Carbon Browser

Carbon Browser needed to acquire users who would not only download the app but also engage deeply enough to purchase $CSIX tokens, converting installs into active token holders. Four obstacles defined what that required:

• Two-step conversion funnel: The campaign needed to drive both an app install and a subsequent token purchase. Each step required a different user motivation to activate.
• Privacy-native audience: The target user actively avoids data-heavy ad platforms, making standard programmatic channels a poor fit for reaching them.
• Global scale with niche profile: Crypto-native, privacy-conscious developers exist across all markets but represent a small share of any broad audience segment.
• Token adoption barrier: Converting a browser user into a token holder required reaching users with both Web3 wallet access and prior token purchase behaviour.

Carbon Browser's target audience are the users most likely to be running ad blockers, VPNs, and privacy tools on mainstream platforms. Reaching them through Google or Meta display inventory was structurally unlikely. The campaign needed a network where audience qualification was built on verified on-chain activity, not behavioural inference from browsing history.

Blockchain-Ads provided the targeting layer the campaign required through four capabilities: 

• Active wallet segments: Campaigns reached wallets with verified Web3 participation and recent on-chain transaction history.
• High-net-worth individual targeting: Audience filters identified holders with the investment capacity to convert from download to token purchase.
• Dev tools and AI tool interest segments: Targeting layers captured privacy-focused developers and technical users already seeking advanced browsing alternatives.
• Global crypto-native inventory: Publisher coverage across Web3, DeFi, and technology content ensured placement in front of the right audience across all target markets.

• 5,460+ app downloads at a cost per download of $18.32.
• 2,171 users converted to $CSIX token holders, a 40% download-to-token conversion rate.
• Cost per token holder: $46.07.
• Impressions: 3M+ delivered globally across the 60-day campaign.
• CTR: 0.75% blended across all formats.
• Total clicks: 21,982 at a CPC of $4.55.

The objective was to identify which audience segments and creative angles drove the highest download rate. Display ads ran across crypto-native and technology publisher inventory globally. Three angles were tested: 

• The product feature angle led with "Fast, 100% Privacy, dVPN, Crypto Wallet," listing Carbon's core utilities for crypto-native users.
• For the category positioning angle, it ran "The Fastest Web3.0 Browser," targeting users familiar with Web3 but dissatisfied with existing browser options.
• The launch announcement angle used "Carbon Browser is Here," driving awareness among users who had not yet encountered the product.

The product feature angle delivered the strongest download rate from active wallet segments.

Targeting was tightened to active wallet and high-net-worth segments that showed the highest post-click engagement in Phase 1. The social proof angle was introduced with "Join Over 5M Users of Carbon," using the existing user base as a credibility signal for undecided prospects. The privacy bundle angle ran "dVPN and AdBlock for Ultimate Privacy" and "Multichain, AdBlock, 100% Privacy" against developer and AI tool user segments. On the browse-to-earn angle, "Browse to Earn, Decentralised Browser," was introduced to connect the download action directly to a financial incentive for token-minded users.

Retargeting activated against users who had clicked but not yet downloaded. The $CSIX staking angle was scaled across all active creatives via the "Stake $CSIX" CTA, directly connecting the app download to the token holding opportunity. The browse-to-earn and social proof creatives drove the highest conversion volume in the final phase. 5,460 app downloads were recorded across the full 60-day campaign at a cost per download of $18.32. Of those, 2,171 users went on to purchase $CSIX tokens, a 40% download-to-token conversion rate.
