Catizen's token $CATI will arrange a parallel token relationship between the TON blockchain and the Mantle blockchain, each with a maximum supply of 1 billion, and a lock-up mechanism to maintain a total of only 1 billion. Currently, the cross-chain of $CATI can be completed on the Bybit exchange. The balance between the two chains is executed through mutual lock-up contracts. For example, if Catizen airdrops 10 million $CATI to Mantle chain game users, then 990 million of the 1 billion CATI on the Mantle chain will enter the lock-up contract, and 10 million of the 1 billion CATI on the TON chain will enter the lock-up contract to ensure that the total circulation of the two chains is always maintained at the upper limit of 1 billion.
