One day. One strike. ICHIGEKI is a non-custodial interface for daily BTC options. You connect your own wallet, pick a strike on the nearest daily expiry, see the exact premium, fees and maximum loss, and sign the order yourself. Execution, liquidity, margin and settlement are provided by [Derive](https://derive.xyz). Robinhood Chain serves as an optional wallet and funding entry point. That sentence is the whole product. ICHIGEKI does not run a matching engine, does not hold your funds, and does not make markets. ## What ICHIGEKI is * A simplified front end for Derive's existing daily BTC options order book * Non-custodial: your wallet, your Derive subaccount, your signatures * Buy-only at launch — the most you can lose is the premium you paid plus fees * Countdown-first: the exact settlement timestamp and the remaining time are always visible * BTC only at launch; ETH is coming soon ## What ICHIGEKI is not * Not an exchange. Orders match on Derive's order book; options settle on Derive Chain. * Not a Robinhood Chain-native option. Robinhood Chain is where your funds can start, not where the option lives. * Not a source of guaranteed liquidity. ICHIGEKI shows only what is actually quoted; when the book is quiet, the interface says so. * Not financial advice. ## How a trade works, in one paragraph Derive lists consecutive daily BTC options that settle at 08:00 UTC. ICHIGEKI reads that chain, keeps the strikes with live asks near the current BTC price, and shows each one with its exact premium in USDC. You choose a strike, review cost, max loss and breakeven, and sign. The order goes to Derive's book; if it fills, the position sits in your own Derive subaccount until it settles in cash at expiry. ## Where to go next * [How it works](/getting-started/how-it-works.md) — the architecture and who does what * [Funding](/getting-started/funding.md) — moving USDC from Robinhood Chain to Derive * [Daily BTC options](/product/daily-options.md) — the contract, the clock, and what "0DTE" actually means * [Risks](/security/risks.md) — read this before trading *** ICHIGEKI is a non-custodial interface. Execution, liquidity, margin and settlement are provided by Derive. Options involve risk: a bought option can expire worthless — maximum loss is the premium paid plus fees. Not available in restricted jurisdictions. Nothing here is financial advice. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.ichigeki.app/readme.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.
