Kaia Ecosystem Evolution: On-chain Growth Paradigm Centered on Mini Dapp

1. Overview of the Kaia Blockchain Ecosystem

1.1 Background and Team

Kaia is the new ecosystem formed after the merger of the two major blockchain projects Klaytn and Finschia, led by Kakao and LINE. Klaytn was launched in June 2019 by Ground X, a blockchain subsidiary of the Kakao Group, with early governance members including well-known Korean companies such as LG Electronics, Celltrion, and Netmarble. Finschia was initially launched by LINE in August 2018 through its blockchain subsidiary LINE TECH PLUS, and in April 2023, the Finschia Foundation was established in Abu Dhabi. In August 2024, the two chains officially merged, launching the brand new Kaia mainnet.

Kaia aims to become an L1 blockchain focused on large-scale applications, featuring high TPS and developer-friendly characteristics. Its core advantages lie in a mature SDK system and deep integration with KakaoTalk and LINE platforms, supporting various decentralized applications to run directly on these mainstream social platforms. As a public blockchain based on the BFT consensus mechanism, Kaia has been highly optimized to achieve enterprise-grade reliability and performance standards, providing a solid underlying support for the next generation of Web3 applications.

1.2 Important Development History

• June 2019: Ground X launched the Klaytn mainnet
• December 2022: LINE launched the Finschia mainnet
• April 2023: LINE established the Abu Dhabi Finschia Foundation
• August 2024: Kakao and LINE jointly launch the Kaia mainnet
• April 2025: The Kaia Foundation secured funding led by 1kx and Blockchain Capital.
• May 2025: Tether issues USDT on the Kaia blockchain

1.3 Main Features

Kaia adopts a layered node architecture and uses an improved Byzantine Fault Tolerance consensus algorithm. The network achieves a block time of 1 second and instant finality, currently having over 50 consensus nodes, with a theoretical peak throughput of about 4000 TPS. Kaia is EVM-compatible and supports smart contracts in the Ethereum ecosystem. The platform integrates with various cross-chain bridges to enable asset interoperability with Ethereum and other chains.

Kaia closely integrates with the LINE instant messaging ecosystem, allowing developers to directly deploy native Dapps within the chat application by providing SDK/API. In May 2025, Tether issued native USDT on the Kaia chain, enabling users to directly use stablecoins for payments and cross-border transfers in their daily chat interface.

Kaia adopts a sustainable token economic model, with its native token KAIA used for paying transaction fees and incentivizing network operations. Kaia supports on-chain governance, allowing adjustments to the annual inflation rate and fee model based on community resolutions, thereby balancing token inflation with value incentives.

2. Progress of Ecological Construction

2.1 Kaia Wave Project and Mini Dapp Ecosystem

In August 2024, the Kaia mainnet was officially launched, along with the release of the Kaia Wave program. This program is jointly created by Kaia and LINE NEXT, enabling Web3 developers to build Mini Dapps for LINE Messenger users through the NEXT WEB SDK developed by LINE NEXT. The first batch of Mini Dapp projects is set to go live in LINE Messenger in the first quarter of 2025.

Kaia and LINE Dapp Portal jointly launched the Mini Dapp Growth Competition, focusing on the monthly active users (MAU) and on-chain token holders growth of projects. So far, the event has successfully held two sessions, continuously driving the acceleration of the Kaia on-chain Mini Dapp ecosystem.

2.2 Kaia Stablecoin plan

In May 2025, Kaia reached a strategic partnership with Tether, the world's largest stablecoin issuer, to issue USDT natively on the Kaia blockchain. The first batch of native USDT has been integrated into the Mini Dapp ecosystem within LINE Messenger, enabling the daily use of the stablecoin. Several major exchanges have successively supported the USDT-KAIA network.

The Kaia team is fully committed to promoting the issuance plan of the Korean won (KRW) stablecoin. The collaboration experience with the aforementioned institutions has further enhanced Kaia's credibility and professionalism in building a compliant and scalable digital currency infrastructure.

2.3 ecological investment progress

In April 2025, the Kaia Foundation announced that it has secured investment led by 1kx and Blockchain Capital, with participation from Galaxy Digital, The Spartan Group, IDG Capital, and others. The collaboration includes business strategy development, cooperation with the Kaia project, connections with traditional financial companies such as Visa, and support for content and marketing.

2.4 ecological strategic cooperation

Kaia continues to expand its strategic cooperation in data visualization, secure custody, asset circulation, scenario implementation, and funding support.

• Integrate with the Dune platform to achieve on-chain data visualization
• Partnering with Fireblocks to provide secure asset custody and cross-border payment support
• Establish a strategic partnership with KuCoin to provide priority listing review and investment support.
• Establish strategic cooperation with Republic to provide one-on-one advisory support for Mini Dapp developers.
• Establish a strategic partnership with MEXC to jointly identify potential Mini Dapps.
• Establish a strategic partnership with Travala to integrate the KAIA token into the Travala payment system.
• Integrate with Team Finance to provide features such as token locking, setting release schedules, and multi-signature management.

2.5 Developer Support and Community Building

The Kaia Foundation enhances the developer experience and stimulates community vitality through tools, content incentives, and educational promotion.

• Conduct lectures and training courses at several educational institutions in Singapore
• Join Kaito's Yapper Leaderboard, with a total prize pool of 100,000 USDC.
• Launch DEX Scanner feature in Dapp Portal
• Kaia Developer Bootcamp pre-registration channel
• Launched the Kaia Agent Kit development suite, supporting developers to build AI-driven on-chain Agents.
