Yala officially only deployed on Ethereum, Base, and Solana, but a hacker managed to mint 90 million fake tokens on Polygon and successfully sent 30 million of them to the legitimate contract on Solana using the LayerZero cross-chain bridge for dumping. So far, the address has sold $14 million worth, with $16 million still unsold. It seems like the hacker somehow tricked the cross-chain bridge, even though Yala's official website emphasizes partnerships with multiple professional cross-chain security companies to 'address all aspects of bridge security.'
