eth_sendUserOperation

Please refer to 1Balance & Relay to create a sponsorApiKey.

In case of sponsoring gas with 1Balance the maxFeePerGas and paymasterAndData fields must be zero to avoid on-chain EntryPoint fee payments. This decreases overhead and leads to gas savings.

Consider using the staging bundler RPC URL for use cases other than sponsoring with 1Balance.
