DeFi protocol Neutrl said Thursday it has paused minting and redemptions for its synthetic dollar NUSD after what it described as unspecified circumstances affecting protocol reserves. The protocol also suspended other functions after advice from legal counsel and said it is assessing the extent of the impact on reserves.
Neutrl did not identify the affected assets or counterparties. It also did not say whether the reserves had already incurred realized losses, and it gave no timeline for resuming operations.
Neutrl and Strata suspend related functions

Structured yield protocol Strata later said on X that it had also paused minting, redemptions, and other functions for contracts related to its Neutrl market. Strata said its other markets remain operational.
About 53.6 million NUSD are currently in circulation. With redemptions paused, approved counterparties cannot temporarily exchange the token back into its reserve assets. Neutrl said it will publish a timeline for resumption and outline next steps once it has more clarity.
NUSD supply and activity have both contracted
According to on-chain asset data platform RWA.xyz, NUSD had a market value of about $53.6 million as of Friday, down 18.4% over the previous 30 days. Monthly transfer volume over the same period fell 72.4% to around $71.4 million.
The data does not establish a direct link between that earlier contraction in supply and the reserve issue now disclosed by the protocol.
NUSD is a synthetic dollar designed to track the U.S. dollar using yield-bearing crypto assets and market-neutral strategies rather than traditional bank deposits. Data cited in the report showed NUSD trading around $0.9984, with 615 holders and 347 active addresses over the past 30 days.
The report cited RWA.xyz and a February risk assessment from BA Labs as sources for those figures.
Accountable had described reserves as matching liabilities in May
An earlier statement had suggested a stronger reserve position. On May 25, verification platform Accountable said its Neutrl dashboard provided continuous cryptographic proof showing that NUSD reserves matched protocol liabilities. That meant the protocol was still presenting its reserve position as sound less than three months ago.
BA Labs had flagged the integration as higher risk in February
In a February assessment, risk advisory team BA Labs classified the Neutrl integration proposal as higher risk, citing counterparty, operational, and liquidity exposure.
BA Labs said direct NUSD redemptions were available only to counterparties that had passed KYC or KYB checks. It added that redemption requests exceeding the liquidity buffer could be queued, with a target of completion within 48 hours but no guarantee.
At the time, BA Labs estimated NUSD supply at about $226 million and reserves at about $233.7 million, implying a collateralization ratio of 103.6%. More than 87% of reserves were held in custody through Fireblocks, with the rest spread across centralized exchanges.
Key details on reserve impairment remain undisclosed
The lack of disclosure around the affected assets and the absence of a recovery timeline have made it difficult to judge the scale of any damage to NUSD.
The original report also pointed to prior cases where stablecoin issuers paused redemptions after reserve questions surfaced. It cited Prime Trust, a service provider for TrueUSD, which faced regulatory intervention in 2023 over insolvency and suspended deposits and withdrawals, as well as Near-native stablecoin USN, which was wound down after collateral shortfalls.
