Risk Warning for Cross-Chain Transactions: Security Risks That Cannot Be Ignored

June 07, 2025

In recent years, the rapid development of blockchain technology has driven the diversification of digital assets. As a means of breaking down barriers between different blockchains, cross-chain transactions have gradually attracted increasing attention from users. Cross-chain transactions can not only improve the efficiency of asset circulation but also provide users with a wider range of trading options. However, while enjoying the convenience of cross-chain transactions, many potential risks also arise. This article will delve into risk warnings associated with cross-chain transactions to help users remain vigilant when participating.

I. Basic Concepts of Cross-Chain Transactions

Cross-chain transaction

Cross-chain transactions refer to the process of transferring and trading assets between different blockchains. This process typically involves technologies such as smart contracts and cross-chain bridges, enabling different blockchains to communicate and trade with each other. The significance of cross-chain transactions lies in breaking the limitations of a single blockchain, providing users with a more flexible way to manage their assets.

Types of Cross-Chain Technology

Cross-chain transaction technologies can mainly be divided into the following categories:

Risk Warning for Cross-Chain Transactions: Security Risks That Cannot Be Ignored

  • Centralized cross-chain protocolThese types of protocols are usually maintained by centralized institutions, such as certain exchanges. When users trade on these platforms, they are essentially transferring assets from one chain to another, and the platform is responsible for executing this process.
  • Centralized cross-chain protocolDecentralized cross-chain protocols leverage the features of smart contracts and distributed networks, allowing users to trade directly between different blockchains without relying on centralized entities.
  • Relay chain technologyThrough relay chain technology, different blockchains are allowed to "perceive" each other's states, thereby enabling more efficient cross-chain transactions.
  • 2. Potential Risks of Cross-Chain Transactions

  • Smart contract security risks
  • Smart contracts are at the core of cross-chain transactions, but their security is often overlooked. Since smart contracts cannot be altered once deployed, any security vulnerabilities may result in asset losses. Therefore, when conducting cross-chain transactions, users must carefully verify whether the smart contracts they use have undergone professional audits.

  • Transaction delays and uncertainty
  • Cross-chain transactions involve multiple blockchains, and the confirmation time of transactions may be affected by factors such as the network status and block generation speed of each chain, which can lead to transaction delays. In addition, the differing transaction rules and state verification mechanisms of various blockchains may result in inconsistent transaction success rates, creating uncertainty for users.

  • Centralization risk
  • Centralized cross-chain trading services rely on third-party platforms, meaning that the security of users' assets is entirely dependent on the operational capabilities of these platforms. If a centralized service encounters problems, such as hacking attacks or poor management, users' assets will face significant risks.

  • Exchange rate fluctuation risk
  • In cross-chain transactions, due to the involvement of different digital assets, market price fluctuations may lead to a loss of asset value during the transfer process. Especially when converting to stablecoins or other types of assets, users need to pay attention to exchange rate characteristics to avoid transaction results being affected by market volatility.

  • Regulatory and Compliance Risks
  • Different countries and regions have varying regulatory policies regarding digital assets. When conducting cross-chain transactions, users need to understand the relevant laws and regulations and comply with compliance requirements. Failure to do so may result in legal liability or asset freezing.

    How to prevent the risks of cross-chain transactions

    Choose a secure platform

    When choosing a platform for cross-chain transactions, users should prioritize service providers with a good reputation and a record of security audits. Reviewing the platform's user feedback, historical transaction records, and security measures are essential steps.

    Use audited smart contracts

    When conducting cross-chain transactions, users must use smart contracts that have been audited by professional institutions to ensure that the contract code has no security vulnerabilities and to reduce the risk of asset loss.

    Pay attention to market trends

    Before conducting cross-chain transactions, users should understand the current market dynamics, especially the fluctuations in asset prices. By making reasonable risk assessments and employing effective fund management strategies, losses caused by market volatility can be reduced.

    Maintain good asset awareness

    Always pay close attention to the location and usage of your assets to prevent losses caused by improper operations or information asymmetry. At the same time, regularly update your personal security management knowledge to maintain good security awareness in your daily transactions.

    Handle compliance issues with caution.

    Cross-chain transactions involve complex laws and regulations, so users should regularly stay informed about policy changes in relevant regions. If necessary, professional legal advisors can be consulted to ensure the compliance and legality of transactions.

    Frequently Asked Questions

  • What is the difference between cross-chain transactions and regular transactions?
  • Cross-chain transactions refer to the exchange of assets between different blockchains, while regular transactions are usually completed on the same blockchain. Cross-chain transactions involve more technical and security considerations and are generally riskier.

  • How to choose a cross-chain trading platform?
  • When choosing a cross-chain trading platform, users should pay attention to multiple factors such as the platform's security, historical trading volume, user feedback, and technical support to ensure the safety of their funds.

  • What is the transaction fee for cross-chain transactions?
  • The transaction fees for cross-chain transactions are usually higher than those for single-chain transactions, as they involve interactions between multiple blockchains and have a more complex fee structure. Users should carefully review the relevant fee policies before making a transaction.

  • Are cross-chain transactions safe?
  • The security of cross-chain transactions depends on the platforms and technologies used. Utilizing audited smart contracts and trusted platforms can enhance security, but there are still certain risks involved.

  • What knowledge is required to participate in cross-chain transactions?
  • Users participating in cross-chain transactions need to understand basic blockchain and digital asset knowledge, including how to use wallets, the basic principles of smart contracts, and methods for analyzing market trends.

  • What is the outlook for cross-chain transactions?
  • With the emergence of more blockchain technologies and solutions, the prospects for cross-chain transactions are widely regarded as promising. They can enhance asset liquidity and provide users with more investment and trading opportunities, but at the same time, users need to strengthen their risk awareness to cope with potential challenges.

    As cross-chain transactions continue to evolve, staying vigilant and enhancing security awareness are indispensable responsibilities for every participant. By mastering the necessary information and preventive measures, one can more confidently enjoy the convenience and possibilities brought by this emerging mode of trading. When entering this field full of opportunities and challenges, be sure to make thorough preparations to reduce various risks and achieve secure investments.
