The vault framework

What a vault is

A vault is a named composition: a set of legs with target weights, plus a risk band. Weights are daily-rebalanced targets, when a leg outruns its weight, the excess rotates to the others. Followers deposit into their own vault share; the creator defines the composition and never touches follower funds.

Leg types

Copy

A trader’s book, a Hyperliquid vault, a top Polymarket wallet, or a disclosure tracker rebuilt from a fund’s public SEC 13F filing (quarterly weights, puts as shorts). Your share mirrors the book, scaled to your weight and band.

Fade

The same book, inverted. If the trader is reliably wrong, that is also information. A fade leg carries the same costs and the same event risk as the book it inverts.

Instrument, long or short

The asset itself, listed stocks and commodities. No trader in the loop; this is how a vault carries hedges and plain exposure alongside its copies.

Signal (planned)

A leg that tracks the top-50 cohort bias itself, long what the cohort is long, short what it shorts. Not offered yet, and it will launch with no history shown: we will not backtest a signal we did not record live. Its track record starts the day it ships. Congressional-trade trackers wait on the same rule, the free disclosure mirrors have gone dark, and we list nothing we cannot source.

Risk bands

Conservative

0.5× exposure. Band stats are re-measured on the scaled series, drawdown does not scale linearly with leverage, and the numbers shown never pretend it does.

Standard

1× exposure. Band stats are re-measured on the scaled series, drawdown does not scale linearly with leverage, and the numbers shown never pretend it does.

Aggressive

1.5× exposure. Band stats are re-measured on the scaled series, drawdown does not scale linearly with leverage, and the numbers shown never pretend it does.

How the numbers are measured

One pipeline

Every leg, live trader book, instrument, or blend, runs through the same stats code, over real trailing calendar windows. A window a book is too young for shows as unavailable, never invented.

Blending

Legs are normalized to daily fractional returns (dollar books divide by a vol-targeted bankroll: annualized $ volatility / 40%), weighted, and summed non-compounded, over the days the legs actually overlap.

The ranking

Sharpe on daily increments, scale-invariant, which is what lets percent books and dollar books share one leaderboard. Max drawdown is always shown beside it.

Listing standards

Anything can be built privately. To be listed on the public marketplace, a vault must clear the same bar we hold venue books to:

Diversification

At least two legs, and no leg above 60% of the book.

History

At least 90 days of overlapping leg history behind the blended stats.

Drawdown

Blended max drawdown within its band’s bar, a book that has given back more than half its equity is not listed, whatever its mean.

Sources

Every leg labelled live or simulated; no unlabelled history, ever.

Escrow

The creator escrows 100,000 VECTOR for as long as the vault is listed. It is returned in full on delisting; it is skin in the game, not a fee.

Lifecycle

Draft, composed and stored privately (in this build: locally on your device). Listed, public on the marketplace once it clears the standards and the creator has escrowed 100,000 VECTOR; its page shows the same measured history as any venue book. Followed, other people deposit; the creator’s changes to the composition are versioned and disclosed to followers before they apply.
