Arbitrum is a technology suite designed to scale Ethereum. You can use Arbitrum chains to do all things you do on Ethereum — use Web3 apps, deploy smart contracts, etc., but your transactions will be cheaper and faster.
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. Arbitrum AirDrop 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 Arbitrum AirDrop can see your username only if you post — your membership is not visible to anyone outside the group.
Arbitrum AirDrop is a Telegram group in the Ethereum Usa Telegram Groups category.
We verify every listing is publicly accessible, has a minimum member count, and exclude groups Telegram has marked as harmful. If you've joined Arbitrum AirDrop and noticed something suspicious — a review on this page helps others stay safe.
