How It Works

KaleidoSwap — RGB assets on Lightning Network KaleidoSwap combines three technologies to enable fast, private, and scalable asset trading:
Client-validated smart contracts on Bitcoin. Assets are issued and transferred off-chain with Bitcoin’s security guarantees — no blockchain bloat, full privacy.
Second-layer payment channels for instant, low-cost transactions. Swaps settle in milliseconds with fees measured in satoshis.
LSPs provide channel liquidity and routing. Connect to an LSP and start trading without managing infrastructure.
