Yes. We have proposed to them collaboration. We did implement a synthetic stablecoin "channel" using known hosted channels tech from Bitcoin Lightning Wallet and Simple Bitcoin Wallet in our SBW fork Valet. But Kollider rejected it, and later, they released their browser wallet.

Valet still works, by the way, and anybody could use it for regular channels. Standard Sats will maintain it as long as we can.

Kollider was working with the central limit order book while LNMarkets was basically a broker, and they arbitrage quite harsh KYC rules of Bitfinex.

Kollider tech could become a base of future satoshi-denominated financial products. However, likely it will be somebody else.
