Choose a Blockchain: Select a blockchain platform like Ethereum or Binance Smart Chain.
Smart Contracts: Build smart contracts using languages like Solidity.
Development Tools: Utilize tools like Truffle or Hardhat for development.
Frontend and Backend Development: Create your app's front and back end.
Deployment: Deploy your smart contract, making your dApp accessible to users.

A crypto exchange API allows developers to integrate exchange functionalities into their dapps. The API provides endpoints for:

Exchange: Execute buy and sell orders.
Market Data: Retrieve real-time market information.
Account Management: Access and manage user accounts and transaction histories.
