1Self.World uses blockchain to solve long-standing problems in digital advertising. With user-friendly services, we return ad data monopolized by large platforms to users, building a fair, transparent ecosystem.
Our proprietary Web3.0 ID (W3ID) merges blockchain wallets and ad attributes for precise, efficient targeting. In Korea, our POC ‘MyB’ achieved over three times the industry-average ARPDAU (USD 2.5).
Building on this, 1Self.World will deliver W3ID through AdChain, supplying media partners to spread W3ID and position it as an ad identifier for the cookieless era. We aim to surpass existing identifiers and become a new standard in global marketing.
