yes i am. i have also implemented Monero<->Litecoin(MWEB) atomic swaps so there will be a nice way to acquire Grin and Monero by getting LTC from a regulated CEX and then swapping over Janus. since MWEB is also fungible, this provides a practical way to acquire Grin and Monero without paying a premium, since there is no “dirty coins”, which made most atomic swaps impractical.
i still have a lot to figure out, and i want to get this right, so i will need more time before an alpha release.
