (Mina)
Challenge:
Implementing actual zkSNARK/zk-STARK proofs is complex and time-consuming, not feasible in a hackathon.
Solution:
Created mock zk-proof JSON objects for KYC, settlement, netting, and FX.
Each mock proof included realistic fields (proof type, issuer, hash, timestamp) to make the demo believable.
Ensured frontend could display “proof verified” status for all actions without real ZK computation.
- Shielded Transaction Simulation (Zcash Layer)
Challenge:
We couldn’t use real Zcash shielded transactions on mainnet for free.
Solution:
Implemented dummy shielded transactions with random TX hashes.
Stored them in local JSON/Supabase for demonstration.
Added UI feedback like ✅ “Shielded Settlement Completed” to make it feel real.
- Private Netting & FX Simulation
Challenge:
Arcium and Aztec/Fhenix require complex privacy-preserving computations.
Solution:
-Created mock netting calculations using local dummy data.
-FX rates were randomly generated but realistic-looking, with a “zk-proof” field in JSON.
-This allowed us to demonstrate functionality while keeping everything free and hackathon-friendly.
