Use Halo on the web

The easiest way to use Halo: the web app. Sign in, top up with card or crypto, pick a model, and start prompting — with optional confidential (TEE) inference.

· Updated September 8, 2026 Getting startedConsumers

The web app at app.runhalo.xyz is the simplest way to use Halo — no CLI, no install. Sign in with a social account, an email address, a passkey, or a wallet; top up with a card or with crypto; and prompt any model on the network. There’s no provider account and no API key.

However you sign in, you land on the same account with the same balance — the one your agents spend from too. See one account for you and your agents.

Halo is in alpha on Base mainnet with real USDC.

What you need

Nothing but a browser. Sign in, add funds with a card, and you’re prompting.

You can also fund the account with crypto: send it from whatever chain it’s already sitting on, and it arrives as USDC on Base. No bridging, no swapping, and nothing to top up for gas.

Prompts never cost you a network fee — settlement gas is sponsored by the network’s facilitator, and there’s no wallet popup per message. If you do connect a wallet, the usual rule still applies: never share a seed phrase or private key with anyone, including support.

Step by step

  1. Open the app. Go to app.runhalo.xyz and sign in with a social account, an email address, a passkey, or a wallet.
  2. Add funds. Top up with a card, or send crypto from whatever chain it’s on — it arrives as USDC on Base in your Halo balance. You spend against that balance as you go, and unused funds stay yours.
  3. Pick a model. Browse the models operators are serving and choose one.
  4. Prompt. Send your message. The network routes it to an operator, you get the response, and you’re billed for the actual tokens used — not a flat per-request quote.

Keeping prompts private

Every request is end-to-end encrypted by default, so the relay that routes it only ever sees ciphertext.

For anything sensitive, use confidential mode, where available: the prompt is encrypted directly to a hardware enclave (a TEE) that even the serving operator can’t read, and the app verifies the hardware attestation on your device before trusting it. A verified confidential reply is marked as such in the app.

What it costs

You pay the operator’s price for the tokens you actually use, in USDC. Operators set their own prices, and the network settles the exact amount from your balance. Gas on every settlement is sponsored by Halo, so there are no separate network fees to worry about as you prompt.
