cannot estimateGas on ETH value sends #930
Description
Describe the bug
When sending eth value, we want users to estimateGas to get the encoded gasLimit to send their tx with. However, we currently do not allow calling estimateGas with no data:
optimism/l2geth/internal/ethapi/api.go
Lines 1024 to 1026 in 8d67991
To Reproduce
Try calling estimateGas with no calldata.
Expected behavior
We can call estimateGas when sending a transaction with ETH value
Additional Context
It's unclear whether this integration test will set the gasLimit to 21,000 by default or if it does call estimateGas
