You are reassigning a new array to chartData on each iteration, so it ends up with only the last value. Instead, you should create an empty array before the loop and push elements into it.

In ABI, any return value of a struct type will be interpreted as tuple. In your case, its type is tuple[].

The library has no clue what's your tuple is, how long it is, what's the type.

You should parse the return data by hand.

How to get TRC20 transactions to an address

Asked 2019-Dec-18 at 13:22

I am using tron web to query transactions of an address but it does not return transactions sent to that address where token transferred is TRC20.

This does not work. I want to get the transactions on an address and get both TRX, trc10 and trc20 transactions.

What am I doing wrong or how to do that?

Here is my code block:

...

ANSWER

Answered 2019-Dec-18 at 13:21

After a lot of research I found out one can easily query contract events at intervals to get transactions on that contract address and you can then filter it for the address you are watching since you cant get a webhook or websocket with your trongrid/tronweb implementation.

Here is a sample file I used to achieve this and it works great for monitoring many address even with different contract addresses.

Note: In my own implementation, this node file is called from another file and other logistics are handled in the other file, but below you see how I queried the trasfer events emitted by the specified contract

I had to study the ECDH supported key format and regenerate the keys according to new format to be able to fix this issue. There were two formats of the public key that we can use to encrypt data.
