Linea Positions Itself as Ethereum-Aligned Layer-2
In a recent blog post, the Linea team outlined its strategy to align closely with Ethereum’s ecosystem both technically and economically. The Layer‑2 is positioned as a full zkEVM rollup, supporting EVM bytecode natively and integrating future Ethereum upgrades without requiring contract rewrites.
Linea introduced a dual-burn fee model: 20% of net transaction fees paid in ETH are burned on L1, while the remaining 80% are used to buy and burn the LINEA token. This mechanism reinforces ETH’s deflationary dynamics and ties usage-based token value accrual into LINEA’s governance model.
The tokenomics allocate 85% of the total 72 billion LINEA tokens to ecosystem incentives, including early user airdrops and a consortium-managed ecosystem fund. The remaining 15% is reserved for ConsenSys with a five-year lockup. LINEA carries no gas or governance function itself — strategic oversight is handled by the non-profit Linea Consortium, made up of Ethereum-native stewards like ENS Labs, Eigen Labs, Status, and SharpLink .
Starting in October 2025, bridged ETH on Linea will earn native staking yield through integration with Lido, allowing liquidity providers to receive mainnet rewards while using L2 capital. This yield generates a financial incentive loop that connects scaled dApps to ETH staking economics.
Linea’s premier position for ETH capital is bolstered by its consistent design philosophy: ETH as sole gas token, integrated deflation and yield mechanics, and a token launch that supports builders, governance-neutral oversight, and public goods funding.
Ether.fi Launches One‑Click Vaults for Cross‑Chain Deposits
In a recent press release by Ether.fi, the liquid restaking protocol announced the launch of one-click vault deposits powered by Enso’s widget and integrated with LayerZero and Stargate.
The upgrade enables users to deposit assets into Ether.fi’s vaults from any supported chain or position using a single transaction, eliminating manual bridging or token conversion steps.
Ether.fi, which manages over $10 billion in TVL, said the new system significantly enhances user experience by consolidating multi-step deposit flows into a simplified, one-click interaction. The integration addresses liquidity fragmentation and will likely support future growth in TVL by making staking more accessible to users with funds on varied chains.
The implementation forms part of a broader chain-abstraction effort, as Enso’s shortcut widget abstracts cross-chain complexity for developers and end users alike. Ether.fi claims this innovation reduces UX friction and supports interoperability across multiple blockchains without requiring developers to individually integrate bridging protocols.
ERC‑4337 x OSO Release Public Tooling for Userops Analysis
The ERC‑4337 core team, in collaboration with Open Source Observer (OSO) and 31 leading account abstraction contributors, has unveiled new tooling and insights from a massive data indexing effort across the Superchain. Between October 2024 and July 2025, OSO indexed over 230 million userops, helping uncover trends in smart wallet adoption and infrastructure.
OSO’s analysis revealed that just four paymasters sponsored more than 80% of userops across the ecosystem, underscoring the outsized role of a few key infrastructure providers. Notably, World Chain surpassed Base in March 2025 as the leading destination for userops, indicating shifting developer and user preferences within the Superchain network.
The working group behind the initiative included members from OP Labs, Kofi, Patterns, Chuxin Hu, and representatives from leading bundlers and paymasters. OP Labs contributed by decoding traces and logs, which were then shared as public datasets. These are now accessible here, enabling community members to independently analyze AA performance at scale.
To further support open analytics, OSO collaborated with open_labels and EAS to launch an onchain registry of labeled ERC‑4337 participants, covering over 90% of known operators like bundlers, account factories, and paymasters.
Developers and analysts can now replicate these insights using a step‑by‑step guide published by the ERC‑4337 team. The tutorial shows how to use pyOSO, a Python-based analytics library, to create custom metrics using indexed Superchain data.
Rhinestone Poll: Is Interoperability Finally Solved?
Rhinestone brought together voices from five leading Web3 teams to answer one question: Is interoperability finally solved?
The responses, while varied, reveal a shared sentiment — not quite. Each perspective highlights different pain points in today’s fragmented cross-chain landscape, even as core pieces of infrastructure mature.
Clave argued that incentives for solvers remain unsustainable: “Certain solvers are basically running as a charity to push the industry further,” he said, calling for better economic models to support the actors facilitating abstracted UX.
Barter echoed the sentiment, stating: “We needed to connect actions natively across chains. Cross-chain solvers just provide liquidity — they don’t perform routing or algorithmic logic.” Without native orchestration of cross-chain transactions, users still face fragmented experiences.
Contango emphasized the need for native cross-chain collateral use, citing the inability to borrow on Arbitrum while holding ETH collateral on mainnet as a sign that interoperability isn’t yet achieved: “Right now you have liquidity, but not interoperability.”
LI.FI added that while progress has been made, users still jump between UIs: “From a long tail perspective, you still have a non-chain-abstracted experience.” According to him, the industry is iterating on known primitives rather than inventing fundamentally new ones.
The only cautiously optimistic take came from Superform, which stated interoperability is largely “solved” for EVM-to-EVM applications, but admitted that moving between EVM, SVM, and Move chains is still difficult.
Taken together, the message is clear: foundational tooling exists, but seamless, abstracted cross-chain UX remains aspirational.
AAA: S2 Explores UX Challenges in Smart Wallets
ERC-4337 has released a new episode of AA Afterhours, featuring João Ferreira from Picnic. The discussion dives deep into session keys, wallet UX tradeoffs, and how account abstraction reshaped Picnic’s architecture.
The episode highlights practical challenges in smart wallet development, from bundler economics to missing dev tools, and how thoughtful design choices can make AA user-friendly and secure. Ferreira explains the importance of good defaults and abstractions that work across varied use cases without overwhelming either users or developers.
Watch the episode here: Smart Wallets, Session Keys & UX Challenges.
