South Korean electronics manufacturer LG Electronics is developing a blockchain-powered advertising infrastructure in partnership with Arbitrum, a layer-2 scaling solution for the Ethereum network.
According to the company, it has created a proprietary layer-2 blockchain infrastructure working alongside Arbitrum, enabling rapid, cost-effective transactions on Ethereum’s network.
The initiative seeks to provide both advertisers and content publishers with a unified, transparent ledger for ad inventory management while monitoring consumer interaction with advertisements.
The Case for Blockchain in Digital Advertising
Conventional digital advertising operations depend heavily on third-party platforms that facilitate and automate ad space transactions. These intermediary services increase operational expenses while diminishing transparency for all parties involved.
Blockchain technology offers an alternative by eliminating these middlemen. The distributed ledger approach enables automated ad transactions through smart contracts without requiring human oversight.
“You don’t need manual interventions,” Arbitrum co-founder Steven Goldfeder told Fortune. “You can basically run the market in an automated way in software.”
LG revealed it conducted a pilot program with a Japanese advertising partner through its specialized blockchain innovation division. The electronics giant is currently assessing the platform’s commercial viability for a potential late 2026 market entry.
Global digital advertising expenditure reached approximately $679 billion in 2025, representing 68% of all advertising investment worldwide, based on data from international advertising corporation Dentsu.
LG’s Track Record in Blockchain Technology
The advertising platform marks another chapter in LG’s ongoing blockchain exploration, which spans nearly ten years.
Back in 2018, LG CNS introduced Monachain, an enterprise-focused blockchain designed for various commercial applications including payment processing, digital identity verification, and logistics tracking.
Four years later, in 2022, LG Electronics released Wallypto, a cryptocurrency wallet developed on the Hedera Hashgraph infrastructure, supporting its NFT marketplace called LG Art Lab. This platform enabled customers to showcase digital artwork on their television screens.
Both LG Art Lab and Wallypto were discontinued in 2025, closing in June and September respectively.
The latest advertising initiative signals a strategic pivot from consumer-oriented cryptocurrency offerings toward business-focused blockchain solutions.
Industry Response
Following the partnership revelation, Arbitrum’s native ARB token climbed over 7% to $0.0834 within 24 hours. The overall cryptocurrency sector experienced upward movement as well, with Bitcoin advancing more than 3% to $63,500.
Samuel Byungsun Park, who leads LG’s blockchain research division, stated the company is determining whether this technological approach can “deliver meaningful value to advertisers, publishers and audiences.”
While no specific launch timeline has been announced, LG has suggested the platform might become available before 2026 concludes.
