0gas SBT

Different Zytron networks have a contract that records whether users can be exempted from gas permissions. This permission is displayed in SBT form. Users can check whether there is SBT in their wallet to check whether 0gas interaction is possible.

On the testnet, developers can call the chaim() method to claim SBT for testing. Only one SBT can be claimed per address.

If users can't use 0gas, please send transaction to zytron network. Please refer to Set Priority Gas in Metamask to configure low gas.

Set Priority Gas in Metamask

Since zytron allows lower transaction gas support, metamask cannot be directly adapted in many cases. Therefore, you need to manually configure the Priority Gas Price.

To enable this function, please follow these step:

1. In the send transaction interface, click Estimated fee edit button (blue button).
2. Click Advanced.
3. You can adjust the Priority Gas Price according to your needs. The larger this value, the easier it is for the transaction to be confirmed by the network. We recommend using 0.002 as the Priority Gas Price.
4. To avoid doing this for every future transaction, please click "Save these values as my default for the..."
5. Click "Save" and comfirm transaction.
