- To validate the format of an Ethereum address, you can use regular expressions to check if the address matches the expected pattern. The format of an Ethereum address starts with '0x' followed by 40 hexadecimal characters. You can use the regex pattern '^0x[0-9a-fA-F]{40}$' to validate the address format. Make sure to use a reputable library or code snippet to perform the validation to avoid any security risks.
