How to Create Decentralized Finance (DeFi) Wallet?
DeFi has become a popular alternative to traditional banks, brokers, exchanges and other financial institutions in a flash. Thus, in 2020, the value of assets locked in DeFi-protocols increased by 2000%, reaching $ 13 billion (the market grew to $ 55 billion in the first half of 2021). At the same time, DeFi wallets have become the main beneficiaries of the industry's growth, since it is they who connect users and decentralized financial services, taking a small commission for their intermediation on most transactions.
This article will show you how to run your DeFi wallet. We'll look at the specifics of this market and then outline the main development steps and factors to pay attention to when launching a DeFi product.
Decentralized finance, or DeFi, is a collective term for all financial applications and protocols that are controlled not by centralized nodes but by decentralized algorithms / or multiple independent individuals or institutions. At the same time, the main focus in DeFi projects is to ensure that each user is in control of their finances, excluding intermediaries.
For example, in the traditional financial system, users can put their money on a deposit in a bank at 1% per annum (in dollars), after which the bank uses this money to issue loans at 10% per annum. Whereas in DeFi, the user can issue loans himself using smart contracts, receiving the same 10% per year. At the same time, unlike banks, DeFi projects can issue loans to everyone who has access to the Internet, not just individuals and legal entities in their city or country.
In addition to lending, DeFi also offers services in insurance (Nexus Mutual), investments (PieDAO BTC ++), deposits (Celsius Network and Bitwala), liquidity pools (Kyber, Uniswap, Bancor), bonus points (Fold, Loli, Pei and Donut).
You are in control of your money. Instead of giving your money into the hands of banks, companies or the state, you store and control it in crypto accounts. So you will not lose your funds if a bank or country becomes bankers or victims of hackers, fraudsters and corrupt officials.
Faster than traditional finance. Making a deposit or a loan in traditional banks takes several days, if not more. Whereas in DeFi it takes a few seconds or minutes, depending on the blockchain.
Maximum transparency. All DeFi projects are created on the basis of open source code, so everyone can check them and make sure they are honest and safe. How banking and government systems work, none of the ordinary users knows.
High confidentiality. DeFi smart contracts and apps are pseudo-anonymous and only contain public addresses. There’s no need to connect personal identity with a DeFi project.
Economic efficiency. DeFi app users can earn passive income from crypto assets (deposits, loans, insurance) and save on fees for transfers, loans, deposits and insurance.
Automation. Smart contracts allow you to automate most business processes in the field of decentralized finance, which reduces their execution time, cost and dependence on third parties.
Independence. Users have 100% control over their assets. DeFi doesn't need centralized intermediaries and regulators.
Safety. The information recorded on the blockchain cannot be changed. Therefore, no one can falsify your data. Also, the lack of a single point of failure makes the entire system less vulnerable.
Availability. Anyone can connect a crypto wallet to the DeFi blockchain network and start using it, regardless of geographic or regulatory factors.
All DeFi wallets are based on the “be your own bank” concept. These are blockchain applications through which end users store their tokens and interact directly with DeFi projects. They offer freedom and accessibility, security, transparency and confidentiality, ensuring that the user is 100% responsible for managing their own funds.
The main task of the DeFi wallet is to allow end users to administer their funds with complete freedom, to do whatever they want. The only person in charge of his money is himself, which is quite a revolutionary concept when you consider that in the world of traditional finance money is, in fact, controlled by banks and regulators.
In addition, unlike centralized wallets, DeFi wallet users do not need to verify their identity or provide any background information. This applies to both the storage and management of funds, and participation in DeFi projects: they will interact with the wallet (account) without disclosing personal data, all that they will know is the public address.
We have already written above that DeFi wallets are considered one of the safest, since they are created on the basis of the blockchain, open source code and, at the same time, in fact, do not have access to the money of their end users. However, along with the advantages, DeFi wallets also have disadvantages. Since this market is based on anonymity and lacks a regulatory framework, DeFi users can be an easy target for scammers, hackers. Weak architecture of smart contracts, errors in the code, insecure integration can also make the system vulnerable.
To avoid the abovementioned problems, you should do the following things when developing your own DeFi wallet:
MetaMask. It is a cryptocurrency wallet that acts as a bridge to access Ethereum dApps. It supports tokens that meet the ERC-20 and ERC-721 standards, except for ETH (Ethereum's own currency). Most users log into MetaMask via browser extensions (Brave, Chrome, Microsoft Edge and Firefox), but it also has a very handy mobile app.
When creating an analogue of MetaMask, you need to pay close attention to security, since this service is mainly used through a web interface, which poses great security risks. In addition, it will be necessary to implement integration with Instadapp and Compound finance, as well as compatibility with ENS (allows you to attach a readable domain to the crypto address).
Coinbase. It is one of the friendliest wallets that will make it easy to transfer funds, buy and store tokens, and interact with other decentralized applications. Moreover, interaction with some DeFi services, such as Compound and dYdX (lending), is built into the interface of the Coinbase wallet, which makes it easier to work with them and reduces security risks.
Argent. A mobile wallet for iOS and Android that targets users new to decentralized finance and blockchain. It allows you to access DeFi protocols Aave, Compound, Social TokenSets and Kyber. When creating an Argent clone, your DeFi wallet development service should focus on pleasant appearance and ease of use. In addition, you will also need to create your own analogue of Argent Guardians.
The development of DeFi solutions differs from the creation of conventional software, as such services are not managed by any financial institution or central regulators. Execution of all service logic is provided by blockchain and smart contracts. Their development and / or customization requires appropriate knowledge and experience. So if you need to create a cryptocurrency wallet, then this task is best entrusted to a development company that specializes in such projects, such as Merehead.
