NEWS

New Centralized Exchange initiation - A CEX-grin.exchange idea is being announced by contributor k26dr. Grin Community glad to see new contributors.
Nonlogs privacy Cex . Another CEX CEX platform that’s yet to be launched. Grin pairs to be traded, already a testnet is available.
You can try for feedback and support for fixing bugs and UX!

Owners Forum message;

I’m hoping to receive support from the community. At NonLogs, i prioritize privacy, and I hope that one day we receive the support we deserve. If anyone could point me to documentation on how to run a node and services that can help set up Grin coin on the nonlogs backend, that would be very helpful. A testnet faucet link would also be appreciated.

Thanks!

For testing purposes only. You can get TEST coins from FORUM.
