With the development of blockchain technology, the financialization of game assets has always been one of the tracks most concerned by the outside world. Previously, although many blockchain games have been devoted to this exploration since the birth of the encryption cat, blockchain games have been tepid due to the congestion of Ethereum network. Until last year, the development of many side chain technologies has given new development space to blockchain games. For example, Axie Infinity uses its own ronin side chain, which makes the interaction of game assets more convenient and faster. In this way, game assets can better combine with financial products and join financial scenes such as transaction, pledge, lease, loan and so on.
