6 Risks of DeFi Loans - Know Before you Borrow in 2026

DeFi, short for decentralised finance, is a way of borrowing, lending, and trading crypto using software instead of banks or companies. It was built to remove middlemen, but it also removes many of the safety rails that exist in normal lending.

In 2026, DeFi is bigger, faster, and riskier than ever. You may have heard of Aave, Compound, Maker, and Morpho via Coinbase. The apps are slick and the rates are cheap, but liquidations can happen in seconds. When something goes wrong, recovery options can be limited. Support may be minimal, legal recourse may be unclear, and outcomes often depend on protocol rules, governance decisions, or third-party interfaces.

This guide explains the real risks of DeFi, why many bitcoin holders underestimate them, and how bitcoin backed lending with Ledn avoids these risks.

DeFi looks cheap, but isn’t

At first glance, DeFi loans often look cheaper than other loans. You might see rates of 6%, 7%, or even lower. But the interest rate is only one part of the real cost of borrowing.

What many people don’t factor in is the risk that something fails at the wrong time. That could be a sudden liquidation, a pricing error, or an issue with how the asset is being represented on chain.

DeFi apps are designed to feel simple and familiar. A loan position that can change very quickly is often displayed with the same clean layout as a savings account, even though the risks are very different. There’s usually no legal agreement and no formal recovery process if something goes wrong.

With a bank or a regulated lender, there’s a company, a contract, and a legal framework behind the loan. With DeFi, the rules are enforced by software, and outcomes depend on how that code behaves under stress.

The main DeFi risks you should know

These are structural risks, built into how DeFi works:

• Bridge risk
• Wrapping and tax risk
• Oracle manipulation
• Protocol exploits
• Liquidation penalties
• No legal protection

All of these have already caused large, permanent losses in real markets.

1. Bridge risk

Bitcoin was not originally designed to work inside most DeFi apps. To use it there, you usually have to convert it into a copy of bitcoin that lives on another blockchain. This is called bridging and wrapping.

When you do this, you’re no longer using real, native bitcoin. Instead, you’re using a token that represents bitcoin, and that token depends on another system or company to actually hold the real bitcoin for you.  

If that bridge or system fails, is hacked, or shuts down, your “bitcoin token” may no longer be backed by real bitcoin at all.

Bridges have already been one of the biggest sources of crypto losses. Major failures include:

• Ronin
• Wormhole
• Harmony

Each of these incidents resulted in hundreds of millions of dollars being lost, and in most cases, users were not fully reimbursed.

Once your bitcoin is bridged, your assets depend on a system you can’t control or fully verify. If that bridge breaks, the original bitcoin behind your token may be gone, and there’s usually no recovery process.

2. Wrapping bitcoin can trigger taxes

Many people think borrowing in DeFi is tax free. In many countries, that’s wrong.

In some countries, wrapping bitcoin can be treated as selling it. That can trigger capital gains tax before you even borrow a single dollar.

1. You wrap bitcoin
2. You trigger a taxable event
3. You borrow
4. You still face liquidation risk

With a bitcoin backed loan from a regulated lender like Ledn, your bitcoin stays native. There’s no wrapping and no disposal. In most cases, that means no tax is triggered by the loan (but please be aware that tax implications of using Ledn products vary depending on your individual situation, the country or region where you reside, and how transactions are classified under the local tax laws.)

3. Oracle manipulation 

DeFi loans rely on price oracles to decide when positions should be liquidated. An oracle is a data feed that tells a protocol what your collateral is worth. If that price is inaccurate or can be influenced, the feed can make the wrong decision.

This has already happened in several well known cases, including:

• Mango Markets
• Thorchain
• Balancer

In the Mango Markets case, for example, traders were able to affect the price used by the protocol and borrow against overstated collateral values, leading to losses of over $110M.  

As liquidity becomes more spread out across chains and pools, it gets easier to influence pricing in smaller markets. When this happens, the protocol simply follows its rules and triggers liquidations based on the data it receives.

