According to BlockBeats, on September 13, Puff, the leading Meme token project in the Mantle ecosystem, announced that it has achieved cross-chain interoperability by upgrading to LayerZero's OFT (Omnichain Fungible Token) protocol. Currently, Puff has successfully deployed a liquidity pool on the Ethereum mainnet. This move not only improves the liquidity of tokens, but also provides a more efficient solution for cross-chain transactions, demonstrating the huge potential of blockchain technology in a multi-chain ecosystem.
