**EIP-7702 is now live on Linea**, enabling existing wallets to execute smart contract functionality without address migration. **Key capabilities unlocked:** - Transaction batching - Gas sponsorship - Session keys - Account recovery - Smart contract logic execution **Compatibility & reach:** - Fully compatible with ERC-4337 (existing smart account standard) - Native MetaMask integration reaches 30M+ users - No new wallet or onboarding required **The breakthrough:** EIP-7702 eliminates the historical tradeoff between simple private key accounts and powerful smart contract wallets. Users gain smart account features while keeping their existing addresses. Linea commits to implementing every account abstraction upgrade that lands on Ethereum mainnet as part of their roadmap toward full native account abstraction.

Linea has announced new smart account capabilities that simplify blockchain interactions: **Key Features:** - **Combined transactions**: Approve and swap tokens in a single step - **Flexible gas payments**: Pay transaction fees in USDC, mUSD, or any ERC-20 token instead of just ETH - **Session keys**: Grant temporary, time-limited access to apps or bots - **Guardian recovery**: Add backup recovery options to existing wallet addresses These improvements aim to reduce friction in using decentralized applications by eliminating multiple transaction steps and offering more payment flexibility. The session key feature allows users to automate certain actions without compromising full wallet control, while guardian recovery provides an additional security layer for account access. The updates build on previous guidance about token approvals, where users were reminded to regularly revoke old permissions to maintain security.

A new transaction type enables **temporary delegation** of account authority to smart contract logic while maintaining full ownership and control. **Key features:** - Your address and private keys remain unchanged - Delegation functions like a scoped, revocable power of attorney - Can be reversed in a single transaction - Provides autonomy within defined boundaries This builds on Smart Sessions technology, which allows grouping multiple permissions into one gasless transaction. Users can grant specific rights—like token swaps or protocol interactions—while setting spending limits across chains. **Control remains paramount:** delegation can be revoked at any time, shifting the focus from trust to task selection.

**Uniswap has launched full integration with Linea**, the zkEVM layer-2 network. The deployment includes: - Uniswap v2, v3, and v4 protocols - Uniswap Web App support - Uniswap API integration - Uniswap Wallet compatibility (rolling out on iOS and Android) Linea is a zero-knowledge rollup built by ConsenSys designed to scale Ethereum applications. The integration gives Linea users access to Uniswap's complete decentralized exchange infrastructure across all protocol versions. This marks another expansion of Uniswap's multi-chain strategy, bringing its trading capabilities to Linea's zkEVM environment.

Linea announced a major technical pivot from direct EVM arithmetization to RISC-V architecture. The decision comes after three years of development that produced a 1000+ page specification and what the team describes as one of the most rigorous proving systems in production. **Key Points:** - Transition to RISC-V architecture confirmed at recent presentations - Previous work included extensive EVM arithmetization efforts - Team presented the roadmap and rationale at industry events - Further details to be shared in upcoming communications The shift represents a significant strategic change for the zkEVM project, moving away from their original technical approach despite substantial prior investment in EVM-focused development.
