solXEN 420 miner v.1.1 Instructions

Views: 124

(thanks XenTzu)

This guide covers the installation of Rust and Solana, wallet creation and funding on the Solana testnet, and running the 420Miner script.

Prerequisites: Get access to a server where you can execute these commands. I am using Ubuntu 22.04 on WSL (Windows Subsystem for Linux) to illustrate the process in this guide.

Install Rust

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y

Install Solana

sh -c "$(curl -sSfL https://release.solana.com/stable/install)"

You may need to Configure Solana CLI (make sure your home directory matches):
export PATH="/home/ubuntu/.local/share/solana/install/active_release/bin:$PATH"

Confirm Solana is installed
solana --version

Create and Configure Wallets

Create a first wallet:

solana-keygen new

Configure Solana Testnet

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

Airdrop 1 Sol to your first wallet

solana airdrop 1

Check balance, should be 1 SOL
solana balance

Set up a second wallet

cp /home/ubuntu/.config/solana/id.json /home/ubuntu/.config/solana/id1.json

Create second wallet
solana-keygen new --force

Airdrop 1 Sol to your second wallet:
solana airdrop 1

If it doesn’t work and you encounter the following error:

, note that the Solana Testnet faucet limits the rate of SOL based on your computer’s wallet and IP address.

Easy fix:

Create a Cargo Project

cargo new my_project

If you get an error, install cargo first:

sudo apt install cargo

Navigate to the new directory:
cd my_project

Once done, edid Cargo.toml file to add solana-client and solana-sdk dependencies:
nano Cargo.toml

To do so, insert these lines into dependencies:

[dependencies]
solana-client = "1.10"
solana-sdk = "1.10"

Set Up & Run SolXEN Miner

Get SolXEN Miner (code) from the following URL:
https://gist.githubusercontent.com/jacklevin74/b3b3709aa3e66eab8f762c0fb4de53ff/raw/51ad482cd8c5a1d6c77457ae2c12378e4333a788/rs

Now, edit the miner script main.rs, remove all content from it and paste the content into it from the URL above:
nano src/main.rs

and

Please note, if your home directory is not /home/ubuntu, amend the script to ensure home directory paths are correct.
Once done, save the file.

Build the project

cargo build

Execute the compiled program (run the miner)
cargo run

Verify transactions on the testnet:

Check the updated SOL balance
solana balance

Check the transaction history and results by entering your wallet’s public address on the Solana explorer: https://explorer.solana.com/address/YOUR_WALLET_ADDRESS?cluster=testnet.

Navigate to Transaction History, to see the hashes with ‘420’ string to confirm the successful mining of SolXen:

Enjoy!
