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, an Ethereum-dependent bridge to the Solana blockchain, has been 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 been shown to be vulnerable to other factors besides hacking. The Celo Network optical bridge became unusable last year after the bridge development team lost control of the project.
It is sometimes difficult to know who has integrated or who manages a bridge. Identity of validators can be 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.
