For cross -chain, we have heard many names: cross -chain bridge, chain operating, full -chain, account abstraction, chain abstraction, intention trading, and so on.It sounds a headache.
One phenomenon that we can all observe is that there are more and more public chains.Previously, the goal of the new public chain was to increase TPS and reduce GAS fees, and adopted different technical directions, such as Solana, Aptos, Conflux, major layer2 and so on.Today, the purpose of the new public chain has changed, and more out of its own ecology, such as ecological Layer2, Aveo public chain, LOOT public chain, etc.出一条成功公链，比如base、blast等等
在这个牛市中，公链肯定越来越多。Therefore, the demand for cross -chain is also surging.In the face of these, there is no need to be afraid.It is developed step by step.
The cross -chain bridge was from the 21st year of Niushi ZTE, and the main function was the cross -chain of assets.After the DEFI explosion in ETH at the time, BSC, Avalanche, Fantom and other public chains appeared and broke out.Therefore, there is a demand for cross -chain demand for relatively large assets.The famous projects at the time were Multichain (formerly known as Anyswap) and Celer Bridge.
The public chain is like islands.With the increase of the public chain and the rise of the non -EVM system, the islands of the islands are formed and split.Therefore, it is just that the cross -chain of assets cannot meet the needs of the multi -chain era.
First of all, the problem of the wallet that we must solve is that the public chain and the wallet must be configured. Fortunately, the EVM is equipped with one hundred and eighty.There is no shortage of one, and the experience is more than bad.So, the abstract account appearedThe abstract account is a wallet to get all public chains, such as OK wallets with good reputation recently.In essence, an abstract account is a contract account. It can also use social accounts to find the lost account and uniform functions such as Gas token.
To solve the problem of wallets in each chain, it is also necessary to solve the problem of DAPP in each chain.Then, the demand for the most bottom warehouse is the transmission of information on cross -chain. We hope that in the A chain, we can read the status of the B chain, read the information of the chain in the B chain, or the status of the A chain and the B chain at the same time.This is the interoperability of the chain.When you can pass information across the chain, you can do a lot of things, such as full -chain borrowing, cross -chain voting control, and so on.For the DEX and DEFI protocols, the benefits are greater. The liquidity on different chains is not split. It can be used uniformly to achieve liquidity aggregation.
Imagine that after having assets cross -chain, cross -chain information transmission, and abstract wallets, when we operate on the chain, what chain is behind it does not need to be so clear.For example, we want to mortgage the USDT in the wallet to borrow to borrow ETH. We don’t need to care about whether the USDT is on the BNB chain or on the ARBTRUM chain. It can be used to mortgage to the lending agreement and pay the GAS uniformly.而贷出的ETH的背后也不需要管是来自哪条链上，Dapp会自己根据流动性来协议。这便是链抽象。
这个周期上线的跨链协议，基本都是链抽象协议。都拥有跨链信息传递、资产跨链等功能。Their difference is that the implementation method is different from the technology used.So let’s focus on different things below
On this track, the most head is Layerzero, Wormhole, Axlar
1.axlar
Axlar’s biggest advantage lies in full -chain deployment.Axlar proposed a concept of interchain. In this concept, all web3 applications will have a unified development environment. This development environment will accommodate different logic on multiple chains and support users from multiple chains.EssenceSimply put, the DAPP developed by Axlar can be deployed on it to support all public chains.The public chain supported by Axlar is also the three of the three.
2.layerzero
Layerzero should be a household name.It is characterized by lightweight cross -chain information transmission, so it chooses to use prophecy machines and relay networks to complete data transmission.Layerzero simplifies the process of cross -chain information interaction. It is not responsible for the verification of information, but to ensure security by cross -chain parties.So in terms of efficiency, Layerzero is higher.
3.Wormhole
Wormhole originated from the cross -chain bridge established by the two networks of Ethereum and Solana. It consists of upper components and under -chain components.The components on the chain mainly include the emitter, the corehole core contract, and the trading log.The modules under the chain are mainly composed of 19 guardians nodes and message transmission networks.Thanks to the strong ecology of Solana, Wormhole’s cross -chain amount is the highest.

In addition to the head, there are several very important members on this track, and there are hope to rise into a giant in the future.
4.zetachain
Although ZetAChain also provides cross -chain information, it is mainly focused on the full -chain smart contract. With ZetAchain, it creates a decentralized application that can cross multiple chains such as Ethereum and Bitcoin.This is very similar to Axlar, and also uses COSMOS SDK.And in full -chain deployment, ZetAChain is more advantageous than Axlar.However, due to resources and popularity, Zetachain’s ecology is slightly inferior to the three giants.
Axlar’s structure is more similar to Zeta, but it is also obviously different.The same as Zetachain is developed based on COSMOS SDK.The difference is that it does not directly host EVM, so it does not support the same full -chain smart contract as Zeta.Therefore, Axlar’s target market is cross -chain message passing, which is similar to Layerzero.
5. POLYHEDRA
The core highlight of PolyHedra is ZK zero knowledge proof, with the fastest zero knowledge certificate (ZK) algorithm.Its core product ZKBridge ensures strong security without increasing additional trust assumptions.Through concise proof, it not only guarantees correctness, but also significantly reduces the verification cost on the chain.Its workload speed is several levels faster than existing solutions.Layerzero now uses ZKBridge as the default decentralized verification network (DVN) of many paths.Poyhedra’s support public chain reached 25.
6.particle network
PARTICLE Network has positioned itself as Layer1 in the module that provides chain abstraction. Users can manage accounts and liquidity on different chains under a unified interface without downloading various wallets for complex cross -chain transactions.Particle Network was originally the mainstream provider of the wallet abstract service.PARTICLE has been upgraded to wallet abstraction, chain abstraction, liquidity abstraction, GAS abstraction and other functions.So in the chain abstract track, its strength is still abstract wallet.
Under the giant rule, Particle focuses on new directions, such as BTC Layer2, Gamefi’s abstract wallet, Socaifi smart wallet, and so on.Particle laid the foundation for the 4 billion TVL of the Bitcoin Layer2 network Merlin.
