The transaction will take place in multiple stages, including:

1. Swap: Exchanging ETH tokens for ZCN-ERC.
2. Increase Allowance: A higher allowance or gas limit typically signifies that the transaction will require more processing and prioritization.
3. Burn: Burning a specific amount of the currency with each trade.
4. Mint: Creating new units of the currency to replace those that were burned.

Please note that you will need to confirm transactions on Metamask at each stage. Refer to the screenshot on the upper right for reference.
