Nomic Software Bug Left Osmosis’ Alloyed BTC With a 36% Backing Shortfall

A software flaw linked to Nomic quietly reduced the backing of Osmosis’ Alloyed BTC product by approximately 36%, with the issue reportedly remaining undetected for 74 days.

Bug Created a Gap in Bitcoin-Linked Reserves

According to Osmosis, the decentralized exchange’s infrastructure was affected by a flaw that caused a significant discrepancy between the assets backing Alloyed BTC and the amount represented by the token.

Alloyed BTC is a tokenized product on Osmosis that combines several bitcoin-linked assets into a single representation. The software issue meant that a portion of the expected backing was missing, creating what the platform described as a 36% shortfall.

Issue Went Undetected for More Than Two Months

The flaw reportedly remained unnoticed for 74 days. The delay highlights the difficulty of monitoring cross-chain systems and tokenized assets, particularly when reserve calculations depend on multiple protocols and software components.

Unlike a conventional exchange-traded product with centralized reporting, decentralized finance systems often rely on smart contracts, bridges and automated accounting mechanisms. An error in any of those components can affect how collateral levels are recorded or displayed.

Broader Risks for Cross-Chain DeFi Systems

The incident adds to a growing list of vulnerabilities involving decentralized applications, bridges and tokenized assets. Bugs in these systems can lead to accounting discrepancies even when there is no immediate exploit or visible disruption to users.

Osmosis’ disclosure underscores the importance of independent reserve verification, continuous monitoring and timely detection mechanisms for crypto products that claim to be backed by other assets.
