#openledger $OPEN 💥Echo Protocol, a DeFi platform centered on Bitcoin, acknowledged a significant hack on May 19, 2026🔥
👍Following an attacker's acquisition of an administrative private key on the Monad blockchain. Using this access, the attacker minted around 1,000 unbacked eBTC tokens with a notional worth of roughly $76.7 million at the moment.
💥The Mechanism of the Echo Protocol Assault
🔥 Initial Breach and Token Minting: The attacker created about 1,000 eBTC tokens following the first breach. 45 eBTC (worth around $3.45 million) of these were put up as collateral on the Curvance platform to borrow 11.3 WBTC (worth about $868,000). The attacker then transferred the stolen WBTC to Ethereum and washed the money using Tornado Cash.
🔥Swift Protocol Response: The Echo team stopped all cross-chain transfers right away to limit the damage and confirmed they had recovered control of the compromised admin key. To stop more misuse, they then burned the 955 eBTC remaining in the attacker's wallet.
🔥Right After & Here are the steps: Following the news, the ECHO token of the platform dropped more than 12%. As a precaution, Curvance stopped the damaged market; both the Monad and Aptos networks were stated to be functioning normally. Echo has stopped and updated the pertinent contracts as part of an effort to restore operations, while the inquiry goes on.
💎 The Expanding Threat Scene in Decentralized Finance
👍The Echo Protocol event draws attention to a disturbing tendency in the DeFi sector whereby an operational security breakdown, such the compromise of a single admin key, was the underlying cause instead of a flaw in a smart contract. In May 2026 alone, this hack was the 14th major cryptocurrency exploit documented following other notable violations at THORChain and the Verus-Ethereum
