sponsorUserOperation
The Pimlico paymaster actions in permissionless.js only work with the v2 Pimlico API. The v1 API for paymasters is deprecated and will be removed in the future.
This version, instead of simply signing over the passed-in User Operation, estimates the gas values for the User Operation and then signs over the estimated gas values, returning not only the paymasterAndData but also the preVerificationGas, verificationGasLimit, and callGasLimit.
Estimates the gas values for the User Operation and sponsors the operation with the new gas values.
