Welcome to Onside Flow

An introduction to Onside Flow, the plug-and-play web widget that enables you to accept multi-chain crypto deposits and swaps in your application.

The Onside Flow allows users to deposit crypto assets from any supported token and chain and receive the equivalent value in a target token (e.g., SOL or USDC) directly into your wallet, exchange or dApp. Once integrated, it allows your users to swap 14 most popular tokens across 11 blockchains. The flow includes deposit address generation, token swap, and payout.
