Cross chain bridges so vulnerable:

On the one hand, they are off-chain solutions. Build a token bridge that do not benefit from the inherent security and decentralization of the blockchain ledger. Bridges are solutions that connect different blockchain networks and perform complicated operations to facilitate cross-chain asset exchanges. When it comes to multi-chain bridging, the complexity of the infrastructure increases with each added blockchain network, increasing the chance of a code bug or smart contract vulnerability occurring.
Second, most chain-of-custody bridges are increasingly centralized and contain large amounts of crypto assets. The most popular centralized bridge, Wrapped Bitcoin , currently holds 267,198 BTC , worth over $5.4 billion at the time of writing. WBTC is even more vulnerable because all of these assets are held by a central custodian known as BitGo — making it a single point of failure and an attractive target for hackers looking to overcome the inherent security of blockchain networks.
Therefore, Bitcoin holders looking to interact with Ethereum-native DeFi applications must trust a central entity with control and ownership of their private keys, which defeats the spirit of decentralized finance beyond making their assets digital are more vulnerable. Users must also trust that the central custodians will keep their word and send them their wrapped assets once the original assets have been deposited.
Centralized bridges also rely on fewer validating nodes or often a single entity, making these protocols even more corruptible. This also makes custodial bridges vulnerable to social engineering schemes and human error, which is part of what led to Axie Infinity. Ronin Bridge being hacked for $600 million .
In conclusion, most of the existing cross-chain bridges are vulnerable because they handle complicated operations on several different blockchain networks without benefiting from the inherent security of the blockchain. Additionally, most custody bridges are overly centralized, holding large amounts of digital assets through a central party, creating a single point of failure.
Moving towards safer cross-chain bridges:
Closing the security loopholes of build a cross-chain bridges is essential to creating the interoperability and trust necessary for mass adoption of blockchain. For that to happen, developers need to rethink cross-chain bridging solutions, as the security of one bridge can compromise an entire blockchain network.
A more secure multi-chain future will require noncustodial blockchain bridges that are truly decentralized to eliminate the single point of failure associated with centralized bridges. Decentralized bridges that are based on multiple independent validation nodes also eliminate the risk of human error and social engineering schemes.
Future blockchain bridges will also eliminate central custodians, who jeopardize user funds by keeping them in a single off-chain storage solution, which is a prime target for hackers. Furthermore, the blockchain bridges of tomorrow will likely eliminate the complex locking and minting mechanism employed by most existing solutions.
For example, non-custodial bridge Urraca is solving these security concerns by facilitating cross-chain trades without pooling assets. Instead, Magpie uses the Wormhole Bridge as a messaging layer to communicate asset trades while performing asset trades from secure, chain-specific stablecoin pools. As a result, digital assets never have to traverse the dangerous waters between blockchain protocols, creating more security for users.
Noncustodial bridges that are operated by smart contracts will likely also undergo more extensive security audits or create bug bounty incentives to find potential vulnerabilities. This will be important for cross-chain security and building stronger smart contracts.
