At Mantle, we believe that continuous innovation is essential to driving the future of decentralized finance (DeFi) and creating a thriving ecosystem for builders and users. With this vision in mind, we are excited to announce our strategic integration with Succinct’s SP1 — marking a significant milestone in our technical roadmap as we transition to a zero-knowledge (ZK) validity rollup. This transition underscores Mantle’s commitment to delivering cutting-edge scalability, institutional-grade security, and capital efficiency for the future of on-chain finance.

Advancing Institutional Asset Settlements with ZK Rollup Technology

Mantle’s adoption of Succinct’s SP1 represents a pivotal shift from our current optimistic rollup model to a ZK validity rollup. This upgrade significantly enhances the network’s capabilities, achieving chain finality within one hour — a 168x improvement over existing bridging capabilities.

With secure 1-hour withdrawals, Mantle Network positions itself much closer to Ethereum L1 economically, enabling better swap market spreads, lower slippage, better money markets, improve interest rates and broader asset availability.

By integrating its modular architecture, EigenDA-powered data availability solution, and ZK proofs via SP1, Mantle Network is paving the way for a liquidity chain designed for institutional-grade settlement and value transfer within the crypto ecosystem.

Why Succinct’s SP1?

The strategic integration of Succinct’s SP1 offers a suite of advanced features catered to developers and users:

• Fast Finality: Transactions are finalized in just one hour, enabling seamless withdrawals and improving user experience.
• EVM Equivalence: Full Ethereum Virtual Machine (EVM) bytecode compatibility ensures developers can deploy existing smart contracts and tools without modifications.
• Cost Efficiency: Integrated prover fees reduce operational costs for rollup teams and minimize transaction costs for users, keeping fees as low as fractions of a cent.
• Multi-Chain Future: By aligning with Ethereum’s security ethos, SP1 supports cross-rollup interoperability, paving the way for interconnected ecosystems.

Enabling Next-Generation dApps

The integration of SP1 goes beyond improving technical metrics — it lays the foundation for a more cohesive and interconnected Ethereum ecosystem. Developers building on Mantle can leverage the modularity and cryptographic trust of ZK rollups while benefiting from the accessibility of Ethereum-standard compatible tools.

We're enabling frontier UX developments by adopting validity proofs — all our on-chain actions are cryptographically verified to be correct. This higher tier of security allows us to more easily and safely explore areas that enhance the L2 experience.

By seamlessly combining user-friendly optimistic rollups with advanced ZK technology, Mantle Network reinforces its role as an environment driving innovation across DeFi, gaming, and other verticals, and further supports the development of next-generation decentralized applications (dApps).

"In my previous banking career, I witnessed traditional banking infrastructure and legacy banking business models struggle to keep up with the emergence of FinTech disruptors built with cloud services that boast cost advantages with operational efficiency. The introduction of programmable blockchains along with stablecoins heralds the next natural step in disruption of financial services – being even more operationally efficient and resilient. The integration of Succinct’s SP1 marks a defining chapter in Mantle Network’s strategic blockchain journey to support banking for the next generation. By uniting zero-knowledge proofs with the proven versatility of the OP Stack, we’re not just evolving as a Layer-2 solution — we’re setting a new benchmark for institutional-grade Ethereum scalability that enables highly efficient and unparalleled security for high-value transactions at the cost of a few cents with 24/7 settlements" said Joshua Cheong, Product Lead at Mantle.

Driving Ethereum’s Future

Mantle Network’s evolution with Succinct’s SP1 strengthens its alignment with Ethereum’s decentralized security model and scalability goals. By transitioning to a ZK validity rollup, Mantle reinforces its role as an ETH-aligned Layer 2, fostering a more interconnected ecosystem with seamless flows of assets and information, thereby reducing fragmentation across networks.

Uma Roy, CEO and Co-Founder at Succinct adds, “Succinct’s SP1 empowers any developer to make ZK applications by just writing Rust, accelerating the adoption of ZK and verifiable computation. With OP Succinct, we can propel any OP Stack rollup into the future by providing fast finality with no downsides. By merging SP1’s blazing-fast performance with Mantle’s progressive vision, we’re enabling developers to reimagine decentralized applications with unprecedented speed, efficiency, and reliability. Together, we’re building the foundation for Ethereum’s interconnected and scalable future.”

Ready to Build the Future?

With the testnet launch in Q1 2025 with intention towards mainnet upgrade, we are starting 2025 on the right note, furthering Mantle Network’s strategic blockchain journey to support next-generation banking.
