The Ethereum Foundation PSE team introduced Anonymous Credentials for Trustless Agents (ACTA), an extension to the ERC-8004 standard that allows agents to prove claims about personhood, reputation, model provenance, and user jurisdiction. It uses zero-knowledge proofs to verify claims without revealing underlying data.

ACTA was created to address the permanent public interaction graph, linkability across sessions, lack of selective credential disclosure, lack of anonymous reputation feedback, and traceable cross-registry profiles in ERC-8004, the onchain trust standard for AI agents. The extension is currently in a draft phase. The PSE team is actively soliciting protocol design proposals.

Thomas Thiery, Toni Wahrstätter, Lightclient, and Vitalik Buterin introduced EIP-8250, a proposal to replace the single sender nonce used in frame transactions with a keyed nonce system. Under EIP-8250, each key selects an independent nonce sequence, so transactions using different keys are completely replay-independent.

The new system is particularly beneficial for privacy protocols, which route many independent users through a single shared sender address. Frame transactions currently consume one linear nonce per sender. If one transaction is delayed, every subsequent transaction from the same sender is invalidated.

Vitalik has also framed keyed nonces as a first step toward a broader state scaling strategy: creating specialized, restricted forms of storage on Ethereum that can scale to hundreds of billions of entries while remaining more manageable for decentralized node operators. EIP-8250 is targeted for inclusion in the Hegota upgrade.

• Law firm files notice to ArbDAO.

• Upbit launches GIWA Chain on OP Stack.

Gerstein Harrow LLP filed a restraining notice in SDNY against Arbitrum DAO, blocking the transfer of 30,766 ETH frozen from the KelpDAO exploit. The firm argues the funds are DPRK-linked property and can be seized to satisfy a decade-old default judgment for its clients. ZachXBT called the move "pure evil," noting Gerstein Harrow is the same firm behind the notorious PoolTogether lawsuit. Read more.

Aave LLC filed an emergency motion to vacate the SDNY notice, arguing that a thief does not gain legal title to stolen property, the ETH belongs to KelpDAO victims and downstream DeFi users. Aave is requesting Gerstein Harrow's clients to post a $300M bond if the notice stands. The DAO transfer to a recovery multisig could remain blocked pending the court's decision. Read more.

Ethereum core devs agreed to target a 200M gas limit floor after Glamsterdam, unlocked by ePBS, Block-Level Access Lists, and EIP-8037 state repricing. The decision came out of Soldøgn Interop, a week-long gathering of over 100 core contributors in Svalbard. Final figures will be confirmed on upcoming AllCoreDevs calls. Read more.

South Korea's largest crypto exchange Upbit announced GIWA Chain, its own Ethereum L2 built on the OP Stack via Optimism's self-managed OP Enterprise tier. Upbit will run its own sequencer and retain full control while the Optimism Foundation provides backup infrastructure. The testnet is live, with a mainnet launch to follow. Read more.

Researcher Toni Wahrstätter outlined how Frame Transactions (EIP-8141) could let privacy pools pay withdrawal fees directly from the withdrawn funds, removing the centralized relayer dependency that protocols like Tornado Cash rely on today. With targeted changes, privacy transactions could match the censorship resistance of ordinary Ethereum transactions. Read more.
