Here's what happened in crypto today: FASB and Maya hack
Here's what happened in crypto today: US accounting rulemakers proposed strict conditions for stablecoins as cash equivalents, cross-chain DEX Maya Protocol halted after a roughly $1.7 million exploit sent CACAO down nearly 89%, and South Korea ordered Polymarket blocked over gambling concerns. Bitcoin traded near $64,000 as regulation, DeFi security, and corporate treasury moves shaped the session.
Key Takeaways
- FASB proposed guidance on when companies may treat qualifying stablecoins as cash equivalents under US GAAP.
- Maya Protocol halted swaps after six chained bugs enabled an estimated $1.7M exploit and an 88.7% CACAO crash.
- Metaplanet plans a US Bitcoin treasury arm via a 2,100 BTC deal with Nasdaq-listed Super League Enterprise.
- South Korea's media regulator ordered Polymarket access blocked, citing illegal gambling under national law.
Why did Maya Protocol halt its network?
Cross-chain decentralized exchange Maya Protocol stopped operations after an attacker exploited a chain of software flaws to drain an estimated $1.7 million in crypto. Co-founder Aalux said the attacker stole about 20 Bitcoin, valued at $1.4 million, plus roughly $300,000 in other assets.
A preliminary technical analysis attributed the breach to six chained bugs involving trade accounts, outbound transaction handling, and liquidity pool calculations. The attacker used a single transaction containing 23 messages to trigger false theft detection, inflate a low-liquidity pool, and withdraw 48.87 million CACAO tokens from Maya's Asgard module.
Independent researcher Vini Barbosa noted CACAO fell 88.7%, from about $0.115 to $0.013 during the incident. Maya implemented a global halt, contained further damage, and began work on a fix to resume swaps, according to Cointelegraph's report.
Can stablecoins count as cash under US accounting rules?
The Financial Accounting Standards Board (FASB) proposed guidance Tuesday outlining when companies may classify certain stablecoins as cash equivalents under US generally accepted accounting principles. The proposed Accounting Standards Update would add illustrative examples without changing the underlying definition.
Qualifying digital assets would need an on-demand contractual redemption right, a direct issuer redemption right for a known cash amount, and at least one-to-one segregated reserves in short-term, highly liquid assets. Active secondary-market liquidity alone would not qualify a token if the holder lacks direct issuer redemption rights.
Reserves made up of crypto assets and gold would also disqualify a token because of valuation risks. FASB is accepting public comments until Nov. 19 and will set an effective date after reviewing feedback. For more daily coverage, see our Fintech & Crypto Alerts hub.
What else shaped crypto headlines today?
Tokyo-listed Metaplanet unveiled plans to extend its Bitcoin treasury strategy into the United States through a deal involving 2,100 BTC. The company would take a controlling stake in Nasdaq-listed Super League Enterprise, set to be renamed Superplanet, using Bitcoin from its existing 43,000 BTC holdings rather than a new purchase.
CEO Simon Gerovich said the structure could give the group access to capital markets in both the US and Japan. The transaction is expected to close in the fourth quarter of 2026, subject to shareholder approval. Super League shares jumped more than 50% after the announcement.
Meanwhile, South Korean authorities ordered access to Polymarket blocked after determining the crypto prediction market provides an illegal gambling environment. The media and communications review commission cited winner-takes-all markets on politics, sports, and weather, rejecting Polymarket's arguments about decentralization and the removal of Korean-language services.
