The vision
A market play that wasn't possible before.
Trustless, skill-based markets across crypto and stocks. Our tools let you safely run sophisticated prediction and trade ideas that weren't possible before. Creative reads that translate directly into rewards, onchain.
Every market, one engine
Crypto and stocks products on the same trustless rails, fully onchain and verifiable. One shared engine that every Overcall product launches on.
Products you can't find elsewhere
A whole new class of financial instruments, that are immersive, competitive, and rewarding play. Genuinely new ways to take a position, not just up or down.
Winnings priced by probability
Every multiplier reflects the market's real odds, priced from volatility and trend by a public formula anyone can check.
Trustless by design
Trust the chain, not us.
Trust should be the center point of every platform. On Overcall, prices come from decentralized oracles, every position and payout settles onchain, and the rules live in a contract anyone can read. You trade against a neutral onchain vault whose only margin is a published fee, never a hidden number inside your odds. The market decides the outcome, and every step is transparent.
A neutral vault, not a house
You trade against a public onchain vault, not a desk that profits when you lose. It takes the other side at your odds and keeps only a published fee, with no hidden edge baked into the number.
Onchain, end to end
Every position, settlement and payout is a public onchain event anyone can recompute. Even in an oracle outage it settles onchain, never trapped. Proof, not trust.
Priced by decentralized oracles
Every outcome reads a sub-second Chainlink price straight from the chain. We never touch the number, so you don't have to worry about a painted wick or a hunted stop.
Meet Channels.
Draw a channel on the live price and your payout locks in. Ride it, then close for a known amount the instant you're ready, straight from the vault. Or touch a wall and it's gone. This is the first skill-based market on Overcall, and it will not be the last.

The token
Everything runs on $OVER.
$OVER is the single asset the whole platform runs on. Every product opens and settles in it, so the platform and the token grow together.
One asset, every position
Every position, on every product, is opened and paid in $OVER, straight from the vault. The more Overcall is played, the more $OVER has to be held and moved. Demand that scales with real usage, not with a narrative.
The vault scales with $OVER
Seeded at genesis with 5% of supply, all in $OVER, the vault deepens as the token rises, unlocking bigger max payouts and more volume. That volume lifts $OVER in turn, so the platform and the token scale in proportion, both ways.
Fees deepen liquidity
Platform fees are routed into vault liquidity and trading liquidity, turning real revenue into bigger payouts and a deeper, more liquid market for $OVER.
Stake to back the vault
Stake $OVER to provide the vault's settlement liquidity and earn rewards from platform revenue. Your stake backs the payouts, and shares in the upside.

FAQ
Questions worth asking.
What is Overcall?
Overcall is a trustless platform for skill-based markets: a new class of financial product across crypto and stocks. Pioneering, immersive mechanics you won't find on any exchange, priced by decentralized oracles and settled onchain. Your read is the edge, and the outcome is provable.
How is it different from an exchange or a perp DEX?
Those resell the same old products: spot, futures, margin, perps. Overcall introduces pioneering mechanics you will not find anywhere, with your payout locked at open and paid the instant you close. Like every perp DEX you trade against a neutral onchain vault, but its only margin is a published fee, zero on testnet, never a hidden edge inside your odds.
When do I get paid?
The instant you close. Your payout multiplier was locked when you opened, so the vault settles you immediately onchain in a known amount. Ride to the end for the full multiplier, close early to keep more the closer to center, or touch a wall and lose the position.
Who decides who wins?
The market does. Every outcome reads a decentralized, sub-second price feed from the most trusted oracles. We can't paint a wick or hunt a stop, because we never touch the price. Every result is an onchain event anyone can recompute.
What can I trade?
Crypto and stocks, all on the same trustless rails, and the universe keeps growing. Every product is tailored for humans and AI agents alike.
Can Overcall cheat me or freeze my funds?
No. The code can't pick a winner, change a rule, or freeze your exit. There is no backdoor, because we never built one, and your funds can never be trapped, even during an oracle outage. It is written into the contracts, not promised in the docs.
What is $OVER?
$OVER is Overcall's token, launching on the Virtuals launchpad: liquid and community-owned from day one. It is the single asset the whole economy runs on, across every product.
Is it live? Is the money real?
The first product is live on a private testnet right now, free to play by design: you trade with free testnet $OVER, not real money. It opens to everyone soon.
