FAQ
What can I trade?+
Twenty-eight markets: fourteen crypto majors around the clock, and fourteen tokenized equities on their regular session. Every one uses the same contract and the same payout table.
Do I only win if the market goes up?+
No. You win on the path, not the direction. A corridor leaning down pays exactly like one leaning up if the price stays inside it, and backing a rail to break pays when the price leaves.
Can I take a position on someone else's corridor?+
Yes, that is Sideline. Every running corridor is a two-sided market priced off its own survival probability, and your ticket settles on the same outcome as the author's position.
Is Holdline my counterparty?+
A neutral onchain backstop is. It takes the other side of everything and pays every winner automatically. It does not profit when you lose beyond the published spread and fees.
What are the fees?+
An open fee of the greater of 0.8% and 0.5 $HOLD, carved out of your deposit at open. A profit fee of 9%, charged only on the part of a payout above your stake. An early-close penalty of 4% if you leave before it resolves. A published 3.5% spread sits beside the odds, never inside them.
How is my multiplier set?+
It is the inverse of your side's win probability, less the published spread, capped at x30. That probability comes from the shape you drew and the asset's live volatility, and anyone can recompute it from the signed inputs.
When do I get paid, and how much?+
The instant it resolves. A win pays stake times your multiplier, less the profit fee. An early close pays the mark-to-market value less the penalty. A loss pays zero.
How many positions can I hold?+
As many as your balance allows. There is no cap per wallet. A global exposure cap bounds what the backstop can owe at once, which can turn down an unusually large single position.
What chain is this?+
Robinhood Chain, an Arbitrum-based L2. Chain ID 4663 for mainnet, 46630 for testnet.
Do I have to verify my identity?+
No. There is no email, no password and no KYC. You connect a wallet and sign one message proving the address is yours. That signature authorises nothing else.
Are the contracts audited?+
An external audit is in preparation. Until the report publishes, treat the security properties as claims you can verify against the code rather than a third-party attestation.
Where is the $HOLD contract address?+
It does not exist yet. The address publishes in Contracts and addresses and on the landing page the moment the token generation event closes. Anything claiming to be $HOLD before then is not.
Can AI agents trade?+
Yes. Every action is a contract call plus a signed price report, the reads are a public API with no key, and the pricing model is a pure function you can run yourself.
