Kaia Ecosystem Evolution: On-Chain Rise Paradigm Centered on Mini Dapp

1. Overview of Kaia Blockchain Ecosystem

1.1 Background and Team

Kaia is a new ecosystem formed by the merger of Kakao and LINE's two major blockchain projects, Klaytn and Finschia. Klaytn was initially launched by Kakao Group's subsidiary Ground X in June 2019, with early governance alliances including well-known Korean companies such as LG Electronics, Celltrion, and Netmarble. Finschia originated from LINE's LINK chain launched in August 2018, which was later renamed in 2022 and established a foundation for operations. In August 2024, the two chains officially merged into the Kaia mainnet, which is managed by the newly established Kaia DLT Foundation.

Kaia aims to be an L1 public chain focused on large-scale applications, featuring high TPS and developer-friendly characteristics. Its core advantage lies in a mature SDK system and deep integration with mainstream social platforms, supporting various decentralized applications to run directly on platforms like KakaoTalk and LINE. As a public chain based on BFT consensus, Kaia has been highly optimized to achieve enterprise-level reliability and performance standards.

1.2 Important Development History

| Time | Event Description | |------|----------| | June 2019 | Ground X launched Klaytn mainnet | | December 2022 | LINE launched the Finschia mainnet | | April 2023 | LINE established the Finschia Foundation | | August 2024 | Kakao and LINE jointly launched the Kaia mainnet | | April 2025 | Kaia Foundation announces investment from 1kx and several other institutions | | May 2025 | Tether issues USDT on-chain on the Kaia chain |

1.3 Main Features

Kaia adopts a layered node architecture, including core units, consensus nodes, proxy nodes, and endpoint nodes. The network uses an improved Byzantine Fault Tolerance consensus algorithm to achieve a 1-second block time and instant finality, with a theoretical peak throughput of up to 4000 TPS. Kaia is EVM-compatible, supports Ethereum ecosystem smart contracts, and integrates with various cross-chain bridges.

Kaia closely integrates with the LINE instant messaging ecosystem, supporting developers to directly deploy native Dapps within the chat application through SDK/API. In May 2025, Tether officially issued native USDT on the Kaia on-chain, allowing users to directly use stablecoins in their daily chat interface.

Kaia adopts a sustainable token economic model, with the native token KAIA used for paying transaction fees and incentivizing network operation. Kaia supports on-chain governance, allowing the annual inflation rate and fee model to be adjusted based on community resolutions. Compared to other mainstream public chains, Kaia focuses on the Asian market, bringing the massive user base of Kakao and LINE into the Web3 ecosystem, providing a unique advantage in promoting large-scale blockchain applications.

2. Progress in Ecological Construction

2.1 Kaia Wave Plan and Mini Dapp Ecosystem

In August 2024, the Kaia mainnet will be launched and the Kaia Wave program will be released. This program is jointly developed by Kaia and LINE NEXT, enabling developers to build Mini Dapps for LINE Messenger users through the NEXT WEB SDK. The first batch of Mini Dapp projects will be launched in the first quarter of 2025, covering multiple niche segments.

Kaia has jointly launched the Mini Dapp Growth Competition with LINE Dapp Portal, focusing on the project's monthly active users and on-chain token holder rise. So far, the event has successfully held two sessions, continuously driving the accelerated growth of the Kaia on-chain Mini Dapp ecosystem.

The Dapp Portal, accessible directly through LINE Messenger, serves as a Dapp directory and entry point, providing users with a one-stop service experience that includes Dapp discovery, downloads, usage rewards, and virtual asset trading.

2.2 Kaia Stablecoin Plan

In May 2025, Kaia and Tether reached a strategic partnership to natively issue USDT on the Kaia blockchain. These USDT are deployed in the form of native contracts and are directly managed and issued by Tether, ensuring real-time parity with "1:1" dollar reserves. The first batch of native USDT has been integrated into the Mini Dapp ecosystem within LINE Messenger, enabling the everyday use of stablecoins.

Several mainstream exchanges have successively supported the USDT-KAIA network, including Bitget, Bitfinex, Bybit, and Gate. The Kaia team is fully committed to promoting the issuance plan of the Korean won (KRW) stablecoin, and will launch a series of influential on-chain financial products and services in the future.

2.3 ecological investment progress

In April 2025, the Kaia Foundation announced that it had secured investment led by 1kx and Blockchain Capital, with participation from several well-known institutions including Galaxy Digital and IDG Capital. This collaboration will greatly assist in the market promotion of LINE NEXT and Mini Dapp services, and further strengthen Kaia's influence in the global market through shared business networks.

2.4 ecological strategic cooperation

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

• November 2024, integration with the Dune platform to achieve on-chain data visualization
• In January 2025, in collaboration with Fireblocks, we will provide secure asset custody and cross-border payment support for ecosystem partners.
• In January 2025, establish a strategic partnership with KuCoin to provide priority listing review and investment support for Mini Dapps.
• In February 2025, in collaboration with Republic, providing advisory support for Mini Dapp developers.
• In February 2025, establish a strategic partnership with MEXC to jointly identify and support promising Mini Dapps.
• In April 2025, in collaboration with Travala, the KAIA token will be integrated into its payment system.
• In April 2025, integration with Team Finance will be completed to support project parties in quickly creating token lockup and other functions.

2.5 Developer Support and Community Building

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

• Conducting lectures and training courses in multiple educational institutions in Singapore in early 2025
• Join Kaito's Yapper Leaderboard in April 2025, launching a prize pool to incentivize community creation.
• The DEX Scanner feature will be launched in the Dapp Portal in April 2025.
• Open pre-registration channel for developer training camp in May 2025
• The Kaia Agent Kit development suite will be launched in June 2025, supporting the construction of AI-driven on-chain Agents.
