Package rpc implements NEO-specific JSON-RPC 2.0 client and server. This package is currently in alpha and is subject to change.


After creating a client instance with or without a ClientConfig you can interact with the NEO blockchain by its exposed methods.

Some of the methods also allow to pass a verbose bool. This will return a more pretty printed response from the server instead of a raw hex string.

An example:

  endpoint := ""
  opts := rpc.ClientOptions{}

  client, err := rpc.NewClient(context.TODO(), endpoint, opts)
  if err != nil {

  if err := client.Ping(); err != nil {

  resp, err := client.GetAccountState("ATySFJAbLW7QHsZGHScLhxq6EyNBxx3eFP")
  if err != nil {


Merge structs so can be used by both server and client.
Add missing methods to client.
Allow client to connect using client cert.
More in-depth examples.

Supported methods


Unsupported methods



The server is written to support as much of the JSON-RPC 2.0 Spec as possible. The server is run as part of the node currently.


Implement HTTPS server.
Add remaining methods (Documented below).
Add Swagger spec and test using dredd in circleCI.

Example call

An example would be viewing the version of the node:

$ curl -X POST -d '{"jsonrpc": "2.0", "method": "getversion", "params": [], "id": 1}' http://localhost:20332

which would yield the response:

  "jsonrpc" : "2.0",
    "id" : 1,
    "result" : {
      "port" : 20333,
      "useragent" : "/NEO-GO:0.36.0-dev/",
      "nonce" : 9318417
