SDK/Namadillo: Sometimes Tx broadcast times out

[jurevans]

Sometimes users are encountering a "tx failed" error due to a timeout, even when the transactions are successful.

We need to investigate the exact cause of this, and perhaps figure out a better way to verify that a Tx either succeeded or failed. Currently we are throwing an error when our SDK integration broadcastTx() (which in turn calls process_tx() in Namada SDK) throws an error of any kind, which in turn notifies user that the Tx failed (which is obviously not accurate every time).

The namada sdk can either "send a tx and forget" or "send and wait". The first method, just send a transaction and doesn't check if it was actually included in a block (it just wait until it passes mempool validation). The second instead, waits for the transaction to be included in a block. The timeout you are experiencing is probably due not being able to tell if a tx was included in a block or not during the timeout window
