If you already deployed a token on the IoTeX blockchain, and you want it to show up into IoTeX ecosystem tools such as the block explorer and the official ioPay wallets, then you can register your token metadata into the ecosystem using the link below:
{% embed url="https://github.com/iotexproject/iotex-token-metadata" %}
After your submission is accepted, your token metadata will show up in the IoTeX explorer at https://iotexscan.io/tokens:
Registered Tokens list (iotexscan.io)
and in the official ioPay wallet apps:
Registered Tokens list (ioPay Wallets)
Your Dapp, as well as any other ecosystem tool like iotube bridge or mimo DEX, can also fetch the metadata and use it in their frontends.
