Iron Finance (TITAN)
A partially collateralized stablecoin protocol on Polygon whose share token TITAN collapsed from ~$64 to near zero on June 16, 2021 in what the team called crypto's 'first large-scale bank run.' Its TVL fell from ~$2B; investor Mark Cuban said he was among those hit.
Also known as: Iron Finance, TITAN, IRON
Summary
Iron Finance ran a partially collateralized stablecoin (IRON) on Polygon and Binance Smart Chain, backed by USDC and its own share token, TITAN. On June 16, 2021, large holders sold TITAN, IRON lost its dollar peg, and a feedback loop in the redemption mechanism drove TITAN from about $64 to effectively zero within hours; the protocol's value fell from roughly $2 billion. [1][2]
Mechanism and aftermath
The team's post-mortem described "the world's first large-scale crypto bank run": as panicked users redeemed IRON, newly minted TITAN flooded the market and a time-weighted price oracle widened the gap between spot and redemption prices, accelerating the collapse. The episode drew extra attention because billionaire Mark Cuban had praised the protocol days earlier and said he was hit; he subsequently called for stablecoin regulation. A U.S. Federal Reserve note later studied the run. [1][2][3]
