Subkey create KEYS for Kusama / Polkadot / Substrate

Kusama is a canary network for developers to run experiments in a Polkadot-like environment. Think of Kusama as an early proving ground for things like upgradeable runtimes, on-chain governance, and parachains.

Have fun on Kusama! Explore the politics, hone your validator setup, campaign for the council, or vie for a parachain spot. And most of all… expect chaos.

Kusama is owned by the folks who hold Kusama tokens (KSM). There’s no central kill switch. The community rules the network through on-chain governance.

Security caveat: Kusama is experimental! There are no guarantees.

For play with Kusama tokens AkA KSM need one account and [subkey] is the more secure way.

Subkey is a key-generation utility that is developed alongside Substrate. Its main features are generating sr25519 and ed25519 key pairs, encoding SS58 addresses, and restoring keys from mnemonics and raw seeds. It can also create and verify signatures, including for encoded transactions.

Soft for this installation was Ubuntu 18.04

sudo apt install make clang pkg-config libssl-dev
curl https://sh.rustup.rs -sSf | sh
rustup update nightly
rustup target add wasm32-unknown-unknown --toolchain nightly
rustup update stable
cargo install --git https://github.com/alexcrichton/wasm-gc

Install subkey one-line command:

cargo install --force --git https://github.com/paritytech/substrate subkey

After the installation you can disconnect the internet connection in the computer and use subkey on the same machine that is not connected to the internet for added security.

Generate an sr25519 key

subkey --network kusama generate

Results the account and recovery info.

For even more security, use --words 24 (supports 12, 15, 18, 21, and 24):

subkey --network kusama generate --words 24

The output gives us the following information about our key:

• Secret phrase (aka “Mnemonic Phrase”) — A series of English words that encodes the seed in a more human-friendly way. Mnemonic phrases were first introduced in Bitcoin (see BIP39) and make it much easier to write down your key by hand.
• Secret Seed (aka “Private Key” or “Raw Seed”) — The minimum necessary information to restore the key pair. All other information is calculated from the seed.
• Public Key (hex) — The public half of the cryptographic key pair in hexadecimal.
• Address (SS58) (aka “Public Address”) — An SS58-encoded address based on the public key.

The Address (SS58) field is what you should use to claim your KSM tokens. Never share your Secret phrase or Secret seed, as these can both control your funds.

NOTE: Previous versions of subkey only generated Substrate addresses. If you do not want to generate a new seed, you can convert the Substrate address to a Kusama address by following this section.
