No, you cannot directly transfer USDT (Tether) to a USDC (USD Coin) wallet as they are two different types of stablecoins running on different blockchains. USDT is typically based on the Ethereum blockchain as an ERC-20 token, while USDC is also an ERC-20 token but issued by a different company. To transfer between USDT and USDC, you would need to use a cryptocurrency exchange or platform that supports the conversion between these two assets.
