Most questions are about one of four things: which options to switch on, why a gas estimate moved, how verification works, or a transaction that did not confirm. Send the detail and you get a direct answer rather than a ticket number.

Worth checking first

My fee transaction is stuck as pending
It is under-priced for the current base fee rather than lost. Speed it up in your wallet, or cancel it by replacing it with a zero value transaction to yourself at the same nonce and a higher gas price.
The gas estimate changed between two visits
The estimate multiplies the gas your configuration needs by the current gas price. The gas units barely move, the gas price moves constantly.
I picked the wrong decimals
Decimals cannot be changed after deployment. The fix is a new deployment with the right value, which is exactly why a rehearsal on Sepolia is worth the ten minutes.
My wallet will not connect
Check that it is unlocked and on Ethereum mainnet. If a previous session is stuck, disconnect this site inside the wallet and try again. On mobile, open the site inside the wallet browser.
