Offerbook is a permissionless, peer-to-peer money market for any onchain assets on Solana. It allows users to borrow or lend at fixed rates, for a fixed period of 3 days, using onchain assets as , without price-based liquidations and without relying on price oracles. Unlike classical lending protocols, Offerbook is built around time-based loans. Risk is managed by duration, not by collateral price fluctuations. Both borrowers and lenders can publish offers with their own terms, expressing their intentions openly in the offerbook. Lend offers are available for 24 hours, borrow offers for 1 to 7 days (set by the borrower). Expired offers can be renewed without recreating them.

​
In Other Words

Offerbook is best understood as a fixed-term credit market. Every loan has a known duration, a known return, and a known outcome at maturity. For lenders, returns are driven by three variables: collateral quality, loan duration, and . For borrowers, it means full control over loan terms and no price-based liquidations.

Borrowers can

  • Create borrow offers with custom terms
  • Accept existing lend offers
  • Use any supported onchain asset as collateral
  • Repay at any time before maturity

Lenders can

  • Create lend offers with custom terms
  • Accept existing borrow offers
  • Accept offers partially or in full
  • Earn fixed yield over a known duration
Partial acceptance is available for all offers except those using NFT collateral, since an NFT cannot be partially transferred.

​
Escrow Wallet

When using Offerbook, all funds transit through a dedicated escrow wallet, separate from your main Solana wallet. Each user has one escrow wallet.
The escrow wallet is visible in the interface alongside your main wallet balance. Lenders deposit USDC into the escrow before creating offers.The escrow system allows lenders to create multiple offers using the same USDC balance. All offers are visible at the same time. When one offer is accepted, the USDC leaves the escrow, and any remaining offers that are no longer covered by the balance are hidden automatically.Funds remain in the escrow until an offer is accepted. You can deposit and withdraw at any time.

​
Why Offerbook?

USDC is the only asset that can be borrowed or lent on Offerbook. This simplifies the experience for both sides: borrowers and lenders only need to choose the collateral asset and the loan terms. Offerbook can be used with any Solana asset as collateral, and is optimized for specific use cases:

Fixed-term loans

Simple loan management with predictable terms, duration, and outcomes.

Illiquid assets

High-value assets with low onchain liquidity (such as RWAs) can be used as collateral without price-based liquidation or price manipulation risk.

Advanced DeFi assets

LP positions, PT tokens, and other complex assets can be used as collateral.
On the lending side, Offerbook provides a way to earn yield at fixed terms, with clearly defined risk at loan maturity.

Offerbook vs Jupiter Lend

Offerbook and Jupiter Lend are both lending products within the Jupiter ecosystem, but they serve different use cases and operate on different models.
ParameterDetail
ModelPeer-to-peer. Borrowers and lenders publish offers expressing their intentions, and are matched directly through an order book.
RatesFixed. Set by the user at offer creation and locked for the full loan duration.
Loan durationFixed at 3 days. Starts when the offer is accepted, not when it is published.
If not repaidAfter maturity, the lender can claim the collateral. The borrower can still repay until the lender claims. No price-based events during the loan.
OraclesNone. Prices in the interface are informational only.
Collateral monitoringNone during the loan.
Borrowable assetsUSDC only.
CollateralAny Solana asset (verified tokens, RWAs such as xStocks).
Use Offerbook when you want fixed terms, no liquidation risk during the loan, or need to borrow against assets with low onchain liquidity. Use Jupiter Lend when you want flexible, perpetual positions with continuous collateral monitoring and variable rates.

​
Use-Case Example

Borrowing against a high-value onchain asset: A user holds a tokenized onchain asset valued at approximately $10,000, with limited onchain liquidity. Rather than selling the asset, this user wants to access USDC liquidity for a short period. He creates a borrow offer on Offerbook with the following terms:
ParameterValue
CollateralOnchain asset valued at ~$10,000
Borrowed asset8,000 USDC
LTV80%
Loan duration3 days
Fixed APR35%
A lender accepts the offer. Once the loan starts, the collateral is locked for 3 days, and the borrower receives 8,000 USDC. During the loan, no price-based liquidation can occur, regardless of market price movements.
At maturity, the borrower repays the borrowed amount plus interest:
ItemAmount
Interest paid~$23 for the 3-day loan
Fee at loan start (25% of estimated interest, paid by borrower)~$5.75
Fee at repayment (10% of interest, deducted from lender’s return)~$2.30
Interest received by the lender~$14.95
The loan is closed, and the collateral is returned directly to the borrower’s wallet.
