cast rpc

执行原始 JSON-RPC 请求

$ cast rpc --help

用法：cast rpc [OPTIONS] <METHOD> [PARAMS]...

参数：
  <METHOD>
          RPC method name

  [PARAMS]...
          RPC parameters
          
          Interpreted as JSON:
          
          cast rpc eth_getBlockByNumber 0x123 false => {"method":
          "eth_getBlockByNumber", "params": ["0x123", false] ... }

选项：
  -w, --raw
          Send raw JSON parameters
          
          The first param will be interpreted as a raw JSON array of params. If
          no params are given, stdin will be used. For example:
          
          cast rpc eth_getBlockByNumber '["0x123", false]' --raw => {"method":
          "eth_getBlockByNumber", "params": ["0x123", false] ... }

  -r, --rpc-url <URL>
          The RPC endpoint
          
          [env: ETH_RPC_URL=]

      --flashbots
          Use the Flashbots RPC URL with fast mode
          (<https://rpc.flashbots.net/fast>).
          
          This shares the transaction privately with all registered builders.
          
          See:
          <https://docs.flashbots.net/flashbots-protect/quick-start#faster-transactions>

      --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",
          "0x6bb38c26db65749ab6e472080a3d20a2f35776494e72016d1e339593f21c59bc"]'
          
          [env: ETH_RPC_JWT_SECRET=]
