Loans primarily based on cryptocurrencies have develop into a mainstay of the decentralized finance (DeFi) universe ever for the reason that good contract-based lending/borrowing platforms started providing the service to crypto customers. The Ethereum community, the primary blockchain that scaled the good contract performance, sees many of the complete worth locked (TVL) on DeFi protocols dominated by cryptocurrency lending platforms.
In keeping with knowledge from DeFi Pulse, the highest 4 of 10 DeFi protocols are lending protocols that account for $37.04 billion in TVL, simply 49% of TVL of the complete DeFi market on the Ethereum blockchain. Ethereum leads by way of being essentially the most utilized blockchain for the DeFi market and the TVL on the community. Maker and Aave are the largest gamers right here, with a TVL of $14.52 billion and $11.19 billion, respectively.
Even on different blockchain networks like Terra, Avalanche, Solana and BNB Chain, the adoption of cryptocurrency-based loans has been one of many predominant use instances of good contracts on this planet of DeFi. There are about 138 protocols that present crypto loan-based providers to customers, amounting to a complete TVL of $50.66 billion, according to DefiLlama. Aside from Aave and Maker, the opposite outstanding gamers on this protocol class throughout blockchain networks are Compound, Anchor Protocol, Venus, JustLend, BENQI and Solend.
Johnny Lyu, the CEO of crypto trade KuCoin, talked to Cointelegraph in regards to the selection of blockchain networks for crypto lending. He stated:
“I might say the perfect blockchain for loans and DeFi doesn’t exist, as every has its personal benefits. On the similar time, the management of Ethereum is simple on account of many components.”
Nonetheless, he didn’t negate the opportunity of the emergence of a very best blockchain for DeFi. Kiril Nikolov, DeFi strategist at Nexo — a cryptocurrency lending platform — seconded this view. He informed Cointelegraph:
“The quick reply is ‘no.’ Most blockchains are crypto lending-friendly. Nonetheless, among the many main properties to observe for are liquidity and reliability, whereas a secondary figuring out issue is perhaps community charges.”
Contemplating that the liquidity and reliability of the Ethereum platform are the best proper now on account of it being essentially the most utilized blockchain inside DeFi, one may take into account profiting from the identical and making it the blockchain of selection.
Outstanding gamers
To start out with, a borrower wants to decide on between the key lending protocols on the community corresponding to Maker, Aave and Compound. Whereas there are a plethora of crypto lending platforms, on this piece, essentially the most outstanding ones are thought-about for the sake of ease of explaining and relatability.
Cryptocurrency lending basically permits customers to borrow and lend digital belongings in return for a price or an curiosity. Debtors have to deposit collateral that may immediately permit them to take a mortgage and use it for the aims of their portfolio. You may take loans with none collateral, referred to as flash loans, on platforms like Aave. These loans have to be paid again throughout the similar block transaction and are primarily a function meant for builders as a result of technical experience required to execute them. Moreover, if the loaned quantity will not be returned plus the curiosity, the transaction is canceled even earlier than it’s validated.
Since crypto-based loans are fully automated and easy for the common retail investor and market members, on the whole, they supply a simple method to earn annual share yields on the digital belongings they’re hodling and even accessing low-cost credit score traces.
One vital side of collateralized loans is the mortgage to worth (LTV) ratio. LTV ratio is the measurement of the mortgage stability in relation to the worth of the collateral asset. Since cryptocurrencies are thought-about to be extremely risky belongings, the ratio is normally on the decrease finish of the spectrum. Contemplating Aave’s present LTV for Maker (MKR) is 50%, it basically means which you can borrow solely 50% of the worth as a mortgage in relation to the collateral deposited.
This idea exists to offer shifting room for the worth of your collateral in case it decreases. This leads to a margin name the place the person is requested to replenish the collateral. When you fail to take action and the worth of the collateral falls under the worth of your mortgage or one other predefined worth, your funds will likely be offered or transferred to the lender.

The extent of the impression of cryptocurrency-based loans reaches out of the DeFi market because it permits entry to capital for people or entities with no credit score verify. This brings a mass inhabitants of individuals the world over which have a weak credit historical past or no credit score historical past in any respect. Since lending and borrowing are all pushed by good contracts, there is no such thing as a actual age restrict for the youthful era to become involved, which is historically not potential by a financial institution as a result of lack of credit score historical past.

Issues and dangers
Because the adoption of DeFi-based loans has now risen to such an extent that even international locations like Nigeria are taking advantage of this service and El Salvador is exploring low-interest crypto loans, there are a number of concerns and dangers which can be noteworthy for buyers seeking to dabble on this area.
The first danger concerned with crypto lending is wise contract danger since there’s a good contract in play managing the capital and collateral inside every DeFi protocol. A method this danger could be mitigated is by sturdy testing processes applied by the DeFi protocols deploying these belongings.
The following danger it is advisable take into account is the liquidity/liquidation danger. The liquidity threshold is a key issue right here as a result of it’s outlined as the share at which a mortgage is taken into account to be under-collateralized and thus results in a margin name. The distinction between LTV and liquidity threshold is the protection cushion for debtors on these platforms.
For lenders, there’s one other extra danger associated to impermanent loss. This danger is inherent to the automated market maker (AMM) protocol. That is the loss that you just incur once you present liquidity to a lending pool, and the underlying value of the deposited belongings falls under the worth at which they had been deposited into the pool. Nonetheless, this solely happens when the charges earned from the pool don’t compensate for this drop in value.

Nikolov identified one other danger with DeFi lending platforms. He stated that “One other one is dangerous collateral itemizing which may result in disturbances of the complete platform. So, if you happen to’re not keen to take these dangers, we suggest borrowing from a platform like ours that ensures you sure protections corresponding to insured custody and over-collateralization.”
There have been a number of situations of hacks for the reason that growing reputation of DeFi together with Cream Finance, Badger DAO, Compound, EasyFi, Agave and Hundred Finance.
Moreover, cryptocurrency lending and borrowing platforms and customers each are topic to regulatory danger. Lyu talked about that the regulatory framework on this difficulty has not been totally shaped in any main jurisdiction, and the whole lot is altering proper earlier than our eyes. It’s essential to separate debtors from one another — personal debtors and firms of debtors.
Primarily, the dangers highlighted makes it important so that you can train excessive warning when deploying your capital in crypto-based loans, both as a borrower or as a lender. Paolo Ardonio, the chief expertise officer of crypto trade Bitfinex, informed Cointelegraph:
“It is crucial that these taking part in crypto lending on DeFi platforms be aware of the dangers in what continues to be a nascent area within the digital token financial system. We’ve seen quite a few high-profile safety breaches which have put the funds of each debtors and lenders in danger. Except funds are secured in chilly storage, there’ll inevitably be vulnerabilities for hackers to use.”

Way forward for DeFi lending
Regardless of the dangers talked about, cryptocurrency-based lending is among the most developed areas in DeFi markets and continues to be witnessing fixed innovation and development in expertise. It’s evident that the adoption of this DeFi class is the best among the many quite a few others rising within the blockchain business. The usage of decentralized id protocols might be built-in into these platforms for the verification of customers to keep away from the entry of scrupulous gamers.
Ardonio spoke additional on the innovation anticipated in DeFi loans this yr, stating, “I count on to see extra innovation in crypto lending, notably by way of the usage of digital tokens and belongings as collateral in loans. We’re even seeing nonfungible tokens getting used as collateral in loans. This will likely be an rising pattern this yr.”
