'Axie Infinity' is a P2E (Play to Earn) game where you can earn money just by playing. Developed by Vietnam's Sky Mavis and released in March 2018, it has gained popularity in the Philippines, and some people are living only on the income earned from this game.

On March 23, 2022, from the side chain Ronin Bridge used in this 'Axie Infinity', the virtual currency Ethereum 173,600 ETH (about 72 billion yen) and stablecoin 22.5 million USDC (about 3.1 billion yen) ) Was stolen. The attacker used the hacked private key to make an unauthorized withdrawal. The situation was discovered by a user's contact saying '5000 ETH cannot be withdrawn from Ronin Bridge'.

Most of the stolen cryptocurrencies are still in the hands of attackers, and several exchanges are offering cooperation to prevent the outflow of funds.
