The tron.assets.trc20_balances contains block-level balances of TRC20 tokens. Each entry in the model corresponds to a specific event/transaction that causes a balance change in a particular asset at the block level. This means a new data entry is only created when a transaction alters an asset’s balance at the block level.
  • For example, if a wallet receives 1 USDC in 2020 and experiences no further changes until yesterday, the model will have two entries: one for the initial receipt in 2020 and another for the recent change.

​
Model Caveats

The tron.assets.trc20_balances dataset is derived by calculating the net effect of all token transfers for each account, specifically by summing all incoming transfers (credits) and subtracting all outgoing transfers (debits). This approach is used as the Tron blockchain does not support point-in-time balance queries for TRC20 contracts. As a result, the model is subject to the following caveats that will result in discrepancies in the balances:
  • Balance Changes Without Transfers: Certain operations may modify token balances without generating a transfer event. This can occur through direct contract interactions that adjust balances internally, bypassing the standard transfer log mechanism. Some older TRC20 contracts or legacy blocks may not emit standard transfer events. As a result, balances from these contracts might not be accurately captured.
  • Rebasing Tokens: Rebasing tokens automatically adjust their total supply, which can impact individual balances without explicit transfer events. This can lead to discrepancies in balance calculations that rely solely on transfer events.
  • Null Balances: Zero address T9yD14Nj9j7xAB4dbGeiX9h8unkKHxuWwb will show negative balances for most TRC20 tokens due to the way the event logs represent zero address as the sender of assets during token mints, despite the address not holding the assets previously.
