It’s a fully client-side web tool that decodes and visualizes the internal structure of cryptocurrency addresses. Currently supported: Bitcoin: P2PKH, P2SH, Bech32 (SegWit), Bech32m (Taproot); Ethereum / EVM: EOA addresses with EIP-55 checksum validation; USDT: ERC-20 (Ethereum), TRC-20 (Tron), Omni (Bitcoin); BNB Chain: BEP-20 (EVM-compatible).

Instead of just validating, it breaks addresses into components like prefixes, payloads, checksums, witness versions, and contract metadata (for known token contracts). It also assigns a “format score” to indicate how modern and well-formed an address format is (e.g. Taproot vs legacy).

Everything runs locally in the browser — no backend, no APIs, no address storage.

I built this primarily as a debugging and learning tool. Feedback from people who’ve worked with address parsing, wallets, or crypto infra would be especially welcome.
