Prediction Markets Protocol — Rain

Rain is the engine behind the next generation of forecasting. We empower creators and AI agents to architect their own prediction markets platforms.

Legereum designed and built the full smart contract infrastructure for Rain — a decentralized prediction markets protocol on Ethereum. The protocol reached $4M+ in Total Value Locked within weeks of launch, with 12,000+ active wallets and zero security incidents. Our scope included Solidity smart contracts, Hardhat test suites, a gas-optimized liquidity model, and a DAO governance module. All contracts were internally audited with a full audit trail.
