Last updated 6 months ago

Background

As the current status of VRC25 standard, a few partner or users had been issued the token successfully. However, they are unable to regconize whether their transactions had been applied for ZeroGas or not. Hence this article is a guidance for how can they ensure that they applied the ZeroGas successfully.

Prerequisite

  • Assumed that the Token had been applied succesfully. If the token had not been created or not event apply it. Then kindly follow the guidance as here:

  • If the token had been issue via VicIssuer, then you can follow this guidance:

Getting Started

As the following image, the. user issued the token successfully. However, they know how to rectify whether the transaction is zero gas or not.

New Issued Token contract:

VicIssuer Apply Tx:

Step to verify with the example Tx:

In the example Tx we would notice a few following detail:

  • Tx Type: Gas Sponsored

  • Sender : 0xCc48C437020B17D881C719Ff53DF4e56022Fb61A

  • Receiver: 0xaa3984428fe62211c6485165c30584507175B3fb

  • Fee Payer (Token contract address): 0x4ff96908a19a2AF0E70404eF6Bc0925C0e43700A

As we can see, The Fee payer now is neither Sender or recepient. It is the token contract address, which means that the token had been registered for ZeroGas successfully.

For further testing, you can vist the VRCIssuer contract to figure whether the token is registered or not & the amout of sponsored fund is remaining by querying the token address.
