Crash games met TRON
The de facto low-fee network for USDT transfers.

TRON isn't typically where crash-game contracts themselves run, but it's become the dominant network for moving USDT specifically — TRC20 transfers usually cost under a dollar and confirm within seconds to a few minutes, which is why most crypto casinos list "USDT (TRC20)" as a distinct, often-preferred deposit option.
The security model differs meaningfully from Ethereum's — TRON runs on a smaller set of block producers — but for a stablecoin transfer rather than a smart-contract game, most players weigh that less heavily than the fee and speed advantage.
