Create a Keychain

Overview​

To become a Keychain operator, you need to create and configure a Keychain entity onchain, as shown in this guide. To interact with the chain, you'll use node commands.

You can either run a local chain to test your configuration or interact with Chiado testnet. In the provided code snippets, you'll find tabs with different versions of node commands.

tip

You can skip this guide and test a preconfigured Keychain. Just run a local node using our just script and start fulfilling requests.

Prerequisites​

Before you start, complete the following prerequisites:

  • Set up a Warden account on a local chain or a testnet. Note down your key name.

  • If you're deploying on a local chain, make sure it's running. You can start your chain by running wardend start in a separate terminal window.

1. Register a Keychain​

The following steps show how to register a new Keychain entity onchain.

  1. Run this command to create a new Keychain:

    wardend tx warden new-keychain \
      --from shulgin \
      --name 'my-keychain-name' \
      --chain-id warden_1337-1

    Specify the required details:

    • name: The Keychain name
    • from: Your local account name (key name)
    • chain-id: The ID of the chain you're running

    Optionally, you can also set the following:

    • description: The Keychain description
    • keychain-fees: Keychain fees in aWARD (0.000000000000000001 WARD)
      • key_req: A fee for creating a key pair
      • sig_req: A fee for signing a transaction
    • For more settings, see wardend tx warden new-keychain --help.

  2. Confirm the transaction. A new Keychain object will be created onchain.

  3. Every Keychain is created with a Keychain ID that identifies it in key and signature requests and collects fees from users. You'll need this ID to operate your Keychain. Run the following command and check the id field in the output:

    wardend query warden keychains
    keychains:
    - admins:
      - warden1h7akmejqcrafp3mfpjqamghh89kzmkgjzsy3mc
      creator: warden1h7akmejqcrafp3mfpjqamghh89kzmkgjzsy3mc
      description: my-keychain-description
      fees:
        key_req:
       - amount: "100"
         denom: award
     sig_req:
       - amount: "1"
         denom: award
      id: "1"
      name: my-keychain-name
    pagination:
      total: "1"

2. Add a Keychain Writer​

A Keychain Writer is an account that can write Keychain results (public keys and signatures) to the chain. The Keychain Writers list is essentially an allowlist of accounts that can interact on behalf of the Keychain.

To add a Keychain Writer, take these steps:

  1. Create a new key (account) with a preferred name:

    wardend keys add my-keychain-writer-name

  2. Write down the mnemonic phrase and the address of the new account. You'll need this information to interact with the chain and restore the account. Note that only this address will be able to publish signatures and public keys on behalf of the Keychain.

    warning

    The seed phrase is the only way to restore your keys. Losing it can result in the irrecoverable loss of WARD tokens.

    tip

    You can always check your public address by running this command:

    wardend keys show my-keychain-writer-name --address

  3. Now you need to fund the account. If you're running a local chain, execute the command below. After send, specify your key name. Also set the Keychain Writer name and the chain ID.

    wardend tx bank send \
      shulgin \
      $(wardend keys show --address my-keychain-writer-name) \
      1000000000000000000award \
      --chain-id warden_1337-1

    If you're interacting with Chiado, fund your key using Chiado faucet and the public address returned in the previous step.

  4. Check the Keychain Writer balance:

    wardend query bank balances my-keychain-writer-name
    tip

    In this example, we used $(wardend keys show --address my-keychain-writer-name) to get the Keychain Writer address by its name. Alternatively, you can just specify the address obtained earlier.

  5. Finally, add the Writer account to your Keychain. In the --from flag, specify your key name. Also set the Keychain ID from Step 1.3, your Keychain writer name, and the chain ID:

    wardend tx warden add-keychain-writer \
      --from shulgin \
      --keychain-id 1 \
      --writer $(wardend keys show --address my-keychain-writer-name) \
      --chain-id warden_1337-1

  6. To check the result, get the list of Keychains:

    wardend query warden keychains

    In the output, find your Keychain and check the writers list:

    keychains:
    - admins:
      - warden1h7akmejqcrafp3mfpjqamghh89kzmkgjzsy3mc
      creator: warden1h7akmejqcrafp3mfpjqamghh89kzmkgjzsy3mc
      description: my-keychain-description
      fees:
        key_req:
       - amount: "100"
         denom: award
     sig_req:
       - amount: "1"
         denom: award
      id: "1"
      name: my-keychain-name
      writers:
        - warden18my6wqsrf5ek85znp8x202wwyg8rw4fqhy54k2
    pagination:
      total: "1"
