definition

A cryptocurrency address is a public identifier used to receive funds on a blockchain network. It is typically derived from a public key and can be safely shared. Anyone with your address can send you funds, but only the holder of the corresponding private key can spend them.

Address formats vary by network and may include version prefixes and checksums to reduce errors. For example, Bitcoin Cash uses the CashAddr format (q... or p...), while Bitcoin uses Base58Check (1..., 3..., bc1...).

Example 1.1 - Example Formats
  • Bitcoin (BTC): bc1qxy2kg... (Bech32)
  • Bitcoin Cash (BCH): qq123... or bitcoincash:qq123...
  • Ethereum (ETH): 0xabc123... (hex, checksummed)

caution
  • Double-check network and format—sending to the wrong network may permanently lose funds
  • Avoid reusing addresses when possible for improved privacy
  • Never share private keys or seed phrases; addresses are safe to share, keys are not
