Get ready before $PROVN launches.
One address, posted in two places.
Provn will post the official $PROVN contract address on this page and on X at x.com/provn. Those two are the only sources. Copy the address from one and check it against the other before you paste it anywhere.
Provn $PROVN
Robinhood Chain · 4663
Contract address
Not deployed. The address will appear here at launch.
Don't search for the token by name. Anyone can deploy a token called Provn with the ticker PROVN, and some people will. An address you found through search is the easiest way to end up holding the wrong token.
Four mistakes that cost people money.
An address from anywhere else is fake.
Until Provn posts the contract here and on X, any $PROVN address you see belongs to someone else. After launch, the real one is the address that appears in both places.
There is no presale and no whitelist.
Provn has run no presale, whitelist or early-access round, and won't run one. Anyone offering you a spot wants your ETH.
Add the network yourself.
A site that adds Robinhood Chain to your wallet for you can point it at a fake RPC that shows fake balances. Enter the values from the table below by hand, then connect.
Keep ETH for gas.
Robinhood Chain charges fees in ETH. Bridge more than you plan to spend, because a wallet with no ETH left can't move or sell anything.
Three steps, once Provn posts the contract.
- 01
Bridge ETH to Robinhood Chain
Send a small test amount first, then the rest.
From Ethereum or another EVM chain
Open Relay or Across, connect your wallet, pick Robinhood Chain as the destination and send ETH.
From an exchange
Check whether the exchange can withdraw to Robinhood Chain. If it can't, withdraw to your own wallet and bridge from there.
- 02
Confirm it arrived
Switch your wallet to Robinhood Chain and look for the ETH. If the wallet shows nothing, paste your address into the block explorer, and trust the explorer over the wallet screen.
- 03
Buy on the launch venue
Open the launch venue announced on X. Paste the contract address from this page into its search field instead of typing the name, and check that the token page shows Provn and $PROVN before you swap. Leave some ETH for fees.
Add Robinhood Chain by hand.
Most bridges can add the network for you. If you'd rather do it yourself, use these values and compare each one before you save.

Questions about the product
What is a receipt?
A small JSON record the gateway signs for each metered call. It lists the model, the engine that served it, token or CPU units, the cost, the key id and a fingerprint of your request. Your prompt and the output are not in it.
Does Provn see my prompts?
The gateway holds your prompt in memory while it serves the call and writes none of it to storage or logs. It keeps metadata: model, units, cost, timestamps, key id, fingerprint and status. The upstream model host does process the prompt in plaintext, since that host runs the model.
What does the signature prove?
A valid signature shows that the holder of the published signer key issued that exact payload and that nobody edited it afterwards. You can check it offline against the address from GET /v1/signer, or paste it into /verify.
And what doesn't it prove?
It doesn't show that the answer is right. Provn can't attest what the upstream host ran on its own hardware either. A receipt records what the gateway metered, where it routed the call and what it charged.
What happens when a key hits its cap?
The gateway returns HTTP 402 with cap_reached and makes no upstream call, so the key spends nothing more. Raise the cap in the dashboard, or wait for a daily or monthly window to roll over.
How does anchoring work, and when is it off?
Provn hashes receipts into a Merkle tree and writes the root into a 0-value transaction on Robinhood Chain. That requires a funded signer in PROVN_ANCHOR_KEY. Without one, Provn still seals each batch and labels it unanchored, and GET /v1/receipts/:id/proof tells you which case your receipt is in.
How do I top up?
From the wallet you signed in with, send ETH on Robinhood Chain to the treasury address shown in the dashboard, then paste the transaction hash. The gateway checks the transaction on chain and credits USD at the ETH/USD rate at that moment. Deployments that haven't set a treasury address have top-ups turned off.
What does the free public upstream mean for privacy?
provn and provn-nano run on a free public upstream. Its host processes your prompts in plaintext, and Provn offers no SLA for it. Keep secrets and personal data out of prompts you send to those models.
What are Terminal's limits?
Terminal runs JavaScript in a QuickJS WebAssembly sandbox with no account. You get 12 runs per IP every 10 minutes, each with 3 seconds of CPU, 32 MB of memory and no network or filesystem. Provn pays for the runs, and every Terminal receipt is public.
What is a passport?
An opt-in public page at a handle you choose, built from your account's receipts, runs, first and last activity, and anchored receipts. The gateway signs it. It carries no trust score or quality rating and says nothing about profits or about anything done outside Provn.
Do paid plans make compute cheaper?
No. Model and sandbox prices are the same on Free, Pro and Scale, and so is the privacy contract. Pro at $29 and Scale at $99 a month raise rate limits, key counts and history retention, and add signed audit packs.
Can I recover a lost API key?
No. Provn keeps only a SHA-256 hash of the secret. Revoke the lost key in the dashboard and create a new one.
How does $PROVN relate to the product?
$PROVN will launch on Robinhood Chain, and its contract is not live yet. The API runs on a USD balance you fund with ETH, and you don't need the token to use it. The official address will appear on this page and on x.com/provn.
