ChainX Technical Committee: How is LayerZero changing the crypto world?

1.Unify the liquidity of all bridges

To illustrate this more vividly, let’s take as an example: has established large-scale warehouses in major cities in China. When a user buys a certain product, does not need to ship to the user from another city far away from the user, but directly distributes the product stored locally to the user. Obviously, this reduces all kinds of problems in the logistics process.

2. Interoperability (Universal Messaging/Contract Calling)

Here is an example of cross-chain lending:
Assuming you own ETH on Ethereum and want to participate in mining on Avalanche, here are the steps currently required:
1. Lending ETH on Ethereum
2. Borrow assets using collateralized ETH
3. Bridge to Avalanche (toll)
4. Exchange to AVAX (fee, you need to already have AVAX)
5. Enter mining
6. From mining coins to native assets (fees)
7. Bridge back to Ethereum (fees)
8. Repay the loan on Ethereum
9. Recover Collateral

Now compare with LayerZero:
1. Lending ETH on Ethereum
2. Borrow AVAX directly on Avalanche
3. Enter mining
4. Pay off your loan on Avalanche
5. Release collateral on Ethereum

This involves calling at least 3 existing Dapps, in short, LayerZero provides a simpler and cheaper user experience.

Another example is that existing Dapps that enable one-click exchange of users’ native assets on two different chains can only swap the tokens on the original chain before using the bridge to cross-chain. Instead, it cannot cross-chain to the target chain first and then swap between tokens. Bungee ( is one such example.

However, cross-chain bridges using the LayerZero protocol (such as Stargate and, in the future, SoSwap) allow user assets to be cross-chained from the original chain to the destination chain before swap. this is due to the ability of the LayerZero protocol to have programmable contract calls. Specifically, LayerZero bridges are cross-chain combinable, which allows cross-chain transfers to be combined with the destination chain’s smart contracts, a feature not available in other bridges. Current bridges only provide traditional composability, supporting combinations with smart contracts on the source chain, but not with the destination chain. Cross-chain asset transfers via the LayerZero bridge, however, can be combined with contracts on both the source and destination chains, maximizing their flexibility. For example, an asset can be swapped at the source chain, bridged to the destination chain with LayerZero, and completed on the destination chain, all in the same cross-chain transaction. Cross-chain composability provides convenience beyond all existing solutions and opens up many new opportunities for cross-chain applications.

3. Imagine: Building a new Ethereum Layer 2 network with LayerZero protocol



ChainX is the largest Layer-2 network of Bitcoin, based on Substrate, and will evolve into the Polkadot Secondary Relay Chain.
