Input Struct

[kthenurseone]

Hi, I was using your library like 1 year ago and I was calling this method to find permit nonce value:

def getPermitNonce(wallet, checkToken):
    r = requests.get(f"https://{api_url}/api?module=account&action=txlist&address={wallet}&startblock=0&endblock=9999999999999&page=1&offset=0&sort=desc&apikey={random.choice(api_keys)}")

    for tx in r.json()["result"]:
        try:
            if "0x3fc91a3afd70395cd496c647d5a6cc9d4b2b7fad".lower() == tx["to"].lower() and tx["isError"] == "0":
                #print(tx["hash"])
                decoded_transaction = codec.decode.transaction(tx["hash"])
                #print(decoded_transaction["decoded_input"]["inputs"][0][1])

                nonce = decoded_transaction["decoded_input"]["inputs"][0][1]['struct']['details']['nonce'] + 1
                token = decoded_transaction["decoded_input"]["inputs"][0][1]['struct']['details']['token']
                print(checkToken, token)
                if checkToken.lower() == token.lower():
                    # print(tx["hash"])
                    print(f"{token} nonce is {nonce}")
                    return nonce
                    break
        except Exception as e:
            print(e)
            pass
    return 0

but now it doesn't have "struct", is it changed ?

Hi @kthenurseone

I don't think there was ever a UR function supported by this SDK with these bits in their parameters:

• ['struct']['details']['nonce']
• ['struct']['details']['token']

Are you sure there was not some kind of enrichment after the decoding ?

As a side note, there is a method to get the permit2 nonce in the codec

@kthenurseone

Actually, the PERMIT2_PERMIT has indeed these parameters, my bad!
But you need to make sure you're looking into this particular UR function and not another one.

Hi, I found the solution by looking the tutorial(how to get permit nonce), I think you should add it to your library examples because it's not easy to find that function you already made to find permit nonce. Thank you so much. 🙏
