FlexSub is a TypeScript SDK that enables developers to add flexible subscription payments to any Web3 application.

The Problem: Today's Web3 subscription experience is fragmented. Users have assets scattered across multiple chains, every payment incurs gas fees, and merchants want to receive stablecoins while users hold various tokens.

Reason to use Yellow Network: FlexSub integrates Yellow Network's state channels via @erc7824/nitrolite SDK to enable instant, gas-less micropayments. Users can open payment channels and stream micro-payments for pay-per-use subscription models.
