Cardano's Optim Finance Protocol Reports OADA Pool Hack
The Optim Finance protocol on Cardano reported a hack of its OADA pool. Initially, the team claimed the damage was limited to the OADA pool balances, but it was later revealed that hackers drained all other related platforms, effectively wiping out the entire volume of ADA-pegged assets and leaving no liquidity in any OADA pool. The protocol team recommended that all providers of OADA liquidity or holders of the governance token O withdraw their funds immediately.
The exact damage was not disclosed. According to DefiLlama, the total value locked (TVL) on Splash was around $3.3 million on September 13, while Cardano's overall DeFi TVL stood at $55 million. CoinGecko data shows the OADA supply is just over 4 million tokens.
OADA is a synthetic asset by Optim Finance, pegged to the Cardano cryptocurrency price. Users mint it in a 1:1 ratio with ADA, with staking rewards recorded in a separate token, sOADA, not directly in OADA. There is no direct path to redeem OADA back to ADA; the only documented method is swapping through the OADA/ADA pool on Splash. It remains unclear if sOADA holders will incur losses.
Separately, the Cardano-based DeFi platform Empowa recently reported unauthorized token transfers from three of its crypto addresses, believed to be due to compromised private keys. One incident involved its ADA treasury wallet, from which 143,710 ADA were withdrawn between November 2025 and June 2026.
