Ethereum Address Input
About EIP-55 Checksum
EIP-55 is the Ethereum checksum address standard. It uses mixed-case hex encoding to embed a checksum directly in the address format.
The checksum is computed by taking the Keccak-256 hash of the lowercase address (without 0x prefix). Each alphabetic character in the address is uppercased if the corresponding nibble of the hash is ≥ 8.
Always use checksummed addresses to prevent typos and ensure compatibility with wallets and smart contracts.
