November 2025: Stream Finance xUSD and Elixir deUSD collapse.
outcome unclear- What happened. Stream Finance disclosed losses, and its xUSD stablecoin depegged. Elixir's deUSD, which had lent heavily to Stream, followed. MEV Capital said it had Stream-linked exposure on four lending markets and one vault across three L2 networks, with about $34 million "impacted" 10.
- Depositor losses. Per MEV Capital's own posts, as reported by Protos, its Ethereum USDC vault took a 3.5% haircut and its Arbitrum USDC vault a 12% haircut 11. Another report put the Ethereum vault's bad debt at about 3.6% after the sdeUSD/USDC market was removed 12. On Arbitrum, the Arbitrum Foundation recorded about $700,000 of bad debt in the MEV Capital USDC vault and stopped ARB incentive rewards for it 13.
- Legacy deUSD vault. The Elixir USDC vault was launched in 2024 to lend USDC against deUSD, partly through a market with a hardcoded 1:1 price feed 14. Elixir later retired deUSD and opened a USDC compensation process 12. On October 23, 2026, Morpho's API still showed about $1.9 million in this vault, all supplied to a deUSD-collateral market 7.
- Verdict. Losses were realized and passed to depositors in at least two vaults. No full recovery has been documented.
