Main Street’s msUSD stablecoin lost more than 70% of its peg over the weekend of June 20-21. The crash came after Accountable, its proof-of-solvency provider, abruptly ended its service agreement, saying Main Street failed to meet its verification standards.
Accountable acts as an independent verification layer. It confirms whether a protocol’s reserves match its liabilities. When it pulled out, market confidence in related protocols collapsed fast.

Altura used the same Accountable verification service. Even though it had zero direct exposure to msUSD or Main Street’s strategies, users didn’t wait around to find out the details.
More than $8.5M in USDT was redeemed from Altura’s vault within a single 24-hour window. That’s roughly 22% of the vault’s total value locked, gone overnight.
Altura’s vault followed the ERC-4626 standard. Users deposited USDT and received vault shares. The protocol deployed those funds across funding-rate arbitrage, market making, and real-world asset positions.
Users had two withdrawal options. They could exit instantly for a 0.1% fee, or wait for an epoch-based withdrawal at no cost.
CEO Ranveer Arora announced the wind-down on June 21 via X. He said the decision was made to protect user capital and ensure redemptions happen in a fair and orderly way, rather than let a bank-run scenario spiral.
Arora expressed frustration over what he called unfounded narratives driving panic. He said Altura has always operated with transparency and that the withdrawal pressure was fueled by speculation rather than facts.
Altura’s official account had already published a statement clarifying it had no direct exposure to Main Street or msUSD before Arora’s personal post went out.
Counterparties and partners were notified of the wind-down decision. Altura began unwinding positions held on exchanges, in private credit, and in real-world asset strategies. Some positions may take longer to fully redeem, the company said.
Altura’s other products, including its HyperEVM lending vault and Ethereum vault, continue to operate normally and were not part of the wind-down.
The Accountable situation exposed a structural vulnerability. Protocols that rely on a single external entity for solvency verification carry a concentrated risk that can trigger user panic even when their own finances are sound.
