Lock a bag of any graduated coin and enter the arena as that ticker. Your bag is your body — the live price sets your size, so pumps make you huge and dumps make you prey. Eat a smaller ticker and their bag is yours.
Your bag sits in an escrow that only your wallet can sign out of. There is no admin key that can move it out — read withdraw in the program.
When you get eaten, the server can only move your bag to the player who ate you, inside the same match. It can never withdraw. Rake is capped in code at 5%.
Hit request_exit from your wallet. After a short grace the server can't touch you and your bag is yours to pull. Nobody's coins depend on our uptime.
