Address
In short: A crypto address is an alphanumeric string that identifies where cryptocurrencies are sent and received on a blockchain.
A crypto address is an alphanumeric string that identifies where cryptocurrencies are sent and received on a blockchain. It works like an account number that can be shared openly, because it is usually derived from a public key and does not reveal the private key that controls the funds.
Why it matters
Every deposit and withdrawal starts with an address, and each network uses its own format: Bitcoin addresses often begin with “bc1”, “1” or “3”, while Ethereum-style addresses start with “0x”. Sending funds to the wrong address or over the wrong network can make them unrecoverable, because confirmed blockchain transactions cannot be reversed. Some networks, such as XRP, also need a destination tag or memo so that a shared exchange address can tell customers apart. Malware that swaps a copied address for an attacker’s is a known risk, which is why careful users compare the characters before sending.
Example
On an exchange such as EX5, the deposit page shows an address for the coin and network you select. You paste it into your wallet’s send screen, check the first and last few characters, and confirm the transfer. Once the transaction is confirmed on the blockchain, the funds arrive at that address and the exchange credits your account. Many users send a small test amount first when they use an address for the first time.
