X-Metaverse is a blockchain game developed by 3D and can run on Android, iOS and PC. All game content items and characters are based on blockchain tokens and NFTs. The visual effects and gameplay of X-Metaverse are inspired by StarCraft and Star Wars. Players will be immersed in the vast space, spend time cultivating different races, upgrade spaceships, reach more galaxies, and collect rare materials. The most exciting thing is that you can earn cryptocurrency with other players through actions such as conquering, exploring, competing, mining, producing, breeding, and fighting.
Contract name (X-Metaverse) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.
Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.
Not a direct threat, but may indicate unreliable intentions of developer. Both name and ticker of current token are widespread, i.e. common across multiple tokens. This is slightly suspicious
