A smart contract audit evaluates an intelligent contract for security vulnerabilities and compliance with best practices. A smart contract audit aims to improve your code’s security and reliability, protecting your users and your reputation.
Several steps in conducting an intelligent contract audit include analyzing the code, testing for vulnerabilities, and reviewing for compliance. Internal or external auditors can perform smart contract audits; however, choosing an auditor with experience in Ethereum development and Solidity programming is essential. Audits should be conducted regularly throughout the life of your project to ensure that security vulnerabilities are identified and addressed quickly.

What is DeFi?
DeFi, or decentralized finance, is a catch-all term for financial services built on Ethereum that don’t rely on traditional intermediaries like banks or brokerages. From lending and borrowing platforms to stablecoins and tokenized BTC, the DeFi ecosystem has launched an expansive network of integrated protocols and financial instruments. By deploying Ethereum’s smart contracts, DeFi developers can programmatically route value across decentralized applications (DApps), providing users with a one-stop-shop for all their financial needs.
The breakthrough of defi development is that crypto-assets can now be used in ways not possible with fiat or “real world” assets. Decentralized exchanges, synthetic assets, and flash loans are novel applications that can only exist on blockchains. This paradigm shift in financial infrastructure can upend traditional finance and create a more inclusive economy for everyone.
The DeFi price is growing exponentially, with over $13 billion worth of value locked in Ethereum smart contracts as of August 2020. As the ecosystem matures, we can expect to see an influx of users and an explosion in the development of new DeFi applications. Get ready to join the revolution!
How does DeFi work?
DeFi, or decentralized finance, is a financial system that runs on the Ethereum blockchain. It includes protocols, platforms, and applications that enable users to lend, borrow, and trade without needing a centralized third party.
In other words, DeFi is a way to use Ethereum’s decentralized infrastructure to build financial applications available to anyone with an Internet connection.
This is possible because DeFi app is built on Ethereum’s smart contract platform, allowing developers to create programmable money and financial instruments.
Because DeFi applications are decentralized, they are not subject to the same regulations as traditional financial institutions. This means anyone can use them without going through a bank or other financial institution.
This also makes DeFi applications more accessible to people in countries where traditional financial institutions are not available or are not trustworthy.
DeFi applications can potentially disrupt the way we think about money and finance, and they are already starting to do so.
Defi work in the following way:
There are three main types of DeFi applications: protocols, platforms, and dapps.
- Protocols are the building blocks of the DeFi ecosystem. They provide the basic infrastructure that enables other DeFi applications to function.
- Platforms build on top of protocols to offer additional features and services.
- Dapps are decentralized applications that run on top of defi project platforms. They offer various financial services, from lending and borrowing to trading and investing.
- The DeFi ecosystem is still in its early stages and constantly evolving. New protocols, platforms, and dapps are being created all the time.
What are some of the leading DeFi Protocols?
There are a few different defi cryptocurrency protocols, each with features and functions. Some of the leading protocols in the space include:
MakerDAO: Maker is a decentralized lending platform that allows users to take out loans in Dai, an Ethereum-backed stablecoin. Dai can be used to collateralize loans and traded on decentralized exchanges.
Compound: Compound is a lending platform that allows users to earn interest on their cryptocurrency holdings. Interest rates are set by the protocol and are based on the supply and demand of each asset.
Sushiswap: Sushiswap is a decentralized exchange built on the Ethereum blockchain. It allows users to trade various assets, including ETH, Dai, and other ERC20 tokens.
Uniswap: Uniswap is another decentralized exchange that allows users to trade ETH and ERC20 tokens. It uses a smart contract to facilitate trades and does not require an order book.
These are just a few of the leading protocols in the DeFi space. Each one has its unique features and functions. As the space continues to grow, we can expect to see even more innovative protocols emerge.
How to get started with DeFi
If you want to start with DeFi, you can start using one of the many wallets that support Ethereum and DeFi applications.
MetaMask is a popular option that allows you to quickly access DeFi applications in your browser.
Coinbase Wallet also supports Ethereum and DeFi applications.
To explore more advanced options, you can use a decentralized exchange like 0x Protocol or Kyber Network to trade Ethereum-based assets.
You can also use a lending platform like MakerDAO to earn interest on your ETH.
These are just a few of the many ways you can get started with DeFi. As the ecosystem continues to grow, there will be more and more ways to use DeFi applications.
Finally, tokenized BTC platforms like Wrapped BTC and RenBTC have been gaining traction in recent months. These platforms allow users to wrap their BTC on Ethereum and trade it on DeFi applications.
If you’re interested in getting started with best defi projects 2021, the best way to do it is to start using some of the abovementioned applications.
The best way to stay up-to-date on the latest developments in the DeFi space is to follow one or more of the many excellent available resources.