4. Protocol exploits 

DeFi platforms depend on smart contract code to function. Like any software, this code can contain weaknesses that can be exploited.

When an exploit occurs, transactions are processed automatically according to the contract’s logic. There’s typically no manual review process or direct customer support intervention, and outcomes depend on how the protocol is designed and governed.

In practice, this means users rely on the quality of the code, the security audits behind it, and the response of the protocol’s community if an issue arises.

5. Liquidation penalties 

DeFi liquidations are designed primarily to protect liquidity providers. When your loan moves past its liquidation threshold, liquidators can buy your collateral at a discount. The protocol also applies a liquidation penalty, which is often between 5% and 14%.

As a result, borrowers can lose more collateral than what’s strictly required to bring the loan back to a safe level, especially during fast market moves.

Ledn handles this differently. If bitcoin’s price falls and your loan’s LTV rises, you’ll receive alerts giving you time to add collateral or repay part of the loan. If no action is taken and the LTV reaches the liquidation level, only the amount of bitcoin needed to restore a healthy loan is sold, and the rest is returned to you.

6. No legal protection

When you borrow through DeFi platforms, there’s often no legal contract between you and a company. You’re interacting with nothing but software.

That means there’s no clear legal responsibility if something goes wrong. If funds are lost due to a bug, exploit, or design flaw, there’s no standard recovery process and no organisation that is legally required to make things right.

In traditional and regulated lending, borrowers and lenders are bound by legal agreements. If there’s a dispute or failure, there are established legal paths for review, enforcement, and recovery.

With DeFi, outcomes depend largely on code, governance votes, or community decisions, rather than on formal legal protections.

Regulated vs unregulated lending: why it matters in 2026

Some users prefer DeFi for reasons such as self-custody, composability, or permissionless access. The trade-off is that those benefits can come with additional technical, liquidity, governance, and legal complexity.

Unlike unregulated DeFi lenders, regulated lenders work within a defined framework that includes:

• KYC and AML requirements
• Legal loan agreements
• Custody and capital standards
• Regular audits

If something goes wrong, there’s a clear legal process because they operate within a clearer legal and compliance framework. This can provide more defined processes for disputes, disclosures, and asset handling.

DeFi platforms don’t operate within this framework. If a protocol has an issue, the response typically depends on governance votes or community decisions, which can take time. In many cases, losses cannot be recovered.

How Ledn avoids these DeFi risks

Ledn is a centralised (CeFi), regulated lender, which means it doesn’t rely on the high-risk mechanisms that make DeFi borrowing unstable. 

• There’s no wrapping.
• There’s no bridging.
• There are no platform tokens.
• There are no smart-contract liquidations.
• There’s no on-chain DeFi oracle dependency for loan execution.
• There are no governance votes deciding what happens to your collateral.

Your loan is governed by a legal contract and your loan-to-value is monitored in real time. If the market moves, you get clear alerts.  

With Ledn:

• Your bitcoin is held in third-party custody with Ledn or our institutional lending partners
• You can verify that your collateral is fully accounted for through independent Proof of Reserves
• Platform security follows SOC 2 Type 2 standards
• Loans start at conservative LTVs to give you more room during market moves
• You can speak to a real person if you ever need support

Most importantly, Ledn has protected clients’ bitcoin through multiple full market cycles, including major downturns where many other platforms failed.

Get the funds you need, keep your bitcoin

Understand the risk before you choose the loan

If you only need a very short-term loan and fully understand how these platforms work, DeFi can be useful. But for anyone using bitcoin as longer-term collateral, structure matters just as much as the headline APR.

If you want legal protection, predictable liquidation, and real customer support, a regulated bitcoin backed lending model is a better choice. That’s exactly what Ledn was built to provide.

Borrow against your bitcoin without wrapping, bridging, or protocol risk.
