Bech32アドレスエンコーダー/デコーダー

Bech32アドレスエンコーダー/デコーダー

Encode, decode, and validate Bitcoin SegWit addresses using the Bech32 (BIP 173) and Bech32m (BIP 350) specifications. Instantly verify checksums, identify address types (P2WPKH, P2WSH, P2TR), and convert between hex witness programs and human-readable addresses.

使い方

Decode: Paste a Bitcoin SegWit address to see its human-readable part, witness version, witness program (hex), address type, encoding format, and network.

Encode: Enter a hex witness program, select the network and witness version, and generate a valid Bech32 or Bech32m address.

Validate: Paste multiple addresses (one per line) to batch-check validity and identify each address type.

特徴

• Full BIP 173/350 Support – Handles both Bech32 (SegWit v0) and Bech32m (SegWit v1+ / Taproot) encoding
• Address Decoding – Extracts HRP, witness version, witness program, and detects P2WPKH, P2WSH, and P2TR types
• Address Encoding – Generates valid addresses from hex witness programs with proper checksums
• Batch Validation – Validate multiple addresses at once with per-line status reporting
• Network Detection – Supports Bitcoin mainnet (bc1), testnet (tb1), and signet addresses
• クライアント側処理 – All encoding and decoding runs in your browser with no data sent to any server
