In the dynamic world of Web3 payments, operational efficiency and security go hand‑in‑hand. Gaian , a leading QR‑code payment network powerd by stablecoin in Southeast Asia, tapped into Fystack’s wallet infrastructure for Web3 startups to automate its treasury operations, removing friction, reducing risk, and driving growth. Who Is Gaian? Gaian empowers merchants across Vietnam and Southest asia countries to accept stablecoin payments simply by scanning a QR code.

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

Its popularity within the Solana community has surged, but rapid transaction volumes and manual fund‑management workflows were becoming bottlenecks.

The Challenge: Manual Sweeps & Fragmented Processes

Prior to Fystack, Gaian’s finance team faced:

Frequent balance checks every few hours
Threshold‑based transfers that needed manual execution
Reliance on spreadsheets to track on‑chain funds and fiat reserves
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.
