Integration Grants Application '25: Tubbly

Application Introduction
Tubbly is a mobile Move2Earn app that rewards users for walking with crypto tokens and real-world benefits. With over 100k user, mostly from Web2 - we’re now expanding into blockchain ecosystems to bridge the gap between daily activity and crypto adoption.

Tubbly brings a new user acquisition channel to Conflux by onboarding Web2 users through real-world activity, walking. Users collect tokens on a map by moving in the physical world, then interact with Web3 features like wallets, airdrops, and in-app token utility.
We solve a key challenge in Web3 gaming: reaching and converting mainstream users. Instead of relying solely on traditional gaming channels, we engage users through lifestyle behavior and reward them with real tokens, including Conflux ecosystem tokens.
During walks, users are also educated about blockchain and how it works, making Tubbly not just fun but also useful. We combine movement, learning, and rewards, turning physical activity into a gateway to Web3. This unique approach gives Conflux exposure to an untapped, everyday audience.

Our first smart contract in Conflux integreted with Tubbly app:

Users can see it in action by opening Tubbly and collecting a spot on the map, which triggers a transaction on Conflux.

In one day we onboarder 400+ users to Conflux, they generated 3,000 tx.

Alignment of the project with the Conflux Network
Tubbly can serve as a powerful Web2-to-Web3 onboarding tool tailored for the Conflux ecosystem. Through a gamified M2E experience, users are rewarded with tokens for walking and collecting them on a real-world map, each action triggering an on-chain transaction on Conflux.
By integrating Conflux-native tokens into our reward system and building directly on Conflux eSpace, we generate thousands of real user wallets, transactions, and smart contract interactions. Additionally, we offer co-branded promotional campaigns with ecosystem projects to drive awareness and incentivize user engagement.

Projects within the Conflux ecosystem will also be able to launch airdrops directly inside Tubbly, gaining exposure to over 100k users, a number that continues to grow by 300+ new users daily.
This creates a strong incentive for other builders to launch on Conflux, knowing they can tap into an already-active, gamified distribution layer (Tubbly) with proven traction, real-world utility, and cross-promotion opportunities.

Demonstrate a competitive edge that differentiates it from other projects

What sets us apart:

  • Gamified real-world interaction: users collect tokens by physically walking and interacting with a live map, not just clicking buttons or performing on-chain tasks.
  • Built-in distribution channel: with over 100,000 users and 300+ new users daily, we offer an immediate, scalable user acquisition layer for Conflux and its ecosystem projects.
  • Airdrop engine for partner projects: ecosystem tokens can be distributed through quests or map drops in-app, giving Conflux-based projects a unique marketing channel with high visibility and measurable results.
    Tubbly isn’t just another dApp, it’s a movement platform that rewards healthy behavior, drives daily user engagement, and brings new audiences into Web3 ecosystems like Conflux.

Technical Introduction
The proposed system aims to provide a scalable and engaging onboarding solution for the Conflux blockchain by integrating it with a gamified Move-to-Earn mobile application. The core idea is to turn physical activity, specifically walking - into a way to earn tokens and interact with blockchain technology, lowering the barrier for Web2 users to enter the Web3 space.
Most existing solutions focus on speculative models or complex DeFi tools that are not appealing or accessible to the average user. There is a clear gap in the market for simple, fun, and reward-driven mechanisms that introduce users to on-chain activity without requiring prior technical knowledge.
This system is being developed to address that gap. Its purpose is to connect real-world actions (steps, movement) with meaningful blockchain interactions such as token rewards, wallet creation, and smart contract-based airdrops. It also provides ecosystem projects with new tools to reach and engage users through location-based campaigns and reward mechanisms.
The scope includes native Conflux wallet support in-app, smart contract deployment for token distribution, an Airdrop Mode for Conflux ecosystem projects, and payment integration with CFX tokens. The system will also support analytics and campaign tracking to provide partners with measurable outcomes.
The success of this project will be evaluated by key metrics such as user growth, number of Conflux wallets created , total on-chain transactions generated, and the number of ecosystem partners onboarded. This system has the potential to become a long-term gateway for onboarding new users into the Conflux ecosystem through practical, real-world utility and engaging mobile experiences.

