Some notable crypto hacks in 2022:
- January 7, 2022: Vitalik Buterin warns of the insecurity of bridges (bridges) on Reddit
- January 29: Qubit bridge was hacked for 15.7k ETH, 767 BTC and $9.5m worth of stablecoins.
- February 2: Wormhole bridge was hacked for 93,000 ETH.
- March 23: Ronin’s bridge hacked for 174k ETH and 25.5M USDC

Sam Peurifoy, director of interaction at Hivemind Capital, said bridges now represent the greatest risk of failure of the cryptocurrency sector!
According to statistics from Dune Analytics, Ethereum bridges have over $21 billion locked up.
Wormhole, a bridge connecting Ethereum to the Solana blockchain, was the victim of a $300 million hack. The Meter Passport bridge was compromised the same month, losing several million dollars in cryptocurrencies.
Bridges have also proven to be vulnerable to other factors besides hacking. Celo Network’s Optics bridge became unusable last year after the bridge’s development team lost control of the project.
It is sometimes difficult to know who built or who manages a bridge. The identity of validators may be voluntarily kept secret, and developers are free to remain anonymous.
Many bridges are operated by companies with few security personnel according to Bloomberg. It can take several days before a problem is even identified. The Ronin hack, which cost over $600 million altogether, took place on March 23, but wasn’t discovered until March 29.

Blockchain interoperability under threat!
The more the volume of tokens passing through the bridges increases, the more their vulnerability is increased. There was simply the Bitcoin blockchain about 13 years ago. There are already hundreds of blockchains, each with their own advantages and limitations.
Investors must gradually jump from one channel to another to do yield farming or acquire NFTs.

For example, someone with Ethers may want to migrate them to Solana to buy NFTs.
Investors will continue to switch from one channel to another for various reasons. We can therefore only hope for even more secure bridges managed by reliable players.
