Joining a public Telegram group carries no risk to your wallet or device by itself. The real risk in crypto groups is social engineering — unsolicited DMs from fake "admins" offering deals after you join. Shardeum Hanoi is listed in our directory, but the rule applies everywhere: never respond to DMs from unknown accounts after joining any crypto group. Your phone number is never visible to other members unless you've made it public in your Telegram privacy settings.

No. Telegram never notifies your contacts when you join or leave a group. Other members inside Shardeum Hanoi can see your username only if you post — your membership is not visible to anyone outside the group.

Shardeum Hanoi is a Telegram group for anyone interested in hanoi and events. Members can expect regular discussions on technology and cryptocurrency, along with blockchain to explore.

We verify every listing is publicly accessible, has a minimum member count, and exclude groups Telegram has marked as harmful. Shardeum Hanoi currently has 60 members and is marked as active.
