FinCEN Withdraws Crypto Rules Targeting Mixers And Unhosted Wallets

TL;DR

  • FinCEN has withdrawn two proposed digital-asset rules covering unhosted-wallet transactions and convertible virtual currency mixing.
  • Both proposals had remained unfinished for years and would have added new recordkeeping or reporting obligations for financial institutions.
  • The withdrawals do not remove the AML and KYC rules that already apply to regulated crypto businesses.

Two long-running U.S. crypto rule proposals have finally been taken off the table.

The Financial Crimes Enforcement Network said on October 5 that it is withdrawing separate proposals dealing with transactions involving unhosted wallets and convertible virtual currency mixing.

Neither rule ever became final, but both had hung over the industry as examples of how far transaction-level reporting requirements could be extended.

Two Old Proposals Are Now Formally Dead

The first proposal would have imposed additional recordkeeping, verification and reporting requirements on certain transactions involving convertible virtual currencies and unhosted wallets.

The second involved a special measure aimed at cryptocurrency mixing activity.

FinCEN said it considered the public comments received on the proposals before withdrawing them. The agency framed the move as part of a wider effort to make digital-asset regulation more fit for purpose.

For wallet developers and privacy-focused users, the significance is not that financial surveillance has disappeared. It is that these specific proposals will not progress in their existing form.

That distinction matters.

Regulated exchanges, banks and money-service businesses still operate under existing anti-money-laundering obligations, sanctions rules and customer-identification requirements. FinCEN has not switched those off.

A Regulatory Threat Has Been Removed, Not The Rulebook

The withdrawals close two files that had generated substantial criticism over privacy, implementation and the treatment of self-custodied transactions.

They also give the industry a cleaner view of the policy landscape than it had when the proposals remained technically alive but unfinished.

That does not prevent FinCEN or Congress from returning to similar issues through a different rulemaking process in the future.

For now, however, there is a meaningful procedural change: the two proposals are no longer pending.

In crypto regulation, that kind of status change can matter as much as a new rule. Companies can stop planning around two specific frameworks that might once have reshaped how certain wallet and mixer transactions were reported, while continuing to operate inside the AML requirements that already exist.

Justin Sun Prize’s New Round Honors Human–AI Collaboration on Erdős Problems

Geneva, Switzerland — October 5, 2026 — The Office of Justin Sun today announced the newest recipients of the Justin Sun Prize: independent researcher Wouter van Doorn, mathematics Ph.D. student Quanyu Tang, and mathematics researcher Yanyang Li from Nanjing’s Southeast University, recognized for contributions spanning six Erdős problems.

Wouter van Doorn is an independent number theorist who began researching mathematics as an undergraduate in 2010 and continued collaborating and publishing after leaving academia following his master’s degree. Quanyu Tang (汤泉宇) is a mathematics Ph.D. student at the University of Science and Technology of China whose research spans number theory, combinatorics and AI-assisted mathematical discovery.

Erdős problems are mathematical questions posed or popularized by Hungarian mathematician Paul Erdős about numbers, patterns and other mathematical structures. Often simple to state but difficult to solve, they have helped shape research in number theory and combinatorics, with some remaining open for decades. The Erdős catalog, compiled and maintained by Thomas Bloom, a mathematician and Royal Society University Research Fellow at the University of Manchester, has more than 1200 problems. 

Van Doorn and Tang worked with Yanyang Li, from Southeast University’s School of Mathematics in Nanjing, to solve Erdős Problem #650, determining exactly how many integers can always be matched to distinct multiples within a specified interval. Van Doorn also produced computer-checkable proofs in Lean, software for verifying mathematical reasoning, for #369, concerning consecutive integers with restricted prime factors; #457, about whether a short run of consecutive integers can collectively contain every prime in a given range; and #469, concerning whether the reciprocals of a special class of numbers expressible as sums of their divisors add to a finite total.

Tang separately resolved #1044, establishing a sharp lower limit for boundary lengths of regions defined by polynomials, and contributed alongside Li to a wider team’s solution of #1196, bounding weighted sums over sets of integers in which no member divides another.

Their work on #650 offers a concrete example of how human judgment and AI can complement each other. ChatGPT helped develop the proof strategy, while Aristotle, an AI system for mathematical reasoning, repaired a gap during Lean formalization. The researchers then simplified the argument and wrote the final proofs and exposition.

“This experience taught me how public feedback can sharpen a research question, and how AI-assisted discovery can combine mathematical judgment, collaboration and rigorous verification,” Tang said.

These are the program’s first confirmed awards, recognizing both mathematical discovery and the work needed to make proofs independently checkable. Information about the Justin Sun Prize, its problem catalog and recipient contributions is available through the program’s public GitHub repository.

The prizes will be paid out in either USDT on TRON (TRC-20) or USDC on Ethereum (ERC-20) based on the recipient’s choice. For more information, please visit www.hejustinsun.com/prize.

About Justin Sun Prize 

The Justin Sun Prize is an academic initiative established by Justin Sun to support advances in mathematics, formal verification, and AI-assisted scientific discovery. The prize is decentralized and built around the principle that mathematical work should be judged by the strength, rigor, and verifiability of the proof itself, not the prestige or reputation of those submitting it.

