Task

Goal: Design and build a simple options wizard to help traders buy calls and puts on Derive based on a price target within a timeframe.

The options wizard should have the following features:

• Select a currency (ETH or BTC)
• Select an expriy
• Select a strike
• Show a recommended instrument (e.g. ETH-20250228-1000-P)
• Show the best bid/ask price of the instrument

A demo of a complete solution is shown below:

What We Are Looking For

• Reliable, efficient code. First and foremost, Derive is a high performance trading interface. Your solution be fast and work without bugs.
• High quality design. We have provided a barebones design system in the repo and demo, but you are encouraged to extend it to create excellent UX and interactions.
• Above and beyond. We are looking for engineers who care deeply about their work and go the extra mile to create awesome experiences for users.

Installation

yarn install
yarn dev

Stack

• TypeScript
• NextJS/React
• Tailwind for styling
• Shadcn for ui components

Important Notes

• Khan Acadmey has a helpful introduction to options.
• We are only interested in ETH and BTC currencies with options markets. Other currencies, like SOL, do not have options markets on Derive and should be filtered out.
• Currencies (ETH, BTC) have many expiries (Feb 12, Mar 18). Expiries have many strikes ($2000, $3000). Every strike has a call and put option. An instrument is the combination of a currency, expiry, strike and call/put. The unique identifier for an instrument is the instrument_name, e.g. ETH-20250228-1000-P
• Not all expiries have all strikes. For example, the Dec 21 expiry can have the $10000 strike when the Feb 12 expiry does not.
• For the purposes of this options wizard, if the strike price is greater than the spot price, we expect the price to go up and should buy a call. If the strike is lower than spot, we expect the price to go down and should buy a put.

Derive API Reference

We have included functions to call the necessary Lyra API endpoints to complete the challenge. These are wrapped as:

fetchAllCurrencies()

• Gets all active currencies on Lyra with their spot price

fetchInstruments(params)

• Gets all active instruments for a given currency and type

fetchTicker(params)

• Gets a ticker for a specific instrument, including the best bid and ask price

You can access the API documentation for more details on the request parameters and respective response body.
