Neutrl has suspended minting, redemptions and other protocol functions for its NUSD synthetic dollar after unspecified circumstances affected protocol reserves, and it said the freeze was taken on legal advice while it assesses the impact. The protocol has not identified the affected asset or counterparty, said whether reserves suffered a realized loss or given a timeline for resuming operations, leaving solvency, liquidity and off-chain exposure questions unresolved. The pause comes with about $53.6 million of NUSD still in circulation, down roughly 76% from the $226 million supply level documented by BA Labs in February. RWA.xyz showed NUSD supply down 18.4% over the past 30 days, monthly transfer volume down 72.4% to $71.4 million and the token trading near its intended dollar value at about $0.9984, though the available data does not establish that the earlier contraction was caused by the reserve issue disclosed this week. RWA.xyz also recorded 615 holders and 347 active addresses over the preceding 30 days. Strata later paused minting, redemptions and related functions for contracts in its Neutrl market while keeping its other markets open. NUSD is designed to track the U.S. dollar using yield-bearing crypto assets and market-neutral strategies rather than bank deposits or short-term government securities, a structure that can leave reserves spread across custodians, trading venues and investment strategies. The latest disclosure adds to earlier scrutiny of Neutrl's reserve transparency and risk profile: Accountable said on May 25 that its dashboard provided continuous cryptographic proof that reserves matched liabilities, while a February BA Labs review still classified a proposed integration as higher risk and estimated $233.7 million in reserves against $226 million of NUSD, or about 103.6% collateralization, with more than 87% of reserves held through Fireblocks.
