Question 1

What is EIP-55 checksum?

Accepted Answer

EIP-55 is a mixed-case checksum encoding standard for Ethereum addresses. It uses Keccak-256 hashing to determine which letters should be capitalized, providing typo detection.

Question 2

Why is checksum important when pasting addresses?

An EIP-55 checksummed address provides built-in protection against accidental typos. If a single character changes, the checksum breaks, alerting you to modifications.

Question 3

When is a lowercase address still valid?

Accepted Answer

Lowercase addresses are technically valid and work fine for transactions. However, checksummed form is recommended for extra safety in important operations.
