Decentralized Finance (DeFi) is reshaping how we think about money, lending, and financial systems.
What is DeFi?
DeFi refers to financial applications built on blockchain networks like Ethereum that remove intermediaries.
Key Benefits:
- No banks required
- Transparent transactions
- Global access
- Programmable money
Example Smart Contract (Solidity)
solidity
pragma solidity ^0.8.0;
contract SimpleLending {
mapping(address => uint) public balance;
function deposit() public payable {
balance[msg.sender] += msg.value;
}
function withdraw(uint amount) public {
require(balance[msg.sender] >= amount);
balance[msg.sender] -= amount;
payable(msg.sender).transfer(amount);
}
}S
