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.

  • 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.

Analysis of MoPub

Overall verdict

  • As of the current date, MoPub is not a viable option since it is no longer operational. Publishers looking for similar solutions need to explore alternative platforms.

Why this product is good

  • MoPub was a popular mobile ad exchange platform known for its comprehensive monetization and mediation features. It offered tools for publishers to optimize their ad revenue with real-time bidding and a wide array of demand partners. However, as of early 2022, MoPub ceased operations following its acquisition by AppLovin Corporation, rendering it unavailable for new users.

Recommended for

    Previously, MoPub was recommended for mobile app publishers seeking a robust ad exchange platform with strong monetization potential. Since its closure, these users may now consider alternatives like Google AdMob, Unity Ads, or AppLovin MAX.

  • No independent reviews or reputable sources are available to me for this specific product
  • Making claims about an unfamiliar service could be misleading or inaccurate
  • I recommend checking the website directly, looking for verified user reviews on trusted platforms, and checking domain registration/reputation tools before trusting this service

Questions & Answers

As answered by people managing MoPub and ViewFi.

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.

How would you describe the primary audience of your product?

ViewFi's answer:

The primary audience of ViewFi includes:

ใƒปWeb3 apps and DApps

ใƒปWallets and DeFi platforms

ใƒปEvent platforms and communities

ใƒปBrands and advertisers targeting verified Web3 users

In short, ViewFi is built for teams that want engagement they can prove, not just traffic they can buy.

What's the story behind your product?

ViewFi's answer:

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.

Which are the primary technologies used for building your product?

ViewFi's answer:

ViewFi is built using a combination of:

ใƒปBlockchain and smart contracts (for reward logic and transparency)

ใƒปOn-chain and off-chain data analysis

ใƒปWeb-based SDK architecture for easy integration

ใƒปSecure attribution and conversion tracking systems

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:

ViewFi works with a mix of Web3 platforms, event ecosystems, and advertiser partners across multiple regions.

Rather than focusing on brand names alone, ViewFi prioritizes partners who value measurable engagement and fair user rewards, and many pilots are conducted with global Web3 events and growing DApp ecosystems.
