I'm actually running a startup e-commerce website and accepting payments with BTC and ETH, i'm using on-premise bitcoind and geth with no issues at all for some months now.

I'm getting requests from users to accept more coins, mainly BNB, ENJ, XMR and bunch of 20 other coins ... 

I'm looking for technical solutions and staying on-premise (if possible), i don't seem to find a easy/straightforward solution till i crossed this app accepting 500+ coins and tokens  https://tip.cc/currencies 

Anything i'm missing over the space ?
