## Applying Vic ZeroGas Protocol

This step can be achieved by following step:

* Navigate to the **VRC25Issuer Contract** on **Vicscan**
  * Testnet: [https://testnet.vicscan.xyz/address/0x8c0faeb5C6bEd2129b8674F262Fd45c4e9468bee](https://testnet.vicscan.xyz/address/0x8c0faeb5C6bEd2129b8674F262Fd45c4e9468bee#code)
  * Mainnet:<https://www.vicscan.xyz/address/0x8c0faeb5c6bed2129b8674f262fd45c4e9468bee>
