Project Overview
Tornado Cash is a decentralized and non-custodial privacy solution. It improves transaction privacy by breaking the on-chain link between source and destination addresses. This is achieved through a smart contract that accepts ETH and other token deposits from one address, and enables their withdrawal from a different address.
CLARITY Act Hearing Live: AI Regulatory Sandbox Amendment Passes, Amendment to Block High-Risk Assets from Retirement Accounts Rejected
the deliberation of the "Cryptocurrency Market Structure Act" (i.e., the CLARITY Act) has commenced in the U.S. Senate Banking Committee. As of now:1. An amendment proposed by Senator Mike Rounds to create an AI regulatory sandbox was passed with 15 votes in favor and 9 against, indicating some bipartisan support, despite Senator Elizabeth Warren urging Democratic members to vote against it.2. An amendment proposed by Elizabeth Warren, aimed at "preventing high-risk assets from entering retirement accounts," was rejected with 11 votes in favor and 13 against.3. An amendment previously proposed by Senator Katie Britt of Alabama, which would have allowed certain retirement accounts to invest in pooled investment vehicles, was withdrawn before the vote.It is reported that one of the most contentious amendments comes from Elizabeth Warren, concerning the strengthening of sanctions authority over cryptocurrency mixers. In her remarks, she referenced the U.S.-sanctioned mixing protocol Tornado Cash, stating it has been used to launder over $7 billion for criminal organizations and North Korean hacker groups, including over $450 million in related funds. Warren argued that the current bill does not grant the U.S. Treasury Department sufficient legal authority to isolate or restrict mixer services, potentially creating loopholes in anti-money laundering oversight. In response, Cynthia Lummis countered that the illegal financial activities are already covered in Parts Two and Three of the bill.
Senator Warren questioned the adequacy of anti-money laundering tools during the hearing, citing Tornado Cash as an example
Odaily News: Crypto In America journalist Eleanor Terrett posted on X platform, stating that Tornado Cash became the focus of the day's hearing, with lawmakers debating whether the bill provides law enforcement with sufficient tools to combat money laundering.Senator Warren told Kennedy: "This is the Tornado problem...

Republican lawmakers argued that the Clarity Act provides tools to address this issue, while Warren stated the bill is insufficient. Other Democrats joined her in voting to support the inclusion of the amendment. The amendment did not pass.

According to monitoring by on-chain analyst PeckShield (@PeckShieldAlert), the public OLP vault of decentralized perpetual contract protocol Ostium (@Ostium) was attacked, with approximately 24 million USDC stolen. The attacker subsequently swapped the stolen funds for 12,080 ETH and has transferred 10,540 ETH into the mixer Tornado Cash to obscure the fund flow.

Odaily Odaily News According to Onchain Lens monitoring, on July 6, the Summer.fi attacker wallet (0x7BF...b3bdca) received 6.017 million DAI from the Summer.fi attack incident; subsequently, 1.35 million DAI have been transferred, swapped for ETH via Uniswap, and then sent to Tornado Cash through a second wallet (0x46e...eba7). The original wallet still holds approximately 4.67 million DAI, while the second wallet still holds 50 ETH.
Ostium Attack Post-mortem: Off-chain Oracle Permissions Stolen, Forged BTC Price to Arbitrage 23.75 Million USDC
According to Ostium's official report, the core of this attack lies in the compromise of the off-chain price reporting system permissions, unrelated to smart contract vulnerabilities. After obtaining off-chain authorization, the attacker utilized the protocol's registered legitimate forwarding paths to submit forged prices ($5,000 and $60,000) to the BTC-USD market, atomically completing an open-close position arbitrage cycle within the same transaction. Starting with 100 USDC and rolling to amplify the scale across 8 transactions, they extracted 23.75 million USDC from the OLP vault within 5 minutes until the vault circuit breaker mechanism was triggered. The root cause lies in the off-chain infrastructure lacking a multi-party approval mechanism equivalent to on-chain multi-signature, creating a single-point permission vulnerability. The stolen funds have been converted to ETH and mixed via Tornado Cash; tracking efforts are still ongoing.

All affected users will be fully compensated at a 1:1 ratio, with specific compensation procedures and timelines to be announced in a subsequent update.
Ethereum Foundation’s Kohaku Launches Wallet Privacy Integration SDK, Enabling Ethereum Wallets to Integrate Protocols Such as Railgun
According to The Defiant, the Ethereum Foundation’s Kohaku Initiative has released an SDK for integrating privacy protocols into Ethereum wallets. A functional 4337 mempool relay supporting private transactions is now available in version v0.0.1-alpha.21 of the kohaku-eth/railgun integration. This SDK aims to integrate shielded-pool protocols—such as Railgun, Tornado Cash, and Privacy Pools—directly into wallet interfaces, reducing reliance on centralized relay infrastructure. Kohaku has also demonstrated a CLI-based wallet and is advancing integration with production-grade wallets like Ambire, while simultaneously developing post-quantum accounts, multisig support, and hardware wallet compatibility.

Wasabi Protocol attacker has deposited all stolen funds into Tornado Cash
According to monitoring by on-chain analyst Specter, the Wasabi Protocol attacker has deposited all stolen funds into Tornado Cash, moving approximately $5.9 million into Tornado Cash. Additionally, North Korean hacking groups have also used Tornado Cash to launder stolen funds from KelpDAO and LayerZero. Their process involved first cross-chaining the assets to Bitcoin, then routing them through Wasabi Mixer, extracting and cross-chaining back to Ethereum, depositing into Tornado Cash, subsequently withdrawing to new wallets and dispersing across multiple addresses. The new wallets then deployed tokens, used the stolen funds to buy in, removed liquidity from the deployment wallet, cross-chained to Tron (USDT), held for several hours or days, and finally sent to OTC-related wallets.
