Bridge Security

bridge_security_improvment(1)The Critical Importance of Security in DeFi Bridges and Interoperability: MetalSwap's Approach

As decentralized finance (DeFi) continues to thrive, and Web 3.0 technologies gain traction, interoperability between various blockchains becomes increasingly vital. DeFi bridges have emerged as essential tools, enabling the smooth transfer of tokens and assets across different blockchains.
However, ensuring the security of these bridges is of paramount importance, given the potential risks involved. In this blog post, we'll explore the significance of DeFi bridges, their security aspects, and some of the most well-known bridges in the market. We'll also discuss MetalSwap's approach to bridging its XMT token to different chains and the development's ongoing efforts to ensure the best security for the users, just like we did in the past.

DeFi Bridges: A Brief Overview

DeFi bridges, or cross-chain bridges, are decentralized applications (dApps) or protocols that enable the secure transfer of assets, such as tokens or cryptocurrencies, from one blockchain to another.
They facilitate the exchange of information, cryptocurrency, fungible or non-fungible tokens (NFTs) across blockchains, breaking down the silos that often limit the flow of data and tokens. These bridges play a crucial role in promoting interoperability between various blockchain networks like Ethereum, Avalanche, Polygon, Solana, and Arbitrum, among others.

MetalSwap's XMT Token and Interoperability

MetalSwap, the platform that enables Hedging Swaps with digital Assets, has its native token, XMT, initially built on the Ethereum network, where the highest level of security resides. Recognizing the need for interoperability, MetalSwap has expanded its reach by bridging the XMT token to two additional chains – BNB Chain and Polygon Network. To plan future strategies for XMT and its organization, MetalSwap's DAO is diligently profiling all bridge solutions and is already in touch with some of the teams mentioned in this article.

The Importance of Security in DeFi Bridges

The security aspect of DeFi bridges is crucial for several reasons:

  • Trust: Users must trust that the bridge will securely and accurately transfer their assets between blockchains without risking the loss of their funds. If security is compromised, users may lose trust in the bridge, potentially leading to a decline in adoption and usage.

  • Value protection: A secure DeFi bridge ensures that the value of the assets being transferred is preserved. A security breach could result in the loss or theft of assets, affecting individual users and the entire ecosystem.

  • Ecosystem integrity: A compromised bridge can undermine the integrity of the entire DeFi ecosystem, as it may deter new users from entering the space and cause existing users to question the reliability of other DeFi applications and platforms.

Notable DeFi Bridges and Their Differences

Several DeFi bridges have emerged in the market, each with its unique approach and features. Some of the most popular ones include:

Celer cBridge: This decentralized and non-custodial asset bridge supports over 150 tokens across 40+ blockchains and layer-2 rollups. Built on the Celer Inter-chain Message Framework, it uses the Celer State Guardian Network to enable liquidity across different blockchains.

Cross-Chain Bridge: Developed by the Tixl organization (now Autobahn Network), this platform supports the bridging of both tokens and NFTs across multiple networks, including Avalanche, BNB Chain, Polygon, Ethereum, and Fantom.

Multichain: Formerly known as Fantom Anyswap, Multichain is a cross-chain router protocol that supports the largest number of token types among all bridge services. It enables the flow of data and assets across various blockchain networks.
This is the one and only bridge used for XMT cross-chain operations until now.

Portal Token Bridge (formerly Wormhole): Powered by the Wormhole protocol, this bridge enables transfers of both tokens and NFTs across different chains, supporting networks like Acala, Algorand, Arbitrum, Avalanche, Ethereum, and more.

Synapse Bridge: The Synapse protocol provides secure cross-chain communication through its universal interoperability model, supporting a wide range of blockchain networks such as Ethereum, Arbitrum, Avalanche, BNB Chain, Optimism, Polygon, and others.

Umbria Narni Bridge: This bridge employs liquidity pools to facilitate blockchain asset transfers, holding assets across multiple chains. It currently supports networks like Polygon Mainnet, Ethereum Mainnet, BNB Chain, and Avalanche, with plans to expand to more networks in the future.

The Security Imperative in DeFi Bridges

Considering the high stakes involved in asset management, ensuring the security of DeFi bridges is critical for the evolution of the entire ecosystem. Some key aspects to consider for enhancing bridge security include:

  • Rigorous audits: Regular security audits by reputable firms can help identify vulnerabilities and potential exploits, allowing bridge developers to address them before they're exploited by malicious actors.

  • Transparency: Open-source code and transparent development processes can encourage community scrutiny, making it more challenging for security flaws to go unnoticed.

  • Multi-signature and time-lock mechanisms: Implementing multi-signature requirements and time-lock mechanisms can help minimize the risk of unauthorized transactions and increase the overall security of a bridge.

  • Layered security: Employing multiple layers of security, such as hardware security modules (HSMs) and secure enclaves, can further strengthen the protection of sensitive bridge operations


DeFi bridges play a crucial role in promoting interoperability within the blockchain ecosystem. They facilitate seamless asset transfers between different networks, which is essential for the growth and development of the DeFi, involving coins, tokens, NFTs, and whole DAO structures. MetalSwap's team knows this and wants to be up-to-date with all of those important and powerful tools.

One way to differentiate risk could be to use more than one bridge technology together and implement technologies that until recently did not even exist!
