Yala’s over-collateralized Bitcoin-backed stablecoin YU has lost its peg to the U.S. dollar after a reported exploit attempt. On Sunday morning, YU’s price dropped sharply, reaching $0.2046 at one point. Yala’s team confirmed in an official statement:
“All funds are safe. Bitcoin deposits remain either self-custodied or stored in vaults. No funds were lost.”
What Happened:
The attacker managed to mint nearly 120 million YU on the Polygon network, then bridged and sold around 7.7 million YU for USDC across Ethereum and Solana. The USDC was subsequently converted to ETH and distributed across multiple wallets. Currently, the attacker still holds 22.29 million YU on Ethereum and Solana, along with another 90 million YU on Polygon that has not yet been bridged.
YU Stablecoin and Market Situation:
YU was originally designed to hold a dollar peg, with an estimated $119 million market capitalization before the attack. However, liquidity was relatively thin—Ethereum pools had only about $340,000 worth of USDC backing YU trades. After the depeg, YU briefly recovered to $0.917, but quickly dropped again and is now trading near $0.7869.
Yala Team’s Response:
Yala has engaged blockchain security firm SlowMist and other partners to investigate the exploit. The protocol has temporarily suspended “Convert” and “Bridge” features to prevent further risks. Other protocol functions remain active, with Yala assuring users that assets remain secure.
Potential Impact and Next Steps:
The incident raises serious concerns over the reliability of Yala’s stablecoin, which depends on maintaining a steady peg to the U.S. dollar. Losing that stability undermines its core purpose.
Key factors to watch moving forward:
- Investigation Results – Whether a security loophole was exploited and if any funds were permanently lost.
- Enhanced Security Measures – Improvements in auditing and safeguards to prevent future attacks.
- Market Confidence – Whether users and investors regain trust, and if YU can successfully re-establish its dollar peg.
YU stablecoin has faced a major security crisis, dropping far below its intended $1 peg after an attacker minted millions of tokens. While Yala insists that no funds have been lost and is working on security fixes, restoring user confidence and stabilizing YU’s price may prove to be a long and difficult road.
