Spire Labs launched Full Send, a free RPC endpoint that delivers fast Ethereum mainnet transaction inclusion with MEV protection against frontrunning and sandwich attacks, plus revert protection against failed transactions. Users can simply add the custom RPC endpoint (rpc.fullsend.to) in one click to any EVM wallet, including MetaMask, Rabby, and Rainbow. The Full Send RPC is free, self-custodial, and built on DA Builder, Spire’s aggregation layer focused on bringing account-abstraction-like features directly to the RPC layer for faster, safer, and more reliable transaction propagation. Spire Labs is an Ethereum scaling and execution infrastructure provider focused on based rollups.

Etherscan removed chains like Base, Optimism, and BNB Chain from its free API tier coverage, effectively paywalling access to some high-volume networks. Users must now upgrade to a paid plan to regain access. Etherscan cited transaction growth and infrastructure strain as the reason, stating that unrestricted free access to every chain was no longer sustainable. The change, implemented with little advance notice, sparked backlash. In response, developers are exploring alternatives, including BlockScout, which offers free APIs for Base and OP Mainnet, Routescan, QuickNode, and Sourcify.

Privacy Pools, an Ethereum onchain privacy protocol developed by 0xBow, now supports deposits as low as 0.01 ETH, making private transfers accessible for smaller amounts. Users deposit ETH into a shared privacy set and, after a required holding period, can withdraw to an unlinked address using zero-knowledge proofs that prove ownership without revealing the deposit address. The latest update also significantly speeds up deposit approvals during the compliance screening process. 0xBow recently raised a $3.5 million seed round. Privacy Pools has already processed over 1,000 ETH in deposits and more than $6 million in total volume.

The Ethereum Foundation announced Mumbai, India, as the location for the eighth Ethereum Developer Conference, known as Devcon VIII. The event will take place in Q4 2026. The foundation chose the location due to India's leading crypto adoption, crypto developer base, and fastest-growing developer populations worldwide. Community members can contribute to shaping the event by submitting Devcon Improvement Proposals (DIPs).
