P2P Lending Explained: From Marketplace Loans to DeFi Peer-to-Pool
How peer-to-peer lending started, why the marketplace model hit its limits, and how DeFi reinvented it as peer-to-pool lending on JewelSwap across MultiversX and Sui.
Peer-to-peer lending promised something simple and radical: let people lend directly to other people, cut out the bank, and share the interest that banks used to keep. For a decade, marketplace lenders chased that promise. Then decentralized finance took the same idea on-chain and rebuilt it from scratch. This guide walks through how peer-to-peer lending started, where the marketplace model hit its limits, and how DeFi reinvented it as peer-to-pool lending — the model JewelSwap uses today across MultiversX and Sui.
What is peer-to-peer lending?
P2P lending is a way for individuals to borrow and lend money without a traditional bank sitting in the middle as the counterparty. Instead of depositing your savings with a bank that then decides who to lend to, a peer-to-peer platform connects you — the lender — more or less directly with a borrower, and you earn the interest they pay.
The classic version of this is the marketplace model, made famous in the 2000s and 2010s by firms like LendingClub, Prosper, and Zopa. The mechanics looked roughly like this:
- A borrower applies for a loan and is assigned a risk grade.
- The platform lists that loan request on a marketplace.
- Lenders browse listings and choose which loans (or fractions of loans) to fund.
- Once fully funded, the loan originates, and repayments flow back to lenders over time.
For a while this felt like the future of finance. Savers could earn more than a bank deposit paid, borrowers could sometimes get cheaper credit, and the platform earned a fee for running the marketplace rather than taking on the loans itself.
The limits of the marketplace model
The marketplace approach was a genuine innovation, but it carried structural frictions that never fully went away. Understanding them is the key to seeing why DeFi went in a different direction.
Credit risk sits with the lender
In marketplace P2P, loans were typically unsecured or lightly secured. If a borrower defaulted, the lender absorbed the loss. Risk grades helped, but they were estimates based on credit history, and lenders were ultimately betting on a stranger's willingness and ability to repay. During stress periods, default rates could climb faster than the advertised yields suggested.
The matching problem
A marketplace only works when both sides show up. Lenders had to find loans worth funding; borrowers had to wait for enough lenders to fill their request. Capital could sit idle waiting to be deployed, and borrowers could wait days for a loan to fully fund — or see it expire unfunded. This matching friction is inherent to any model that pairs a specific lender to a specific borrower.
Custody and trust
Despite the "peer-to-peer" branding, the platform still held the money, ran the books, and controlled the flow of funds. Lenders had to trust the operator's underwriting, its servicing, and its solvency. Several marketplace lenders pivoted toward institutional funding or became more bank-like over time — quietly walking back the original peer-to-peer vision.
The core tension: true peer-to-peer matching is slow and manual, while making it fast and liquid tends to reintroduce the very intermediary P2P was meant to remove.
How DeFi reinvents P2P lending
Decentralized finance rebuilds lending on public blockchains using smart contracts instead of a company's back office. If you are new to the concept, this overview of DeFi is a useful primer. The crucial design shift is that DeFi lending is usually peer-to-pool rather than peer-to-peer.
Instead of matching one lender to one borrower, a peer-to-pool protocol works like this:
- Lenders deposit assets into a shared liquidity pool governed by a smart contract.
- Borrowers draw from that pool instantly by posting collateral worth more than they borrow.
- Interest paid by borrowers accrues to the pool and is shared among all depositors.
- Everything — deposits, collateral, interest, liquidations — is enforced by transparent, auditable code.
This single change quietly solves most of the marketplace model's problems:
- No matching wait. Borrowers do not wait for a specific counterparty to fund them. If the pool has liquidity, the loan is available immediately.
- Collateral replaces credit scoring. Because loans are overcollateralized on-chain, lenders are not underwriting a stranger's payslip — they are protected by assets locked in the contract and by automated liquidation if collateral value falls too far.
- Non-custodial by design. Funds live in smart contracts, not a company's bank account. Rules are visible on-chain, and no operator can quietly change who gets paid.
JewelSwap's peer-to-pool model
JewelSwap is a multi-chain DeFi protocol built on MultiversX, Sui, and Radix. Its lending products are non-custodial and follow the peer-to-pool approach — lenders supply liquidity and earn yield, while borrowers take instant loans against collateral without hunting for a counterparty.
For lenders: deposit and earn
Lenders deposit into JewelSwap's pools and start earning yield from the interest borrowers pay. There is no listing to browse, no individual loan to hand-pick, and no idle capital waiting to be matched. Your deposit becomes part of the shared pool that backs live borrowing demand, and because everything settles on-chain, you keep custody of your position rather than handing assets to an operator.
