Rain

Description sourced from DeFiLlama's protocol metadata; teams submit their own copy when listing.

DeFiLlama publishes the exact rules used to aggregate on-chain balances into the headline TVL figure shown on this page. The methodology below is the team's own source-of-truth description.

TVL includes all markets created on rain.one platform.

If a contract or vault isn't in this list, its balance does not contribute to the TVL displayed on Mantapex or DeFiLlama.

Rain's governance or utility token carries a market capitalisation of $4.2B based on circulating supply at the latest DeFiLlama snapshot. The market is pricing the token ($4.2B) above the protocol's on-chain TVL ($4.2M) — a mcap/TVL multiple of 1003.70× implies investors are paying for expected future fee flows rather than current deposits alone.

Market cap and supply figures are sourced from DeFiLlama's price feed (which reconciles CoinGecko, CoinMarketCap, and on-chain DEX prices). Treasury and staking values reflect on-chain balances controlled by the protocol at last sync.

Rain is a Prediction Market protocol where traders open leveraged, perpetual, or option positions priced off oracle feeds and settled in collateral held by the contract. It is deployed on Arbitrum. The codebase has been independently audited (1 report on file).

Rain is a single-chain protocol, deployed exclusively on Arbitrum — this concentrates execution risk but simplifies the trust model. Only one audit report is currently listed; users should weigh that against the protocol's TVL before depositing significant amounts. Its token market cap ($4.2B) currently exceeds total value locked ($4.2M) — a mcap/TVL ratio of 1003.70 suggests the market is pricing in more growth than current deposits support.
