There are a few eth_ calls that are also relayed as part of the sidecar.

| This design achieves the two main roles of the sidecar: | ||
|
|
||
| 1. Obfuscation: The presence of the external builder is hidden from both op-node and op-geth. From their perspective, they are communicating with each other as usual. | ||
|
|
||
| 2. External Communication Management: The sidecar handles all communication with the external builder, including authentication and payload selection. | ||
