Use . Submit a move
Pay someone's gas.
A stealth address with no ETH can still move its SHROUD: its holder signs, and anyone submits the signature here and pays the gas. The tip it names goes to whoever submits it.
Read this first
The wallet that submits a move becomes linked to the stealth address it moves for, publicly. If the stealth address is yours, submit from a friend's wallet or from another stealth address of yours that holds ETH, not from your main wallet.
A signed move is a standing offer until its deadline: anyone who sees it can submit it and take its tip. The terms are fixed by the signature: whoever submits cannot change where the SHROUD or the ETH goes, nor raise the tip.
The page checks the signature, the deadline, the nonce, the balance and, for a sale, the price now, then rehearses the transaction for free before your wallet is asked.
