KelpDAO announced it is migrating rsETH from LayerZero to Chainlink's Cross-Chain Interoperability Protocol (CCIP) following the April 18 exploit that resulted in over $300M in losses. KelpDAO says the exploit originated within LayerZero's own infrastructure, not a misconfiguration.

KelpDAO also pushed back on LayerZero's public framing of the incident, arguing that the 1-1 DVN configuration was not unique to Kelp and was used by over 47% of LayerZero’s ecosystem at the time. Kelp also highlights that it detected the exploit itself and alerted LayerZero, rather than being warned by them.

LayerZero CEO Bryan Pellegrino responded to the claims, stating that KelpDAO started with a multiDVN setup of LayerZero Labs and Google, but later changed its configurations to the 1-1 DVN.

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.
