GStable provides enterprise-grade stablecoin payment infrastructure, designed to bring merchants a collection solution that combines SaaS-level integration experience with Web3 settlement efficiency.
Merchants can quickly integrate via No-code Payment Link or API Integration Checkout, utilizing underlying full-chain interoperability and non-custodial settlement technology to achieve global, low-cost, zero-fund-risk instant collection.
Core Features
1. Full-Chain Payment & Auto Routing
Supports stablecoin payments across any chain. Users can pay using any mainstream asset (e.g., USDC on Arbitrum), and the system automatically completes cross-chain and settlement through smart routing. Merchants only need to specify the receiving asset on the target chain (e.g., USDT on Polygon) without worrying about intermediate links.
2. Non-Custodial & Instant Settlement
Adopts a non-custodial architecture without a capital pool. Funds go peer-to-peer from the user's wallet directly to the merchant's self-custodial wallet, eliminating platform redemption risks. Thanks to high-performance on-chain routing, the entire settlement process is typically completed within 30 to 40 seconds.
3. Payment & Settlement Asset Decoupling
Automatically smooths out asset differences between buyers and sellers. Merchants only need to set the final settlement asset, and users can freely choose their held assets to pay. The system automatically handles exchange rates and conversions, simplifying financial reconciliation.
4. Simple, Transparent & Extremely Low Fee Structure
Implements a Fixed Rate system based on payment paths. Depending on the combination of payment currency and settlement currency, the rate is fixed between 0.2% - 0.6%. The fee structure is stable long-term with no hidden fees, ensuring predictable costs.
