Arkham announced integration with the x402 standard developed by Coinbase and governed by the Linux Foundation, enabling AI Agents to use USDC directly for real-time payment when calling Arkham APIs. Combined with Coinbase Agentic Wallet and Arkham API, AI Agents can automatically track fund movements of large on-chain addresses and analyze wallet cash flow changes. This integration provides a concrete product path for combining AI and blockchain: Agents can not only perform on-chain analysis, but also autonomously obtain required data and services through on-chain payments.

4. Solana Foundation New CISO Warns of Rising AI-Driven Security Risks

Solana Foundation's new Chief Information Security Officer, Michael Coates, said that security risks in the blockchain ecosystem are increasingly coming from AI-driven social engineering, deepfakes, and credential leaks, rather than being limited to smart contract vulnerabilities. He argued that project teams should provide multi-layered security controls in default configurations, rather than assuming users can identify all forms of fraud. Coates also highlighted post-quantum cryptography migration, stressing that identity verification, key and permission management, and abnormal transaction interception should continue independently of on-chain contract audits.

1. Japan Expands Travel Rule Jurisdictions for Cross-Border Transfers of Crypto Assets and Stablecoins

The revision announced by Japan's Financial Services Agency took effect on August 3 and added five jurisdictions to the scope of cross-border transfer information notification requirements for crypto asset service providers and electronic payment instrument service providers. The mechanism requires relevant service providers to transmit sender and recipient information when crypto assets or stablecoins are transferred across borders. This adjustment is an update to the scope of cross-border AML rules and does not mean Japan has established a new Travel Rule regime; previously, the obligation applied only to overseas jurisdictions with equivalent rules.

2. South Korean Lawmaker Plans Bill to Delay Virtual Asset Income Tax Implementation Until 2030

People Power Party lawmaker Jung Sung-guk plans to introduce a bill that would delay the taxation start date for gains from virtual asset transfers or lending from January 1, 2027 to January 1, 2030. Under the current plan, income related to virtual assets is set to be taxed as "other income" starting in 2027, with a 22% tax rate applied to the portion of annual profits exceeding 2.5 million won. The proposal is still in the early legislative stage.

The U.S. Senate has not yet made clear whether, or when, it will advance the CLARITY Act. Provisions related to anti-illicit finance, agriculture, and conflicts of interest for senior government officials are still under negotiation, and the White House is also reviewing an ethics proposal put forward by senators. If the Senate does not take procedural action before the August recess, discussion of the bill may be pushed into September. The bill is intended to establish a digital asset market structure regulatory framework and clarify the regulatory boundaries between the SEC and CFTC.

1. Should Ethereum Staking Be Capped? EIP-8363 Proposal Sparks Intense Debate️

https://www.panewslab.com/zh/articles/019fe13b-fc23-772c-b18d-f6f6a62787e7

Ethereum's staking rate has surpassed 33%, and an EF researcher has proposed EIP-8363, which would use a declining issuance burn mechanism to keep the staking ratio below 50%: as the staking ratio approaches 50%, newly issued rewards would be gradually burned, and once the threshold is crossed, validators would earn only from transaction tips and MEV. Supporters believe this could prevent validator monopolization and strengthen ETH's hard-money properties; opponents warn it would undermine DeFi benchmark interest-rate pricing and accelerate MEV centralization. The proposal has been marked PFI, and if it moves forward, there will be an 18-month transition period.
