Let's talk about copycat coins and coins with the same name.
The most reliable basis for distinguishing on-chain tokens is the contract address; on Solana, it’s called the Mint address.
Honestly, I only came to understand this later: for so-called "second-generation" or "upgraded" new coins, first check the original project’s official channels to confirm whether such a plan exists.
On Binance, when trading $DOGE , you don’t need to worry about the contract address, but on-chain there are countless tokens called DOGE. Current price: 0.08079.
The underlying logic can help you avoid some pitfalls, but it can’t replace risk control.

Stay calm and don’t get carried away.
