Terra Luna Classic

LUNC is the token of the original Terra chain, which collapsed in May 2022 when its algorithmic stablecoin lost its peg. Tens of billions of dollars in value were destroyed within days. It remains the most instructive failure in the history of this industry.

The mechanism, and why it could not hold

The stablecoin was backed not by reserves but by the ability to mint the volatile token in exchange for it at a fixed dollar value. When confidence broke, redemptions minted enormous quantities of the volatile token, whose price collapsed under the supply, which triggered more redemptions. The mechanism accelerated the failure rather than arresting it.

The yield that drove the growth

A lending protocol on the chain offered a high fixed return on the stablecoin, subsidised rather than earned. That yield attracted the deposits that made the system large. A subsidised return presented as a savings rate is the specific pattern that turned a design flaw into a systemic event.

Why the failure was foreseeable

Reflexive backing had failed before at smaller scale, and the mechanism was publicly documented. The lesson generalises directly: if a stablecoin's backing consists of an asset whose value depends on confidence in the same system, it has no backing during exactly the conditions that matter.

What LUNC is now

A community-maintained chain continuing after the collapse, with an extremely large supply and burn initiatives aimed at reducing it. Holders should understand they hold the asset of the failed original chain rather than the successor network.

Why it is worth documenting

This event reshaped stablecoin design and regulation across the sector. Several protocols abandoned algorithmic models directly because of it. Understanding what happened here explains much of how the rest of the market is now built.
