From a technical point of view, the exchange between networks is not just a transaction. This is an operation associated with changing the token storage platform: from solana to tron. Both standards issue Tether (usdt), which is a stablecoin tied to the dollar, but they operate in different infrastructures. In the sol network, although the speed is high, there is still instability of fees, especially under increased load. In contrast, trc20 remains the most profitable and predictable solution for storing and exchanging usdt, thanks to almost zero costs and lightning-fast processing of transactions.
