Scheduled launch
Sign your launch now, launch it at EU open (09:00 Amsterdam), NA open (09:30 New York) or any time in the next 7 days. Your key stays in your wallet; the server only holds the signed transaction and the time.
1. Deploy nonce
No walletA launch you sign now must still be valid at the send time. A normal transaction expires after about a minute; one signed against your own deploy nonce stays valid until it lands or you move the nonce. That is what makes scheduling possible without handing anyone your key.

What happens at the send time
The server holds only your signed launch and the time. It cannot change it: it can send exactly those bytes, once, or not at all. Your key never leaves your wallet.
Balance too low at that moment: the server checks your balance against the cost first and does not send the launch. Nothing is spent and your nonce stays intact. The server retries every 5 seconds for 2 minutes, so a top-up in that window still launches. After that the job is marked failed and the signed launch is deleted; sign it again to reschedule.
Cancel: Cancel deletes the signed launch on this server. Advancing the deploy nonce makes every launch signed against it invalid everywhere; that is the cancel that does not depend on us.
