The Wormhole token bridge skilled a safety exploit right now, ensuing within the lack of 120,000 wETH tokens ($321 million) from the platform.
Wormhole is a token bridge that enables customers to ship and obtain crypto between Ethereum, Solana, BSC, Polygon, Avalanche, Oasis, and Terra with out using a centralized change (CEX). That is the most important crypto hack of 2022 to this point and the second largest DeFi hack thus far. The Wormhole staff has provided a $10M bug bounty for the return of the funds.
The hack passed off on the Solana facet of the bridge and there are fears Wormhole’s bridge to Terra may very well be equally susceptible.
The Wormhole staff has assured the neighborhood that its ETH provide can be replenished to “guarantee wETH is backed 1:1,” however there is no such thing as a phrase but on the place these funds will come from or when.
The wormhole community was exploited for 120k wETH.
ETH shall be added over the subsequent hours to make sure wETH is backed 1:1. Extra particulars to return shortly.
We’re working to get the community again up rapidly. Thanks on your endurance.

The hack passed off at 6:24pm UTC on Feb. 2. The attacker minted 120,000 wETH (WETH) on Solana, then redeemed 93,750 WETH for ETH price $254 million onto the Ethereum community at 6:28pm UTC. The hacker has since used some funds to purchase SportX (SX), Meta Capital (MCAP), Lastly Usable Crypto Karma (FUCK), and Bored Ape Yacht Membership Token (APE).
No different property or chains served by Wormhole have been reported affected, however smart contract auditing firm Certik stated in a report right now that “It’s doable that Wormhole’s bridge to the Terra blockchain shares the identical vulnerability as their Solana bridge.”
The Wormhole staff contacted the hacker by way of their Ethereum tackle to provided to let the hacker hold $10 million price of funds stolen if the remaining funds are returned.
“That is the Wormhole Deployer: We seen you had been capable of exploit the Solana VAA verification and mint tokens. We’d prefer to give you a whitehat settlement, and current you a bug bounty of $10 million for exploit particulars, and returning the wETH you’ve minted. You may attain out to us at email@example.com”
As of the time of writing, wETH tokens despatched throughout the bridge should not but redeemable whereas the Wormhole staff makes an attempt to repair the exploit.
That is the second good contract exploit on a token bridge in per week. On Jan. 28, Qubit Finance’s QBridge was exploited for $80 million on BSC. Additionally it is harking back to the Poly Network hack final August whereby $610 million in crypto was stolen off the platform. In that case, practically all the funds had been returned by the whitehat hacker.

The frequency of good contract hacks on token bridges serves to validate Vitalik Buterin’s Jan. 7 warning that there are “elementary safety limits of bridges.” The Ethereum co-founder’s admonition was throughout the context of a 51% assault on Ethereum, however his recommendation was well-timed as he identified the overall vulnerability obvious on bridges that ship tokens throughout layer-1 blockchains.
