Formula Used
1. Base58Check checksum: Convert the address to bytes, split payload and checksum, then confirm checksum = first 4 bytes of SHA-256(SHA-256(payload)).
2. Bech32 checksum: Expand the human-readable prefix, append data values, and compute the polymod remainder. A valid remainder matches the expected Bech32 constant.
3. EIP-55 checksum: Lowercase the hexadecimal address, hash it with Keccak-256, then uppercase each letter when the corresponding hash nibble is at least eight.
4. Validation score: The tool assigns points for allowed characters, correct length, accepted prefix or version, and checksum success to summarize address quality.

Frequently Asked Questions
What does Auto Detect do?
Auto Detect checks each entry against all supported network rules, then reports the first strong match. It is helpful when users receive an address without a clear network label.
Why can a format look correct but still fail?
Many wallet strings have valid lengths and symbols but fail checksum math. That usually means a typo, missing character, wrong case, or an address copied from another network.
What is strict mode?
Strict mode requires stronger checksum behavior. For example, mixed-case Ethereum entries must pass EIP-55, while lowercase or uppercase forms may be marked as weaker if checksum casing is not present.
Does a valid address guarantee funds will arrive?
No. Validation only confirms the string matches technical rules. It cannot confirm account ownership, exchange memo requirements, token compatibility, or whether a destination can receive a specific asset.
Why does the tool show a score?
The score summarizes how many rule groups passed, including character set, length, prefix or version, and checksum. It helps users compare borderline entries quickly during reviews.
Can I validate several addresses together?
Yes. Switch to Batch Validation or simply paste multiple lines. The calculator processes each line separately and creates one downloadable row for every checked address.
Which networks are supported here?
This version supports Bitcoin, Ethereum or EVM, Litecoin, Dogecoin, and Tron. Each network uses different character rules, prefixes, and checksum methods.
Should I still verify the destination manually?
Yes. Compare the address with the intended source, confirm the network inside your wallet or exchange, and send a small test amount when accuracy matters.
