In this section, We will explore the features of a DEX, such as Lending, Borrowing, Yield Farming, Staking, Liquidity Pools and the Drawbacks associated with DEXes.
A DeFi lending protocol is a platform where users can lend and borrow crypto assets without intermediaries via P2P. In a traditional financial system, banks give loans to the borrower. A DEX platform allows lenders to earn interest for lending their crypto assets. Additionally, these platforms provide ways for long-term investors to earn high-interest rates.
In DeFi, anyone can become a lender. A lender can loan their assets to others and will be able to generate interests on that loan. This process can be done through lending pools, similar to loan offices in traditional banks. Users can pool their assets and distribute them to borrowers via smart contracts.
Borrowers can choose to borrow from one of these protocols and put down collateral. An important part of these types of loans is that they are over-collateralized. This means borrowers deposit as collateral an amount in crypto more than they borrow. Note that there is a limit to how much funds can be borrowed, this depends on two factors; First is the amount deposited by lenders in the protocol’s funding pool. Second is the quality or “collateral factor” of the coins put down as collateral by the borrower. Borrowers can put down several different coins as deposits each with differing collateral factors. The limit the user can borrow will then be the total sum of these coins amounts multiplied by the collateral factor. It is highly advisable to monitor when to deposit more collateral or maintain a healthy buffer because if the limit is breached, the collateral will be auto-liquidated by the protocol typically at a hefty discount to pay back the loan.
Lending and Borrowing in DeFi explained
Yield farming, also known as liquidity farming, is a means of earning interest on your cryptocurrency, similar to how you’d earn an annual percentage interest when you deposit money with banks. When investors participate in yield farming, their cryptocurrency value grows over time.
Yield farming is made possible through decentralized finance lending platforms that are specific to cryptocurrency. Some of these platforms have algorithms designed to facilitate yield farming. Yield farming works by first allowing an investor to stake their coins by depositing them into a lending protocol through a decentralized app, or dApp.
Users can lend or borrow any cryptocurrency on these platforms, set algorithms to automatically borrow cryptocurrency at low rates and automatically lend cryptocurrency at higher rates.
With RSK smart contract platform, users/investors can benefit from yield farming on Bitcoin. Several decentralized exchange platforms exist which enables users to access defi on Bitcoin, they are;
Sovryn enables Bitcoin holders to yield interest on RBTC, XUSD, FISH, rUSDT, MOC, DOC, BPRO, RIF, MYNT, etc. To get started, visit the Sovryn dApp
RSKSwap is an Automated Liquidity Protocol on RSK. With RSKSwap, you can swap, send and pool tokens like RIF, DOC, BRZ, SOV, rUSDT, rUSDC, RDOC, rDAI, BPRO on the RSK network.
To get started, visit RSKSwap.

Staking is a way of earning rewards for holding certain cryptocurrencies. Cryptocurrencies that allow staking use a “consensus mechanism” called Proof of Stake, which is the way they ensure that all transactions are verified and secured without a bank or payment processor in the middle.
The liquidity pools or LPs are basically pre-funded pools of assets, which serve an important role in the working of AMM-based DEXes. It is a crowdsourced pool of cryptocurrencies or tokens locked in a smart contract that is used to facilitate trades between the assets on a decentralized exchange (DEX). Instead of traditional markets of buyers and sellers, many decentralized finance (DeFi) platforms use automated market makers (AMMs), which allow digital assets to be traded in an automatic and permissionless manner through the use of liquidity pools.
Watch How do Liquidity Pools work?
An operational crypto liquidity pool must be designed in a way that incentivizes crypto liquidity providers to stake their assets in a pool. That’s why most liquidity providers earn trading fees and crypto rewards from the exchanges upon which they pool tokens. When a user supplies a pool with liquidity, the provider is often rewarded with liquidity provider (LP) tokens. LP tokens can be valuable assets in their own right, and can be used throughout the DeFi ecosystem in various capacities.
Usually, a crypto liquidity provider receives LP tokens in proportion to the amount of liquidity they have supplied to the pool. When a pool facilitates a trade, a fractional fee is proportionally distributed amongst the LP token holders. For the liquidity provider to get back the liquidity they contributed (in addition to accrued fees from their portion), their LP tokens must be destroyed.
Liquidity pools maintain fair market values for the tokens they hold thanks to AMM algorithms, which maintain the price of tokens relative to one another within any particular pool.
Impermanent loss happens when the price of a token increases or decreases after you deposit them in a liquidity pool. This change is considered a loss when the dollar value of your token at the time of your withdrawal becomes less than its amount at the time of deposit.
