A ticker is a nickname. The contract is the thing.
A ticker is letters people put on a chart: USDC, WETH, or whatever four-letter word is trending. Anyone can reuse those letters.
A token contract is a 0x address on a chain. That is what you actually hold or swap. Two contracts can share a ticker and have nothing else in common.
Kedge Alert watches the address you paste. We do not watch a name.
