Polymarket, the world's largest prediction market platform, received CFTC approval via an Amended Order of Designation, allowing it to operate as a fully regulated U.S. exchange. The approval enables intermediated trading, where users access markets through licensed brokers and FCMs, integrating with traditional custody systems. CEO Shayne Coplan praised the current administration for their speed and feedback on applications, stating that “this admin and commission are built differently.” Polymarket allows users to bet on real-world event outcomes across elections, sports, and markets.
Sunnyside Labs, a core contributor to the OP Stack, and OP Labs introduced backup sequencing on OP Mainnet, allowing the sequencer set, previously operated solely by OP Labs, to include Sunnyside Labs as a backup. A sequencer failure forces users to fall back to the slow L1 forced transaction. The new system uses op-conductor, a Raft-based program, to manage sequencer failover. There are currently five sequencers, 3 by OP Labs and 2 by Sunnyside Labs, spanning multiple cloud providers. The transition from a single operator to a multi-operator model ensures continuous block production and moves towards sequencer decentralisation for the Superchain.
GnosisDAO approved a proposal to terminate its four-year treasury management relationship with DAO treasury manager Karpatkey. The vote follows debates over costs, risk, performance, and alignment following Karpatkey’s 2024 spin-out into an independent entity. All treasury assets will be returned to direct GnosisDAO control. The assets will eventually be consolidated into sUSDS, wstETH, and Gnosis ecosystem tokens. Karpatkey, originally incubated by Gnosis in 2021, continues managing treasuries of other protocols, including the ENS DAO and Balancer.

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).

The ZKsync Airbender open-source prover is now capable of proving every Ethereum L1 EVM block using just two NVIDIA RTX 5090 GPUs. The milestone, announced ahead of the ethproofs.day demo, significantly reduces the hardware requirements from previous benchmarks of a single H100 GPU, making home-proving on consumer-grade hardware more feasible. Airbender is a high-performance RISC-V-based zkVM, enabling real-time settlement and cross-chain coordination, supporting local proof generation, and dramatically reducing ZKsync proving costs to just $0.0001 per transfer.
Layerswap, a cross-chain bridge and on- and off-ramp provider, disclosed a bug in its application that allowed users to swap or bridge stablecoins to ETH at a 1:1 ratio. One user exploited the flaw and withdrew over 80 ETH using just 80 DAI. Layerswap stated that the developer responsible for the bug is no longer with the company. Layerswap sent an onchain message to the user, offering a 10% white-hat bounty in exchange for returning the funds. The user ultimately sent back the requested ETH. Layerswap enables transfers between centralized exchanges and L2 networks, as well as cross-chain bridging between supported chains.
Trails introduced its universal intents platform for enabling 1-click transactions across any chain, any token, and any wallet. The platform allows users to access their aggregate spending power across all their wallets. Trails features a gasless experience, allowing users to pay transaction fees using any permit-compatible ERC20 token. For developers, Trails offers a plug-and-play widget and the Trails Intents API for easy integration into their apps, including gasless HTTP payment authentications using x402. The platform also features integrations with Circle CCTP transfers and Katana yield vaults.
Sigma Prime released Lighthouse v8.0.1 as a hotfix containing several bug fixes and performance improvements, including a change that fetches checkpoint blobs from p2p peers. Ethereum nodes running Lighthouse must upgrade to v8.0.1 ahead of the Fusaka upgrade on December 3, 2025.
