TRON Foundational Modules

The TRON Foundational Modules Substreams contains a set of modules that allow you to easily retrieve basic information from the TRON blockchain.

Modules

map_transactions

This module retrieves all the NOT failed transactions, without any more filtering.

filtered_transactions

This module uses the index_transactions cache to match the filtered transactions based on the parameters passed as input to the module.

You can directly use this module to retrieve filtered transactions:

modules:
    - name: my_module
      use: tron_common:filtered_transactions

params:
    my_module: source_account:account1

index_transactions

This module creates a cache of transactions based on:

• The contract type of every transactions.
• The contract address of every transactions.
• The owner address of every transactions that support it.
• The to address of every transactions that suppoirt it

You can use this module as a blockFilter to filter transactions based on the parameters specified above. Here's an example to filter all the USDT (TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t) transfers from TMAP4Dnyh2og7bzW6HxZfuZqRSTHsVDKRT:

  - name: my_module
    ...
    blockFilter:
      module: index_transactions
      query:
        string: (contract_type:TriggerSmartContract && contract_address:TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t && from:TMAP4Dnyh2og7bzW6HxZfuZqRSTHsVDKRT)
