PYTHON - decoding terra transaction data

Question

I'm trying to get all transactions info from the Terra block.

The transactions ale encoded in base64, after I decode them I get a byte string.

However I'm unable to decode the byte string.

Any idea how to decode this to get the transaction details in json?

Answer 1

It seems to me, that this is possible with terra sdk. And the overall code will be something like:

from terra_sdk.client.lcd import LCDClient
from terra_sdk.core.tx import Tx
terra = LCDClient(chain_id="columbus-5", url="https://lcd.terra.dev")
block = terra.tendermint.block_info()
tx = block['block']['data']['txs'][0]
tx = terra.tx.decode(tx)
Tx.from_proto(tx)

However right now there are some bugs in the SDK itself, but the maintainer promises these will be fixed ASAP.
