What Is Rain?
Rain (RAIN) is a decentralized options and prediction-markets protocol built on Arbitrum. It lets anyone create and trade custom markets permissionlessly — a framework for options and event/prediction trading rather than a Layer-1 blockchain of its own.
How it works
Anyone can open a market. Public markets are resolved by an oracle agent (Olympus AI), while private markets let their creators act as resolvers. The protocol supports secondary trading of positions and uses account abstraction to smooth the user experience. RAIN is the protocol’s token within this ecosystem.
Risks
Options and prediction markets are high-risk by nature, and permissionless market creation adds resolution and counterparty risk — an oracle or resolver acting wrongly can affect payouts. As an Arbitrum-based protocol it carries smart-contract and L2 risk. Treat it as speculative and verify current details from the project directly.
