Smart Contract Migration

Most of you know that ERC20 is just a piece of code stored in the Ethereum Blockchain. Interacting or querying with the logic within that smart contract code requires calling the functions or variables. Deploying smart contract in the Ethereum blockchain means cementing those functions and variables forever. It means that the code can’t be edited once deployed.

Recently we have encountered a minor problem, not a bug per se, but a potential error. Our current smart contract is working fine and even worked perfectly with the prototype registry smart contract we made and among decentralized exchanges we are currently listed on. However, that doesn’t mean something is working means it won’t encounter a problem in the future. The current token smart contract has a minor problem that might not work on another smart contract (e.g. other decentralized exchanges) or platforms (e.g. wallets or centralized exchanges).

This minor problem pops out when an exchange was examining our smart contract to see if the token would work perfectly on that exchange. They pointed out a minor potential problem in the code. We took an action immediately and made a new smart contract to mitigate potential errors in the future and to avoid expensive cost for redeployment. We are waiting for the exchange response if the new smart contract code is qualified on their platform before we begin the migration and redistribution to nearly 6000 token holders.

We would like to iterate that currently there is no problem with the code, we just took this measure of migrating to a new smart contract to mitigate the potential error that might pop out anytime on a different platform.

We are asking the community to withdraw their ZNT tokens from decentralized exchanges and we will conduct a token balance snapshot on between 12:00 UTC to 13:00 UTC of October 5, 2018. Don’t make the transfer of tokens during this time period to avoid losing your token. You don’t have to do anything other than leaving your token to your address and we will handle the migration.

Thank you for understanding.
