Looks like it is dead. There are 3 open PRs, older than 3 years:
https://github.com/nochowderforyou/clams/pullsand last commit is from 2017. Granted, one of the PR ("Update validation.cpp") probably results in a syntax error for the compiler, but the other 2 look fine and should be merged.
I passed this link to Xploited (the creator of clam and partner at FreeBitcoins.com).
Still the same open pull requests after a month. And looks like some big whale cashed out in November. So sorry to say this, but I guess now it is really dead. Liquidity for the only remaining exchange is 1 (the lowest possible is 0, goes up to 1000), which means you can't even trade it anymore:
https://coinmarketcap.com/currencies/clams/It appears to me that Poloniex has been dumping their CLAMS... sucks, but we will make it through it I strongly believe.
I've been slowly buying CLAMS for years now... still do, yolo.

And sorry about the "lot pricing" on the CLAM exchange, I hate that shit too, but it works. It's really complicated to make a trade between two people on an automated system, believe it or not.
