July 2022 UPDATE: THIS TOOL (SMREPL) IS NOT UP-TO-DATE OR COMPATIBLE WITH OUR LATEST DEVNET. SMREPL DOESN'T CURRENTLY FUNCTION PROPERLY. WE WILL UPDATE WHEN WE CAN.

SMRepl - A Spacemesh REPL

Overview

SMRepl is a basic reference Spacemesh wallet and a full node manager command line REPL.

Smrepl is designed to work together with a locally running go-spacemesh full node or with the public Spacemesh API.

Target users are developers who want to hack on the Spacemesh platform and Spacemesh devnet or testnet users who are comfortable with terminal apps and REPLs.

For users who are not comfortable with terminal apps we recommend using Smapp - the Spacemesh App. Smapp is available for all major desktop platforms and includes a wallet and a full Spacemesh managed node.

TL;DR - Use with a Spacemesh Devnet or Testnet

1. Download a release of smrepl that the devnet supports to your computer or build it from source code
2. Download a release of go-spacemesh node that the devenet supports to your computer
3. Download a devnet or a testnet config file to your computer and save it in the same directory as your downloaded node
4. Start the node with the config file. e.g. ./go-spacemesh -c net_20_conf.json > node_logs.txt in a terminal window
5. Launch smrepl in another a terminal window. e.g. ./smrepl

Smrepl should connect to your node on startup.

Features

SMRepl is a Spacemesh API client and it implements basic wallet features via a REPL interface. Using it you can create a new coin account, execute transactions, check account balance and view transactions. You can also use it to se tup smeshing (Spacemesh mining) for your local node.

You can also use it when working on Spacemesh code by connecting it to a locally built node or to a local Spacemesh devnet

You can also connect to a public Spacemesh network API. In this configuration you can execute transactions, view account balances, past transactions and smeshing rewards.

Building

Build for your current platform with go:

go get && go build

Build for all platforms:

make

Build for a specific platforms:

make build-win

make build-mac

make build-linux

With docker:

make dockerbuild-go

CLI Flags

Use -wallet_directory to override the default of current working directory when opening and creating wallets.

Use -wallet to specify a wallet to pre-open when starting cli-wallet. cli-wallet will look in current directory unless -wallet_directory has been specified.

Using with a public Spacemesh API server

You can use your wallet without running a full node by connecting it to a public Spacemesh api service for a Spacemesh network. Use the -grpc-server and -secure flags connect to a remote Spacemesh api server. For example:

./cli_wallet_darwin_amd64 -server api-123.spacemesh.io:443 -secure

Note that communications with the server will be secure using https/tls but the wallet doesn't currently verify the server identity.

Your can find the grpc server url of a public Spacemesh testnet by copying the value of the grpcAPI field from the Spacemesh discovery srvice data.

Using with a local Spacemesh full node

1. Join a Spacemesh network by running go-spacemesh or Smapp on your computer.
2. Build the wallet from this repository and run it. For example on OS X:

make build-mac
./smrepl_darwin_amd64

By default, smrepl attempts to connect to the api server provided by your locally running Spacemesh full node using the default node's grpc api port (localhost:9092). When you run your full node directly in terminal, you can configure which api services will be available to your wallet by your node by changing entries int he api section of your node's config file:

{
   "api" : {
      "grpc": "node,mesh,globalstate,transaction,smesher"
   }
}
