can you by harmony browser are you referring to extension ? or the actual browser (aka chrome) ?

If browser, please update it.

If wallet, then you will need to export your private key or use frontier or guarda to import your account with the mnemonic if you still have.

</div>

do you have the a wallet that has your address one1ytxeedfu6xscs5tqht7h7q4jrnn6vwnz3jaf3n the wallet is used to sign the transaction, if no wallet, then you can’t sign. if no wallet, you will need to recreate your account using the mnemonic or private key which i hope you have a backup

I had a sleepless night and found out that node operators were not producing blocks waiting for sync but there was nothing to resemble an announcement here, which is a shame.I was really in panic not knowing what is happening not able to find any info anywhere. I am done with Harmony I cant live with such stressful moments. This chain is being raped by scammers, hackers and errors but the lack of informational infrastructure is crucial. The chain now looks ok to undelegate and get the hell out of here untill I still can. I feel like the harmony ship is sinking.

Hi I was referred by Mauricio to lodge my problem here.  
I am a delegator since 2020.  
I just found out over a million ONE transferred out from my wallet in an exploit not initiated by me.  
My Metamask activity log has been scrubbed and all txns are showing zero.

I am not a technical person, please tell me how to check if my wallet is being blacklisted above.  
My ONE address is one10jm8mz7wsd6y2etrgpy0xslf2r4sxcx2yhfu3k  
My EVM address is 0x7CB67D8bCE83744565634048f343e950eb0360Ca

Hey I am sorry to see that also happened to you. Unfortunately we cant do much here. I followed the fund and they went all the way to kucoin exchange hot wallet. It was the same pattern as other impacted victim.

And I was communicating the below :

> Victim(s) are advised to inform the local police or any other law enforcement institutions, and send us a duly signed official documents (with their agency’s letterhead), which states the brief introduction of the case, the information their agency requires, the legal ground of their agency to obtain the information, the identification of the contact person, and their commitment to confidentiality obligations, to our legal department: [rbenquiries@kucoin.com](mailto:rbenquiries@kucoin.com) and copy [risk\_management@kucoin.com](mailto:risk_management@kucoin.com).

Sorry for your loss …

I could not join the discord because of my antivirus program. The Nod32 detected an intrusion attempt when trying to verify. Given the so many scammers here I was honestly scared to ignore the warning message therefore decided not to continue pushing the discord connection. As a result I have decided to sell my coins and forget about Harmony for ever, I do not feel safe using the chain. There are more scammers here than normal people…this is just insane!

Hi Team, it’s been a week trying to delegate/transfer my Harmony one but still failed. It always says "Failed: Transaction was not mined within 50 blocks, please make sure transaction was properly sent. Be aware that it might still be mined!
