Ask anything.Leave no name.
Claude, GPT and Gemini, paid from a private balance on Robinhood Chain. No account, no email, no card, and nothing that ties a wallet to what you ask.
Beta, unaudited. Pool deposits are capped while that is true.
Draft a firm, polite message telling my landlord the heater has been broken for a week.
Here is a short version you can send as is: “Hi Dana, the heater in unit 4 has not worked since last Tuesday. Could someone fix it by Friday? Thanks, Sam.”
Who sees what
Privacy claims are only as good as their edges, so here are the edges. Read across a row to see who learns that fact.
| Fact | Sigilo's server | The model provider | Anyone watching the chain | Your browser |
|---|---|---|---|---|
| What you type | Passes it to the model. Keeps no copy. | Reads it to answer, on a zero-retention endpoint. Not told who you are. | Never | Keeps it, encrypted with your phrase |
| Which wallet paid | Never | Never | Sees your deposit into the pool, not what it bought | Knows |
| How much you spend | A balance under a random pass, no name | Only Sigilo's total usage | Never: credit payments are private transfers | Knows |
| Your IP address | Sees it while answering. Not logged. | Never: requests come from Sigilo | Never | — |
- Deposits are public. Moving ETH into your private balance shows your wallet and the amount on-chain. Waiting, and not buying credit for exactly what you deposited, weakens that link.
- Some of this is a promise, some is math. Payment privacy comes from zero-knowledge proofs made on your device, which no server can undo. "Keeps no copy" and "not logged" describe the code we run. Use a VPN or Tor if you would rather not trust that.
- A new pool is a small crowd. Privacy grows with the number of people using the pool.
How paying works
-
Add ETH
Deposit from any wallet into your private balance on Robinhood Chain. This is the one public step.
-
Buy credit
Your browser makes a zero-knowledge proof and pays Sigilo inside the pool. On-chain it looks like any other pool transfer. A relay pays the gas, so no wallet of yours appears.
-
Ask
Each reply costs what the model provider charges plus 15%, shown under the reply. No subscription. Credit never expires.
Your 24-word recovery phrase restores all of it on any device: the private balance, the credit and the key to your saved conversations.
What it costs
The provider's price per token, plus 15% for running Sigilo. A short question and answer usually costs a fraction of a cent.
Credit comes in $5, $10, $25 and $50, or any amount from $1 to $200.

$SIGILO
Launching on PONS V2, Robinhood Chain.
- What holding does
- Each month, holders at a snapshot block share an AI allowance. Your share is your holding over the circulating supply, up to a per-wallet cap. Claim it in the app.
- Where fees go
- Half of the token's PONS creator fees fund the monthly allowance; half pay for model credit, relay gas and servers. Each month's budget, snapshot and claims are published.
- What it does not do
- You never need SIGILO to use Sigilo. Claiming signs with your wallet, so that allowance is linked to it; your private credit stays separate. There is no promise of price or returns.
Questions
Is my MetaMask or Robinhood wallet my Sigilo wallet?
No. Sigilo makes a separate 24-word phrase for your private balance and credit. Your usual wallet only funds deposits and, if you hold $SIGILO, claims the allowance.
What happens to my money if Sigilo goes away?
Your private ETH is in an ownerless contract. With your phrase and any public node you can withdraw it without us. Unspent credit is a balance on Sigilo's service, so keep it modest.
Which models can I use?
Current models from Anthropic, OpenAI, Google and others, through OpenRouter, restricted to endpoints that keep no data. If a model has no such endpoint at the moment, Sigilo hides it rather than fall back.
Can Sigilo read my conversations?
They pass through Sigilo's server on the way to the model and are not stored there. Your saved history lives only in your browser, encrypted with a key from your phrase.
Has this been audited?
Not yet. The pool is the same contract code as Veilport's live pool, with a public trusted setup and extensive tests, but no independent audit. Deposits are capped while that is true.
Can I turn credit back into ETH?
No. Credit pays for AI only. Buy what you expect to use.
