📦 Transaction Decoder

Decode Sui transaction bytes: sender, gas, inputs and commands, plus the transaction digest.

Transaction bytes (base64 or hex)

Paste the base64 TransactionData that wallets sign (also accepted: transaction kind bytes built with onlyTransactionKind). The digest is the transaction’s ID: BLAKE2b-256 of “TransactionData::” followed by the bytes, in base58. Pure inputs are raw BCS without a type, so their meaning is a best guess from their length and how commands use them.
