Ethereum Address Format Checker explained
Check length, hexadecimal structure and EIP-55 checksum case for an Ethereum/EVM public address. All-lowercase addresses may be structurally valid without checksum protection; this cannot identify the recipient.
Formula or validation method
EVM addresses contain 20 bytes. Mixed-case checksums follow Keccak-256 EIP-55 conventions.
