Overview

LIME is a continuous payoff market protocol for trading quantitative future outcomes.

What LIME is

LIME stands for Linear Index Market Exchange. It lets users trade Markets whose payout moves continuously across a defined range instead of resolving to a simple yes or no outcome.

A Market might track an interest rate, commodity price, inflation print, temperature value, or any other observable metric with clear bounds and a resolution source.

Core idea

If a resolved value lands halfway between a Market's lower and upper bounds, the linear payoff ratio is 50%. Long Positions receive that ratio and Short Positions receive the complement.

System shape

The MVP keeps user interaction, off-chain matching, and Solana custody separated. The browser signs intent, the Backend owns the Order Book, and the Programs own protocol state that must be enforceable on-chain.
