CryptoTaiko is going through a major crisis after a hack caused around $1.7 million in losses. Ethereum's layer 2 network has halted its block production and is asking users to withdraw their funds from all of its crypto bridges.
In brief
- Taiko stopped his blocks after a major fault.
- The attack caused approximately $1.7 million in losses.
- Users must withdraw their funds from network bridges.
Crypto: Taiko stops its blocks after the attack
Taiko has confirmed a critical flaw in its message verification mechanism. This crypto attack allowed a hacker to submit false proofs on Ethereum and withdraw assets without a legitimate transaction on the source chain. The incident reignites concerns around crypto bridges. Faced with the risk, Taiko contributors stopped the production of new blocks. The crypto protocol has also asked centralized platforms to suspend deposits of its native token until further notice.
Taiko then announced that it had contained the exploitation. Withdrawals through its Layer 1 bridge and ERC-20 vault have been stopped. This measure limits further losses, but it also prevents some users from normally accessing their funds. The attack targeted the system responsible for verifying messages between Taiko and Ethereum. The attacker managed to get false evidence accepted on layer 1, without a corresponding event actually existing on the Taiko network.
These fraudulent messages made it possible to record fictitious withdrawals. The crypto bridge nevertheless considered them valid, then released the assets present in its token vault.
lockaid quickly identified a problem in the validation of the source signal. According to the onchain security company, the system did not properly verify that each message presented on Ethereum came from an authentic transaction recorded on Taiko.
The flaw therefore affects a central element of the network's crypto architecture. It's not just a compromised wallet or a stolen private key. The mechanism designed to differentiate real evidence from falsified evidence has directly failed.
Crypto hack reaches $1.7 million
Blockaid's initial estimates were around $1 million in losses. PeckShield later estimated the stolen amount at nearly $1.7 million. Taiko finally confirmed this estimate in its official communication.
The hacker also transferred approximately 1.99 million TAIKO tokens to an address linked to the MEXC platform. These crypto assets were worth almost $170,000 at the time of the move.
This transfer could help investigators track some of the funds. Centralized platforms sometimes have the ability to freeze reported assets. It is still necessary to intervene before the hacker exchanges them or distributes them between several addresses.
Taiko is now preparing a full analysis piracy. The report must specify the exact origin of the flaw, the components affected and the method used to circumvent the controls. He will also have to explain whether other crypto assets remain exposed.
A shock for Layer 2
Taiko is a rollup based on Ethereum block validators. The mainnet was launched in May 2024 in order to improve the capacity of Ethereum while maintaining strong compatibility with its environment.
But a Layer 2 crypto does not only depend on its block production. Bridges play a vital role in transferring assets between Ethereum and the secondary network. A flaw in these gateways can therefore threaten the entire ecosystem.
This attack joins other incidents that have hit Layer 2 Ethereum. Crypto bridges remain prime targets. They concentrate a lot of funds and use complex validation mechanisms between multiple blockchains.
Taiko must now restore its network, secure its bridges and explain whether the victims will be compensated. The protocol must above all demonstrate that the flaw can no longer be exploited. In a market marked by crypto hacks, a simple technical recovery will not be enough. The priority will be to rebuild trust around the network.
