Gm frENS. It's only Monday, but it's been busy!

• The Holešky testnet begins its sunset process.

• An AWS outage impacts RPC providers.

• Primev releases a Fast RPC endpoint.

• Vitalik outlines the GKR Protocol.

• Nethermind v1.35 with 60m gas limit.

The Holešky testnet has started its scheduled shut down process. The testnet has been set to go offline two weeks after the Fusaka upgrade finalized on the testnet, which occurred on October 1. Application and tooling developers are encouraged to migrate to the Sepolia testnet, while staking infrastructure providers are advised to transition to the Hoodi testnet. Holešky was launched on September 28, 2023, as a proof-of-stake testnet intended to replace Goerli. At genesis, it featured an active validator set of 1.46 million, designed for staking infrastructure testing. The network allowed open participation as public validators. Ethereum testnets typically have a lifespan of up to five years.

Amazon’s AWS US-East-1 region experienced a major outage early Monday morning due to a DNS resolution failure in the DynamoDB API endpoint. The outage disrupted numerous AWS services that depend on the region’s endpoints, including DynamoDB Global Tables, IAM, and CloudFront CDN. RPC providers, such as Infura, were impacted, causing its users to experience delays or failures in sending transactions. Some Ethereum validators hosted on AWS also faced temporary disruptions. Notably, Ethereum’s mainnet has maintained near-100% uptime over the past decade.

Ethereum infrastructure provider Primev released a Fast RPC endpoint enabling millisecond transaction preconfirmations on Ethereum L1. Users can add the endpoint to their wallets for faster, more reliable transaction inclusion. In a demo, an ETH transfer was preconfirmed in 377 ms and included in the same block. The implementation leverages mev-commit, a decentralized network of block builders that issue and honor transaction commitments before block inclusion. Preconfirmations provide early transaction confirmation guarantees, improving the user experience. Dapps can also configure the Fast RPC endpoint.

Vitalik Buterin published an article outlining the GKR protocol, a protocol which can power ultra-fast Zero-Knowldege Proof (ZKP) generation used in ZK-EVM and zkML systems. The protocol achieves extreme efficiency by proving large, structured computations like Poseidon hashing or neural network inference without committing to intermediate states. GKR makes real-time zk-proofs feasible, significantly lowering computational overhead while maintaining succinctness.

• Huobi founder leads $1B ETH Trust.

• Burned ETH builder grants.

• OpenSea confirms SEA Q1 2026.

Li Lin, founder of Asia-based crypto exchange Huobi, is reportedly launching a $1 billion Ethereum trust company aiming to accumulate and hold ETH as a long-term treasury asset. The initiative, similar to recent efforts using Nasdaq-listed entities for structuring, has backing from major investors in Asia, including Fenbushi Capital, HashKey Group, and Meitu. Avenir Capital, which is chaired by Li Lin, has committed $200 million of the targeted $1 billion fund, which would make the trust the fourth-largest corporate holder of ETH once completed.

The Ethereum Community Foundation launched the Burned ETH (BETH) Builder Grants, offering $50,000 in total funding for projects that expand BETH adoption. BETH is an ERC-20 token representing provably burned ETH. When ETH is sent to the BETH smart contract, it is permanently burned, and an equal amount of BETH is minted 1:1 as an onchain proof of burn. The program invites proposals for L2 Burn Bridges, Burn Leaderboards, airdrop/incentive frameworks, integrations, developer tooling, governance systems, and culture projects. BETH aims to make burn data a transparent, onchain metric of alignment with Ethereum’s monetary base. Applications are open through the end of October.

OpenSea co-founder and CEO Devin Finzer confirmed that the marketplace will launch its native $SEA token in Q1 2026. 50% of the total supply will be allocated to the community, with over half of that distributed through an initial claim. He added that both OG users and rewards program participants will be meaningfully considered. $SEA will be a utility token, with staking features launching next year. Additionally, 50% of launch revenue will go toward buying back $SEA. OpenSea is also expanding beyond NFTs, into a unified onchain trading platform that integrates perpetual trading, cross-chain support, and an upcoming mobile app.

• MegaETH real-time data streams.

• Introducing a private multisig.

• Base introduces creator coins.

• SharpLink raises $76.5 million.

MegaETH, in collaboration with Chainlink, introduced native, real-time data streams on MegaETH. The integration embeds Chainlink Data Streams directly into MegaETH’s execution environment through a native precompile, enabling smart contracts to access live, high-frequency market data with sub-second latency. The release enables CEX-level performance for DeFi, allowing real-time updates for perpetuals, prediction markets, and stablecoins. By combining Chainlink’s oracle networks with MegaETH’s 10ms block times and 100,000 TPS architecture, the integration establishes a new standard for real-time DeFi, bridging the speed gap between decentralized and traditional financial systems.

Solidity maintainer Artem Chystiakov released a paper introducing a privacy-preserving, zero-knowledge (ZK) multisignature wallet for Ethereum. The system preserves anonymity and confidentiality in multisig approvals and voting while eliminating centralized trust. The architecture includes two smart contracts, ZK circuits, and relayers to support private and verifiable onchain operations. The design replaces interactive key-sharing with deterministic derivation and ensures all cryptographic actions are ZK-verifiable and auditable onchain without leaking private data.

SharpLink Gaming, Inc. raised a $76.5 million from a direct offering of 4.5 million shares at $17.00 per share. SharpLink is also offering institutional nvestors a 90-day option to purchase up to 4.5 million additional shares at $17.50, which could generate an extra $78.8 million if fully exercised. Co-CEO Joseph Chalom said the premium-priced financing is accretive to shareholders, allowing SharpLink to expand its ETH holdings and increase ETH-per-share value. The company currently holds over 840k ETH.
