Interpretation
How Crypto Wallet Validation works
The Wallet Validator checks whether a cryptocurrency address matches the expected format for its target blockchain: length, character set and prefix conventions only. It is a format check — it does not verify a checksum, a private-key match, or whether the address has funds or history. Always confirm an address against the sending wallet before transferring.
