Getting a Sequencer Signature

Blocks must be cosigned by the Sequencer. The Sequencer blindly signs any number of candidate blocks for the current Builder via a simple API.

The Sequencer API accepts a SignRequest via a POST call to the /signBlock endpoint, and returns a SignResponse. For details on calculating the contents hash, see the rust builder example.

API Endpoint
