What is LINE Mini Dapp? Inside LINE's Web3 Ecosystem With Kaia and Bitget Wallet

What is LINE Mini Dapp? It’s your gateway to the Web3 world — right inside LINE Messenger — with just a single tap. No app downloads, no external wallets, no blockchain knowledge needed. Unlike traditional dApps that can feel complex and disconnected, LINE Mini Dapp is designed to operate smoothly as a native feature within LINE, making Web3 as easy as chatting with friends.

This groundbreaking ecosystem is developed by LINE NEXT and powered by Kaia Blockchain — two major forces shaping the future of Web3 in Asia. Users can earn tokens, receive NFTs, and enjoy games and Web3 utilities — all gas-free. Meanwhile, Bitget Wallet acts as the exclusive wallet for storing assets, receiving rewards, and seamlessly joining campaigns — all within the familiar LINE environment.

Bridging convenience and technology, Web2 and Web3, this article will take you deep into the world of LINE Mini Dapp — how it works, why it’s a game-changer, and how you can become an early pioneer in this new Web3 era.

What is LINE Mini Dapp and How Does It Work?

Definition and Ecosystem Overview

LINE Mini Dapps are ultra-lightweight Web3 applications that run directly inside LINE Messenger without the need to download or install anything — and without needing an external wallet. Unlike traditional dApps that require MetaMask and a Web3 browser, these Mini Dapps offer a “Web2.5” experience — where users interact with blockchain invisibly.

The entire LINE Mini Dapp ecosystem is powered by Kaia, a unified Layer-1 blockchain merged from LINE’s Finschia and Kakao’s Klaytn. Its tight integration with LINE Messenger — which boasts over 200 million users — makes Mini Dapps a huge leap forward in bringing Web3 to the masses. In campaigns and user guides, the term "LINE Mini Dapp" has become the go-to phrase to describe these user-friendly, accessible decentralized apps.

Why It Matters for Web3 Accessibility?

The biggest strength of LINE Mini Dapp is that it allows anyone to experience Web3 without needing to understand blockchain or cryptocurrency.

• No app downloads, no separate wallet required.
• No gas fees – the system covers all transaction costs.
• Real rewards: users can receive tokens or NFTs by playing games or using services within the Mini Dapps.

From social games like Bombie to wellness apps like Superz, every Mini Dapp is designed to feel like a natural LINE feature. This ecosystem is currently expanding rapidly across Japan, Taiwan, and Thailand — enabling millions of users to experience Web3 with just a few taps.

What is LINE Dapp Portal and How Is It Different?

LINE Mini Dapps are standalone decentralized applications inside LINE Messenger, usually focused on games, utilities, or social interactions. In contrast, the LINE Dapp Portal is a centralized hub — a discovery platform for browsing, accessing, and managing multiple Mini Dapps at once.

Think of Mini Dapps as individual small apps, while LINE Dapp Portal is the “App Store” of LINE’s Web3 ecosystem. Users can access it via the Home tab or an official account, and launch any Mini Dapp with a single tap.

How Kaia Wave Supports LINE Mini Dapp Developers?

LINE NEXT and Kaia Foundation: Tools for Web3 Builders

Behind the rapid growth of the LINE Mini Dapp ecosystem is the Kaia Wave program — a strategic initiative by LINE NEXT and the Kaia Foundation, designed to empower global developers. At its core is the Kaia SDK (Software Development Kit) — a robust tool that allows teams to build blockchain-integrated Mini Dapps without needing deep Web3 expertise.

But it goes beyond tooling. Kaia Wave also offers comprehensive support: gas fee sponsorships, marketing aid, and investment connections within LINE and Kaia’s extensive ecosystem. Each Mini Dapp becomes more than an app — it becomes part of an expanding Web3 network where developers can build, launch, and scale directly inside LINE Messenger — where millions of users are already active.

Top LINE Mini Dapp Projects Built With Kaia Wave

Several Kaia-powered Web3 games have already launched successfully under the Kaia Wave program, including:

• Bombie: A viral social mini-game from Pluto Studio with over 12 million users — currently the top revenue-generating app in the LINE Mini Dapp ecosystem. It’s also the first to launch a token ($BOMB).
• Superz: A wellness app that rewards users with Web3 incentives — designed for users unfamiliar with crypto.
• Captain Tsubasa -RIVALS- on LINE: A football game adapted from the iconic manga, now available as a Mini Dapp. Fans can interact and earn token rewards.
• TOFU Story: A soft-toned Web3 adventure game with a unique character system, offering a rich RPG experience inside LINE.

These Kaia-based Dapps showcase not just developer creativity, but also the flexibility and effectiveness of the Kaia Wave program in powering the broader LINE Web3 ecosystem.

How to Use LINE Mini Dapps: Games, Rewards, and Wallet Access?

Earn Tokens and NFTs With LINE Mini Dapps – Gas-Free

One of the most appealing features of LINE Mini Dapp is its built-in rewards system. Users can earn token rewards without paying gas fees, join in-game campaigns, and receive NFT airdrops — all with just a few simple actions. There’s no need to install a wallet, use an exchange, or pay transaction fees anymore. Now, anyone can receive Web3 rewards simply by using LINE Messenger.

A key enabler of this frictionless experience is Bitget Wallet. Thanks to its gas-free Web3 wallet integration and automatic reward distribution, Bitget lowers the barrier for everyone to access Web3 utilities with ease.

Step-by-Step: Accessing Mini Dapps in LINE Messenger

Getting started is simple:

1. Open LINE Messenger and search for Dapp Portal in the Official Account (OA) section.

   

2. Add Dapp Portal as a friend and open the chat to access the Mini Dapp feature.

   

3. From the main interface, select the Mini Dapp you want to explore — it will launch directly within LINE. (In this example, we choose Fate War.)

   

4. Connect your Bitget Wallet if you wish to store rewards, manage assets, or make transactions.

   

5. Start completing tasks or playing games — and enjoy gas-free rewards via the built-in wallet, including tokens, NFTs, or in-game items.

By offering Web3 access directly through LINE, the entire blockchain process is simplified, delivering a smooth and intuitive experience — just like using any regular LINE feature.
