Learn how crypto-backed loans work: LTV, liquidation, and Health Factor. Borrow against your crypto and NFTs on JewelSwap without selling and keep your upside.

Crypto-backed loans let you unlock cash or on-chain liquidity from your holdings without hitting the sell button. Instead of parting with tokens or NFTs you believe in, you pledge them as collateral and borrow against them — keeping your exposure to future upside while getting spendable capital today. This guide explains how borrowing against crypto actually works, the mechanics you need to understand (LTV, liquidation, Health Factor), the trade-offs between CeFi and DeFi, the real risks, and how JewelSwap approaches crypto collateral loans across MultiversX, Sui, and Radix.
A crypto-backed loan is a loan secured by digital assets. You lock up collateral — tokens, stablecoins, or even NFTs — and in return you receive a loan in another asset. As long as you repay the loan (plus interest) and your collateral keeps its value, you get your collateral back untouched. Nothing is sold. Your position stays intact.
This is fundamentally different from selling. When you sell, you exit your position permanently and, in many jurisdictions, you trigger a taxable event. When you borrow against crypto, you keep ownership and simply access liquidity that would otherwise be locked in an asset you don't want to give up.
Because crypto is volatile, virtually every crypto loan is overcollateralized. That means the value of the collateral you pledge is worth more than the amount you borrow. If you want to borrow $1,000 worth of an asset, you might need to lock $2,000 or more in collateral. This buffer protects the lender (and the protocol) against price swings — if your collateral drops in value, there's still enough backing the loan.
Overcollateralization is also why crypto lending can be permissionless and require no credit checks. The collateral itself is the guarantee. Your credit score, income, and identity are irrelevant — the smart contract only cares about whether your collateral covers your debt.
Loan-to-Value (LTV) is the single most important number in any crypto collateral loan. It expresses your loan amount as a percentage of your collateral's value:
LTV = (loan amount / collateral value) × 100
Example: You own an NFT with a floor value of 3 EGLD. You borrow the maximum allowed — 50% LTV — which is 1.5 EGLD. Your LTV is 50%. If your collateral's value rises, your effective LTV falls, giving you more breathing room. If it drops, your LTV climbs toward the danger zone.
Lower LTV means a safer loan with more cushion before trouble. Higher LTV means more capital extracted per dollar of collateral, but far less room for error if prices move against you. Protocols cap the maximum LTV precisely to keep loans safely overcollateralized.
If your collateral falls enough that your loan is no longer safely covered, your position becomes eligible for liquidation — the collateral is sold or claimed to repay the debt. This is the mechanism that keeps the whole system solvent.
Many modern protocols express liquidation risk through a Health Factor: a running score that reflects how safe your position is relative to its liquidation threshold. When the Health Factor is comfortably high, you're fine. As it approaches the threshold, you're at risk. Crucially, a good Health Factor system does not liquidate instantly on a momentary wick — it governs liquidation as a graded condition, giving borrowers a clearer picture of their standing than a single hard cutoff.
You can improve your Health Factor at any time by repaying part of the loan or adding more collateral. Managing it actively is the key discipline of borrowing against crypto responsibly.
There are two broad ways to get a crypto-backed loan, and the difference matters enormously for your risk.
With a CeFi lender, you hand your collateral to a company that custodies it and issues you a loan. The experience can feel familiar and simple, but it introduces counterparty risk: you're trusting a business to safeguard your assets, stay solvent, and return them. The last cycle showed how badly that can go when centralized lenders froze withdrawals or collapsed, taking user funds with them. In CeFi, "your keys" become their keys.
In DeFi, the loan is executed by transparent smart contracts. Collateral is locked in code, not held by a company. Rules — LTV caps, interest rates, liquidation logic — are enforced automatically and are auditable on-chain. The standout benefit is self-custody: you interact directly from your own wallet, and there's no company that can freeze your account or lose your deposit to its own bad bets. The trade-off is that you take on responsibility for managing your position and understanding the protocol.

The practical takeaway: borrow conservatively, keep your LTV well below the cap, watch your Health Factor, and keep a repayment or top-up plan ready.
JewelSwap is a non-custodial, multi-chain DeFi protocol operating on MultiversX, Sui, and Radix. Everything is self-custody — you borrow directly from your own wallet, and no company ever takes custody of your assets. Here's how the pieces fit together.
JewelSwap lets you borrow against your NFTs on MultiversX. You can borrow up to 50% of a verified NFT's value in EGLD — a conservative, safely overcollateralized cap. The worked example makes it concrete:
You own an NFT with a 3 EGLD floor value. You can borrow up to 1.5 EGLD against it (50% LTV). On a 16-day plan at 4%, your interest comes to 0.06 EGLD. Repay the loan plus that interest and your NFT is returned to your wallet — you never sold it, and you kept any upside in the meantime.
Liquidation is governed by a Health Factor rather than an instant hair-trigger, so a temporary dip doesn't automatically cost you your NFT. You keep visibility into where your position stands and can act before it becomes critical.
For token-based borrowing, JewelSwap runs money markets offering both isolated and cross lending. Isolated markets ring-fence risk to a single asset pair; cross lending lets you borrow against a broader basket of collateral. Collateral and debt are priced by a combination of Pyth, Umbrella, AshSwap, and xExchange oracles, reducing reliance on any single price source. For organizations, Flexiloans provide flexible borrowing designed for treasuries.
Across every product, the constant is the same: JewelSwap is fully non-custodial. You retain control of your assets, borrowing is enforced by transparent smart contracts, and you decide how conservatively to manage your LTV and Health Factor.
No. JewelSwap operates on MultiversX, Sui, and Radix only. It does not offer Solana-based products.
No — that's the entire point of a crypto-backed loan. You pledge your asset as collateral, borrow against it, and get it back when you repay. You keep ownership and any future upside, and you avoid triggering a sale.
Up to 50% of a verified NFT's value in EGLD on MultiversX. For example, a 3 EGLD floor NFT can borrow up to 1.5 EGLD. On a 16-day plan at 4%, the interest would be 0.06 EGLD.
Your LTV rises and your Health Factor falls. If it deteriorates past the threshold, your position becomes eligible for liquidation. Because liquidation is governed by a Health Factor rather than an instant cutoff, you can reduce risk by repaying part of the loan or adding collateral before it becomes critical.
