Wallet address
A wallet address is the public identifier used to receive cryptocurrency on a specific blockchain — derived cryptographically from the public key, safe to share, and distinct per chain (0x… for Ethereum, 1/3/bc1… for Bitcoin, T… for TRON, etc.).
A wallet address is the "receive here" identifier for a blockchain account. It is derived deterministically from the wallet's public key through a chain-specific encoding — Bitcoin uses base58 or bech32, Ethereum uses hex with checksums, Solana and Monero use base58 with different alphabets, TRON uses base58 starting with "T". The address is safe to share; anything sent to it credits the wallet holding the matching private key.
Address formats are chain-specific. A Bitcoin address ("bc1..." or starting with 1/3) is not a valid Ethereum address, and vice versa. EVM chains (Ethereum, BSC, Polygon, Arbitrum, etc.) all use the same 0x + 40 hex format, which means the same address string can represent balances on multiple chains — which chain the balance actually lands on depends on the transaction, not the address. Sending on the wrong network is a common way to lose funds.
Address reuse (using the same address for many payments) is fine for functionality but weakens privacy: an observer can cluster every payment to that address as going to the same recipient. Privacy-conscious wallets generate a new address per payment. Monero handles this automatically via stealth addresses.
