The correct answer is:
swapExactTokensForTokens(uint256,uint256,address[],address,uint256)
This function selector 0x38ed1739 corresponds to the
swapExactTokensForTokens function in the Uniswap Router contract.
Transaction Data Decoded:
Function Selector: 0x38ed1739
amountIn: 37889.000768 ROOT
amountOutMin: at least 0.22130045 WETH
path: [USDT, WETH] trading path from USDT to WETH
to: 0x6a5104e426158849a2fc9749561fab575604c62a (recipient address).
Note that this is the attacker's wallet address that will receive your assets

Why This Matters:
In Ethereum transactions, the function selector is the first 4 bytes of the transaction data,
which is the first 4 bytes of the keccak256 hash of the function signature. For example, the
first 4 bytes of the hash of
"swapExactTokensForTokens(uint256,uint256,address[],address,uint256)" is 0x38ed1739.
Phishing attacks might trick you into signing a transaction that claims to do one thing but
actually calls a completely different function. Always verify what function you're actually
calling and what the parameters are.
In this example, the transaction appears to be swapping tokens on Uniswap, but the recipient
address might be controlled by the attacker rather than your own address.
How to Protect Yourself:
1. Use wallets that support transaction decoding, such as MetaMask.
2. Carefully check transaction data and parameters before signing any transaction.
3. If you're unsure what a transaction is doing, don't sign it.
4. Use hardware wallets, which typically display more details about transactions.
