Funds moved to: 99,000,000 TSR minted and immediately dumped on PancakeSwap → ~$2.4M USDT profit (confirmed @SpecterAnalyst verbatim: 'dumped the tokens for $2.4M'). Proceeds bridged from BNB Chain to Ethereum. 1,285.5 ETH laundered via Tornado Cash (confirmed @PeckShieldAlert June 2 2026). TSR token price crashed -99% (from ~$0.07 to ~$0.0002). No funds recovered. No official response from TesseraDAO team.

Timeline: June 1, 2026 11:38:25 UTC — Attacker (0x2201037A1755eC48eC5f00Fea21A10A9E56f2Dd8) executes mint of 99,000,000 TSR tokens from the zero address (Null: 0x000...000) to address 0x6f2b45B950d1739EF67C76F4106df6d6E84904cB. The mint is executed via the contract's privileged mint function, suggesting the attacker controls the contract owner key or has a backdoor. Block 101683094 on BNB Chain. June 1, 2026 — Immediately following mint: Attacker dumps 99M TSR on PancakeSwap, extracting approximately $2.4M USDT. TSR token price crashes -99% within minutes, from ~$0.07 to ~$0.0002. TSR/USDT market cap on DexScreener collapses from ~$7M to ~$213 USDT. June 1-2, 2026 — Proceeds bridged from BNB Chain to Ethereum. @SpecterAnalyst publishes exploit alert on X: 'A project on BNB Chain, @TesseraDao, has been exploited. The attacker minted 99M $TSR and dumped the tokens for $2.4M. As a result, $TSR plunged 99%. The attacker has already has deposited them into Tornado Cash. Theft address: 0x2201037A1755eC48eC5f00Fea21A10A9E56f2Dd8.' June 2, 2026 — @PeckShieldAlert confirms: '99M $TSR was minted and dumped (-99%)... The exploiter swapped the $TSR for ~2.5M $USDT, bridged the stolen funds to #Ethereum, and has already laundered 1,285.5 $ETH via #TornadoCash.' Note: PeckShield reports $2.5M while Specter reports $2.4M — retained $2.4M as primary figure per Specter (first reporter, confirmed theft address verbatim). Post June 2, 2026 — No statement, post-mortem or communication from TesseraDAO team. Protocol effectively abandoned. Strong community suspicion of insider attack or intentional backdoor given the deployer-controlled mint function. No attribution confirmed by any security firm.
