Mainnet

Ethereum developers have confirmed key testing dates for the Glamsterdam upgrade while warning that disposable builder identities could disrupt Sepolia block production. The issue does not threaten mainnet funds, but it could complicate infrastructure testing before the upgrade moves closer to Ethereum activation.

Hyperliquid is preparing an enhancement to its HIP-4 upgrade that would allow permissionless deployment of prediction markets on the decentralized exchange. The feature is slated to reach testnet before mainnet, while deployers would need to stake HYPE and operate within validator-approved templates.
