Also see another post, found here on SN, which shares an article on Bitcoin Magazine about this:

Bitmatrix Releases Mainnet Beta For Automated Market Maker On Liquid #73642 https://bitcoinmagazine.com/business/bitmatrix-releases-automated-market-maker-mainnet-beta-on-liquid

Perform trustless swaps via covenant-based liquidity pools on Bitcoin’s second layer.

oh snap! I used the alpha a few months ago. Worked great. Really close to the uniswap UX. Thrilled to see this go on mainnet!
