Hi all,

Is there a standard way to serialize an unsigned transaction (such that it is supported in Python/TS/Rust SDKs). A few things I considered, but didn’t quite work:

- In the TS SDK, calling `build` to get the BCS representation requires (TransactionBlock.ts#L524) the transaction to be “fully prepared” (all objects resolved, etc.), which I’d rather avoid, since I want to capture the transaction in its original form (for example, as it’s passed from a dApp to a Wallet).
- The TS SDK also supports a custom serialization (TransactionBlock.ts#L484), but that seems to be TS-specific and is not compatible with other languages.

I’d be happy if anyone has a suggestion?

Best,  
Dima

Hi @dimakogan Transactions can be serialized by calling `tx.toJSON()` on the transaction instance.
