Put stock tokens to work

The product is deliberately narrow. Uptick does not pick stocks, lend them out, or take a directional position. It provides liquidity in one pair, holds the range it was given, and reports the result of a replay that anyone can inspect.

The three parts

A vault is the visible part of three systems. The evidence engine decides whether the pool is worth a vault and how large it can be. The contract holds the position and prices every entry and exit. The keeper moves the band and serves the evidence that the app and agents read.

What a vault holds

Every vault holds the same three things: idle balances of the Stock Token and USDG, both legs of a Uniswap v3 position, and fees earned but uncollected. Shares are priced in the Stock Token, so the share price rises as fees accumulate and falls when the position loses to informed flow.

How the gate decides

The gate is a replay measurement, not an opinion about the token. A 30-day window of swaps runs in two halves: the first 15 days select the pool, and the second 15 days are held out. The weaker half decides the state. A vault needs net fees at or above break-even in both halves to open.

Where the numbers come from

The universe starts from 3,357,382 replayed swaps over 30 days. Each vault gets the largest position that stays at or below 20% of in-range liquidity, under a $100,000 ceiling. A pool whose depth would carry less than $10,000 is left out; a pool between that floor and the ceiling gets the largest size it can carry. The fee APR and kept APR you see on a vault page are the replay outputs for that size.

const base = "https://uptick-evidence.earn-shield-alerts.workers.dev";
const vaults = await (await fetch(`${base}/vaults`)).json();

for (const vault of vaults) {
  console.log(vault.id, vault.open, vault.deposit_cap_usd);
}

const nvda = await (await fetch(`${base}/vaults/nvda`)).json();
console.log(nvda.open, nvda.kept_apr_pct, nvda.pools.length);

The list carries each vault's open flag, deposit cap, fee APR and kept APR. The per-vault response adds the name, token, feed and the pool table the choice came from. The open flag is the gate's verdict; kept APR is the held-out half it was measured on.
