A portfolio is a pattern.
Cut one. Share it. Anyone can sew you back to it.
Patch is a book of recipes for tokenized markets. A recipe is a fixed set of tokens and a weight for each: forty percent NVIDIA, twenty Apple, a tenth in dollars. It lives on Robinhood Chain, under your name, and anyone can follow it from their own wallet without handing you a cent.
Following means two things. Your tokens stay in your wallet. And you give a mandate, bounded and revocable, that lets anyone rebalance you back to the recipe when prices drift or the recipe changes, for a tip. The contract checks their work at the pool's own price before and after, and throws the whole thing away if it made you worse off.
This is a wallet, not the recipe: tiles are sized by what it holds right now. Drag a tile to reweight the recipe and watch the wallet get re-sewn.
| cloth | recipe | wallet | drift |
|---|---|---|---|
| NVDA | 22% | 22.0% | +0.0% |
| AAPL | 18% | 18.0% | +0.0% |
| MSFT | 16% | 16.0% | +0.0% |
| TSLA | 10% | 10.0% | +0.0% |
| SPY | 14% | 14.0% | +0.0% |
| GLD | 10% | 10.0% | +0.0% |
| USDG | 10% | 10.0% | +0.0% |
Mandate: drift bound 3%, slippage 0.5%, tip 0.10% of what is traded. Last stitch paid its executor $0.00.
Cut a pattern
Pick up to sixteen tokens that trade against USDG here, give each a weight, name it. The set is sewn shut the moment you publish: you can change the weights forever, you can never add a token. That is what makes a mandate safe to give you.
Hand out the number
A recipe is an id in the book. Anyone with USDG can enter it in one transaction and hold the cloth themselves. A creator fee, capped at half a percent and zero by default, is cut from every purchase and every stitch.
Get stitched
Set a drift bound, a slippage bound, a tip and a cooldown. When your wallet is further from the recipe than the bound, anyone may stitch it back through Uniswap V4 and take the tip. Revoke whenever you like.
One stitch, in four squares
The executor proposes the trades. The contract does not trust them: it values the wallet at pool spot before, refuses if nothing was out of bound, caps every swap against that same spot, revalues after, and requires every tile back inside the bound with the total no lower than before less slippage, tip and fee. The full mechanism.
What is not here
- No pooled capital. There is no vault and no basket token. You hold the cloth.
- No Patch token, no protocol fee, no owner, no pause, no upgrade.
- No oracle. The pool is the price, and the risk page says what that costs.
- No manager who can move you into something you did not sign up for.
Status
The contracts are written and tested, and not yet deployed. Until they are, the patterns page is empty and this site says so. The demo above runs on invented prices.
