Introduction
Polymesh is built with Substrate, which is a framework and a set of modules for creating a blockchain. Substrate provides tools that offer low-level access to everything that happens on a Substrate network and these tools work with Polymesh.
The Polymesh App is such a tool. Developers typically use it to explore the blockchain and transactions in depth.
Prerequisites
- A verified Polymesh Account.
- Enough POLYX balance on the account to cover transaction and protocol fees. Registering a new ticker currently has a 25 POLYX protocol fee. This fee is also charged when directly creating an asset without first registering a ticker in a separate transaction.
How to reserve a ticker with the Polymesh App
- Navigate to the Polymesh App.
- For the account at the top, select your account in your wallet.
-
For the extrinsic, select “asset”, then "registerUniqueTicker(ticker)", as per the below screenshot:

-
Ticker: Enter a ticker symbol with a 0x prefix in HEX format. It should look like this as per the following screenshot:

Note: Use a HEX converter like this one. For the Output delimiter string, select "None".
Example: Your ticker name is "TESTKN", which is "544553544B4E" in HEX. This HEX value should be padded with zeros to be 24 bytes like "544553544B4E00000000000" with a 0x prefix, so the value you should enter is "0x544553544B4E00000000000".
Shorter ticker names than 12 characters in HEX should be also padded with zeros up to 12 characters. - Once all data are filled, click on Submit transaction then confirm and sign the transaction with your wallet.
