alchemy_requestPaymasterAndData

Please use alchemy_requestGasAndPaymasterAndData instead.

While you can use alchemy_requestPaymasterAndData to request a paymaster signature, it's important to note that this function requires gas fields to be part of the UserOperation passed as a parameter. These gas fields are influenced by the response of this endpoint, creating a circular dependency.

To simplify this process, we introduced alchemy_requestGasAndPaymasterAndData. This function both estimates gas and provides signed paymaster and paymasterData fields, therefore resolving the circular dependency.
