Automating MPC Wallet Sweeps for Gaian: A Fystack Use‑Case

In the dynamic world of Web3 payments, efficiency and security go hand-in-hand.
Gaian is a Web3-native financial infrastructure that turns any business into a stablecoin-powered neobank, purpose-built for the unique dynamics of Southeast Asia. Trusted by merchants across Vietnam and the broader APAC region, Gaian enables stablecoin payments via QR codes, allowing customers both tourists and locals to pay seamlessly without relying on traditional card networks.

By sidestepping expensive credit‑card fees, Gaian unlocks:

• Seamless checkout for tourists and locals alike
• Reduced transaction costs for merchants who would otherwise avoid card payments
• Instant settlement on Solana and other high‑throughput chains

For non-crypto-native users, Gaian also removes onboarding barriers with Passkey-based authentication, enabling instant wallet creation without seed phrases or browser extensions. Businesses can also integrate through enterprise-grade SDKs and APIs, giving them full control over funds and transactions with minimal effort.

As a result, Gaian is emerging as the payment and financial backbone of Web3 commerce in APAC, bridging crypto-native capital with real-world economic activity.

To support growing volume and ensure operational scalability, Gaian tapped into Fystack’s MPC wallet infrastructure, automating treasury workflows with non-custodial, programmable security. This integration removes manual friction, reduces risk, and ensures every onchain fund movement is secure, efficient, and auditable.

The Challenge: Manual Sweeps & Fragmented Processes

Prior to Fystack, Gaian’s finance team faced:

1. Frequent balance checks every few hours
2. Threshold‑based transfers that needed manual execution
3. Reliance on spreadsheets to track on‑chain funds and fiat reserves
4. Time‑intensive reconciliations when moving assets to exchanges like Binance or Bybit

These manual steps not only distracted from core product developmentthey also introduced latency and room for error.

Fystack’s Automated MPC Workflow

Fystack transforms that cumbersome cycle into a hands‑off, resilient process:

MPC Wallet Onboarding

Gaian uses Fystack’s simple-to-use dashboard to deploy a multi-party computation (MPC) wallet in minutes.
No in-house cryptography team required, just a few clicks.

Continuous Threshold Monitoring

Every hour (configurable), Fystack polls the on‑chain balance. When Gaian’s wallet surpasses its defined threshold (e.g., $50,000), the platform triggers an auto‑sweep.

Secure Fund Sweeps

Funds are routed, via secure MPC signing to Gaian’s exchange accounts for fiat conversion. Signature shares are distributed across distinct geographic nodes, removing single points of failure.

An integrated analytics dashboard provides real-time visibility into wallet activity and sweep volumes, offering full transparency to track growth and optimize treasury operations.

Comprehensive Reporting & Alerts

Automated emails and dashboard alerts update the finance team once sweeps complete. All on‑chain activity and fiat movements appear in one unified view for auditing and compliance.

Real‑World Impact

• 60% Time Savings
  Automating sweeps freed Gaian’s finance team to focus on strategic partnerships and platform enhancements.
• Zero Manual Errors
  Replacing spreadsheets with code eliminated reconciliation discrepancies.
• Scalable Growth
  Gaian now processes thousands of payments per day without adding headcount.
