Read a burn transaction yourself

1. Open the transaction link. Example (a Base burn from the latest window): 0x649034d27f....
2. Find the token transfer line: it shows from, to and the amount of SHIB.
3. Check that "to" is one of the tracked burn addresses and that the token contract is the SHIB contract you expect.
4. Check the timestamp. The Burn Showdown uses one fixed window for both chains.

That amount is in SHIB. Any dollar value you see elsewhere depends on the price used and is an estimate.
