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.

Questions & Answers

As answered by people managing ViewFi and Outbrain.

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.

・Users are rewarded, not exploited

・Publishers gain a new revenue layer without harming UX

・Advertisers 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:

・Web3 apps and DApps

・Wallets and DeFi platforms

・Event platforms and communities

・Brands 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 repeat—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:

・Blockchain and smart contracts (for reward logic and transparency)

・On-chain and off-chain data analysis

・Web-based SDK architecture for easy integration

・Secure 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.
