Secure your Assets with Unbreakable Blockchain Timestamping

No, we don't have access to your file. The hash is calculated directly in your browser, and no metadata is stored on our side.

No, you can pay by credit card or PayPal. We will handle the blockchain transaction ourselves.

You will receive a lifetime certificate containing all the necessary data to prove a timestamp. Technically, it's a file that contains your data and its hash, which is stored on the blockchain. Please note that a certificate only proves the time of the blockchain record, not the file's creation or modification time. Therefore, it proves that the file was created before that time. Certificate issuance takes approximately 24 hours.

Your information is absolutely private. Only a hash of your file is stored on the blockchain. You can prove a timestamp by presenting a certificate that contains all the necessary information.

We will send you a special link to check your blockchain transaction, which will also be included in the certificate you receive. Additionally, we will provide you with instructions on how to verify and prove your timestamp independently without using our service.

Yes, you can. You will receive a certificate with all the necessary information to prove your data via the blockchain.

Unfortunately, if you lose the original file or timestamp certificate, you will not be able to prove the timestamp. The same applies if you modify the content of the file, as it will change the hash. We recommend keeping the files safe and untouched along with the timestamp certificate that you receive.

We use the Ethereum (ETH) blockchain, which is one of the most popular and reliable blockchains on the market.

You can use any type of file. If you need to submit multiple files, you can compress them into a single archive. In addition, submitting a file is not mandatory—you can submit only text information if you prefer.
