Company profile
researched Aug 20261Self World (μμ νμλ) is a Korea-based company building consumer-facing Web 3.0 marketing services. Its core product is MyB, a quiz-style reward app that applies the company's W3ID (Web 3.0 Identity) technology, which places a user's identity in a digital asset wallet. User preference information is encrypted and issued as Soulbound Tokens (SBTs) recorded on a blockchain; the tokens are described as unique, immutable and non-transferable, and combinations of SBTs form a W3ID persona held in the user's own wallet. The company positions W3ID as a decentralized identifier intended to address the limitations of OS-level advertising identifiers.
In September 2025 the company launched MyB ADCHAIN, an AI-based, content-centric rewarded ad network that uses W3ID targeting and machine-learning recommendation algorithms and is built on a WebView-based, modular architecture. Beyond the ad products, the company states it is developing stablecoin infrastructure and business models for the digital marketing market, including references to Korean won stablecoins, and intends to expand across the Web 3.0 ecosystem. It also operates as a top 10 validator on the XPLA mainnet.
Founding story
The company was established in June 2023.
Business model
The company operates a wallet-based marketing platform: consumers use the MyB reward app, and their encrypted preference data (SBT-based W3ID) is used for advertising targeting and ML-driven recommendations, monetized through the MyB ADCHAIN rewarded ad network serving advertiser/media clients. The company also states it is developing stablecoin infrastructure and business models for digital marketing.
Advertising-driven: rewarded advertising and offerwall participation through the MyB app and the MyB ADCHAIN ad network, with performance framed in terms of ARPDAU, CTR and CVR. The company has also received marketing grants from blockchain foundations (Wemix Foundation, XPLA Foundation).
Traction
MyB launched in May 2024 and passed 1,000,000 registered users in April 2025, at which point cumulative SBT issuance surpassed 30,000,000. The app reports a 4.8 rating on both major app stores, a power-user (smile curve) share of 25%, and ARPDAU more than four times that of comparable competitors; MyB ADCHAIN reports offerwall participation rate relative to total DAU, CTR/CVR and ARPDAU more than three times higher than comparison benchmarks.

Market position
The company describes itself as holding the largest base of active wallet users in Korea (1,000,000+) and as a global leader in SBT issuance (30,000,000+ cumulative), and as a top 10 validator on the XPLA mainnet.
The company frames its differentiation around patent-registered W3ID technology that stores identity in a user-controlled wallet as non-transferable SBTs, positioning it as an alternative to OS-based advertising identifiers, combined with the scale of its Korean wallet user base and SBT issuance, ML-based ad recommendation, and a flexible WebView/modular integration approach.
Technology
W3ID is the company's proprietary, patent-registered technology for storing user identity in a digital asset wallet. Encrypted user preference data is issued as Soulbound Tokens on-chain, forming a non-duplicable, non-transferable SBT database; aggregated SBTs produce a W3ID persona stored in the user's wallet. MyB ADCHAIN adds W3ID-based targeting and machine-learning recommendation algorithms, delivered via a WebView-based modular approach. The company runs a top 10 validator on the XPLA mainnet.
Go-to-market
Mainstream consumers in Korea using a reward app as an entry point to Web 3.0 services, and advertisers and media partners seeking targeted, rewarded advertising inventory.
Geography
Headquartered in South Korea with a primary focus on the Korean market, while stating an intent to expand across the Web 3.0 ecosystem.
