A guide for 0xcert public pre-sale

A guide for 0xcert public pre-sale

As the 0xcert Public Presale is approaching rapidly, here is a thorough guide to answer your questions if you get stuck in the process.

Important info about Public Presale

The only source for 0xcert Whitelisting, KYC, and Crowdsale is 0xcert’s official website https://0xcert.org and the only correct domain is 0xcert.org! To save any confusion, this is pronounced zero x cert and we use a zero (0) in the URL.

Public Presale starts on July 2, 17:00 CEST. It closes on July 4, 17:00.

Whitelist for Public Presale is open until July 2, 12:00 CEST.

Whitelist for Public Crowdsale is open from July 2, 12:01 CEST until July 18, 17:00 CEST.

Whitelisting for Public Presale counts as whitelisting for Public Crowdsale, too. No need to whitelist twice.

Starting off

If you want to partake in 0xcert Public Presale, first you need to apply to our Whitelist and pass the KYC procedure.

This is an obligatory measure to ensure the highest level of security to our supporters and contributors. Without it, you cannot participate in the 0xcert Presale and/or Crowdsale.

Step 1: KYC token and e-mail

At the beginning of the Presale, 0xcert will publish a contribution ETH address on the website.

If you have whitelisted and successfully passed the 0xcert KYC, a 0xcert KYC token will be issued and sent to the Ethereum wallet you provided in your Whitelist application (your ETH address). Only with this token you will be able to participate in 0xcert Public Presale and Public Crowdsale.

How to check whether you received the KYC token: click on the link below and in the 10th row insert your ETH address that you used during the KYC process. If you get a 1, then you have successfully received the token and you can participate in the Presale. If you get a 0, the token has not been sent yet.


Number 1 under balanceOf means, you have received the KYC token

Immediately after the launch of the Public Presale, on July 2, 17:00 CEST, you will receive an email reminding you of the start of the Presale.

The same email will also contain a security measure: the last 4 characters of the contribution address.

Please compare those 4 characters that you get in your email to the full-length ETH address on our website, and make sure they match the last 4 characters of the ETH address.

IMPORTANT! If the characters of the address from your email do not match the address on our website, DO NOT execute any transactions to it as you could permanently lose your funds!

These 4-characters will also be communicated through our official Telegram channel, Twitter, and Telegram group. Make sure you have at least 1 positive match to the numbers on the website.

Step 2: Send funds from your ETH wallet

IMPORTANT! Only using the KYC token you received, you can partake in the 0xcert Presale. Without the token, you can still go ahead and proceed with the transaction to the ETH address, but it will not be successful and your funds will not be transferred.

Login to your ETH wallet to send funds. You should use the same ETH wallet address as you used in your Whitelist and KYC applications. If you use a different wallet, it will not be recognized by the system and transaction will be declined.

IMPORTANT! Do NOT send your funds from an exchange as this could result in unsuccessful transaction and funds loss. You can only send funds from your ETH wallet that is ERC-20 compatible.

Once you have confirmed that the address on our website matches the last 4 characters you got in your email, you can use this address to send funds. Check the contribution address on our website, go to your ETH wallet, and insert it into the field "To Address" (or "Receiving Address").

Choose the amount of ETH you would like to contribute. NOTE: In the Presale, the minimum contribution is 1 ETH! There is no maximum limit.

Set the GAS/gwei for the transaction. Gas is enabling the transactions to be completed within the Ethereum network, so it should be high enough for the transaction to be executed successfully.

After double checking that the address is correct and the ETH amount is right, proceed to generating the transaction.

Step 3: Receiving ZXC tokens

Through the Presale smart contract, 0xcert will allocate ZXC tokens directly to contributors' Ethereum wallet account. The smart contract will lock up once all Presale ZXC tokens are sold.

You will receive the purchased tokens together with the 10% Presale bonus to your wallet within 24 hours after the confirmation of the ETH transaction.

Congratulations! You will soon become a proud owner of ZXC tokens!
