Today it is where you **hold ZDLT**; rewards, paid in **wzdUSD**, begin once the Yield Engine graduates its proving phase. It is a Progressive Web App at [wallet.zirodelta.com](https://wallet.zirodelta.com), install it to your home screen and it behaves like a native app. There is also an Android app. You log in with Discord or email and hold ZDLT; once rewards go live they accrue to you in [wzdUSD](/zdlt-token/wzdusd.md), the working dollar. No trading, no order books, no perp mechanics to learn. ## What Zidee is A clean, non-custodial home for your balance sheet, starting with ZDLT: * **Login:** Privy authentication (Discord or email). No seed phrase to write down at sign-up; Privy holds your master key inside a Trusted Execution Environment, and you can export it whenever you want. * **Holdings:** one screen for what you hold, ZDLT, USDC, and SOL on Solana (plus balances used to fund and move in). Tap any token for its detail screen. * **Swap to ZDLT:** in-app swap powered by Jupiter. Convert SOL or USDC into ZDLT in one tap. * **Send / Receive:** QR and address for ZDLT, USDC, and SOL. Every transfer is signed by your own key on the device; the server never sees it. * **Buy:** fund with crypto today, or with a card where supported (Privy onramp). * **Activity + price:** recent on-chain transfers per token, and a daily sparkline so you can read the trend. Zidee is built toward one balance that earns, borrows, and spends. Earning is in its proving phase (below); borrowing against your balance (the Credit Engine) and spending through fiat rails are in development. ## How you earn You hold ZDLT, and you are paid in **wzdUSD** for holding. You are paid more the longer and the more you hold (see [Tiers](/zidee-wallet/tiers.md)), and you are never paid in ZDLT, so holding is never diluted. The reward is funded by a real, market-neutral strategy, [the Yield Engine](/the-zirodelta-financial-engine/overview.md), part of the Zirodelta Financial Engine, not by new deposits and not by printing tokens. It is **variable and never guaranteed**: it can be low or even zero. The strategy is being proven on the founder's own capital first, on a public address, and the deposit-and-earn flow opens to user funds only after an independent audit and a legal review. ## Who it is for * **Holders who want to be paid for holding,** without learning a trading terminal. * **People who want their crypto on their phone,** installed as a PWA, same surface across devices. ## Is it safe? Yes, by construction. Your master key lives in Privy's TEE and is yours to export. No key Zirodelta holds can withdraw your funds: the trading key can only place orders for the strategy (Hyperliquid enforces that boundary, not a Zirodelta promise), and the policy-locked bridge signer can only forward your USDC along the one route you approved. See [Custody](/zidee-wallet/custody.md) for the exact split. ## How to get started 1. Open [wallet.zirodelta.com](https://wallet.zirodelta.com) on your phone. 2. Log in with Discord or email. 3. Add USDC, swap into ZDLT, and hold.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.zirodelta.com/zidee-wallet/overview.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
