Event date

Wednesday 16 July 2025, UTC

Event description

The v1.3.0 upgrade, scheduled for 7 AM UTC, brings full compatibility with Ethereum’s Prague upgrade, enhancing scalability, efficiency, and user experience on Mantle’s testnet. This includes support for advanced Ethereum Virtual Machine (EVM) improvements and wallet functionalities, as outlined in CoinGecko’s 2024 analysis of the Pectra upgrade (Prague/Electra merger) [CoinGecko, 2024-06-28]. For developers and node operators, this opens doors to build cutting-edge decentralized apps (dApps) with smoother transactions. The upgrade involves a brief 5-minute node interruption, with a firm deadline to complete by July 16 to avoid downtime [Mantle Devs, 2025-07-08]. While exciting, users should note the non-supported downgrade post-upgrade as a minor risk to plan accordingly.

Recent News

Mantle has been on a roll! In mid-2023, the network launched its Mainnet Alpha, followed by the v2 Testnet Sepolia in July 2023, introducing native token migration and meta-transactions for gas-free interactions [mantle.xyz, 2023]. More recently, the project’s ecosystem has grown, boasting 83 core projects on testnet, including integrations with The Graph and Pyth [mantle.xyz, 2025]. This upgrade builds on that momentum, reinforcing Mantle’s position as Ethereum’s largest L2 with zero-knowledge proofs.

Future Plans

Looking ahead, Mantle aims to unveil its Mainnet fully within the next quarter, per their 2025 roadmap [mantle.xyz, 2025]. This includes expanding its "Liquidity Chain" vision with modular architecture and data availability solutions. The team also plans iterative improvements based on community feedback from the v1.3.0 testnet, hinting at a community-driven approach to future releases.

Onchain Data

Specific onchain metrics for the upcoming upgrade aren’t yet available as of July 13, 2025, given its proximity. However, Mantle’s v2 Testnet has shown robust activity, with growing transaction volumes tied to its 83 dApps. Post-Pectra upgrade, Ethereum’s transaction volume surged 15% in July 2025 [Etherscan, 2025], a trend Mantle is poised to capitalize on as an L2.

Community Sentiment

X reactions are buzzing with excitement! Users like @0xeliska and @ivan_wang_0326 have cheered the upgrade, praising Mantle’s innovative edge [X, 2025-07-10]. Influencers highlight the project’s user experience (UX) superiority over competitors [X, 2025-07-08], though some caution about the brief downtime. Overall, sentiment leans positive, reflecting confidence in Mantle’s growth.

Additional Insights

This upgrade aligns with a 40% ETH price surge since the Pectra upgrade [CoinMarketCap, 2025], suggesting a bullish market for Ethereum-based L2s like Mantle. Competitors like Arbitrum and Optimism may feel pressure to match these advancements, giving Mantle a temporary edge. For users, expect easier dApp interactions and potential airdrop opportunities as the ecosystem expands.

Risk Disclaimer: As with any upgrade, minor technical hiccups or market volatility could occur. Always research and proceed cautiously.
