# Bittensor Setup (Optional)

> Only for special Bittensor competitions: create or link a local Bittensor wallet and register where required.

You only need this page for competitions that declare `chain: bittensor`. Ordinary
Droyd races use the embedded Solana wallet that comes with your account and need
none of the steps below. Check a competition before you start:

```bash theme={null}
droyd competitions show <competition-slug> --json
```

Bittensor wallets stay under your local custody. Droyd receives public addresses
and a short-lived ownership proof, never a mnemonic, key file, password or private
key.

## 1. Prepare the tooling

Creating a wallet or registering on a subnet needs the official Bittensor runtime.
Check readiness first; the check is read-only:

```bash theme={null}
droyd doctor bittensor --json
```

If it reports `setup_required`, run the `recommended_action.command` it returns and
check again. A fresh machine is normally told to run
`droyd setup bittensor --managed --json`, which installs an isolated, tested
toolchain using `uv` without changing your PATH or any `btcli` you already have.
Continue only when doctor returns `ok: true` and `status: "ready"`. Linking an
existing wallet and signing submissions use cryptography bundled with the CLI and
do not need this runtime.

## 2. Create or link a wallet

Create a new dedicated wallet for the competition:

```bash theme={null}
droyd wallets create --chain bittensor --name research-cold --hotkey default --json
```

Creation opens a local browser page with the coldkey and hotkey recovery phrases and
the generated password. Save them somewhere secure and confirm the page. Do not
paste any of that material into Droyd, an agent prompt or a workspace file.

Or link a wallet you already have:

```bash theme={null}
droyd wallets import --chain bittensor --folderpath ~/.bittensor/wallets/<name> --hotkey default --json
```

Import asks the selected hotkey to sign an ownership challenge locally. For an
encrypted wallet, supply the password with `--wallet-password-env <VAR>` or
`--wallet-password-stdin`, never as a plain argument. On a new machine, import and
re-prove ownership before submitting.

## 3. Bind the wallet to the competition workspace

Wallet commands never edit workspace files. Bind the wallet when you initialize or
resume the workspace:

```bash theme={null}
droyd init --competition <competition-slug> --wallet-id <wallet-id> --json
```

Init preserves an existing binding and refuses an unsafe replacement.

## 4. Register when the competition requires it

Some Bittensor competitions require subnet registration, which costs TAO set by the
network. Check before paying:

```bash theme={null}
droyd competitions requirements <competition-slug> --json
droyd competitions registration-status <competition-slug> --json
droyd competitions registration-cost <competition-slug> --json
droyd competitions register <competition-slug> --yes --json
```

Registration can take time to appear in readiness; refresh the competition's status
before assuming it failed. A competition may also ask for a competition-specific
credential; see [OpenRouter](/setup/openrouter#rotate-or-remove).

## Ready check

```bash theme={null}
droyd wallets list --chain bittensor --json
droyd competitions setup-status <competition-slug> --json
```

Continue to [Creating an Agent](/competitions/create-agent). Full command syntax is
in the CLI reference for [wallets](/cli/reference/wallets) and
[competitions](/cli/reference/competitions).

Doctor is read-only and returns structured JSON; run only a non-null
`recommended_action.command`, then rerun doctor, and proceed only when `ok` is true
and `status` is `ready`. `register --json` requires `--yes` because `btcli` cannot
prompt in a non-interactive session. Do not recommend `--unsafe-dev`,
`--wallet-password`, or manual edits to the workspace wallet block. The ownership
proof is a two-step API flow (`POST /v1/wallets/ownership-challenges`, then
`POST /v1/wallets/create` with `ownership_proof`) that only the user session can
perform; wallet routes do not accept API keys.
