ZK proof-of-performance · Robinhood Chain
Publish a trading performance card anyone can verify — without anyone seeing your trading wallet address.
SHOW THE SCORE. HIDE THE WALLET.
Proves
An indexer-attested result clears a threshold — on the registered market, in the registered season.
Non-custodial
The MVP never holds trader funds and never trades on your behalf.
No token required
$OFFS is a proposed ticker. You can use the product without holding any token.
7 days. One market.
Rules locked in advance.
Four steps. The wallet stays offscreen.

The card is the object. Not a spreadsheet.
The 1200 × 675 share card says exactly what was proven. No exact PnL figure, no trading address.

STEP 1 / 6
Connect trading wallet
This is the wallet you trade with during the season. Only the attestor sees this address — it never appears on the public card. Works with any browser wallet — MetaMask, Rabby, Coinbase Wallet, OKX and more.
Required networkRobinhood Chain Mainnet · 4663
STEP 2 / 6
Sign the registration challenge
The signature proves you control the wallet. The secret never leaves your browser — only the secretHash is sent over a private channel.
{{ l.k }}{{ l.v }}
STEP 3 / 6
Back up secret
Your secret was generated randomly in the browser. Download a password-encrypted backup (AES-GCM, PBKDF2).
If you lose the secret after registration locks, there is no new secret for this season. There is no server-side “recover” button.
STEP 4 / 6
Wait for season close and finality
Registration is locked. After the season closes, the indexer reads every block, the attestor publishes the Merkle root onchain, and you receive your record and Merkle path via an authenticated API.
{{ c.t }}{{ c.s }}
STEP 5 / 6
Generate proof locally
A Groth16 proof on BN254 is generated in a Web Worker. Predicate: eligible = 1, at least 2 swaps including a buy and a sell, PnL > 0.

STEP 6 / 6
Publish card
Choose how to submit the proof. profileController is a publishing wallet separate from your trading wallet; relaying the proof cannot change the card owner.
SUBMITTED · SIMULATION
Card published.
Receipt OFS-S04-NEW1 is immutable. Anyone can verify it without connecting a wallet.
This card only attests PnL from trades in the registered market. It implies nothing about portfolio PnL, USD profit, or future profitability.

Verify
Paste a receipt ID. This page reads the root and verifier directly from the chain and reports four separate results: valid math, accepted root, matched context, and environment.
Try:

{{ verdict }}
mathValid
The Groth16 proof is valid for the public inputs.
rootAccepted
Root published by the attestor, final, not revoked.
contextMatched
Season, rulesHash, predicate and domain match.
environment
Simulation, Verified Testnet or Verified Mainnet.
Rules
Narrow enough to implement correctly, clear enough for anyone to read. PnL is computed in the quote asset's smallest unit, using integers.

Trust model
WHAT ZK PROVES
A record belongs to a Merkle root registered onchain and satisfies the predicate — without revealing the record.
STILL TRUSTED
The indexer and attestor compute the metric. A faulty or dishonest attestor could still issue a wrong metric.
PRIVATE FROM WHOM
From public viewers. The attestor sees the wallet address and history. Underlying onchain transactions remain public.
