Paymaster

In EntryPoint v0.7.0, significant updates have been introduced regarding paymaster interactions.

In v0.6, the PaymasterAndData field contained both the paymaster's address and any related data within a single field. In v0.7, this field has been split into two distinct fields:

paymaster: This represents the address of the paymaster.
paymasterData: This field now holds any additional data needed by the paymaster for operation validation.

This separation helps modularize the paymaster's responsibilities and makes it easier to handle specific paymaster-related logic, such as gas reimbursement or fee structure.

pm_getPaymasterStubData

This endpoint provides the stub values to be used in the paymaster-related fields of an unsigned user operation for gas estimation purposes.
