Key Concepts
Plain-English definitions for every term you will meet on Zirodelta. Each one answers: what is it, and why does it matter to you.
Programmable personal balance sheet
The category Zirodelta builds. Every product in the system moves one of four lines of your personal balance sheet: assets, liabilities, income, liquidity. The loop you live inside keeps every dollar moving, from earning to collateral to spending and back to work, so none of it sits idle (see the diagram in What is Zirodelta?). Earning is in its proving phase today; the collateral (borrowing) and spending legs are in development.
The Zirodelta Financial Engine
The platform behind Zidee: the Yield Engine, Credit Engine, Conversion Engine, Settlement Engine, Treasury Engine, Referral Graph, and Fiat Rails. The Yield Engine is the first part running, in its proving phase; the rest are in development. Zidee is the first client of this engine, not the engine itself.
Zidee
The wallet that lets you use your programmable personal balance sheet. Non-custodial, mobile-first, at wallet.zirodelta.com. See Zidee Wallet.
ZDLT
Access and alignment: a token that pays you to stay. Fixed supply (no new tokens are ever minted), mint and freeze authority revoked, 0% allocated to the team. You hold it in Zidee and are paid rewards in wzdUSD, never in ZDLT. "Pays you to stay" refers to wzdUSD rewards, never to token price. See ZDLT Overview.
wzdUSD
The working dollar of the balance sheet, and the dollar you are paid in. wzdUSD is a yield-bearing dollar that appreciates over time, more like a liquid-staking token than a stablecoin. It is not pegged to $1, and we never call it one: it is backed, but market-priced, and can trade a little above or below its backing. See wzdUSD.
Tiers and lock multipliers
How "paid more the longer and the more you hold" is made concrete. Holding ZDLT places you on a tier ladder named after the stars of Orion (Mintaka up to Saiph); holding longer adds a multiplier. Together they decide how large your share of the reward pool is. Tiers are reward multipliers, not trading limits. See Tiers.
Funding rate
A periodic payment between the long and short sides of a perpetual futures market. When the perp trades above spot, longs pay shorts; when below, shorts pay longs. The Yield Engine earns this payment. You never touch it directly. See Funding Rates on Hyperliquid.
Delta-neutral
A position with zero net exposure to price. The Yield Engine holds a short perp and an equal long spot in the same asset, so price moves cancel between the two legs and the only income left is the funding payment. This is what lets the reward pool earn yield without betting on price going up or down. It reduces risk; it does not remove it. See Delta-Neutral Explained.
The Yield Engine
The delta-neutral funding strategy on Hyperliquid, part of the Zirodelta Financial Engine, that funds the reward pool. It is real, it is variable, and it is currently being proven on the founder's own capital first. See Yield Engine.
The pool's trading key
How the Yield Engine trades without ever being able to move money. The Engine runs one delta-neutral position for the whole pool, and the key the server signs with has order authority only: it can open and close the pool's orders, and it physically cannot withdraw or transfer. The key that could move funds out of the pool is held off-server, and your own funds stay under your own keys. See Custody.
Proving phase
Where the product is today. Before user money is accepted, the strategy runs on the founder's own capital on a public address, so the track record is built in the open. The vault that backs wzdUSD stays closed to user funds until an independent security audit and a legal review are complete.
The Vault
What backs wzdUSD and, in time, holds the strategy's collateral. It is unaudited and closed to user money for now; it opens only after audit and legal review. See Vault Overview.
