Blockchain transactions that involve transfer of assets from one account to another are often of particular interest. One way to detect such transactions on the TRON blockchain is to apply get_tx_by_account_address() or get_tx_for_time_range() and then filter the returned results by the field contract_type (e.g., looking for the values such as TransferContract or TransferAssetContract). However, tronr also offers two dedicated functions to query the TRC-10 and TRC-20 token transfers: get_trc10_transfers() and get_trc20_transfers().
The two functions have almost identical arguments. In particular, users can specify the time range of interest with the min_timestamp and max_timestamp arguments. If no other parameters are provided, both functions will return all transfers of the respective tokens that took place within that time range:
library(tronr)
# Results contain all TRC-10 transfers that took place
# within the specified time range:
get_trc10_transfers(
min_timestamp = "1577837400000",
max_timestamp = "1577837430000"
)

Please note: the number of transactions that take place on the TRON blockchain is very large, and thus users are advised to choose
min_timestampandmax_timestampwisely. If the requested time range is too large, the maximum number of transactions returned by the underlying Tronscan API will be capped at 10000, and the processing time may become prohibitively long. Chunking the time range of interest into smaller periods can help to avoid gaps in data in such cases. However, users would have to implement their own logic for that.
