You can use this simple tool to quicky activate your XTZ without having to bring your private data out of cold storage.
THIS IS ONLY FOR FUNDRAISER WALLETS WHO HAVE COMPLETED KYC
If you would like to activate your allocation, than this is a safe method. We do not need to know your private key to do so, we just use your public wallet address (or pkh/public key hash). This address starts with "tz1" and can be used within explorers to view your balance.
The only way a user can obtain your XTZ is if they have access to your secret key, as well as the activation code. This tool won't leak your secret key (because you should never enter it here).
You need to wait for the activation operation to be included in a block, this could take a few minutes (usually) but may be longer if the network slows down.
