Key Generation using Subkey Tool

Subkey is a command-line utility used with Substrate-based chains for managing keys. Here's how you can generate keys for GGX chain using Subkey:

You may need to install some dependencies first. You can install them by running:

sudo apt install -y build-essential protobuf-compiler pkg-config libssl-dev clang libclang-dev

If you do not have Rust installed, you can install it with:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env

rustup install nightly
rustup target add wasm32-unknown-unknown --toolchain nightly

git clone https://github.com/paritytech/substrate.git
cd substrate/bin/utils/subkey
cargo +nightly run

You can now generate a key with:

For ed25519:

cargo +nightly run -- generate -w 24 --output-type json --scheme ed25519 >$HOME/keys/ed25519key.json

for sr25519:

cargo +nightly run -- generate -w 24 --output-type json --scheme sr25519 >$HOME/keys/sr25519key.json
