Taiko's native token, TAIKO, has dropped to a fresh all-time low following a security breach that drained approximately $1.7 million from the Ethereum-based rollup's bridge. The token fell 11% in the past 24 hours, underperforming the broader crypto market as the incident unfolded.
Exploit Details and Network Response
On June 22, 2026, Taiko confirmed a compromise of its chain state verification mechanism, which allowed attackers to forge withdrawal proofs. The protocol stated that all bridges deployed on Taiko should no longer be considered secure and advised users to immediately withdraw funds. Centralized exchanges were also urged to suspend deposits of TAIKO until further notice.
Taiko's team, in coordination with its Security Council and ecosystem partners, paused affected systems and temporarily halted block production to investigate. By 2:08 a.m. ET, the exploit was contained, and withdrawals via the L1 Bridge and ERC20Vault were fully stopped to prevent further losses.
Vulnerability and Losses
According to Taiko's investigation, the attack exploited a flaw in the bridge message-proof verification system. Forged message proofs were incorrectly accepted on Ethereum Layer 1 without a valid corresponding event on the source chain, enabling the attacker to register fake withdrawals and extract funds from the bridge and token vault. On-chain security firm Blockaid identified the same vulnerability, noting that malicious message proofs were accepted as valid without matching 'MessageSent' events on the Taiko chain.
Initial loss estimates from Blockaid were around $1 million, but PeckShield later revised the figure to approximately $1.7 million. PeckShield also reported that the attacker moved roughly 1.99 million TAIKO tokens (worth about $169,702) to an address linked to the MEXC exchange. Taiko has confirmed the $1.7 million estimate and is preparing a full post-mortem report.
Market Impact and Technical Outlook
The TAIKO/USD 4-hour chart shows a bearish trend, with momentum indicators pointing to further downside. The Relative Strength Index (RSI) at 32 suggests the token is approaching oversold territory, while the Moving Average Convergence Divergence (MACD) lines remain in negative territory. If the bearish trend persists, TAIKO could drop below $0.070, setting a new all-time low. A daily close below this level might extend the decline toward $0.060.
Conversely, a potential bounce could see TAIKO reclaim the $0.082 efficiency level in the short term, with an extended rally targeting the Sunday high of $0.098. However, the immediate outlook remains cautious given the security incident and market sentiment.
Broader Context
The exploit adds to a series of security incidents in the crypto space, highlighting ongoing risks in cross-chain bridge protocols. For context, similar vulnerabilities have led to significant losses in other projects, such as the $230 million USDC movement during the Drift Protocol exploit. Meanwhile, market uncertainty has also impacted other tokens, as seen with Cardano dropping 11% despite whale accumulation.
Investors should monitor Taiko's post-mortem report and any further updates on fund recovery or network security enhancements. The incident underscores the importance of rigorous smart contract audits and real-time monitoring for DeFi protocols.
