Greyhounds are running on the Polygon Blockchain!
Breed, train, race to win money on your way to podium glory with your very own NFT Greyhound collection.

About the collectIon

Muzzle Run is a collection of NFT greyhounds racing in the Metaverse. Hounds have a unique combination of physical attributes based on rarity. The rarer the trait, the faster the hound!

While the rarest traits have the fastest base attributes, any hound has the potential to be a champion thanks to randomized performance enhancements with training.

How do I get my first hound?

Racers will be airdropped to anyone who signs up before 30 August 2022.

From 1 September you will be able to mint a Breeder (until sold out). All minted Muzzle Run NFT's are available for trading on the secondary market Opensea.

Is there a limited supply?

Breeders have a limited supply of 10,000. Once they have all been minted, that's all the breeders that will exist in the ecosystem for ever! There are 107 different types to collect.

Racers have an unlimited supply, but consist of 856 types for a full collection that include different traits based on a rarity percentage.

How do I know if I have a fast hound?

Every hound type has different performance attributes based on their physical traits. As a rule of thumb, the more rare traits your hound has then the faster it will be. Each hounds performance attributes can be viewed inside your kennel or on Opensea and can be increased with training.

How do I breed a hound?

Users who own a Breeder can produce Racers by paying a breeding fee each time they wish to breed a new hound.

How do I earn money?

Breeding - If you own a Breeder you can produce Racers and sell them on Opensea.

Racing - There will be pay to enter races and free tournaments that will award Matic prize pools.

As the game evolves more ways to earn crypto will be created.
