To start participating in the DeFi platform and interacting with dApps, you need to connect those dApps to your crypto wallet. In this article, BHO Network will provide you with information and guidance on a crypto wallet that makes it easy for you to use when joining the DeFi platform.

DeFi crypto wallet overview

A crypto wallet is software that allows users to store, manage, and trade their coins/tokens. Besides, with the DeFi platform, the crypto wallet is the key to connecting and interacting with dApps.

Main components of a crypto wallet

Crypto wallets for DeFi usually have 3 main components: Public Key: Is the public key used to send and receive coins/tokens, similar to a bank account Private Key: A private key just like a pin or password to access your bank account. However, the Private Key is different in that it cannot be changed. Seed Phrase: A secret key phrase of 12-24 characters, which is randomly generated when creating a crypto wallet, and is used to restore the wallet in case you change your device or forget your Private Key.

How crypto wallet works

The coins/tokens transaction of a crypto wallet is not the same as sending and receiving money in banking applications. When you made a coins/tokens deposit, you used your Private Key to sign the transaction and broadcast it to the blockchain network. The network will then include your transaction to reflect the updated balance in your address and the recipient's.

The term 'wallet' can be misleading because crypto wallets don't actually store coins/tokens in the same way that physical wallets hold cash. Instead, the crypto wallet will read the public ledger to show the balance in the wallet address, and hold and use the Private Key allowing you to make transactions and interact on dApps.

Therefore, the main activity of a crypto wallet is that you confirm your coins/tokens’ sending/receiving address on the blockchain network through your Private Key. Speed and security often depend on the type of wallet you have.

Why you need a crypto wallet

Your cryptocurrency is only as safe as the method you use to store it. While it is technically possible to store cryptocurrencies directly on an exchange, you should not do so unless in small amounts or if you plan to trade frequently.

For larger amounts, it is recommended to withdraw most of it to a crypto wallet. This way, you retain ownership of your Private Key and have complete control over your own finances.

However, when using a crypto wallet, you need to keep your Private Key and Seed Phrase safe, losing them means losing access to your wallet. Therefore you need to store securely and choose a reliable wallet provider.

How to create a crypto wallet?

Learn about 3S Wallet

To start using a crypto wallet, you can learn and use BHO Network's 3S Wallet.

3S Wallet is a crypto wallet that optimizes user experience through one-touch design on mobile apps. This allows you to do things quickly and conveniently. At the same time, the wallet also has personalization features such as naming the wallet, changing the avatar or storing the frequently used wallet contacts.

Currently, 3S Wallet is available on both iOS and Android devices.

Besides, 3S Wallet is also a multi-chain wallet that supports many networks such as: Ethereum, Binance Smart Chain, Polygon, Fantom, Avalanche, Optimistic, Arbitrum, Cronos, Solana and BHO Chain, etc. Furthermore, 3S Wallet will continue to support even more blockchain networks in the future to bring the greatest convenience to users.

3S Wallet allows you to store more than 3000 coins/tokens and, through the integration of the world's leading payment gateway Moonpay, allows you to buy and sell more than 80 coins/tokens directly with your bank account or fiat currency.

How to create a wallet on 3S Wallet

After downloading and opening the wallet application, there will be 2 options: [Create a new BHO wallet] or [I already have a wallet] on the welcome screen of 3S Wallet. As a newbie, you should select [Create New BHO Wallet].

The system will show the “Completed” message after only 3s of initialization and forward to the main screen of 3S Wallet.