For borrowers: instant loans against collateral
JewelSwap borrowers post collateral and draw a loan immediately, as long as the pool has liquidity. The protocol supports several collateral types across its chains:
- NFT-backed loans (MultiversX): borrow up to 50% of an eligible NFT's value in EGLD. Eligibility is limited to verified collections, and repayment terms run on fixed interest plans. See how NFT-backed loans work on JewelSwap.
- NFT mortgages (MultiversX): a buy-now-pay-later style path to owning an NFT over time. Read about NFT mortgages on MultiversX.
- Peer-to-pool EGLD lending (MultiversX): supply EGLD to a pool and earn, or borrow EGLD against eligible collateral.
- NFT-collateralized lending (Sui): the same collateral-backed borrowing model extended to the Sui ecosystem.
- NFT AMM and DCA (MultiversX): tools for trading and accumulating NFTs that complement the lending suite.
A worked example: borrowing against a 3 EGLD NFT
Because peer-to-pool loans are collateralized rather than credit-scored, the numbers are concrete and predictable. Suppose you hold an NFT from an eligible, verified collection with a floor price of 3 EGLD:
- JewelSwap lets you borrow up to 50% of that value — so up to 1.5 EGLD against your 3 EGLD NFT.
- Interest is charged through fixed plans. For example, a 16-day plan at 4% costs 0.06 EGLD on a 1.5 EGLD loan (1.5 × 4% = 0.06 EGLD).
- You can repay interest to extend the loan, or repay principal plus interest (1.5 + 0.06 = 1.56 EGLD) to reclaim your NFT.
Your NFT stays locked as collateral throughout, and a Health Factor governs liquidation. A loan can be liquidated if interest goes unpaid or if the Health Factor deteriorates — but liquidation is not instant, giving borrowers room to manage their position. Compare this to marketplace P2P, where a borrower waits for strangers to fund an application and a lender bets on that borrower's credit history. Here, the collateral does the work, and the loan is available the moment the pool has liquidity.
Beyond simple pools: money markets and Flexiloans
JewelSwap extends the peer-to-pool idea into fuller lending infrastructure. Its money markets support both isolated and cross lending, letting users choose between contained, per-asset risk and shared, capital-efficient positions. Pricing is drawn from multiple oracles — Pyth, Umbrella, AshSwap, and xExchange — so collateral and loan values are not dependent on any single feed. Flexiloans apply the same principle to treasuries, turning idle capital into productive, yield-bearing positions.
Peer-to-peer vs peer-to-pool: a quick comparison
- Counterparty: P2P matches one lender to one borrower; peer-to-pool matches everyone to a shared pool.
- Speed: P2P loans wait to be funded; peer-to-pool loans are instant when liquidity exists.
- Risk protection: P2P relies on credit grades; peer-to-pool relies on overcollateralization, a Health Factor, and automated liquidation.
- Custody: P2P platforms hold funds; peer-to-pool protocols like JewelSwap are non-custodial, with funds in smart contracts.
- Transparency: P2P books are internal; peer-to-pool activity is verifiable on-chain.
Neither model is automatically superior for every use case, but for on-chain assets and collateral, the peer-to-pool design removes the frictions that always dogged marketplace lending — the waiting, the manual matching, and the reliance on an operator to hold and account for your money.
Frequently asked questions
Is JewelSwap on Solana?
No. JewelSwap operates on MultiversX, Sui, and Radix only. It does not offer Solana-based products.
What is the difference between peer-to-peer and peer-to-pool lending?
Peer-to-peer lending matches an individual lender to an individual borrower, so loans must be funded before they originate. Peer-to-pool lending has lenders deposit into a shared pool that borrowers draw from instantly against collateral, removing the matching wait and spreading interest across all depositors.
How much can I borrow against my NFT on JewelSwap?
On MultiversX, JewelSwap lets you borrow up to 50% of an eligible NFT's value in EGLD. For example, a 3 EGLD floor-price NFT from a verified collection lets you borrow up to 1.5 EGLD. Interest is charged through fixed plans — a 16-day plan at 4% would cost 0.06 EGLD on that 1.5 EGLD loan.
Do I need a credit score to borrow on JewelSwap?
No. JewelSwap lending is collateral-based. Instead of a credit check, borrowers post collateral — such as NFTs on MultiversX and Sui, or EGLD-eligible assets — and can borrow against it while it stays locked in the protocol, with a Health Factor governing liquidation.
