Cross-chain swaps enable users worldwide to trade tokens from different blockchains seamlessly. By using smart contracts and cryptographic methods, these swaps allow for easy token exchanges without relying on centralized intermediaries. One popular approach is atomic swaps, which use hash time-locked contracts (HTLCs) to ensure the transaction is completed securely and irrevocably.

Interoperability protocols like the Interledger Protocol (ILP) and blockchain bridges facilitate the communication needed for cross-chain swaps. This enhances liquidity, encourages DeFi innovation, and promotes greater integration within the blockchain ecosystem.

How To Do Cross Chain Swap Work?

Cross-chain swaps, also known as atomic swaps, facilitate the exchange of assets between two different blockchains without the need for a centralized third party.

Initiation

When two parties wish to conduct a cross-chain swap across different blockchains, they establish the conditions and define the assets to be traded.

Hash Time-Locked Contracts (HTLCs)

To ensure enhanced security and trustlessness, smart contracts are utilized, specifically Hash Time-Locked Contracts (HTLCs). Cryptographic hash functions and time locks are employed to guarantee that the conditions of the swap are met.

Commitment

Both parties commit their assets into HTLCs on each blockchain. Assets are locked within the smart contract, deriving a digital key (the swap conditions) from it.

Verification

Before proceeding with the swap, both parties verify critical details, confirming the smart contract requirements to prevent fraud or malicious intent.

Simultaneous Execution

Once mutual agreement and conditions are met, the swap is executed. Assets locked on each blockchain are released and transferred to the respective parties.

Refund in Case of Failure

Should the conditions not be met within a specific timeframe before initiation, the smart contract allows for the return of locked assets to their original owners.

Cross Chain Swap Vs Bridges?

Cross-chain swaps and crypto bridges both facilitate the exchange of assets between different blockchain networks, but they operate in distinct ways. Cross-chain swaps, often referred to as atomic swaps, allow users to trade or transfer assets seamlessly without the need for a centralized exchange. These swaps are typically more decentralized, leveraging smart contracts—specifically Hash Time-Locked Contracts (HTLCs)—to ensure trustless transactions where users do not need to trust a third party. Examples include platforms like ThorSwap. 

On the other hand, crypto bridges act as intermediaries that enable the transfer of assets from one blockchain to another. While they can also use smart contracts, their degree of decentralization can vary, with some bridges being more centralized. Bridges like Wanchain create a connection between disparate blockchains, facilitating interoperability and enabling asset movement. They tend to be more user-friendly, handling the asset transfer process once users deposit their assets into the bridge. 

Both methods promote interoperability and access to a broader range of assets, but cross-chain swaps may require users to have a deeper understanding of blockchain mechanisms and smart contract interactions, while crypto bridges generally offer a simpler user experience. Transaction speeds for both can vary depending on the consensus mechanisms of the involved blockchains.

What Are The Risks Of Using Cross Chain Swap?

Cross-chain bridge vulnerabilities pose a significant hurdle in the realm of cross-chain swaps, often culminating in substantial security breaches. In 2022 alone, these breaches led to nearly a billion dollars in losses, constituting 69% of the total crypto sector theft that year. The intricate nature of bridge technology and dependence on external intermediaries amplify the likelihood of such incidents. Moreover, the complexity involved in executing cross-chain swaps diminishes user accessibility, hindering widespread adoption. Coupled with market volatility, which introduces financial uncertainties during swaps, tackling these challenges becomes imperative for ensuring the secure and seamless functioning of cross-chain swaps.
