[General] EIP 1559

Environment

Testnet

Provide a brief description of the functionality you're trying to implement and the issue you are running into.

In this document, it means that
In ZKsync Era, while the EIP-1559 transaction format is supported, the maxFeePerGas and maxPriorityFeePerGas parameters are not utilized.
Can you explain more about this? Does it literally mean that only the base fee is supported? If so, any plans to start using them?
If a tx is sent with only legacy gas price value, will zksync treat it as a base fee value?

In the zkSync Era, while the EIP-1559 transaction format is indeed supported, the specific parameters maxFeePerGas and maxPriorityFeePerGas are not utilized. This means that even though transactions can be formatted according to EIP-1559, the dynamic fee components that typically allow users to specify a maximum fee and a priority fee are not active in this environment.

Here's a breakdown of how this works in zkSync Era:

• Base Fee: This is the only part of the EIP-1559 fee model that is effectively used. It represents the minimum fee that must be paid for transactions to be included in a block.
• maxFeePerGas and maxPriorityFeePerGas: These parameters, although present in the transaction format, do not influence transaction processing in zkSync Era.

Regarding your question about sending a transaction with only a legacy gas price value, in zkSync Era, such a transaction would not treat the legacy gas price as a base fee. Instead, the transaction would likely be processed using the standard fee mechanisms that do not utilize the EIP-1559 model.

As for future plans to start using maxFeePerGas and maxPriorityFeePerGas, there is no specific information provided in the documentation about when or if these parameters will be fully implemented. It's possible that the current model could change as the network evolves and adapts to user needs and technological advancements.

For the most accurate and up-to-date information, you might want to follow official zkSync communications or reach out directly to the development team for insights into upcoming features and changes in the fee structure.
