Quick Breakdown
- Mantle transitions to Ethereum blobs, moving closer to a full ZK rollup architecture for enhanced security.
- Partnership with EigenLayer continues, supporting AI, prediction markets, and perpetual trading on-chain.
- Upgrade leverages Ethereum’s Fusaka improvements, offering low-latency, low-fee, and verifiable data for dApps.
Mantle has announced a major infrastructure upgrade, shifting its network to use Ethereum blobs as its primary data availability layer, bringing the protocol closer to a full Ethereum ZK rollup architecture. The transition follows Ethereum’s recent Fusaka upgrade and further aligns Mantle with Ethereum’s long-term scaling roadmap.
The Dubai-based project said the change strengthens security guarantees while preserving the low fees and fast transaction speeds that have defined the network so far. By anchoring more of its infrastructure directly to Ethereum, Mantle is positioning itself as a more Ethereum-native Layer 2 as competition among rollups intensifies.
We believe in somETHing.
Today, Mantle is upgrading to @ethereum blobs as our primary data availability layer, signifying a major step toward becoming a full Ethereum ZK rollup.

From Validium to Ethereum-secured ZK rollup
The upgrade marks Mantle’s evolution away from a Validium-style setup toward a ZK rollup model secured by Ethereum’s base layer. With rollup data now posted to Ethereum blobs, transaction data becomes fully available and verifiable on Ethereum, reducing reliance on external trust assumptions.
Ethereum blobs, introduced as part of Ethereum’s modular scaling approach, significantly expand data throughput at lower cost. Mantle said this allows it to inherit stronger security properties from Ethereum while maintaining performance suitable for production-scale applications, including decentralized finance and real-world asset platforms operating on-chain.
Retaining EigenLayer ties while deepening Ethereum alignment
Despite the shift to Ethereum blobs for core data availability, Mantle will continue working closely with EigenLayer and its broader ecosystem. The network plans to use EigenLayer-based infrastructure for specialized workloads where verifiable compute and restaked security are critical, including perpetuals trading, prediction markets, AI agent infrastructure, and shared security initiatives.
Mantle said the transition highlights how Layer 2 networks can dynamically adopt Ethereum’s base-layer improvements without abandoning modular partnerships. The project views this hybrid approach as essential to supporting institutional use cases, real-world asset issuance, and large-scale decentralized applications.
In another development, Mantle teamed up with Bybit and CIAN to launch the Bybit Mantle Vault, a native on-chain stablecoin yield product designed to simplify DeFi participation.
