Vietnam-based Sky Mavis in which players collect, breed, and battle digital creatures called Axies on the Ronin sidechain. In March 2022 the game's underlying Ronin bridge was exploited for 173,600 ETH and 25.5 million USDC — approximately $625 million at the time — in what the US Treasury and FBI attributed to North Korea's Lazarus Group, making it the largest DeFi hack in history at that point. Sky Mavis subsequently raised $150 million to compensate affected users, hardened the Ronin validator set, and pivoted the game toward a land-based expansion called Homeland, though token prices and player counts have not recovered to 2021 peak levels.","timeline":[{"date":"2017-01-01","event":"Conceptual development of Axie Infinity begins by Trung Nguyen and co-founders in Vietnam.","source":"Axie Infinity Wikipedia","source_url":"https://en.wikipedia.org/wiki/Axie_Infinity"},{"date":"2018-03-01","event":"Axie Infinity officially launches; Sky Mavis formally incorporated.","source":"Axie Infinity Wikipedia","source_url":"https://en.wikipedia.org/wiki/Axie_Infinity"},{"date":"2021-06-01","event":"Daily active users surpass one million; Filipino players begin treating AXS/SLP earnings as primary income.","source":"Decrypt — What Is Axie Infinity?","source_url":"https://decrypt.co/resources/what-is-axie-infinity-the-play-to-earn-nft-game-taking-crypto-by-storm"},{"date":"2021-10-05","event":"Sky Mavis raises $152 million Series B led by Andreessen Horowitz at a $3 billion valuation.","source":"The Block","source_url":"https://www.theblock.co/post/119521/axie-infinity-nft-series-b-funding-a16z"},{"date":"2021-11-06","event":"AXS token reaches all-time high of approximately $165; daily active users peak near 2.7 million.","source":"CoinGecko / CoinLore historical data","source_url":"https://www.coinlore.com/coin/axie-infinity/historical-data"},{"date":"2021-11-01","event":"Sky Mavis grants Axie DAO temporary RPC node allowlist access to distribute gas-free transactions during peak load.","source":"Ronin Security Breach Postmortem","source_url":"https://roninchain.com/blog/posts/back-to-building-ronin-security-breach-6513cc78a5edc1001b03c364"},{"date":"2021-12-01","event":"Gas-free transaction arrangement with Axie DAO is discontinued, but allowlist access is not revoked — leaving a backdoor.","source":"Ronin Security Breach Postmortem","source_url":"https://roninchain.com/blog/posts/back-to-building-ronin-security-breach-6513cc78a5edc1001b03c364"},{"date":"2022-02-08","event":"Sky Mavis reduces SLP emissions, warning publicly of risk of 'total and permanent economic collapse' in the Axie economy.","source":"CoinDesk","source_url":"https://www.coindesk.com/tech/2022/02/08/axie-infinity-reduces-slp-emissions-to-prevent-collapse"},{"date":"2022-03-23","event":"Lazarus Group exploits the Ronin bridge, stealing 173,600 ETH and 25.5 million USDC (~$625 million) via five compromised validator keys.","source":"Ronin Chain Community Alert","source_url":"https://roninchain.com/blog/posts/community-alert-ronin-validators-6513cc78a5edc1001b03c366"},{"date":"2022-03-29","event":"Breach is discovered after a user reports inability to withdraw 5,000 ETH.
