Rain Protocol (RAIN)

Rain Protocol is a modular development framework on the Arbitrum chain that enables the creation of prediction markets and options applications.

It provides developers with a full set of tools to build their own markets - SDKs, APIs, and smart contracts. Rain prediction markets Arbitrum also offer several advanced features to enhance the user experience, including the ability to make markets private or public, native token support, and AI-powered automated resolution.

Additionally, the recent Rain x Openclaw integration allows users to provide context directly to Openclaw via the Rain SDK and essentially vibe-code markets without solid coding knowledge.

This lets creators focus on user experience rather than infrastructure, customizing apps for specific audiences, introducing new features, and earning a share of revenue generated through their markets.

The model is similar to Hyperliquid's HIP-3, where the platform provides its own interface and infrastructure that creators use to build their own DEXs on top of it, with revenue split between the creator and Rain Protocol Arbitrum prediction markets.

🪙 Rain protocol token: Launched on August 26, 2025, $RAIN is the platform's native token used for governance, regular token buybacks, accessing Trading Power for leveraged prediction market trading, and paying rewards to creators and contributors.

In May 2026, $RAIN token entered the top 20 coins by market capitalization following a $100M liquidity commitment ahead of the V2 launch and World Cup expansion. It has also become a top-3 prediction market by TVL and fees, according to DeFiLlama.
