User Experience: Faster, Simpler, More Secure
Linea’s user experience initiatives are designed to eliminate friction, reduce costs, and enhance security for everyday users and advanced participants alike.
Q1 2025 Highlights
- ERC-20 Gas Token Support
Users will soon pay gas fees using any ERC-20 token—including stablecoins or the native LINEA token—without needing ETH in their wallet. Leveragingeth_sendBundle, this feature enables private transaction routing directly to the sequencer. MetaMask has confirmed Day 1 integration, allowing MetaMask Card users to onboard seamlessly using familiar assets. - Linea Bridge UI V2
A redesigned bridging interface will integrate third-party solutions like Across, enabling faster and more flexible cross-chain transfers from multiple L1s and L2s into Linea—surpassing limitations of the native bridge. - Private Transaction Pool
Combat front-running and malicious MEV with a permissioned private transaction endpoint (eth_sendBundle). Transactions bypass the public mempool, protecting users and protocols such as ERC-4337 account abstraction systems. Initial gas pricing mirrors public rates for fairness. - Removal of Finalization Delay
The 6-hour SNARK proof submission delay—originally a safety "training wheel"—will be removed. Now that the system is mature, proofs will be submitted immediately upon generation, accelerating finality. - Auto-Claiming L1 → L2 Messages
Through the “Postman” mechanism, ERC-20 deposits from Ethereum to Linea will auto-claim upon confirmation. No additional user action is required, simplifying onboarding and reducing friction.
Q2 2025
- Lower L1 Cost via Pectra Fork Integration
By adopting BLS12-381 precompiles from Ethereum’s upcoming Pectra upgrade, Linea will enable efficient KZG batching and signature aggregation for blob data. This optimization reduces on-chain data publishing costs by up to 60%, directly lowering transaction fees.
H2 2025 Advancements
- 1-Second Block Time
Block intervals will shrink from 2s to 1s, doubling throughput and improving responsiveness. Made possible by the “limitless prover,” this change maintains balance with ongoing sequencer decentralization efforts. - Reduced Proof Time (~3 Minutes)
Vortex proof generation latency will drop from ~12 minutes to ~3 minutes through smaller elliptic curve fields (e.g., moving away from BLS12-377), speeding up finality and reducing user wait times. - Account Abstraction in Sequencer
Native integration of ERC-4337 into the sequencer eliminates reliance on external bundlers. User operations (UserOps) are processed directly by the block builder, enabling advanced wallet capabilities like session keys and self-custodial recovery. - Native Yield (Status L2 Only)
ETH deposits will earn yield via staking derivatives—but only on Status L2. This feature remains behind a flag and is not enabled for Linea Mainnet.
2026 Milestones
- 0.5s Block Time
Block production will halve again to 500ms, dramatically increasing speed while maintaining security amid decentralized sequencer distribution. - Fast Withdrawals
Users can opt to pay a premium for expedited SNARK proof submission when exiting to Ethereum—ideal for time-sensitive transactions. This complements existing third-party bridges. - Enhanced MEV Handling
Research into fairer MEV distribution models continues, aligned with Ethereum’s evolving standards to protect users and validators.
2027 and Beyond
- 0.25s Block Time ("North Star")
A visionary target enabling ultra-low-latency applications like high-frequency trading and real-time gaming. Success depends on breakthroughs in proof systems, consensus design, and client performance.
Developer Experience: Unleashing Scalability
For developers building dApps, DeFi protocols, and Web3 tools, Linea delivers high performance, predictable costs, and future-proof compatibility.
Q1–Q2 2025
- Increased Gas Throughput (22.5 mGas/s → 27.5 mGas/s)
Execution capacity in Besu rises from 15 mGas/s to 27.5 mGas/s within two quarters—supporting over 100 TPS initially—with continued growth enabled by architectural improvements. - Limitless Prover Launch
Replaces rigid EVM operation limits (~50 steps) with a single computational constraint. This slashes sequencer overhead, boosts transaction density per block, and reduces memory needs for proof generation.
👉 See how high-throughput blockchains are redefining developer possibilities.
H2 2025
- Block Throughput: 0.5 gGas/s
A major leap toward mass scalability, powered by the limitless prover and client optimizations. - Pectra EVM Upgrade
Linea upgrades from London to Pectra (Paris + Shanghai + Cancun), bringing full access to modern EVM features including EIP-7702 for enhanced EOA functionality. - Keystore Wallets MVP
Early development begins on cross-chain compatible account abstraction wallets in collaboration with MetaMask and other leaders. - Guaranteed Price Pilot
Certain dApps (e.g., MetaMask Card) receive predictable fee structures decoupled from L1 congestion—ideal for consumer-facing applications.
2026 Goals
- 1 gGas/s Throughput (~10,000 TPS)
Scales to meet growing demand across DeFi, NFTs, and social applications. - Continuous EVM Upgrades
Ensures alignment with all future Ethereum hard forks and protocol enhancements.
2027+
- Multi-Client Support at 2 gGas/s (~20,000 TPS)
Achieves extreme scale with diverse client implementations for resilience and security. - Type 1 zkEVM Evolution
As Ethereum adopts Verkle Trees and zk-friendly state representations, Linea may transition to a Type 1 zkEVM—minimizing divergence from L1 logic and paving the way for native rollup integration at the protocol level.
Community Experience: Decentralization & Trust
True decentralization requires transparency, verifiability, and community governance—pillars embedded in Linea’s long-term design.
Q1–H2 2025
- Prover Completeness (Alpha → Beta)
Full coverage of London EVM execution removes the "recategorization timer" on L2Beat—signaling maturity in proof integrity. - State Reconstruction
Anyone can rebuild Linea’s state entirely from L1 data in case of failure—ensuring fund safety even under catastrophic node loss. - Security Council (LSC)
A 9-of-12 Gnosis Safe multisig governs critical upgrades with a default 7-day timelock, giving users time to exit if needed. Overrides allowed only for urgent security fixes. - Consensus Transition: Clique → QBFT (Maru)
Moves from a single-authority model to Quorum Byzantine Fault Tolerance (QBFT), supporting Ethereum Engine APIs and laying groundwork for decentralization. - Permissioned DPoS Launch
Validators are selected from a trusted set using QBFT consensus—an intermediate step toward full decentralization. - Formal Verification Begins
Critical EVM logic up to Pectra undergoes rigorous mathematical verification to prevent bugs and exploits. - Stage 1 Escape Hatch
Users retain the ability to exit safely during operator failure or censorship—ensuring trustless access. - Stage 2 Upgrades
Includes a 30-day timelock for major changes, multi-prover models combining TEE and PoS validation, and extended finality delays when consensus is incomplete.
2026–2027+
- Permissionless DPoS
Opens validator participation to anyone willing to stake. Random subcommittee rotation and slashing enforce accountability. - zkVM Multi-Prover System
Integrates alternative zkVMs (e.g., RISC-V) into a diversified proof-generation framework for improved performance and attack resistance. - Ongoing Formal Verification
Every EVM or protocol update undergoes formal analysis to maintain ironclad security guarantees.
Additional Focus Areas
Linea actively contributes to Ethereum-wide proposals shaping the future of Layer 2 interoperability:
- EIP-7667: Adjusting hash function gas costs
- EIP-7759: Standardizing L2 transaction fee models
- ERC Cross-Chain Standards (7785, 7828, etc.): Defining chain addresses, intents, and token interfaces
- RIP-7755: Enabling cross-chain call protocols
The team is also exploring Linea’s role as a “based rollup” and contributing to FABRIC, an initiative aimed at seamless L1-L2 integration. Insights from these efforts may inform future roadmap updates.
