I have never seen mention of an official Telegram channel in the official docs.
Warning: Telegram and Discord are a haven for people trying to scam you. Never give anybody your seed phrase or private key. Even support officials and admins will never ask for your seed phrase or private key. And never use a wallet app that you have not used before if somebody asks you to. They will fake a real wallet and use the fake wallet to steal all of your tokens.
@emily Unfortunately, once a transaction is sent it is permanent in less than a second and there is no way to undo. If the address is invalid the tokens are lost forever.
Solana has no way to know when you provide an address that doesn’t exist, because that address could have been created offline by some user who has just never connected to Solana before.
I’m so sorry that you lost your tokens!
