Built on Strike Builder Connect

Perps for every
Cardano app

Built for
builders

Strike's API accepts calls from any origin, so every request goes from your user's browser straight to Strike. No proxy to run, and no server ever holds a trading key.

Events your host can use

Listen for strike-session to update your own header, and strike-close to take users back to your app. It's a standard custom element in a Shadow DOM, so your CSS can't break it.

Go beyond
the trade ticket

See which of your pages bring traders, and earn your builder fee on every trade they make. Strike collects it and credits it to your account.

Attribution you can check

Credited by Strike to your Strike account on every fill. You set the fee; users approve a cap when they connect.

Builder fees on every fill

Strike lets builders charge up to 1% per fill. Add your Strike referral code to the tag to stack referral rewards on the same traders.

dApp

Hedge ADA in one click

For builders

Partner dashboard

Open

Referred wallets, funded and trading accounts, verified volume and estimated builder fees, per partner site.

Safe by
default

Trading inside someone else's website changes the trust boundaries. These are ours, stated plainly.

Keys stay in the browser

The trading key is generated client-side and never leaves it. No server, ours included, ever holds it.

The key can't withdraw

Withdrawals need the user's own wallet signature, and Strike only pays them back to that wallet.

Deposits checked before signing

Strike's unsigned transaction is decoded first: exactly the requested ADA, one output, no tokens. Anything else and the widget refuses to ask for a signature.

Fees capped by the user

The fee cap is part of the message the user signs. Strike rejects any order above it, whoever the host is.

Keys limited to the session

Strike issues keys that don't expire, so the widget enforces its own lifetime, and reconnecting rotates the key.

Isolated from the host

A Shadow DOM keeps host styles out. The known limit: a malicious host page could place trades with the in-memory key, but not withdraw. Details in SECURITY.md.

On Hyperliquid, apps that embed trading became the biggest source of builder volume. Distribution, not incentives, is what grows a perps exchange.

Strike already has the builder program. Strike On is the packaging that turns it into a growth channel.
