Tessera DAO Hack

BNB Chain
Access Control

What happened

On June 1, 2026, the TesseraDAO protocol on BNB Chain was drained by whoever controlled its admin key. That key still held unrevoked authority over role assignment, ownership, minting and withdrawals. The holder minted 99 million TSR, converted them into about 2.48 million BSC-USD (USDT), and withdrew the stablecoins. TSR fell about 99%. The proceeds were bridged to Ethereum, and 1,285.5 ETH went through Tornado Cash. Public sources do not establish whether the key was stolen or used by an insider. TesseraDAO had issued no statement by June 2, and Rekt reported that its first post after the drain did not mention the exploit.

Attacker wallet: 0x2201037A1755eC48eC5f00Fea21A10A9E56f2Dd8 Mint transaction (BSC): 0x25093e573c116562c8839dc67a15ac21761271006a8dfe50b18fa475564bfcd1

How it happened

  1. The admin key 0x61a23e0eba09096ffeb954aa8a93c3079e87cf17 called reassignRole() on the TesseraDAO contract, moving the trader and withdrawer roles to the attacker wallet 0x2201...2Dd8 (tx 0xa748067f...d79d721).
  2. A transferOwnership() call then gave the attacker ownership of the contract (tx 0xf799e7b0...af7d2453).
  3. The attacker minted 99 million TSR from the zero address (tx 0x25093e57...5564bfcd1).
  4. The minted TSR was converted into 2,475,659 BSC-USD through the protocol's own trade() function (tx 0x756d33e7...d88c9bb).
  5. Two withdrawal transactions moved the stablecoins out. The funds were bridged to Ethereum, and 1,285.5 ETH was deposited into Tornado Cash.
