- DeFi coalition backs Illinois crypto-tax lawsuit as rules draw scrutiny — this brief
A coalition of DeFi builders led by 
Uniswap, Andreessen Horowitz and Paradigm has filed a court brief supporting the crypto industry’s lawsuit against Illinois’s digital asset tax. Cryptopolitan reports that the proposed rate is 0.2%, placing the dispute squarely over how the state intends to collect taxes from digital-asset transactions.
The coalition’s intervention brings major decentralized-finance participants directly into the legal fight. Cryptopolitan says Illinois’ draft rules could characterize fee-charging decentralized exchanges and their frontends as tax-collecting brokers, while Cointelegraph highlights a separate concern: the tax applies even when a transaction produces no profit.
Both outlets corroborate the industry’s legal challenge and the importance of the court filings, though they emphasize different risks. Cryptopolitan focuses on the proposed broker treatment of DEXs and frontends; Cointelegraph discusses compliance burdens and the argument that the tax may violate federal law.
The matter concerns the mechanics of taxing a sector built around automated exchanges, liquidity pools and interfaces operated across different participants. The proposed rules could therefore affect more than the tax treatment of individual transactions by determining which parts of the DeFi stack may be treated as collection points.
Market data show a broadly weaker backdrop: 
Bitcoin fell 3.94% over 24 hours, the Fear & Greed index stood at 28, or Fear, and the total crypto market capitalization was $2.46 trillion. UNI traded at $6, down 7.59% over 24 hours and 12.04% over seven days, while DeFiLlama reported Uniswap TVL of $3.33 billion, down 5.9% over seven days. The legal arguments and final form of Illinois’ rules remain the developments to monitor.
Since this brief published about 3 hours ago, Uniswap (UNI) has moved from $6.00 to $6.02 — +0.33%.
The chart plots UNI's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from TLT's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Not financial advice.
At today's peer-to-peer rate, 1 UNI ≈ ₦8,467.01 (about $6.02), down 3.6% over 24 hours. The naira itself trades about 4.2% above the official rate on the P2P market, so a Nigerian buyer's effective cost differs from the headline dollar price.
