LTC not supported in DEX trading ? (segwit)

[ShorelineCrypto]

Komodo DeFi Framework (or atomicDEX-api) v2.0.0-beta is released and Komodo desktop/mobile wallet is under upgrade recently.

In recent new hardfork style upgrade on wallet and DEX, LTC now is wallet-only with no trading capability. All trading has to go through LTC-segwit

segwit is not supported in mmtools. This upgrade make mmtools not usable even with mm2 binary file workaround replacement.

smk762: using your repo for a fresh install, then overwrite with 2.0.0-beta mm2 binary to overwrite mmtool old version, then put back my config for LTC. It fails. I think the failure was that mmtools as wallet can not enable LTC-segwit, only the legacy LTC wallet is supported. Here are errors:

`

./enable ltc-segwit

One suggestion from smk for extra testing in discord:

k, probably best to await @webworker01 fix, I'm not so familiar with all the code, just took a guess for fixing. One other thing you can try is to edit your coins file to set wallet_only to false for LTC

Yes, need to wait @webworker01 fix on LTC pairs trading. Tried changinge "wallet_only" for LTC from true to false on coins/coin file, the mmtools can place buy an sell order on CHTA/LTC, but using Desktop new version to trade against that, not normal. In fact the debug print out in linux says that "LTC wallet only, best order removed". The trading is not working many times.

The errors by using smk's suggestion of making coins file under ~/mmtools/coins/coins from wallet_only true to false.
tested both on smk PR branch code, or the default master branch here. Both code failed with different errors. The smk's code error was reported above. Both ways in mmtools can place orders CHTA/LTC, both show up for desktop GUI to trade against. smk's branch code sell order was working, desktop was able to buy CHTA with LTC-segwith for 2 sats price. But buy order in mmtools failed, desktop GUI can not sell CHTA for 1 litecoin sats price.

The original master branch testing again, sell or buy order of CHTA/LTC pair is not tradable. In both cases, the Desktop GUI v7.0 wallet generated errors saying "Trade preimage timed out, try again".

In short, so far LTC is not really working, it can only serve as wallet only under new mm2 v2.0.0-beta upgrade.
