Linea Build Announces Mint ezETH and Bridge to Linea Rollup

Linea's cryptography team has released **Small Fields**, a major upgrade to their zero-knowledge prover system. **Key improvements:** - Faster proving times - Reduced operational costs - Lighter computational requirements - Progress toward decentralizing the prover role This technical advancement represents a concrete step in Linea's roadmap toward achieving real-time finality for transactions on their zkRollup.

**EIP-7702 is now live on Linea**, enabling existing Ethereum accounts to execute smart contract functionality without migrating addresses or switching wallets. **Key capabilities unlocked:** - Transaction batching - Gas sponsorship - Session keys - Account recovery - Smart contract logic execution The upgrade eliminates the traditional choice between simple private key accounts and powerful smart contract wallets. **EIP-7702 is fully compatible with ERC-4337**, the existing smart account standard, allowing users to benefit from both approaches. With native MetaMask integration, these features reach **30M+ existing users** immediately, requiring no new onboarding flow. Every account abstraction upgrade landing on Ethereum mainnet will be available on Linea 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—similar to a scoped, revocable power of attorney. **Key features:** - Your address remains unchanged - You retain full ownership of your keys - Delegation can be revoked in a single transaction This mechanism allows controlled autonomy for operations like AI agents managing portfolios, while maintaining custody. Users can set specific permissions—such as token swaps, protocol interactions, and spending limits—through one signature. The system prioritizes **user control**: rights can be revoked at any time, and the delegation operates within predefined boundaries. This shifts the focus from trust to defining appropriate tasks within a secure framework.

Linea has published an update to its documentation page. The zkEVM rollup's technical documentation is available at docs.linea.build for developers building on the network. **Key Points:** - Documentation refresh for Linea's developer resources - Updates available on the official [Linea Docs](https://docs.linea.build/) page - Follows previous documentation updates from earlier this month Linea continues to maintain its technical documentation for developers working with the zkEVM scaling solution.
