Yala’s Bitcoin-backed YU stablecoin has faced one of its biggest tests after an attempted attack destabilized the protocol and drove its price down to $0.2046, far from its intended $1 peg. Despite partial recovery, YU continues to trade under pressure, raising questions about the resilience of emerging decentralized stablecoin models.
The Incident: Attack on YU Protocol
The Yala team confirmed that the event took place early Sunday, briefly disrupting YU’s stability. They announced via X that all Bitcoin collateral remains safe, stored either self-custodially or within vaults, and emphasized that no user funds were lost.
As a precaution, Yala temporarily disabled Convert and Bridge features to limit further instability. Other functions of the protocol remain operational. Blockchain security firm SlowMist has joined the investigation to identify and resolve the vulnerabilities.
Exploitation Details
Blockchain analytics firm Lookonchain reported that the attacker minted 120 million YU tokens on Polygon, then bridged and sold 7.71 million YU for 7.7 million USDC across Ethereum and Solana.
The attacker then converted the stolen USDC into 1,501 ETH, dispersing the funds across multiple wallets. Current blockchain data suggests:
- 22.29 million YU still held on Ethereum and Solana
- 90 million YU remaining unbridged on Polygon
This liquidity mismatch highlights a critical weakness: YU, despite being overcollateralized with Bitcoin reserves, only had about $340,000 USDC liquidity in its Ethereum pool, leaving it vulnerable to large-scale shocks.
Price Recovery and Current Status
Following the exploit, YU briefly rebounded from its low of $0.2046 to $0.917, but has since failed to restore its peg. At the time of writing, the stablecoin trades around $0.7869, according to DEX Screener.
The project’s market cap stands at $119 million, but investor confidence remains shaky until security patches and liquidity measures are strengthened.
The attack comes at a pivotal time for the broader stablecoin industry. The global stablecoin market is nearing $300 billion, with CoinMarketCap reporting the milestone, while CoinGecko and DefiLlama place the figure closer to $291–289 billion.
Since surpassing $200 billion in late 2024, the sector has grown rapidly. Yet, mainstream adoption remains limited, and incidents like Yala’s raise concerns over trust, liquidity depth, and decentralization risks.
