Lock stock
Deposit a tokenized stock into the protocol. It stays on chain, in your series, and it is what covers the call you are about to write.

Stocks are the asset.
Options are the strategy.
Holding a tokenized stock is one position. Bitstock adds the other one: lock the stock, name a strike, an expiry and a premium, and someone takes the other side. Every contract is covered by collateral already sitting in the protocol — contract for contract, no margin calls, no liquidations.

Put your stock to work
Write the call
Choose the strike, the expiry and the premium that fit your view. Your offer sits on the book until somebody takes it, and you can pull back whatever is unsold.
Earn the premium
The buyer pays it the moment they fill your offer, straight to your wallet. The locked stock covers the position until expiry.
Two sides. One market.
Settlement
European
One price, at expiry, from the same Chainlink feed the market is quoted on.
Collateral
100%
Stock for a call, cash for a put. Locked before the offer is on the book.
Protocol fee
1%
Of the premium only, capped at 2% in the contract. Half of it streams to BITS stakers.
