TLDR

Arkham to drop Linea, Manta, and Blast L2s from its platform starting January 11.

Decision follows Arkham’s routine chain review focused on user activity and relevance.

Arbitrum, Optimism, Base, Mantle, and Polygon zkEVM remain supported by Arkham.

Linea faced issues in 2025 but stabilized before its token airdrop launch.

Arkham Intelligence will stop supporting the Linea, Blast, and Manta Layer-2 networks on its intelligence platform. The removal will take effect on January 11, 2026, as part of Arkham’s periodic review of chain integrations.

According to Arkham’s official statement, chains are assessed based on factors such as user demand, platform relevance, and their broader role in the crypto ecosystem. The company posted the update on its X page on January 9, noting that Linea had not met its criteria during the most recent evaluation.

While the specific reasons were not shared, users speculated that the lack of on-chain activity and lower adoption rates could be key factors. There has been no record of such removals in 2025, suggesting a new trend by Arkham to streamline its offerings.

Linea to Be Removed Alongside Manta and Blast

Linea, an Ethereum Layer-2 developed by Consensys, will be among the chains removed from Arkham. The blockchain had seen earlier traction but may have failed to maintain ongoing relevance.

Arkham confirmed that Blast and Manta would also be removed from its platform on the same day. These announcements were shared across the company’s social channels within days of each other. Users raised concerns about reduced transparency and the inability to track token flows without Arkham’s monitoring tools.

As of now, no further chains have been confirmed for removal, though Arkham may continue this review process as the year progresses.

Remaining L2s on Arkham’s Platform

Despite the removal of three L2s, several major Ethereum scaling networks continue to be supported on Arkham. These include Arbitrum, Base, Optimism, Mantle, and Polygon zkEVM.

All of these networks have maintained high user engagement, particularly after Ethereum’s 2024 Dencun upgrade, which helped offload transaction data from the mainnet to Layer-2s. This shift made many L2s more efficient and useful for scaling Ethereum transactions.

According to Arkham’s current platform data, these L2s consistently generate enough usage to warrant continued support. This suggests that Arkham is prioritizing performance and utility over chain diversity.

Ethereum Upgrades and Layer-2 Network Trends

Ethereum’s Dencun upgrade in 2024 introduced protodanksharding, which allowed L2s to store data in separate blob space. This reduced the data competition on the Ethereum mainnet and improved Layer-2 efficiency.

Later upgrades, including Pectra and Fusaka in 2025, increased the blob capacity, further optimizing the network. As CoinCentral reported, these changes helped maintain activity across major L2s. The upcoming Glasterdam upgrade in 2026 is expected to expand blob handling even further.

These developments have helped the supported L2s continue growing, which may explain their retention on Arkham’s platform. Meanwhile, networks like Linea, Manta, and Blast may not have achieved comparable adoption.

As CoinCentral detailed, Linea had previously resolved a sequencer issue in 2025 just before its token airdrop. Although the problem was fixed quickly, it did not appear to change the network’s long-term usage trajectory.
