THEO Token Plunges 92% After Attacker Mints 19 Million Tokens and Converts Them Into $1.76 Million in ETH
Key Takeaways
- •An attacker minted 19 million THEO tokens on the Base, according to data from blockchain security firm PeckShield.
- •The freshly minted tokens were sold on the open market for 700.8 ETH, valued at approximately $1.76 million, and the proceeds were subsequently transferred from Base to the Ethereum mainnet.
- •THEO's price fell roughly 92% in 24 hours as the unauthorized token influx diluted existing holders' positions and drained market liquidity.
- •It remains undetermined whether the exploit originated from a flaw in the token contract or compromised administrative keys, and whether the total loss exceeds the estimated $1.76 million.
- •Base is an Ethereum Layer-2 network developed with support from Coinbase, built to offer lower transaction fees while settling activity to the Ethereum mainnet.
THEO, a digital asset operating on the Base network, has suffered one of the steepest declines in its trading history following a suspicious large-scale token minting incident. Base is an Ethereum Layer-2 network developed with support from Coinbase, built to offer lower transaction fees while settling activity to the Ethereum mainnet.
According to data shared by PeckShield, a blockchain security and analytics firm that monitors on-chain exploits, the attacker generated 19 million THEO on the Base network. Incidents of this kind typically involve an unauthorized party minting new tokens without permission, instantly expanding the supply far beyond what existing holders originally purchased into.
The freshly minted tokens were then sold on the open market, converting them into 700.8 $ETH. At the prices prevailing during the transaction, the Ethereum obtained was valued at approximately $1.76 million. It was reported that the attacker subsequently transferred the acquired $ETH from the Base network to the Ethereum mainnet. Tracing funds as they move between networks is a standard part of post-incident analysis by on-chain security firms, since cross-chain transfers determine where the proceeds ultimately reside.
The selling pressure had an immediate impact on the market. The price of THEO fell by approximately 92% over the last 24 hours, and the sudden influx of permissionlessly minted tokens into circulation rapidly diluted existing investors' holdings while causing a significant drain on market liquidity.
While initial data suggests the incident was an attack, several key questions remain unanswered. It is not yet clear which contract the vulnerability originated from, whether private keys were compromised, and whether the total loss is limited to the estimated $1.76 million. Each possibility points to a different type of weakness — a flaw in the token contract itself versus compromised administrative control — which is why pinning down the entry point matters for the post-mortem. Updated figures from security firms or a public statement from the project behind THEO would clarify the full scope of what occurred.
