Odaily reports that Josh Stevens, VP of Engineering at Polymarket, posted on X that the team has built its own indexing system using the open-source Rust tool rindexer. On-chain events can now be visible up to about 14 blocks earlier, roughly 28 seconds; the system can complete indexing within 0 to 10 milliseconds after a block is broadcast, approaching real-time.

The refresh speed for trades, positions, and balances will be further improved.

Odaily reports: Defillama founder 0xngmi posted on X that a new metric has been launched for trading platforms — Realized Perp Slippage. The specific methodology involves taking a snapshot of the order book at the moment just before a market order is executed, calculating the theoretical slippage at which the order should have been filled, and then comparing it with the actual slippage at real execution.

0xngmi added: "The reason we track this metric is that we initially focused on order book liquidity, but later found that due to mechanisms like speed preferences, in many cases orders cannot be executed as expected because market makers withdraw liquidity before order execution. So we started tracking actual liquidity conditions."

Odaily News: According to monitoring by @insidecalls and @cladzsol, recently multiple popular meme coin display pages have been directing users to phishing pages disguised as "Cloudflare verification." After users follow the prompts, their computer systems download and execute malicious scripts, resulting in on-chain asset theft. The relevant display pages directly reference the official website or social media links in the token metadata, and these fields can be updated by the token creator or individuals later claiming "community takeover."

Odaily reports that overseas crypto KOL Brady Dale posted on X, stating that three individuals are to blame for the failure of the CLARITY Act.

The first chief culprit is Trump, whose sin lies in launching a token, making moral justice the ultimate core point of contention.

The second chief culprit is Republican Senator Tim Scott, whose sin lies in stubbornly insisting that the Senate waste enormous time cooking up its own version, squandering what little momentum the earlier GENIUS Act had painstakingly built up.

The third chief culprit is Republican Senator Cynthia Lummis. As early as last fall, I already felt this whole thing was doomed.

Odaily: Argentina has committed to implementing the OECD's Crypto-Asset Reporting Framework (CARF) and will launch automatic exchange of tax information on crypto asset transactions by September 2029 at the latest. Argentina is required to incorporate the framework into its domestic law by 2029 and to clarify the reporting obligations of relevant crypto asset service providers.

Trading platforms, intermediaries, and other relevant service providers will be responsible for identifying qualifying users and collecting information such as names, addresses, tax residences, taxpayer identification numbers, and transaction details including crypto asset purchases, sales, and transfers. The measure will not introduce new taxes, nor does it mean users will automatically incur new tax obligations; Argentina's tax authority ARCA will be able to obtain standardized information on its residents' overseas crypto asset transactions and cross-reference it with tax returns. The first annual information reporting period under the mechanism has not yet been publicly determined.

Odaily reports that Japan's Financial Services Agency has published its "Fiscal Year 2026 Financial Administration Policy," proposing to clarify the technical, institutional, and regulatory challenges of onchain finance through public-private practical verification and dialogue, while ensuring user protection and financial system stability, and to build financial infrastructure that is both convenient and competitive.

Japan's Financial Services Agency will also advance the shortening and upgrading of securities settlement processes in conjunction with the development of asset tokenization, and plans to establish an onchain finance forum for the AI era to discuss the application of digital finance, decentralized finance, and AI technology in the financial sector.

Odaily reminds users that Meme coin prices are highly volatile, and investors should participate with caution.

According to Odaily, Cat monitoring shows that DeBot activated emergency protection after receiving a wallet security risk alert in the early hours of today, and the relevant wallets have been temporarily isolated. Native token and stablecoin assets will be mapped 1:1 into a new keyless wallet, while meme tokens will be partially transferred to the new wallet, which will still support safe trading.

During the protection period, users can withdraw and transfer out tokens as normal, but will temporarily be unable to export private keys, with the restoration time to be announced separately. As of the time of the announcement, no anomalies in user assets had been detected. After entering the migration process, users should stop using the old wallet and should not deposit or transfer assets into the old wallet; any newly added assets transferred into the old wallet after the migration begins may not be automatically migrated as part of this upgrade and may affect subsequent use. For other unmigrated on-chain assets or unmigrated meme tokens, users may transfer them on their own in a timely manner.
