Yala officially deployed only three chains: Ethereum, Base, and Solana. However, hackers minted 90 million fake coins on Polygon and successfully sent 30 million of them to the legitimate contract on Solana using the LayerZero cross-chain bridge for sale. Currently, that address has sold 2 million dollars worth and still has 16 million dollars left unsold. It seems that the hackers managed to deceive the cross-chain bridge somehow, while Yala's official website emphasized its collaboration with several professional security companies for cross-chain bridges to "address all aspects of bridge security."
