Lightning Bridge provides instant cross-chain connection of Bitcoin Lightning, Ethereum, Polygon, BNB Chain, and Solana, with a special focus on stablecoins (USDC, USDT, and BUSD). CashApp users can send Bitcoin Lightning from their account to receive tokens in a flash. We also accept Credit/Debit via our Stripe integration.

We aim to expand this list with Bitcoin (on-chain) and other popular EVM compatible chains such as Arbitrum and Optimism soon.
