Is there any way to accomplish the same functionality with version 4 in case I run into cross compatibility issues?

```python
return Seq([
InnerTxnBuilder.Begin(),
InnerTxnBuilder.SetFields({
TxnField.type_enum: TxnType.Payment,
...  
```

#### Transaction Signing Issues
**Date:** Jun 14, 2022

For whatever reason the server was returning the compiled TEAL code but slightly altered, returning the binary version of the compiled code instead (and going through the lsig account signing) fixed this. Thanks all!

That did the trick thanks, so now I’m running this code:  
```javascript
let txgroup = algosdk.assignGroupID(txns);
let buyCallBase64Tx = AlgoSigner.encoding.msgpackToBase64(buyCallTx.toByte());
let payBase64Tx = AlgoSigner.encoding.msgpackToBase64(payTx.toByte());
...  
```

Hey folks,  
I’m building 3 transactions to be added to a txgroup, the first two transactions need to be signed by the user and the 3rd by a logic signature account. My code looks like that (I’m using algosigner for allowing users to sign txs on the client side).

Thanks [@janmarcano](https://forum.algorand.co/u/janmarcano) , adding const AlgoSigner = window.AlgoSigner; on my component seems to have fixed the issue.

Hello,  
I’m currently using a server (nodejs) to generate transactions and then pass them to the client (react) to sign with AlgoSigner and submit with algosdk. I have an issue casting the transaction from object (as fetched from the server) to a transaction type so I can use algosdk and AlgoSigner...

Hey folks,  
I’ve been looking at building a simple NFT marketplace (without a bidding functionality) and I’m following this tutorial: [Creating an NFT Marketplace | Algorand Developer Portal](https://developer.algorand.org/tutorials/creating-an-nftmarketplace/)
