Family that is The Smart Contracts of Ethereum are digital programs that execute automatically on the Ethereum blockchain when certain conditions are met, without the need for intermediaries.
Simply put 👇
👉 They are smart contracts that fulfill themselves.
What do Smart Contracts do?
Execute agreements automatically
Store rules and conditions
Move money (ETH or tokens)
Cannot be modified once published
How do they work?
1️⃣ The contract is written in a language called Solidity
2️⃣ It is uploaded to the Ethereum blockchain
3️⃣ It is recorded publicly, securely, and immutably
4️⃣ When someone interacts with it, it executes automatically
Simple example
Imagine a betting contract:
“If team A wins the match, the money goes to Juan.
If team B wins, the money goes to María.”
👀 The smart contract:
Receives the money
Verifies the result
Sends the payment automatically
❌ Without a bank
❌ Without a referee
❌ Without intermediaries
What are they used for?
🏦 DeFi (loans, exchanges, staking)
🎨 NFTs
🎮 Blockchain games
🪙 Tokens (ERC-20, ERC-721)
📜 Digital legal agreements
🔐 Advantages
👾Transparency
👾 Security
👾 Trust without intermediaries
👾 Total automation
⚠️ Important to know
Once created, they cannot be changed
If the code has errors, the error remains
Each execution pays gas
Blessings and successes
