## Overspend Account

Are you sure `algod_client` is connected to testnet?  
Are you sure your transaction does not attempt to send more than 20 algos?

Try to go to [www.a-wallet.net](http://www.a-wallet.net/), in the settings set the testnet, import the account and try to do the transaction.

## Additional Information

I’m assuming you want to be on TestNet, as 3YQ4XKUUELUN64C3PSV5BIF42BWOQ6V76X55IYHIJDOM6DRBO6A2A2BFVU has 20 Algos only on TestNet.  
Assuming that:

- You installed the node following [Install a node - Algorand Developer Portal](https://developer.algorand.org/docs/run-a-node/setup/install/)
- The goal command is in the PATH (i.e., you can type `goal` and get an answer).
