Top Messaging Apps Back New Blockchain, Claiming to be World’s Fastest EVM Chain

Kaia, the new Layer-1 blockchain developed by Kakao and LINE, has officially launched its mainnet.

Promoted as the “fastest EVM blockchain globally,” Kaia boasts one-second transaction finality, minimal gas fees, and strong backing from major Asian web3 players Kakao and LINE NEXT. This launch follows the recent merger of Kakao’s Klaytn and LINE’s Finschia platforms.

With over 250 million users combined—Kakao’s dominance in South Korea and LINE’s in Japan, Taiwan, and Thailand—Kaia aims to improve web3 experiences by integrating closely with these messaging platforms.

The blockchain supports various applications, including decentralized finance (DeFi), gaming, real-world asset management, and web3 messaging.

In conjunction with its mainnet debut, Kaia is inviting developers to build mini dApps for LINE using the NEXT WEB SDK, promising enhanced user integration similar to Telegram’s native app experience.

Kaia emphasizes its low transaction latency, account abstraction, and fee delegation features, which are designed to offer a smooth user experience and reach LINE’s extensive user base across Asia.
