Decentralized Lending: A Complete Guide to DeFi

Os decentralized lending are a financial innovation that allows you to request and grant loans without traditional intermediaries, such as banks or centralized entities. Using technology blockchain and smart contracts (smart contracts), this system democratizes access to capital, offers total transparency and operates 24 hours a day. Next, we explore how they work, their benefits, risks, and their impact on the financial world.

What are decentralized loans?

Los decentralized lending they are part of the ecosystem DeFi (Decentralized Finance). Unlike traditional loans, where a bank evaluates your credit history and approves or rejects your request, everything here is managed through automated protocols in the blockchain.

Key Features:

• Without intermediaries: There are no banks or institutions that control the process.
• Guarantee in cryptoassets: To get a loan, you usually have to deposit a collateral (for example, Bitcoin or Ethereum) that supports the requested amount.
• Automatic execution: Los smart contracts manage loans, interest and liquidations without human intervention.

How do they work?

1. Security depositThe user blocks cryptocurrency in a liquidity pool as a guarantee. For example, if you deposit $1,000 in ETH, you could borrow up to a certain percentage (for example, $700) in Stablecoins such as DAI or USDC.
2. Request for the loanEl Smart contract automatically calculates the maximum amount you can ask for, based on the value of your guarantee and the collateralization ratio (generally between 120% and 150% or more).
3. Interest paymentInterest rates are dynamically adjusted, often in real time, depending on supply and demand within the liquidity pool. Lenders receive interest for providing liquidity, while borrowers pay to use the funds.
4. Automatic liquidationIf the value of the security falls below a minimum ratio established by the protocol (for example, if the value of your deposited ETH falls dangerously close to the value of the loan), the Smart contract can automatically liquidate the collateral to cover the loan and maintain the solvency of the system.

Key Differences vs. Traditional Loans

‍

Benefits of Decentralized Lending

1. Financial Inclusion Anyone with access to the internet and cryptoassets can participate, often without the need for a traditional credit history or extensive documentation. This is especially valuable in regions with limited or poorly accessible banking systems.
   ‍
2. Speed and efficiency Loans can be obtained and managed much faster, often in a matter of minutes, thanks to automation through smart contracts that eliminate bureaucratic processes.
   ‍
3. Control and custody In many DeFi protocols, users can maintain greater control over their funds by interacting directly from their own cryptocurrency wallets, although collateralized assets are blocked by the Smart Contract.
   ‍
4. Performance opportunities for lenders Those who provide liquidity to loan pools (lenders) can obtain potentially attractive returns on their digital assets, which are usually variable and depend on the demand for loans on the platform.

Risks and Challenges

1. Collateral volatilityThe value of cryptocurrencies used as collateral can be very volatile. If the value of your collateral drops sharply, you may face a automatic liquidation, losing part or all of your warranty. For example, if the ETH deposited as collateral loses 30% of its value quickly, the protocol could sell it to secure the repayment of the loan.
   ‍
2. Technical and smart contract vulnerabilitiesLos smart contracts, despite their automation, are not infallible. Errors in the code (Bugs) or exploits can lead to significant loss of funds. Cases such as the collapse of the Yam Finance protocol in 2020 due to a bug highlight this risk.
   ‍
3. Uncertain regulationThe regulatory framework for decentralized finance (DeFi) is still under development in many countries. This creates uncertainty and the possibility of abrupt regulatory changes that could affect users and platforms.
   ‍
4. Overcollateralization Most of the decentralized lending require overcollateralization, which means that you must deposit a security whose value is significantly greater than the amount of the loan you receive (for example, deposit $150 in ETH to obtain a $100 loan in DAI). While this protects lenders, it limits access to credit for those who do not have substantial initial capital.

Popular DeFi lending platforms

1. Renovate: Reenlever is a decentralized P2P lending platform that offers immediate liquidity to investors with real estate tokens of Reental. Instead of selling your tokens and losing long-term benefits, you can use them as collateral to obtain funding and continue to generate returns.
   ‍
2. Aave One of the leading platforms that allows loans and deposits with a wide variety of cryptocurrencies. It is known for innovations such as “Flash Loans” (collateral-free loans that must be taken and returned within the same blockchain transaction).
   ‍
3. Compound A protocol where interest rates are calculated algorithmically per block (for example, every approximately 15 seconds on Ethereum). Users earn COMP tokens (the platform's governance token) for interacting with the protocol, both lending and borrowing.
   ‍
4. MakerDAO It is the project behind DAI, one of the decentralized stablecoins most important, which is backed by a basket of collateral. Through platforms such as Spark Protocol, MakerDAO offers DAI lending solutions.
   ‍
5. Curve FinanceAlthough it is primarily a decentralized exchange, it specializes in the efficient exchange between Stablecoins (such as USDT, USDC, DAI), which indirectly facilitates certain types of lending strategies and Yield Farming by minimizing slippage and the risk of volatility between these assets.

Real use cases

1. Investors looking for liquidity without selling their crypto assets If you own Bitcoin or Ethereum and you think their value will increase in the long term, you can use these assets as collateral to obtain a loan in Stablecoins and thus have immediate liquidity without the need to sell your cryptocurrencies.
   ‍
2. Yield agriculture (Yield Farming)Some users borrow cryptocurrencies (usually stablecoins with relatively low interest rates) and then invest them in other DeFi protocols that offer higher returns, although this strategy involves additional risks.
   ‍
3. Access to capital in struggling economies In countries with high inflation or restricted access to traditional financial services, decentralized lending within Stablecoins (linked to strong currencies such as the US dollar) may offer a more stable and accessible alternative for raising capital.
   ‍
4. Reinvestment in Reental: Reental investors collateralize their real estate tokens by obtaining a loan with which they can reinvest in other real estate projects, thus increasing their initial return without the need for a new outlay,

The Future of Decentralized Lending

1. Real-World Asset Tokenization (RWA) A growing trend is the use of Tokenized real-world assets as collateral in DeFi. Platforms such as Reental is innovating in this space, allowing users to use their Reental tokens (which represent shares in real estate assets) as security to obtain decentralized lending. This merges traditional finance with DeFi, expanding the possibilities of collateralization and access to credit.
   ‍
2. Improvements in capital efficiency and risk managementMore sophisticated models for risk assessment, dynamic collateralization ratios and loan options with lower collateralization (or even without it for certain verified use cases) are expected to be developed as technology and decentralized identity systems evolve.
   ‍
3. Increased institutional adoption As regulatory clarity improves and technology matures, more traditional financial institutions are likely to begin to explore and integrate solutions for decentralized lending in their offers.

Los decentralized lending are redefining the credit landscape, offering a more open, efficient and transparent system. While risks are significant and must be managed carefully, their potential to transform access to capital globally is undeniable.
