Opinion is a prediction exchange that allows direct trading of macroeconomic data, predictions, and news as standardized assets. It leverages proprietary on-chain infrastructure, AI Oracle, and trading tools to democratize economic insights and risk management for retail users, institutions, and global decision makers.
Rain is a decentralized options and prediction market protocol built on Arbitrum, enabling anyone to create and trade custom markets with full on-chain transparency. It uses Olympus AI for market resolution and features a deflationary token model where trading fees buy and burn $RAIN. The protocol is governed by a DAO and aims to provide a permissionless, trustless platform for prediction and options trading.
