One HTML tag puts Strike's order book inside any wallet, dApp or community. Users connect the wallet they already have with a single signature; partners earn Strike builder fees on every fill, tracked on a dashboard that checks volume against Strike's own history.
Hover a step to see what happens under the hood. Every call goes from the user's browser straight to Strike; no server ever holds a trading key.
Add the script and a <strike-trade> tag with your builder code.
<strike-trade builder-code="…">
Users pick Lace, Eternl or any CIP-30 wallet and sign once. Strike creates the account.
POST /auth/builder/verify-signature
ADA deposits are checked before signing; orders carry the partner's builder fee.
X-Builder-Fee-Bps: 5

The trading key is generated client-side and can't withdraw: withdrawals need the user's own wallet signature and only go back to that wallet.
Strike's unsigned transaction is decoded and verified: exact amount, single output, no tokens. Otherwise the widget refuses.
The fee cap is part of the message the user signs. Strike rejects any order above it, whoever the host is.
