A tied vote battle goes to a Final Salvo. A Final Salvo is a set of short voting windows called shots, up to 5 shots of 60 seconds each. Only free votes count in a shot, one per wallet per shot.
In a metrics battle an exact tie on points is settled by comparing market cap points, then holder points, then volume points, then Boost points. If those are level too, the battle is decided by a fixed rule on the token address, so there is always a winner for the prize. League points for a true draw are 0 for both coins.
