The wallet edition is live on Hood Chain. AUM0 now manages portfolios it cannot touch.

Contract 0xaFd484733f4B23e235bf1825c9AdA39368160B03 · Chain Hood Chain (4663) · Web aumzero.com

What changed

Custody is gone. There is no deposit and no withdraw. Your stocks and your cash stay in your own wallet, where your wallet app can see them, and every rebalance pulls, swaps, and returns the result inside a single transaction. The manager's balance is zero before the trade and zero after it. You quit by setting the allowance to zero: there is nothing to withdraw because you never gave anything up.

The venue grew from one stock to fifteen: NVDA, SPCX, TSLA, AAPL, MSFT, AMZN, MU, SPY, PLTR, SNDK, INTC, AMD, GOOGL, META, USAR. Each is pinned to its official on-chain feed and its real USDG pool, measured on-chain and frozen at construction forever.

The three walls, now on your own balances

  1. Every rebalance must move your wallet strictly closer to your target, measured before and after on your real balances, or the whole transaction reverts.
  2. Every fill is priced against the chain's official feeds, on the amount your wallet actually received, not the amount promised.
  3. No function in the contract names a destination. Swap output goes to you, the bounty goes to whoever did the work, and nothing else can move.

Live numbers, reported by the contract

drift 1479 bps -> 43 bps      bounty 0.0144 USDG
drift 9999 bps -> 305 bps     bounty 0.0969 USDG, all cash carried into
                              a fifteen-stock target in one transaction

22 unit tests pass, covering the three walls, overshoot rejection, bounty-farming rejection, bad-fill rejection, and allowance revocation. Fork suites replay rebalances against the live pools.
