Rust Solana CLI program

This program is of Proof of Concept for creating a Solana Token (SPL Token), minting 10_000_000 of it, disable theminting and show the balance for this token with the command rust-solana-cli create-token --name=<token-name>.

The rust-solana-cli show-accounts command list all the tokens of the current account;

The rust-solana-cli connect command create a libp2p connection that can ping another libp2p connection if run in two separates terminals.

The program need you to have :

• the Solana Toolchain installed
• the spl-token cli installed
• a keypair generated (solana-keygen new)
• the RPC URL set to the solana testnet (http://api.testnet.solana.com)
• at least some SOL air dropped on your account.

Setting commands

$ solana-keygen new
$ solana config set --url https://api.testnet.solana.com

if needed :
$ solana config set --keypair ${HOME}/new-keypair.json

$ solana airdrop 1

Technologies used

• Rust
• libp2p
• Solana Token Program

Chat app

A basic chat application demonstrating libp2p and the mDNS and floodsub protocols.

Using two terminal windows, start two instances. If you local network allows mDNS, they will automatically connect. Type a message in either terminal and hit return: the message is sent and printed in the other terminal. Close with Ctrl-c.

You can of course open more terminal windows and add more participants. Dialing any of the other peers will propagate the new participant to all chat members and everyone will receive all messages.

If they don't automatically connect

If the nodes don't automatically connect, take note of the listening addresses of the first instance and start the second with one of the addresses as the first argument. In the first terminal window, run:

rust-solana-cli chat

It will print the PeerId and the listening addresses, e.g. Listening on "/ip4/0.0.0.0/tcp/24915"

In the second terminal window, start a new instance of the example with:

rust-solana-cli chat --address=/ip4/127.0.0.1/tcp/24915

The two nodes then connect.
