What is an Address? An address is a unique string of letters and numbers that identifies where crypto assets, transactions, or smart contracts can be sent or found on a blockchain.
Address Explained A blockchain address is like an account number for crypto.
If someone wants to send you tokens, they need your address so the blockchain knows where to send them.
Addresses can belong to people, wallets, apps, or smart contracts.
Because addresses are long and hard to remember, users often copy and paste them or use readable names like ENS to avoid mistakes.
