The upgrade includes optimizations for smart contract execution efficiency, reducing average gas costs by an estimated 12–15% in early tests. The testnet, named *Holesky-Pectra*, is scheduled for activation on mainnet in late June 2026.  \nSource: [ethereum.org/roadmap/pectra](https://ethereum.org/en/roadmap/pectra/) (updated April 8, 2026)\n\n### 2. **Chainlink Introduces Decentralized Oracle Automation 2.0 (April 6, 2026)**\nChainlink unveiled **Automation 2.0**, a major upgrade to its smart contract automation suite, enabling **conditional execution based on multi-oracle consensus** and **time-stamped data triggers** with millisecond precision. The system leverages staked oracle networks to reduce false triggers by 40% in simulation testing. The upgrade went live on Ethereum, Arbitrum, and Base on April 6, 2026. Over 1,200 DeFi protocols have already integrated the new system, including Aave and Synthetix.  \nSource: [chain.link/blog/automation-2-0-launch](https://chain.link/blog/automation-2-0-launch) (April 6, 2026)\n\n### 3. **zkSync Era Implements zkEVM Smart Contract Audit Framework (April 5, 2026)**\nMatter Labs launched a **mandatory smart contract verification layer** for zkSync Era on April 5, 2026, requiring all new contracts to undergo **automated zero-knowledge proof-based validation** before deployment.
