Issues, Risks, and Limitations of Cross-Chain Bridges
Smart contract vulnerabilities
One of the primary issues with cross-chain bridges is the potential for smart contract vulnerabilities. Since bridges rely heavily on smart contracts to facilitate the transfer of assets between blockchains, any weaknesses in the code can lead to exploits, hacks, or unintended consequences. Additionally, the complexity of the smart contracts involved in cross-chain transactions can make them more challenging to audit and secure.
One of the largest attacks occurred in February 2022, when the cross-chain bridge platform Wormhole was hacked, resulting in the theft of 120,000 wrapped Ethereum tokens worth an estimated $320 million
Another concern with cross-chain bridges is the risk of centralization. Many bridge solutions rely on a limited number of validators or nodes, which can create a single point of failure. If these nodes or validators are compromised or become unresponsive, it can lead to a loss of funds or halt cross-chain transactions entirely.
A notable example is the Poly Network hack in August 2021, where a hacker exploited a vulnerability in the bridge’s centralization, stealing over $600 million in various cryptocurrencies. Although the funds were eventually returned, the incident highlighted the risks associated with centralized cross-chain bridges.
Cross-chain bridges often rely on oracles to provide external data, such as asset prices or other off-chain information. These oracles can be subject to manipulation or errors, which can impact the accuracy and reliability of the data provided to the bridge. This can potentially lead to incorrect valuations, unfair trades, or other negative consequences for users.
In February 2020, bZx, a decentralized lending protocol, was hacked twice in a week, resulting in the loss of around $6 million worth of cryptocurrency. The first attack involved a flaw in the bZx smart contract, which allowed the attacker to manipulate the prices and profit off of a decentralized leveraged trade. The attacker opened a 5x leveraged position on the ETH/BTC pair on bZx’s Fulcrum trading platform and borrowed 5,637 ETH through Kyber’s Uniswap and swapped them for 51 WBTC, causing large slippage. The transaction with which the attacker opened the leveraged trade should have been prevented by safety checks, but those checks did not fire due to a bug in bZx’s smart contract. The second attack occurred through a similar mechanic, and the bZx team used their admin super-keys to pause trading and borrowing on bZx and fixed the underlying bug
Consensus mechanism vulnerabilities
The consensus mechanisms used by cross-chain bridges can also be a source of risk. Bridges that utilize less secure consensus algorithms may be more susceptible to attacks or manipulation. Additionally, a bridge’s consensus mechanism may not be compatible with the native consensus mechanism of the connected blockchains, leading to potential issues with integration and trust.
In June 2022, Inverse Finance suffered a price oracle manipulation exploit that resulted in losses of $5.8 million in tokens. The exploit involved a vulnerability in the project’s YVCrvCrypto pool, where the Inverse price oracle estimated the value of its LP token price based on the balance of current assets within the pool. The attacker manipulated this balance of assets through deposits, swaps, and trades, which allowed them to flash loan and make a profit. This was the second attack on Inverse Finance in 2022, with the first attack occurring in April 2022, where attackers made off with $15.6 million in Ether (ETH), wBTC, Yearn.Finance (YFI), and DOLA. These attacks demonstrate the vulnerability of DeFi protocols to price oracle manipulation exploits and the importance of implementing robust security measures to protect users’ funds
Liquidity is a significant concern for cross-chain bridges, particularly when facilitating transactions between smaller or less popular blockchains. Low liquidity can result in slippage, increased transaction costs, and slow transactions. In some cases, the lack of liquidity on one side of the bridge can lead to imbalanced pools, which can be exploited by arbitrageurs, further draining liquidity from the bridge.
For instance, Thorchain, a decentralized cross-chain liquidity protocol, experienced a series of hacks in July 2021, with attackers taking advantage of low liquidity pools and exploiting vulnerabilities within the system. These incidents led to a temporary shutdown of the network and a loss of millions of dollars. The Harmony bridge hack, which occurred in October 2022, also involved a low liquidity pool and resulted in losses of $100 million
Integration and interoperability risks
Cross-chain bridges face challenges when it comes to integrating with various blockchain networks and ensuring seamless interoperability. Different blockchains have unique technical specifications, consensus mechanisms, and security measures, which can create complications when attempting to establish a bridge between them.
Governance is another critical aspect of cross-chain bridges, as decisions regarding upgrades, security, and bridge parameters can have significant implications for the users of the bridge. Poorly designed governance models can lead to centralization of power, disputes, or even malicious actions by bad actors.
In 2020, the decentralized finance (DeFi) platform Yearn Finance faced a governance exploit, where attackers were able to mint 160,000 YFI tokens, worth around $2 million at the time. The exploit was due to a flaw in the governance contract, which allowed the attacker to mint new tokens without the required amount of YFI in their wallet. The attacker then used these tokens to vote on proposals and gain control of the protocol’s governance1. In 2021, Yearn Finance faced another exploit, where attackers made off with $11 million worth of stablecoins from the yDAI vault. The exploit was due to a vulnerability in the vault’s code, which allowed the attacker to drain the funds. The price of Yearn Finance’s governance token, YFI, dropped by 15% in less than two hours after the exploit. These attacks demonstrate the importance of implementing robust security measures to protect DeFi protocols against governance exploits and vulnerabilities in their code.
