# Yala Protocol Exploited Resulting in Stablecoin De-Peg Event ▴ News

**Published:** 2025-09-15
**Categories:** News

---

The security breach of the Yala protocol represents a critical failure within its core architecture, specifically at the cross-chain bridge connecting Polygon, Ethereum, and Solana. This bridge, designed to facilitate interoperability, became the primary [attack surface](https://prime.greeks.live/area/attack-surface/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), allowing for the unauthorized minting of 120 million YU tokens. The systemic implication is a severe loss of confidence in the protocol’s ability to maintain its foundational promise ▴ a stable $1.00 peg for its Bitcoin-backed YU stablecoin.

The immediate consequence is a [liquidity crisis](https://prime.greeks.live/area/liquidity-crisis/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), as the protocol’s available USDC reserves of $784,000 are insufficient to defend the peg against the newly created supply, rendering the stablecoin’s market cap illusory. This event demonstrates how vulnerabilities in cross-chain communication systems can cascade into catastrophic failures for the financial primitives they are meant to support.

The exploit reveals that the architectural integrity of cross-chain bridges is a single point of failure that determines the viability of any stablecoin system built upon it.

- 
**Unauthorized Minting** ▴ 120 million YU tokens were created without authorization on the Polygon network.

- 
**Value Drained** ▴ $7.7 million was drained from the protocol and converted into USDC stablecoins.

- 
**Peg Collapse** ▴ The YU stablecoin crashed from its $1.00 peg to a low of $0.20 following the attack.
