StabL Gateway is a production-ready payment infrastructure that enables merchants to accept stablecoins from any blockchain while optimizing settlement costs through intelligent batching and instant liquidity provision.
Reason to use Yellow Network: Yellow Network integration provides the instant liquidity layer through off-chain state channels. The backend maintains a WebSocket connection to Yellow's clearnode, authenticates using EIP-712 signatures, and executes transfer RPC calls to credit merchants in their unified balance. This happens in under one second and costs zero gas since it's entirely off-chain. The current implementation uses a hybrid approach with real WebSocket connections and authentication flow, falling back to demo mode for the unfunded sandbox while maintaining production-ready architecture that requires only depositing funds to Yellow's custody contracts for full functionality.
