ViewFi SDK is a rewarded advertising SDK designed to transform advertising from an interruption into a value exchange.

Instead of forcing ads into the user experience, ViewFi allows users to opt in to watching ads and receive clear rewards in return. This changes how users perceive advertising, from something they tolerate to something they actively choose.

For publishers and app developers, ViewFi SDK enables monetization without sacrificing user experience. Ads are shown only when users are willing to engage, resulting in higher attention, longer watch time, and more meaningful interactions. This leads to improved retention, reduced churn, and sustainable revenue growth.

For advertisers, ViewFi SDK provides access to highly engaged audiences. Because users choose to watch ads, attention quality is significantly higher than traditional interruptive formats. ViewFi supports measurable outcomes beyond impressions, including completed views, engagement actions, and post-ad behavior. Campaigns are not just seen, they are experienced.

ViewFi SDK is built for seamless integration across apps, services, and platforms. With flexible placement options and minimal development effort, teams can deploy rewarded ad experiences without disrupting existing UX flows. Reward structures are customizable, allowing alignment with product logic and user journeys.

A key strength of ViewFi SDK is incentive alignment. Users receive fair value for their attention, publishers unlock new monetization channels without alienating their audience, and advertisers gain transparency, performance, and trust.

Unlike traditional ad SDKs that focus on volume, ViewFi emphasizes attention quality. Every interaction is intentional, permission-based, and measurable, making ViewFi ideal for environments where trust, retention, and long-term engagement matter.

ViewFi SDK is not just an ad SDK. It is a framework for building fair, engaging, and sustainable advertising experiences.

ViewFi features and specs

  • ViewFi WhiteLabel SDK
    The White-Label SDK is designed for partners who want to fully control the branding of the integration โ€” meaning partners can rebrand the SDK with their own logos, colors, and styling.
  • Cross-Platform SDK Integration
    ViewFi SDK supports iOS, Android, and Web environments, and can be integrated into major frameworks such as React Native, Flutter, and Unity. A single SDK enables rapid deployment across multiple platforms with minimal development effort.
  • Real-Time Event & Conversion Tracking
    The SDK tracks user actions such as ad views, clicks, content interactions, and transactions in real time. All events are recorded and reflected instantly, enabling accurate measurement and optimization.
  • Modular Ad & Reward Engine
    ViewFi SDK includes a built-in ad player and reward engine, allowing rewards to be issued based on predefined user actions. Publishers can easily implement rewarded experiences without building custom logic from scratch.
  • Publisher-Controlled Mission System
    Media and apps integrating the ViewFi SDK can create and manage custom missions for users. Publishers can define mission conditions, rewards, and timingโ€”turning their own user actions into structured, rewardable missions.

Level Devil features and specs

  • Simple and Addictive Gameplay
    Level Devil features straightforward platformer mechanics that are easy to pick up but hard to master, making it highly addictive for players of all skill levels.
  • Unpredictable Challenges
    The game constantly surprises players with unexpected traps, shifting floors, and moving obstacles that keep the gameplay fresh and exciting throughout each level.
  • Free to Play
    Level Devil is accessible as a free browser-based game, meaning anyone can play it without needing to download software or pay for access.
  • Minimalist Design
    The clean, minimalist art style and simple controls make the game visually appealing and easy to understand without cluttered interfaces or overwhelming graphics.
  • High Replayability
    The difficulty and unpredictable nature of the traps encourage players to replay levels multiple times, providing a satisfying sense of accomplishment when finally completing a tough stage.

Possible disadvantages of Level Devil

  • Extremely Frustrating Difficulty
    The game's reliance on surprise traps and sudden deaths can feel unfair, leading to significant frustration especially for players who prefer skill-based challenges over trial-and-error gameplay.
  • Repetitive Mechanics
    Despite the surprise elements, the core gameplay loop of running, jumping, and dodging traps can become repetitive over extended play sessions with limited variety in mechanics.
  • Limited Content Depth
    As a simple browser game, Level Devil lacks the depth of a full platformer โ€” there are no storylines, character progression, or complex level design elements to keep players engaged long-term.
  • Trial-and-Error Design
    Many traps are nearly impossible to avoid on a first attempt, meaning success often depends on memorization rather than genuine skill, which can feel cheap and unsatisfying.
  • No Save or Progress System
    The game may lack robust save or checkpoint systems, meaning players can lose significant progress and have to redo sections they have already completed, adding to the frustration factor.

Questions & Answers

As answered by people managing ViewFi and Level Devil.

What makes your product unique?

ViewFi's answer

ViewFi is unique because it is not just an ad SDK, but a reward-based engagement infrastructure for Web3. It allows apps and platforms to reward users for verified attention and actions, while enabling advertisers to measure outcomes tied to on-chain and off-chain behavior.

Unlike traditional ad SDKs that optimize for impressions or clicks, ViewFi is designed around measurable user participation and incentive alignment.

Why should a person choose your product over its competitors?

ViewFi's answer

People choose ViewFi because it aligns incentives for users, publishers, and advertisers at the same time.

ใƒปUsers are rewarded, not exploited

ใƒปPublishers gain a new revenue layer without harming UX

ใƒปAdvertisers pay for outcomes, not just exposure

This makes ViewFi especially attractive for Web3 products that care about trust, transparency, and long-term user relationships.

ViewFi was created from a simple observation: attention is valuable, but it has never been fairly rewarded or properly measured.

The team behind ViewFi has decades of experience in digital advertising and saw the same problems repeatโ€”opaque metrics, misaligned incentives, and user fatigue. Web3 offered a chance to rebuild this system with transparency, rewards, and accountability at the core.

The design focuses on flexibility, scalability, and minimal friction for both users and developers.

Who are some of the biggest customers of your product?

ViewFi's answer
