TAC token crashes 80% in one session, two months after white hat hack

TAC Protocol’s token fell about 82% in 24 hours to around $0.0056, wiping out most of its market value two months after a $2.8 million bridge hack, that the team reclassified as a white-hat incident.

The token last traded at $0.005596, down 81.8% on the day, with its market cap also down to about $26.2 million. TAC hit an intraday high of $0.05285 and a low of $0.005103. Trading volume hit $66.6 million over the same period, over ten times the level from the previous day, a sure sign of heavy turnover.

The slide cut whatever gains TAC made in recent times. It had set a record of $0.06688 on June 30, roughly a week before the crash. At current prices, the token trades about 92% under that peak.

TAC’s claim to fame is that it is the first EVM-compatible blockchain built for the TON ecosystem and Telegram. TAC launched its mainnet and native token in July 2025, with protocols like Morpho, Curve, and Euler deployed at go-live. And an $800 million liquidity campaign to go with it.

TAC is back in the headlines for the wrong reasons

The price rout drags attention back to a difficult spring. On May 11, an attacker carted away with $2.8 million from the TON side of TAC’s cross-chain bridge, hitting balances in USDT, BLUM, and tsTON, per Cryptopolitan’s earlier reporting. TAC halted the bridge and said its native token and ERC-20 assets were not touched.

By May 15, the team had positive news, reporting that the attacker had returned ~ 90% of the funds in a deal that allowed them to keep 10% of the loot.

As TAC proposed, it then dropped any plans of going to court and simply cast the event as a white-hat event, a decision it said it coordinated with security partners and law enforcement.

The bridge itself remained dark for weeks. TAC restored cross-chain transfers between TON and TAC on June 10 after it ensured its patched sequencer software had cleared an independent review by its auditor and TON ecosystem partners.

The team’s own disclosures also conceded that the fix produced 316 duplicate transactions.

Days before this week’s collapse, TAC pushed a network change. It told node operators on June 29 to install a v1.6.0 binary ahead of a June 30 upgrade at block 21,776,800.

No explanation or rationale for the selloff has been presented as of this report.

Readers holding TAC or building on the chain should keep an eye on the project’s X account for a statement on the crash and any follow-up on the June 30 upgrade.
