Yala’s Bitcoin-Backed YU Stablecoin Struggles to Recover After Reported Exploit

The YU stablecoin issued by Yala, a Bitcoin-collateralized project, is facing mounting uncertainty after losing its dollar peg during what the team described as an attempted protocol attack. The token, which is designed to maintain parity with the U.S. dollar, plunged to $0.2046 and has yet to return to stable levels, raising fresh concerns about the fragility of new entrants in the expanding stablecoin sector.

According to blockchain analytics firm Lookonchain, the exploit began when an attacker minted 120 million YU on Polygon. From there, approximately 7.71 million YU were bridged and swapped for around 7.7 million USDC across Ethereum and Solana, before being converted into 1,501 ETH and spread across several wallets. While large amounts of YU remain on multiple chains, the sudden supply shock caused an immediate collapse in the token’s market value.

The Yala team has sought to reassure users that no collateral reserves were compromised, stressing that Bitcoin backing the protocol remains either self-custodial or secured in vaults. In a statement, the project confirmed that “all funds are safe,” but acknowledged that features such as Convert and Bridge have been paused as a precaution while security partners, including blockchain security firm SlowMist, conduct an investigation. Other functions of the protocol remain active, though users have been advised to wait for official updates before resuming normal activity.

The incident exposes a deeper structural problem: the mismatch between YU’s circulating supply and available liquidity. Data from DEX Screener indicates that the Ethereum pool supporting YU contained only about $340,000 in USDC liquidity at the time of the attack, compared with a reported $119 million market capitalization. This imbalance amplified slippage when large volumes of YU were sold, accelerating the loss of its peg and leaving little immediate capacity for recovery.

While the attacker did not directly drain collateral reserves, the unauthorized minting of new tokens created a confidence crisis. With liquidity gaps magnifying price swings, holders now face uncertainty over whether the stablecoin can reestablish its dollar parity. Yala’s ongoing efforts to restore the peg include halting key features and coordinating with exchanges and analytics firms, but no clear timeline for full recovery has been offered.

The disruption comes as the stablecoin market approaches a $300 billion milestone, led by established issuers such as Tether’s USDT and Circle’s USDC, alongside emerging yield-bearing alternatives like USDe. In this context, the YU incident underscores the vulnerabilities that can arise when new protocols scale supply without securing sufficient market depth to defend their peg.

For now, YU holders are urged to avoid using paused services until Yala confirms their safety. Market watchers warn that restoring confidence may prove more difficult than technical fixes, as investors weigh the risks of holding a token that has already deviated so dramatically from its intended value. The episode serves as a cautionary reminder of the operational and liquidity challenges facing experimental Bitcoin-backed stablecoins in an increasingly crowded sector.