 

Justin Sun established the prize in his own name as a long-term commitment to return wealth created through mathematics and technology back to mathematics itself. Its legacy is intended to be defined by the body of work it recognizes and the laureates whose discoveries stand the test of time. The prize links clearly defined mathematical challenges to machine-verifiable proof. Its guiding principles are openness, public benefit and open-source access.

MEXC and Payward Signal Intent to Explore Broader Collaboration Ahead of TOKEN2049

Mutsamudu, Comoros, October 5, 2026, MEXC, a pioneer in 0-fee digital asset trading, and Payward, the parent company of Kraken, are in discussions to explore a collaboration as both platforms look at how exchanges can better serve users across evolving global markets. The two companies will bring the conversation to TOKEN2049 Singapore, where MEXC CEO Vugar Usi Zade and Payward Co-CEO Arjun Sethi will join a panel on the MEXC Stage to discuss the next phase of trading platforms and share further perspectives on collaboration between exchanges.

 

The discussion comes as trading platforms respond to several shifts happening at the same time. Users are seeking broader access across crypto and traditional markets, AI is changing how investors research and interact with trading tools, and social trading is creating new ways to discover and participate in market opportunities. Against this backdrop, exchanges are increasingly looking beyond individual products toward how market access, infrastructure, liquidity and user experience can work together more effectively. As platforms evolve, exchange security and user asset protection will also remain an important part of the conversation.

 

As the exchange industry evolves, platforms are building different strengths across user experience, market access, infrastructure and trading capabilities. MEXC has focused on retail user experience, deep liquidity and perpetual trading across crypto and TradFi assets, while Payward brings global compliant financial infrastructure, professional trading capabilities and a strong U.S. market presence. These different strengths create room to explore where broader collaboration could add value for users.

 

“Users increasingly expect broader market access without more complexity,” said Vugar Usi Zade, CEO of MEXC. “The next stage of trading will require strong user experience, liquidity, infrastructure and market access to work more closely together. As exchanges continue to evolve, there is growing room to explore where collaboration across the industry can create more value for users.”

 

The TOKEN2049 panel will take place on October 7 from 12:30 to 13:00 at the MEXC Stage, and will explore the trends reshaping trading, how exchanges are preparing for changing user expectations, and where greater collaboration between platforms could create value. The conversation will also look at the convergence of crypto and TradFi, the growing role of AI in trading, and how global trading platforms may evolve as markets and infrastructure become more connected.

QNT Reaches Solana Liquidity Through Sunrise And Raydium

TL;DR

  • Quant’s QNT token is now available on Solana through Sunrise infrastructure, with trading available through Raydium.
  • The expansion gives Solana users a route into QNT liquidity without implying that Quant has abandoned Ethereum.
  • The event is a cross-chain market-access expansion, not a migration of the QNT ecosystem away from its existing networks.

QNT has gained a new Solana route, putting one of crypto’s longer-running interoperability tokens into the network’s DeFi liquidity stack.

Sunrise said QNT is now available on Solana through its infrastructure, with Raydium also highlighting QNT trading on the network. The move gives Solana users a native venue path to the asset without requiring Quant to replace its existing Ethereum presence.

That distinction is important because cross-chain deployments are often described as migrations when they are really expansions.

Solana adds another established asset to its DeFi layer

Raydium is one of Solana’s core decentralized trading venues, so the addition gives QNT a route into a much more active onchain market than a simple wallet integration would provide.

For Quant, the appeal is distribution. QNT has historically been associated with interoperability infrastructure and enterprise connectivity, while Solana has become one of the most liquid retail and payments-focused blockchain environments.

Putting the token into that market can widen access even if nothing changes about Quant’s underlying network architecture.

Solana’s financial role has already been broadening beyond exchange trading. Toss Bank has tested Solana stablecoin rails for overseas transfers, while regulated payment companies are increasingly choosing fast public chains for settlement. That is very different from a speculative token listing, even though both developments use the same liquidity infrastructure.

Cross-chain access is becoming a distribution strategy

Token projects used to treat one blockchain as a permanent home. That model is weakening.

Liquidity now sits across Ethereum, Solana, Base and other networks, while users expect assets to follow them rather than forcing every trader onto the same chain. Bridges, custody providers and tokenisation platforms increasingly act as distribution layers between those ecosystems.

That trend is also visible in institutional markets. NewsBTC has covered how Visa is expanding stablecoin settlement infrastructure and how Circle’s EURC moved natively onto Base.

QNT’s Solana expansion is smaller in scale, but it belongs to the same structural shift: assets are becoming less tied to one execution environment.

Liquidity is the next test

A listing is only the start.

The practical question is whether enough QNT liquidity develops on Solana to make the route useful beyond headline visibility. Thin pools can technically support an asset while still producing poor execution for meaningful trades.

For now, the confirmed event is straightforward. QNT has a new Solana access point through Sunrise and Raydium, extending the token’s reach into another major blockchain market without replacing its existing footprint.
