dTRINITY Hack
What happened
On March 17, 2026, dTRINITY's Ethereum dLEND market incurred approximately $257,000 in dUSD bad debt through a liquidity-index inflation exploit. dTRINITY reports that the bad debt was fully covered.
An accounting edge case inherited from the Aave V3 fork let flash-loan fees disproportionately inflate liquidityIndex when the cbBTC reserve was effectively empty. The resulting precision and accounting distortion overstated collateral value.
How it happened
The attacker targeted an almost-empty cbBTC reserve and repeatedly used flash-loan premium accrual to inflate its liquidity index. The distorted accounting overstated collateral value, allowing the attacker to borrow dUSD before recovering the deposited collateral.
