See it

The app's own screens. Real strategies and real rates; the balances are a demo account. Swipe, or use the arrows.

Sign-in screen: three strategies with the yield each returned over 30 days, the protocol behind each and the day it was measured — Sign in. What the strategies pay is on screen before you type anything.

The one-time code step, four of the six digits entered — A one-time code by email. No password, no seed phrase.

Home screen: the total balance, how much of it is working, how much is free, and the open positions underneath — Home. What you hold, what is working, what is free to move.

Earn screen: a ring showing what share of the balance is working, with earned, average rate and available beside it — How much of the balance is working — and what it averages.

The Safe tier of the strategy list: Steakhouse at 5.34% and Gauntlet at 6.00% a year, each with the firm that runs it — Every strategy we can enter, with its 30-day rate and its manager.

The Aggressive tier of the same list: Avantis at 9.01% and Arcadia at 8.50% a year — Three risk tiers. The same catalogue, re-rated.

Steakhouse High Yield USDC: 5.34% over 30 days, 5.25% over six months, where the yield comes from, and every fee — A strategy card: where the yield comes from, and every fee.

The Add funds sheet, with the unwrap step struck out as not needed — Topping up a position you already hold, priced the same way.

Avantis USDC Vault: 9.01% over 30 days, marked aggressive, with its yield source in one sentence — The high-yield end of the catalogue, dated the same way.

The Enter strategy sheet: the amount, where the money comes from, and the batch it will send — One tap in — after the whole cost is broken out.

The same sheet scrolled to what reaches the strategy and the projected yearly yield — Entry fee, what reaches the strategy, gas sponsored.

An open Steakhouse position: its value, its net return, what was invested, and every entry that built it — A position: what it cost, what it is worth, what it returned.

The Gauntlet position, read from the same catalogue in the same shape — The second position, in the same shape.

The Exit sheet: the amount out, the profit inside it and what reaches the wallet — Leaving: the profit, our 10% of it, what lands in your wallet.
