Jupiter Offerbook Goes Live: The Peer-to-Peer Lending Platform That Ditches Price Oracles and Liquidations

The result is a credit market designed for collateral types that are inherently hard to continuously price, or for borrowers who want certainty that a short-term price wick won't wipe out their position.

Offerbook vs. Jupiter Lend: Two Radically Different Lending Models

Jupiter now runs two lending products that solve different problems. Jupiter Lend, which went live in August 2025, is a high-efficiency pooled money market. Offerbook is a bespoke, over-the-counter fixed-term credit platform. The distinction is architectural.

• Pool-Based (Jupiter Lend): Users deposit assets into shared pools and borrow against them. The protocol uses a proprietary liquidation engine built by Fluid to manage risk, relying on price oracles to monitor loan health continuously. Jupiter Lend famously offers up to 95% loan-to-value (LTV) ratios on supported assets and passed $2 billion in total value locked amid Solana ETF-driven inflows in early 2026 .
• Peer-to-Peer (Offerbook): There are no shared pools. Each loan is a discrete bilateral agreement. LTV, rate, and duration are fully negotiable per deal. Collateral can include NFTs and RWAs, assets that are a poor fit for oracle-dependent, liquidation-prone pool models. Counterparty risk is confined to the individual loan rather than socialized across all depositors .

The two products are complementary parts of Jupiter's expansion from a swap aggregator into what the team calls a "DeFi Superapp"—now covering swaps, limit orders, perpetuals, staking, pooled lending, and direct credit .

From RainFi Acquisition to Public Beta: The Development Timeline

Offerbook didn't appear from scratch. Its development path reveals a deliberate build-up over roughly nine months.

• August 2025 – Pooled Lending First: Jupiter launched its first lending product, Jupiter Lend, in private beta with up to 95% LTV and an automated liquidation engine . It passed $500 million in TVL within 24 hours of its public beta later that month .
• December 11, 2025 – The RainFi Acquisition: Jupiter acquired RainFi (also known as Rain.fi), a fixed-term P2P lending protocol on Solana with a community called "Droplets." The stated goal was to accelerate onchain credit market growth. RainFi had processed over 230,000 loans, and Jupiter planned to integrate its fixed-term infrastructure into its own platform. A snapshot of Droplets holders was taken on December 10, 2025, with those users set to receive JUP token rewards in early 2026 . The same week, Jupiter announced the appointment of former KKR executive Xiao-Xiao J. Zhu as its new president .
• January 31, 2026 – The Official Offerbook Announcement: Jupiter publicly announced Offerbook, describing it as "a permissionless, time-based peer-to-peer lending market for any Solana asset — including tokens, RWAs, and NFTs — without price-based liquidations" .
• Late May 2026 – Public Beta Goes Live: Offerbook opened its public beta to all users. Early reporting labeled it "DeFi lending without price oracles," emphasizing the departure from the dominant DeFi lending architecture .

The RainFi acquisition appears to have supplied both the team and the fixed-term matching logic that underpins Offerbook's core mechanics. RainFi's app was slated to continue operating independently for a few months during the full integration .

The Solana DeFi Context: Why Offerbook Matters Now

Offerbook's launch is not happening in a vacuum. It arrives during a period of high, complex activity on Solana's DeFi rails.

Solana's total value locked in DeFi protocols crossed 80 million SOL in early 2026, an all-time high measured in native units, even as dollar-denominated estimates fluctuated with SOL's price . At its April 2026 high, dollar TVL surpassed $12.3 billion, more than tripling from roughly $3.8 billion at the start of 2025 .

Lending is a major driver of that expansion. Kamino Finance leads the sector with $1.48 billion in TVL, while Jupiter Lend itself surged past $2 billion . At the same time, Solana is seeing a parallel push toward tokenized real-world assets. Orca, another Solana DEX, launched a regulated marketplace for real-world asset tokens in the same week Offerbook entered beta .

Jupiter processes more than $2.5 billion in daily trading volume as of April 2026, capturing between 60% and 70% of all Solana DEX swap volume, cementing its role as the ecosystem's anchor interface . By adding a P2P credit layer on top of its existing swap, limit-order, and pooled-lending infrastructure, Jupiter appears to be positioning itself for a market structure where not all borrowing fits neatly into a pooled, continuously monitored vault.

For assets that are illiquid, uniquely structured, or intended for a fixed-term use, the existing liquidation-dependent architecture offers no good answer. Offerbook is Jupiter's bet that direct, term-based credit fills that gap.
