EIP-8250 Keyed Nonces For Frame Transactions
--------------------------------------------

Thiery, Wahrstätter, Lightclient, and Vitalik proposed replacing the single sender nonce in frame transactions with a keyed nonce system, where each key operates as an independent replay-protection domain. The change eliminates a throughput bottleneck for privacy protocols, routing multiple users through one shared address. Vitalik has framed it as a first step toward a broader state scaling strategy for Ethereum. EIP-8250 is targeted for the Hegota upgrade.

Anonymous Credentials for Trustless Agents
------------------------------------------

The Ethereum Foundation PSE team introduced ACTA, a privacy extension to ERC-8004 that uses zero-knowledge proofs to let AI agents prove claims about reputation, jurisdiction, model provenance, without revealing underlying data on-chain. It addresses five gaps in ERC-8004, including its permanent public interaction graph and lack of anonymous reputation feedback.

KelpDAO Migrates rsETH To Chainlink CCIP
----------------------------------------

KelpDAO is migrating rsETH to Chainlink CCIP following the April 18 exploit. Kelp says that LayerZero's own infrastructure was the cause, not just a Kelp misconfiguration. Kelp added that it detected the breach itself before LayerZero. LayerZero CEO Bryan Pellegrino disputed the claim, citing onchain records showing Kelp manually switched to the vulnerable 1-1 DVN configuration.
