What is Rain in practice is the native token of Rain Protocol, a decentralized prediction-market platform built on Arbitrum, an Ethereum Layer 2 network. The token, RAIN, is separate from Rain (rain.xyz), a stablecoin card company founded in 2021 with no confirmed link to the token. At the time of the market snapshot, RAIN traded at $0.006191, down 1.50% over 24 hours and 23.69% over seven days. Its market capitalization was $4.40B (rank #33), and it was 68.19% below its all-time high of $0.01946.
Core technology and blockchain architecture
RAIN is an ERC-20 token on Arbitrum One with the contract address 0x25118290e6A5f4139381D072181157035864099d. The whitepaper describes the token contract as non-upgradeable. The protocol handles market creation, trading, liquidity and settlement on-chain. Prices are set by an automated market maker based on the share of liquidity allocated to each outcome.
Version 2 adds on-chain order books, and the project homepage shows "V2 Live on Arbitrum." Deposits are supported from Base, BNB Network, Ethereum and Arbitrum, according to the rain.one FAQ.
Primary use cases and real-world applications
- Public and private markets: Anyone can create markets on verifiable events without approval. Public markets are resolved by Delphi, an AI oracle developed by Olympus AI, with disputes escalated to human oracles. Private markets can be resolved by their creator.
- Builder tools: An SDK lets developers launch independent prediction-market platforms and earn a share of the volume they generate. A $5 million grant program was announced on 20 March 2026, with grants of up to $50,000.
- Aggregation: The Pred app is described as an aggregator for every market built on the protocol.
Who is behind Rain and where is it based?
The legal entity behind the token is The Rain Foundation, a non-profit foundation registered in Panama on 14 July 2025, with its registered address in Panama City. The whitepaper names Lorena Del Carmen Diaz Moreira as founder, Ana Gabriela De Leon Macias as president and Rebeca Isabel Munoz Arosemena as secretary. These are foundation officers. The sources do not establish them as software developers, and Panamanian law governs the token.
The protocol's development team is less clear. LinkedIn profiles list Roy Shaham as CEO and Muhammad Wasif as CTO, but CoinStats states that the original founders and complete engineering team are not publicly confirmed. The founding year is given as 2024 by LinkedIn and IQ.wiki and as 2025 by other sources. RAIN trading began on 24 March 2025, according to the whitepaper. Press releases are datelined Panama City, but the sources do not name a single headquarters country for the protocol team.
Tokenomics
Supply
The snapshot lists a circulating supply of 710,828,835,436 RAIN and a total supply of 1,142,404,660,749 RAIN. The whitepaper gives an initial supply of 1,150,000,000,000 RAIN and states that this is not a maximum, because of its inflation mechanics.
Allocation figures conflict across sources. DeFiLlama groups supply as insiders 37.1%, liquidity 24%, ecosystem 24% and private sale 14.8%. The whitepaper sets out separate categories, including a team allocation of 10% with a one-month cliff followed by 24 months of linear vesting. According to CryptoTicker, about 431.6 billion tokens remained locked as of 27 October 2026. DeFiLlama reports no upcoming unlocks as of 28 October 2026.
Inflation and deflation
Under the whitepaper, 2.5% of trading volume in every market is used to buy RAIN on the open market and burn it, a mechanism the whitepaper describes as discretionary. An amount equal to 10% of tokens burned through buybacks is minted as dynamic inflation for ecosystem growth, team incentives and marketing.
On 25 August 2026, the protocol burned 7,419,354,838 RAIN from its first DAO Credit Refund settlement, equal to 1.035% of circulating supply.
Consensus mechanism and network security model
RAIN has no independent consensus mechanism. It inherits security from Arbitrum, an optimistic rollup that anchors transaction data to Ethereum's proof-of-stake layer. Transactions are assumed valid by default, and fraud proofs resolve disputes.
The token contract passed an audit by Hacken with no critical or high-severity findings, according to the whitepaper. A protocol-level audit is listed as an upcoming milestone. Upgrades and treasury actions are controlled by a Foundation multisignature structure, and the whitepaper states that governance is not yet decentralized. Market outcomes depend on the Delphi oracle, which rain.one reports as 96% accurate.
Key partnerships and ecosystem integrations
- Exchanges: KuCoin announced its listing on 6 January 2026, Kraken made RAIN available for trading on 9 February 2026, and Gate listed it effective 24 June 2026. The whitepaper also lists MEXC, BingX, BitMart, WhiteBit, LBank, XT, Bitrue, BloFin and Gems Trade. The token was initially distributed through Gems Launchpad.
- Enlivex: The Nasdaq-listed company Enlivex (ENLV) held 79,568,550,005 RAIN as of 27 May 2026, according to an SEC filing. On 22 September 2026, Enlivex announced the termination of a securities purchase agreement with the Rain Foundation that had been payable in RAIN tokens.
Competitive advantages and unique value proposition
Rain positions itself as a permissionless alternative to closed prediction-market platforms. Its distinguishing features, as described by the project, are market creation without approvals, AI-assisted resolution with human dispute escalation, a buyback-and-burn tied to trading volume, and an SDK for AI agents. The company claims the protocol is the third-largest prediction market by total value locked, behind Polymarket and Kalshi. This claim has not been independently verified. The homepage shows a TVL of $97.30M and 38.14K total active users, figures that are self-reported and undated.
Current development activity and roadmap
- 26 May 2026: Rain committed $100 million in liquidity ahead of V2 and the FIFA World Cup, split into $50 million in USDT and $50 million in RAIN.
- June 2026: V2 was announced with automated market makers, on-chain order books and AI-assisted resolution.
- September 2026: SDK v2 launched on Arbitrum One, replacing the original SDK.
The whitepaper lists the following upcoming milestones: completion of the protocol audit, integration of additional blockchain networks, enhancement of the oracle and dispute framework, and DAO-based governance, whose timing is "not yet finalized." No GitHub activity for the current product was verified in the sources.
