BYOB - Bring Your Own Blockchain

If you want to have full control over your blockchain deployment, e.g., if you want to reset the state repeatedly or need more funds than a faucet can provide for a single account, you will need to run your own blockchain. For this purpose, we provide a Docker image which runs in standalone mode. This means that the blockchain doesn't act as a parachain but as an independent chain. There is no need to run a Relay Chain and register the KILT chain as a parachain. This greatly simplifies the setup.

You only need to start the Docker image:

docker run --rm -it -p 9944:9944 -p 9933:9933 kiltprotocol/mashnet-node:latest --dev --ws-external --rpc-external

You should see output similar to the following:

Congratulations! You are running your own KILT blockchain. šŸŽ‰

The blockchain exposes a WebSocket endpoint on port 9944 and an RPC endpoint on port 9933. You can test that by calling an RPC endpoint using curl.

curl -H "Content-Type: application/json" -d '{"id":1, "jsonrpc":"2.0", "method": "system_name", "params":[]}' http://127.0.0.1:9933/

This should give you {"jsonrpc":"2.0","result":"KILT Node","id":1} as a response.

In addition, you can also connect to the exposed WebSocket endpoints using your script. Simply replace the WebSocket address with ws://127.0.0.1:9944. Please note that we connect to the port 9944 as we are using the WebSocket protocol for our SDK and not bare HTTP.

The --dev parameter provides a pre-funded account which you can use as a faucet, and that has the following mnemonic: receive clutch item involve chaos clutch furnace arrest claw isolate okay together.

You can create the account with the following SDK function:

// Creates an ed25519 key by default which is required to access the funds.
const devFaucet = Crypto.makeKeypairFromUri(faucetSeed)

With the new devFaucet, you can transfer funds to other accounts and test all the KILT features that require tx fee payment.
