Swing Integrates deBridge for Capital-Efficient and Seamless Cross-Chain Value Transfers in 1 tx
deBridge Delivers True Cross-Chain Interoperability and Capital Efficiency for Swing
Swing is excited to share that we have integrated deBridge and deSwap, a protocol built with the deBridge generic messaging infrastructure, to enable more capital-efficient and seamless cross-chain value transfers and swaps in one transaction.
There are many decentralized bridges that support transfers of assets and liquidity between crypto networks, but deBridge is different. In addition to supporting token transfers, the protocol allows anyone to move a whole lot more, right down to messages and smart contract logic itself. Then there’s the full suite of products that are built on top of deBridge, further extending its capabilities and making it easier and more seamless for any project to go cross-chain.
In this article, we’ll run through how deBridge works, what makes it secure, and why it was a natural choice for Swing to integrate with deBridge toward our goal of full blockchain interoperability.
deBridge is a secure cross-chain infrastructure enabling seamless interoperability between blockchains while powering transfers of any messages and liquidity The protocol enables projects to connect smart contracts that exist on different chains, bundling them with value transfer into a single transaction (tx). This opens the door to a range of powerful possibilities, from cross-chain value transfer + any arbitrary action, cross-chain arbitrage, and NFT transfers.
While deBridge is an infrastructure layer between blockchains, there are also several complementary dApps (called deApps) built on top of it. These are for instance deSwap (cross-chain AMM), dePort (creation of cross-chain synths), and deNFT (Coming soon) which will enable cross-chain interoperability for NFTs upon launch.
How It Works
deBridge is a messaging infrastructure that powers generic cross-chain message transfers. What this means is that developers can write contracts that are executed across multiple blockchains with deBridge relaying the instructions using the CALLDATA command. This, and the implementation with off-chain validation, paves the way for a virtually unlimited number of dApps that can capitalize on the advantages of transferring value and messages in one transaction simultaneously.
With deBridge, there are essentially three types of data that can be transferred to the destination chain:
Value (i.e. tokens and liquidity)
Value + Messages
The most obvious use case for this technology is cross-chain swaps and value transfers, enabling orders to be filled across multiple chains to obtain the best possible pricing. This is how Swing currently utilizes deBridge, though the infrastructure also supports builders to develop cross-chain yield farming, arbitrage, governance, lending, and all types of protocols and applications that are looking to utilize cross-chain messaging.
Whenever a cross-chain tx is initiated via the deBridge smart contract, it is assigned a unique hash. This hash is an identifier of each transaction and makes sure that it’s a unique message with the deBridge protocol. deBridge validators track emitted events to deBridge on all supported chains and wait for finality to be achieved on the source chain until the specific transaction achieves finality before validation occurs.
If everything is correct, it is signed by the validator set using their corresponding private keys and pushed to the deBridge API. These validator signatures are stored on IPFS as proof and can be retrieved by anyone (user/keeper) to be passed through deBridge smart contract on the destination chain. Provided the minimum signature threshold has been met (8/12) by the deBridge validators, the deBridge smart contract will then execute the transaction and the call data will be transferred to the destination chain.
This setup provides both transparency and security, giving all participants a clear overview of tx progress and finality. It’s also important to note that deBridge has over 17+ audits, an ongoing bug bounty program, and a vast range of different security implementations and measures in place. More on that in this article.
deSwap is the first cross-chain AMM created by the deBridge team to take advantage of the protocol’s ability to execute multichain swaps. It can be integrated via their deSwap API or as a deSwap widget into third-party sites and applications, enabling blockchain projects to utilize deBridge’s cross-chain capabilities with no coding required.
The following features make deSwap one of the best AMMs of its kind:
Speed: trades are finalized in less than 2 minutes for most blockchains.
Simplicity: unlike some cross-chain platforms, deSwap doesn’t require users to have the gas token or the tokens to be claimed on the destination chain.
Efficiency: Optimal routing minimizes slippage and provides greater capital efficiency. All of these features will be improved with the launch of DLN.
deSwap Liquidity Network (DLN)
deSwap Liquidity Network (DLN) is a new cross-chain value transfer architecture and design for channeling liquidity cross-chain to where it’s needed, when it’s needed. With DLN, there’s no need for locked liquidity or wrapped assets. Instead, liquidity is supplied on demand in the most capital efficient way possible, all with low fees and no slippage
The design of DLN overcomes many of the downsides to operating in multiple blockchain ecosystems, such as the need to launch dedicated liquidity mining campaigns which has been the case to date. Normally, liquidity is stranded on one particular network and cannot be easily moved to where it’s needed in a timely fashion. With DLN, liquidity is transferred quickly with no extensive risks of locked liquidity.
The other advantage to DLN versus incumbent solutions is that DLN supports zero-slippage transfers. This ensures that users and projects don’t see profits eroded through excessive bridging fees.
Overall Features that define DLN include:
Zero slippage on any order side
Unlimited market depth
Guaranteed rates and lowest fees
Fastest settlement for cross-chain transfers
Native token bridging (no wrapped assets)
Limit orders for cross-chain swaps
Zero locked liquidity (0 TVL) at risk
Given the enormous power of deBridge and its flexible and innovative DLN, they were an obvious choice for Swing. Utilizing deBridge’s technology brings us and our users closer to enjoying all of the upsides of blockchain interoperability with none of the downsides.
Now assets, value, and data can move effortlessly between networks, capturing the full value of Web3. We’re very excited to work with deBridge on driving more seamless infrastructure and the cross-chain interoperability space forward.
Swing is a unified cross-chain solution for crypto liquidity and bridge aggregation on major EVM & Non-EVM networks such as Polygon, BSC, Avalanche, Moonriver, Harmony, xDai, Arbitrum, Fantom, and more. Swing's widget comes with custom configurations for 30+ cross-chain bridges and liquidity sources along with thousands of supported tokens.
