BTC Address Validator Explained
A BTC address validator helps you confirm whether a Bitcoin address is structurally valid before you use it. The tool checks common address formats such as legacy base58, bech32, and bech32m, and it can also identify the likely network. This is useful for wallet UIs, exchange forms, payment flows, and internal tools that accept pasted Bitcoin addresses. Since Bitcoin supports multiple address encodings, validating them correctly is more reliable than using a simple regular expression. Running the validation directly in the browser makes it fast and easy to test address handling without a backend dependency.
