FAQ
- How do I check a Ethereum address is valid?
- Paste it into the checker on this page. It verifies the checksum and the encoding for Ethereum and says which address type it is, or why it fails.
- What does a Ethereum address look like?
- 0x + 40 hex characters. Try it with the public example 0xD8dA6BF26964AF9D7EdD9E03e53415D37aA96045.
- Is it safe to paste my Ethereum address?
- Yes. An address is public. The checker only reads the string you paste; nothing is stored, and it never asks for a private key or seed phrase.
