Why are there Different USDT Addresses?

Tether operates across multiple blockchains, and each of these networks has its own unique architecture. This is why USDT has different contract addresses depending on the blockchain it's hosted on. For instance, Tether on the Ethereum network is an ERC-20 token, while on Solana, it's an SPL token. Each version of USDT is unique to its host blockchain, which is why they have different contract addresses.

Can I Add TRC20 USDT to MetaMask? 

The straightforward answer is no, you can't add TRC20 USDT to MetaMask. The reason is that the Tron Network, which hosts TRC20 tokens, is not Ethereum Virtual Machine (EVM) compatible. MetaMask is designed to support EVM-compatible blockchains, which means it doesn't support the Tron Network. If you're looking to store or transact TRC20 USDT, you'll need to use an alternative wallet that does support the Tron Network. Trust Wallet is one such option that you can consider for this purpose.
