      --full
          [env: CAST_FULL_BLOCK=]

          Use the Flashbots RPC URL with fast mode (<https://rpc.flashbots.net/fast>).

          This shares the transaction privately with all registered builders.

          The JWT secret will be used to create a JWT for a RPC. For example, the following can be used to
          simulate a CL `engine_forkchoiceUpdated` call:

          cast rpc --jwt-secret <JWT_SECRET> engine_forkchoiceUpdatedV2
          '["0x6bb38c26db65749ab6e472080a3d20a2f35776494e72016d1e339593f21c59bc",
          "0x6bb38c26db65749ab6e472080a3d20a2f35776494e72016d1e339593f21c59bc",
          "0x6bb38c26db65749ab6e472080a3d20a2f35776494e72016d1e339593f21c59bc"]'
