A new way for BTC holders to earn yield without trading derivatives, designed from zero, for a product where people commit real capital.
OKX had strong trading and structured products, but few yield products that balanced simplicity, transparency and competitive returns. BTC Yield+ was a new structured yield product: people earn yield on their BTC through a predefined strategy, with no active trading or derivatives knowledge needed, and a BTC-native product could appeal to experienced and less-active users alike.
There was no existing UX, mental model or design precedent to build on. The challenge wasn’t a new feature. It was designing trust for a product where people commit meaningful capital.
Once the main flows were designed, we tested them in person with 16 internal users. Three screens drew the most feedback and drove the next round.
The full landing page scrolls as you move down the page. Drag to compare.
People wanted historical APRs to judge past performance. The redeem button was too hidden, and the copy didn’t make clear what they would earn.
Drag to compare.
A product logic change meant people no longer chose a tenor. The centred returns block made eyes jump around a screen that was otherwise left-aligned.
Drag to compare.
People first had to pick which bundle to redeem. A product logic change consolidated all funds into one bundle, which removed that step entirely.
A cautious BTC holder asks questions in a predictable order. The landing page answers them in that order, top to bottom, before it asks for anything.
The name, a one-line promise and the risk labels (Conservative, Principal-protected) come before anything else.
The historical average APR, labelled as reference only, never as a promise.
A performance chart shows the track record before the page asks for anything.
Holdings, available balance and total earnings, so returning users see their position first.
Three plain reasons: daily BTC rewards, principal protection and stable returns.
Four steps from subscribing to redeeming, with redemption timing and fee stated before anyone subscribes.
The FAQ covers risk, withdrawals, when interest starts and how the APR is calculated.
Subscribe and Redeem stay pinned to the bottom of the screen, one tap away at every point.
Committing capital is the riskiest moment, so the amount and review screens carry the most care.
Subscribe and redeem share one shape, so learning one teaches the other:Subscribe and redeem as first designed, before testing.
