Axie Infinity is an non-fungible token-based online video game developed by Vietnamese studio Sky Mavis, known for its in-game economy which uses Ethereum-based cryptocurrencies.

Players of Axie Infinity collect and mint NFTs which represent axolotl-inspired digital pets known as Axies. These creatures can be bred and battled with each other within the game. Sky Mavis charges a 4.25% fee to players when they trade Axies on its marketplace.

As of September 2021, most Axie Infinity players are from the Philippines.

Axie Infinity is built on the Ronin Network, an Ethereum-linked sidechain developed by Sky Mavis. In March 2022, hackers compromised the Ronin Network, stealing approximately US$620 million worth of cryptocurrency from the project.
