Wallet Address

A wallet address is the string of letters and numbers used to receive cryptocurrency, roughly comparable to an account number. It is derived from a public key, which in turn comes from your private key, so sharing an address is safe: it shows where funds can be sent, not how to spend them. Addresses are network-specific — a Bitcoin address cannot receive Ethereum tokens, and sending to the wrong network or an unsupported chain usually means permanent loss, because blockchain transactions cannot be reversed. Most address formats include a checksum so that typos are rejected rather than silently accepted, but you should still verify the full string, and be aware that clipboard-hijacking malware can swap a pasted address for the attacker's.
