Mantle Completes Mainnet Upgrade with Succinct ZK Technology: Largest ZK Rollup by TVL

Ethereum (ETH) Layer 2 network Mantle (MNT) has achieved a groundbreaking milestone with the completion of its mainnet upgrade, seamlessly integrating Succinct's OP Succinct solution. Announced on September 16, this significant advancement positions Mantle as the largest ZK Rollup by Total Value Locked (TVL) and marks its transition from Optimistic Rollups to innovative Zero-Knowledge (ZK) Rollups—a first among Layer 2 solutions based on the OP Stack.

Succinct's OP Succinct: Redefining ZK Rollup Integration

Central to Mantle’s upgrade is the integration of Succinct’s OP Succinct solution, a cutting-edge development from the pioneering ZK technology startup. OP Succinct enables Layer 2 networks built on Optimism's (OP) OP Stack to replace traditional fraud-proof mechanisms with advanced validity-proof systems rooted in cryptographic Zero-Knowledge proofs.

By implementing this transformative technology, Mantle maintains the core flexibility of the OP Stack while unlocking enhanced security, scalability, and operational efficiency inherent to ZK Rollups. This shift redefines decentralized network function by eliminating dependency on the outdated seven-day fraud challenge period, introducing instantaneous validation of network states via cryptographic evidence.

Withdrawal Times Reduced: Faster and Safer

One of the most remarkable changes for Mantle users is the drastic reduction in withdrawal times—from the previous seven-day waiting period to an industry-leading 12-hour turnaround. This improvement optimizes capital efficiency by dramatically reducing idle capital time, particularly benefiting institutional investors and funds tied to real-world assets (RWA).

Despite the expedited withdrawal speed enabled by ZK technology, Mantle has deliberately set the 12-hour window as a security safeguard. This intentional interval allows the network to address emergencies, such as potential cyber threats, ensuring a high level of protection for user assets.

Transition Period Guidelines: What to Expect

Although the mainnet upgrade has been finalized, Mantle users will experience a transition period lasting until midnight (local time) on September 24, during which withdrawal scenarios will temporarily adhere to the traditional seven-day challenge period system. Mantle has provided clear guidance for users navigating this interim phase:

1. Withdrawals Initiated Before September 17: Transactions initiated before the upgrade will require the full seven-day wait under the old fraud-proof system.
2. Withdrawals During September 17–23: Interfaces will continue displaying the seven-day countdown, but funds will become instantly accessible after the upgrade is fully activated on September 24.
3. Withdrawals Close to Activation: Transactions initiated shortly before activation (e.g., on September 23 at 11 PM) will automatically recalculate to reflect the updated 12-hour policy. For example, a withdrawal started one hour prior will display "11 hours remaining."

Mantle has emphasized the importance of understanding these timing nuances to avoid confusion during this transitional phase.

Advancing the Vision of "The Liquidity Chain"

Mantle’s successful adoption of ZK Rollups through its partnership with Succinct represents a bold stride toward realizing its vision of "The Liquidity Chain." By leveraging Succinct's advanced ZK technology, Mantle is laying the foundation for next-generation decentralized finance (DeFi) infrastructure, paving the way for broader institutional adoption. This transformative step underscores Mantle's commitment to enhancing ecosystem liquidity and fortifying the DeFi landscape.

Succinct’s Pioneering Role in the ZK 2.0 Era

Succinct continues to emerge as a leader in reshaping the landscape of Zero-Knowledge proofs, spearheading what is referred to as the "ZK 2.0 era." By emphasizing groundbreaking methodologies like its bridgeless model powered by ZK proofs, Succinct enables seamless Layer 1 to Layer 2 integrations without relying on conventional asset bridges. From its innovative Lighter launch to its ambitious vision of creating "an internet everyone can validate," the company is driving the evolution of decentralized networks.

Conclusion

Mantle’s transition to ZK Rollups through Succinct’s technological advancements signifies a turning point in Layer 2 network capabilities, setting new benchmarks for speed, security, and scalability. This upgrade not only establishes Mantle as the largest ZK Rollup by TVL but also reinforces its commitment to driving innovation in DeFi infrastructure and institutional finance. With Succinct leading the charge into the ZK 2.0 era, the future of blockchain technology continues to evolve toward higher efficiency and accessibility.
