  -e, --etherscan-api-key <KEY>

          [env: ETHERSCAN_API_KEY=]

  -c, --chain <CHAIN>

          [env: CHAIN=]

  -r, --rpc-url <URL>

          [env: ETH_RPC_URL=]

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

      --jwt-secret <JWT_SECRET>
          JWT Secret for the RPC endpoint.
          
          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",

          [env: ETH_RPC_JWT_SECRET=]

      --rpc-timeout <RPC_TIMEOUT>
          Timeout for the RPC request in seconds.
          
          The specified timeout will be used to override the default timeout for
          RPC requests.
          
          Default value: 45
