Instant exchange of native BTC with native USDT with near-zero fee.
This can be done using Lightning Network (for BTC) and Connext network (for ETH, BSC, Matic and more).
This is a game-changer, instant and zero-fee, no infinite wait for the Bitcoin blockchain and high gas fee on Ethereum.
The DEX will work with an order book as you see in the video and as well with a simple swap UI, easier to use for casual traders.
Instant TXs and settlements.
