ZKHOOD (Zerokhood)

We’ve now pushed the website live. There are just a few deposits to make so you can start testing transactions on mainnet. These are live transactions. The team has already added the deposits, so make sure to switch to mainnet so you can use the dapp properly. app.zerokhood.com/

We’ve pushed a new version of the Docker image. It’s already wired for stock trading and will be used to power the dApp that allows users to place prediction bets directly on our website. More soon. github.com/users/zkhood/pack…

We have just registered on the HACKQUEST @ArbitrumDevs @HackQuest_ @RobinhoodCrypto @arbitrum

New at ZKHood: Prediction Markets Private positions. Public odds. Real-world outcomes, starting with elections. No house, no counterparty, no one seeing your side until you claim. Every market settles from verifiable on-chain proofs, not a trusted oracle. Prediction Market and Mainnet will both go live at the same time!

We’re looking to go live with the dApp and prediction market as well. We believe in bringing a full suite of products that align with the high-quality applications that @RobinhoodApp offers!

Your order has an audience. Public mempools expose intent before settlement. MEV: documented by IEEE (Flash Boys 2.0) and flagged by ESMA.

Speed is a convenience. Math is the guarantee. Attested TEE for private speed; validity proofs for hardware-independent finality - caveats included, on @RobinhoodApp

Rebalance in the dark. Settle in the light. Your cadence and size stay private; the chain gets a proof, not a play-by-play. Status: Currently being tested.

We’re going to share a small tutorial about prediction markets, along with an update that will be released with the Mainnet push: How betting works (TEE + ZK) Place a bet: User deposits into the BettingVault with the market, amount, and Yes/No choice. Private verification: The bet details are encrypted and sent to the TEE. The TEE verifies the deposit and generates a lightweight ZK proof confirming the bet is valid, without exposing the private data. Bet goes on-chain: The ZK proof is verified and the bet is recorded on-chain. Yes/No totals are updated publicly. Market closes: Betting stays open until bettingCloseTime. The TEE is no longer needed after the bet is registered. Market resolves: A trusted resolver submits the final outcome (Yes/No/Draw). If no outcome is submitted by the deadline, anyone can cancel the market and users are refunded. Winners get paid: Users call claim(). The smart contract calculates the pari-mutuel payout and sends the funds directly to the winner. In short: Deposit → TEE verifies → ZK proof → Bet recorded on-chain → Market resolves → Smart contract pays winners.

Privacy neglect has a price tag. @IBM 2025 report: global average cost of a data breach = .44M. Meanwhile Consumer Reports + Wesleyan audit whether retailers honor opt-outs. #ZKHood

Vault custody logic: Every trade settlement now performs an unconditional solvency check before authorizing a withdrawal, ensuring no code path can leave an under-collateralized claim pending. Verified against the full Vault, rebalance, and trader-claim test suite.

Update : These three transactions demonstrate the successful operation of the application on mainnet. For this, the team pre-deposited stock tokens into the Vault to provide the liquidity required to execute the test. We then made a USDG deposit. robinhoodchain.blockscout.co… After the operation was executed off-chain inside the TEE and the zk proof was submitted, we can verify that the withdrawal was successfully released to the wallet specified by the depositor wothout linking it on chain robinhoodchain.blockscout.co… The Vault contract then performed the corresponding rebalancing through an internal swap. robinhoodchain.blockscout.co… These three transactions demonstrate that the on-chain portion of the process was completed successfully. Users will be provided with all the necessary information to independently verify, during their own transactions, that the computation was correctly executed inside the TEE, ensuring the privacy and integrity of their operations. Keep your notifications on and stay tuned, We’re on track to get the mainnet live tomorrow! barring any unforeseen delays. We’re excited to get this live!

Migration to mainnet is almost complete. We have wired the backend logic to the @RobinhoodApp mainnet network, deployed the Vault, AssetRegister, and zkRollup contracts, and already funded the Vault with real stocks. We will need these funds to complete the workflow testing and ensure the safety of the funds. For the next step, we will fund the TEE again and perform all the necessary transaction tests.

Idle capital is dead capital. Deposit cash or stock tokens into the Vault and let your assets fund private liquidity routes. Yield layer for the next generation of onchain markets, on @RobinhoodApp @RobinhoodCrypto chain.

How we maintain Compliance? @RobinhoodApp @RobinhoodCrypto

The trading flow is coming together, from oracle pricing and stock selection to private execution, ZK proofs, and on-chain settlement, from testnet to mainnet, stay tuned.

Public markets. Private strategy. Every order is encrypted and executed inside a Trusted Execution Environment, then settled with a ZK proof on @RobinhoodCrypto . Your edge stays yours.