Technical Proposal
As part of the planned Conflux integration, the system will support native wallet functionality, token reward mechanics, and promotional airdrops directly within the mobile app. Users will be able to connect or create Conflux-compatible wallets, collect tokens by walking to real-world locations, and redeem them for in-app rewards using CFX or ecosystem tokens. Partner projects will have access to a built-in “Airdrop Mode” that allows them to distribute tokens to users through location-based quests.
Key elements of the system include a backend engine that handles user steps, wallet logic, token distribution, and real-time syncing with the Conflux blockchain. The mobile app will provide a live map interface, quest progress tracking, and a smooth user experience for interacting with tokens. Smart contracts deployed on Conflux will manage airdrops and reward logic, while the frontend will support a dedicated interface for users to explore partner campaigns and claim tokens.
Non-functional aspects of the system are also prioritized. It will be designed for scalability, supporting thousands of concurrent users and up to hundreds of thousands of on-chain transactions per month. The user interface will remain lightweight and intuitive, with minimal friction between registering, walking, and receiving tokens. Notifications and campaign banners will promote ecosystem tokens in-app, driving both visibility and on-chain activity.

Dear Tubbly Team,

Thank you for submitting your proposal - it’s great to see the strong early traction and your focus on onboarding Web2 users into the Conflux ecosystem through real-world activity.

Before we proceed with evaluation, we’d appreciate your input on a few points to better understand the project’s structure and long-term potential:

  1. Incentive Sustainability
    • What’s the long-term plan to sustain token rewards after the grant?
    • Will you introduce a native token, or rely fully on ecosystem partnerships?
  2. User Retention
    • Could you share some insight into user retention - how many users stay active over time?
  3. Airdrop Mode
    • How do you plan to prevent farming or GPS spoofing?
    • Can ecosystem projects customize how tokens are distributed (e.g. distance, time, limits)?

We’re excited about the potential here and appreciate your efforts in bridging everyday activity with Web3. Looking forward to your reply.

Best,

Máté

@Mate_Conflux, thank you.

1. Incentive Sustainability
• What’s the long-term plan to sustain token rewards after the grant?

We will conduct airdrops occasionally (during Conflux events). We also want to offer rewards in a hybrid model - e.g., 80% in Tubbly tokens (they’re not on-chain yet, but we plan to launch them soon) and 20% in CFX tokens. This way, users will have to collect both types of tokens. Such cooperation can continue after the grant ends, which benefits both Tubbly users (token variety) and Conflux (usage of CFX as a payment token).

We have partnerships with affiliate networks, including brands like Samsung and Aliexpress. We also onboard new companies every week from around the world that distribute their products through Tubbly (as prizes for players).

• Will you introduce a native token, or rely fully on ecosystem partnerships?

We plan to launch a token (TUBE token) in the future, but after we reach over one million users. The token will be released mainly for marketing purposes, to create buzz around Tubbly in web3.

2. User Retention
• Could you share some insight into user retention - how many users stay active over time?


Retention in Tubbly is above the 75th percentile across all categories:
– Day 1: 52.78% (vs ~37.06% in the top 25%)
– Day 7: 27.78% (vs ~18.68%)
– Day 28: 14.44% (vs ~11.37%)

This means Tubbly retains users better than most Health & Fitness apps on the App Store.

3. Airdrop Mode
• How do you plan to prevent farming or GPS spoofing?

We are implementing a stepcounting system that will soon be available for players, we already see how many steps users take. This gives us a good indication of whether users are actually walking. Additionally, we have a GPS position monitoring mechanism (without saving the data), which detects extreme cases (e.g., teleporting between locations).

Both systems complement each other well and help detect potential cheaters.

• Can ecosystem projects customize how tokens are distributed (e.g., distance, time, limits)?

Yes, ecosystem projects can define:
– the duration of the airdrop,
– the walking time required to claim tokens,
– the minimum/maximum distance,
– the daily limits per user (e.g. a maximum of 5 spots with a set number of tokens to collect).

If you have more questions, we’re happy to answer!

Best,
Maurycy

Tubbly users just hit 100,000 transactions! It’s easy to see how it works, every time a user claims tokens on the Tubbly map, a transaction appears on Conflux and updates their account balance.
