That's right! I forgot about TRON a great and fast blockchain. But why didn't I see DEFI on it? I haven't heard anything about it.
The Tron blockchain is different from the ETH, BNB and MATIC mate blockchains, and the Tron blockchain has been around for a very long time in cryptocurrencies before DeFi, so it certainly doesn't tie it to anything except coins like USDT which has added several blockchains to it including TRC20.
