Sepolia marks one of the final major rehearsals before the final activation of Glamsterdam, aimed at bringing more efficiency and scalability to the Ethereum mainnet. Ethereum’s Glamsterdam upgrade has gone live on the Sepolia testnet, in one of the final major rehearsals before its mainnet activation. Glamsterdam went live on Sepolia on Tuesday at 1:53 pm UTC, Ethereum community contributor Pooja Ranjan announced in an X post. The upgrade aims to advance Ethereum’s layer-1 scaling roadmap with enshrined proposer-builder separation, block-level access lists and changes to gas pricing that better reflect the cost of execution, the Ethereum Foundation announced in a Sept. 28 blog post.

An EEZ contributor shared a 0.001 ETH cross-chain test as the project develops a framework to connect Ethereum mainnet and its rollups. The Ethereum Economic Zone (EEZ) has tested an atomic transaction between Ethereum mainnet and a layer-2 network, according to a project contributor. On Tuesday, EEZ contributor Eduardo Antuña Díez shared the transaction and called it the “first atomic cross-chain” L1-to-L2 transaction. The transaction’s logs record a cross-chain call carrying 0.001 Ether (ETH) and a state update for a rollup. In an atomic transaction, linked actions across networks either all succeed or are all reversed if any part fails. Read more
Once among Ethereum’s largest layer-2 networks by total value locked, Blast is urging users to move their assets to mainnet ahead of the shutdown. Ethereum layer-2 network Blast is shutting down after its operating costs exceeded the revenue generated by the chain. In a Friday post on X, Blast said it sees no “credible path” to making the network economically sustainable and asked users to withdraw their assets to Ethereum mainnet. “We launched Blast with the goal of building a self-sustaining chain for users and developers,” the team said. “Unfortunately, the economics of operating the chain no longer make sense.” Read more
Ethereum’s zkAPI is now live on mainnet, turning an earlier zero-knowledge API payment proposal into a working implementation for private, prepaid access. The Ethereum Foundation announced on Thursday that zkAPI, a system built with the Open Anonymity Project to let users pay for AI and other API services without revealing their billing identities, has gone live on Ethereum mainnet. Users deposit funds into an Ethereum vault, then use zero-knowledge proofs to prove they have enough credit to pay for API requests without revealing which deposits are theirs, according to a post from Vittorio Rivabella, AI coordinator at the Ethereum Foundation’s dAI team. One of the immediate use cases of the system is paying for the use of AI without linking the payment to a user. zkAPI issues short-lived API keys with predefined spending limits. Prompts are sent directly to the AI provider, while usage is settled separately through the payment layer. The project has also released a local client and software development kit, a...
MetaMask said it is investigating the threat internally and said it has found no immediate threat to its wallets. MetaMask has announced it is responding to a security incident affecting part of its infrastructure and is exiting affected staking validators as a precaution. In an update on Wednesday, MetaMask said it was addressing the ongoing threat internally and was working with external partners and security advisors. It did not share what the security issue was but said it has not identified any immediate threat to MetaMask wallets. Source: MetaMask Read more
Glamsterdam will bring proposer-builder separation, block-level access lists and new gas pricing, while its mainnet date remains unset. Ethereum developers have scheduled the network’s next major upgrade, Glamsterdam, to activate on the Sepolia testnet on Oct. 6. Sepolia node operators must update both their execution-layer and consensus-layer clients before the activation, the Ethereum Foundation said Monday. One of Glamsterdam’s changes is enshrined proposer-builder separation. It will move the handoff between specialized block builders and validators into Ethereum’s protocol, reducing reliance on outside middleware. Read more
Ethereum’s Vitalik Buterin said PeerDAS marked the start of Ethereum’s transition “from being just a blockchain to being something much more powerful.” Ethereum co-founder Vitalik Buterin said Ethereum’s Hegotá upgrade could be the network’s last “normal” fork before development shifts toward technologies that include recursive STARKs, automated formal verification, optimized consensus and quantum-safe cryptography. On Sunday, Buterin said Hegotá, which is planned for 2027, is likely to be the final upgrade whose features and technology would still be recognizable to someone familiar with Ethereum in 2015. He said PeerDAS, which allows nodes to verify data availability by sampling portions of data rather than downloading everything, marked the beginning of Ethereum’s transition “from being just a blockchain to being something much more powerful.” Read more
