LG Electronics is building a blockchain-based advertising platform with Arbitrum, testing whether ad inventory, sales and audience interactions can be managed on a shared ledger.
The South Korean electronics group has completed a pilot with an unnamed Japanese advertising agency. It is now considering how to bring the product to market later this year.
LG’s R&D Team Built Custom Arbitrum Layer 2
The platform was developed by LG’s internal blockchain research department and uses a custom layer-2 network built with Arbitrum technology. The chain is designed to batch transactions at low cost while giving advertisers and publishers a shared record of available ad inventory.
The platform could reduce manual reconciliation by giving advertisers and publishers one shared record. It also records how customers interact with ads, giving buyers and sellers a common view of campaign activity.
Project Targets $679B Digital Ad Market
The push lands in a digital advertising market that reached about $679 billion in 2025, equal to 68% of global ad spending, based on Dentsu estimates.
Programmatic advertising already uses software to buy and sell ad space, but the market still relies on intermediaries to manage placement, measurement and settlement. LG’s pitch is that a blockchain record could reduce some of that friction by making inventory and engagement data easier to verify across participants.
Arbitrum Confirms LG’s On-Chain Ad Pilot
Arbitrum confirmed that LG’s blockchain team, which sits inside the company’s R&D division, is piloting an on-chain advertising network on Arbitrum. The move gives the Ethereum layer-2 project another enterprise use case beyond DeFi, trading and consumer crypto apps.
For LG, the project extends earlier blockchain experiments that included its Wallypto wallet, Monachain enterprise blockchain work and the LG Art Lab NFT marketplace. LG shut down Art Lab last year, showing that the company’s Web3 work has remained selective.
Commercial Rollout Remains Under Review
The project is still an R&D pilot, not a full commercial launch. LG has not disclosed the pilot’s scale, the agency involved, expected transaction volume or launch customers.
LG and Arbitrum still need to show that shared ad records can lower costs or improve measurement enough for agencies, publishers and advertisers to change existing workflows. Until then, the platform remains an enterprise test rather than proof that advertising is ready to move on-chain.
