Bellswap Open a BTC ticket

Options as simple as a perpetual position, with no liquidations.

A ticket goes long or short at a multiple up to 100x on BTC, risks only its USDG stake, and settles at one Pyth price at expiry on Robinhood Chain.

FAQ

Where does the price come from?

From Pyth. One Pyth price at expiry settles the ticket. There is no liquidation price.

Who takes the other side?

One open vault takes the other side of every ticket. It sets aside the full payout at open, earns the fee and what losers leave, and pays what winners take.

What is the most I can lose?

The USDG stake. A ticket with a 20 USDG stake has a worst case of 20 USDG, and no liquidation price exists.

What runs on mainnet and on the testnet?

Mainnet: BTC tickets on Robinhood Chain, 2x to 100x. Testnet: all 407 Pyth markets on Robinhood Chain testnet, multiples up to 20x, no ETH needed.

Can anyone add USDG to the vault?

Yes. Anyone can add USDG to the vault and remove it later. The vault earns the fee and what losers leave, and pays what winners take.

Is there an audit?

No. I test in prod, and my own money went into the vault first. Use it at your own risk. Code: github.com/bellswap/clamp
