A crypto wallet is a tool for storing and transferring cryptocurrencies and interacting with blockchain networks. There are three main types of wallets: software, hardware, and paper wallets. Based on their connection to the internet, wallets can also be classified as hot or cold.
A crypto wallet consists of public and private key pairs, which are used to sign, send, and receive transactions and track asset ownership. The wallet generates a public key from the private key, creating a public address in the form of letters and numbers. This address is used to receive cryptocurrency assets, and it can be shared with others. However, the private key must be kept secret to prevent asset loss.
To use OKB or other tokens on OKB Chain, you need to create a wallet that supports the chain and set up your key management strategy.
Here are some simple steps to integrate a client-side application with OKB Chain:
Set up Web3: web3.js is a useful Javascript library that enables a client-side application to communicate with the blockchain. To establish this communication, we configure web3.js to use a developer-based wallet such as MetaMask. You can consult the web3.js docs to learn how to add web3.js to your project.
Set up an Account: Once web3 is successfully installed, you can begin to send transactions that change the state of blockchain.
Instantiate Contracts: Once a web3 object is in place, we next instantiate our deployed contract, with which we interact.
Call functions: To fetch data from the contract, you can use functions available in the contract object.
