The third partner that we will talk about is Axelar. Axelar delivers secure cross-chain communication for Web3. Secure means Axelar is built on proof-of-stake, the battle-tested approach used by Avalanche, Cosmos, Eth2, etc. Cross-chain communication means you can build a complete experience for your users that lets them interact with any asset, any application, on any chain with one click.

Axelar Network is created to bridge the blockchain ecosystems and enable applications to communicate frictionlessly across them. Validators collectively run a byzantine consensus protocol and run the protocols facilitating cross-chain requests. Anyone can join the network, participate, and use it. The underlying network is optimized for high safety and liveness requirements unique for cross-chain requests.

Axelar network also includes a protocol suite and APIs.

The core protocols are:

• Cross-Chain Gateway Protocol (CGP).

This protocol is analogous to Border Gateway Protocol on the Internet. This protocol is used to connect multiple autonomous blockchain ecosystems and is responsible for routing across them. Blockchains do not need to “speak any custom language”, their platform developers do not need to make any custom changes on their chains, and their chains can be plugged into the global network easily.

• Cross-Chain Transfer Protocol (CTP).

This protocol is analogous to application-level protocols File Transfer, Hypertext Transfer Protocols on the Internet. It is an application-level protocol stack that sits on top of routing protocols (such as CGP and other routing technologies). Application developers can connect their dapps on any chain to perform cross-chain requests. Users can use the CTP protocol to interact with applications on any chain using simple API calls analogous to HTTP GET/POST requests. Developers can lock, unlock, and transfer assets between any two addresses across any blockchain platforms, execute cross-chain application triggers (e.g., an dapps on chain A, can update 1 its state if some other application on chain B satisfies some search criteria (interest rate > X)), and perform general cross-chain requests between apps across chains (a smart contract on chain A can call to update a state of a smart contract on chain B). This protocol enables the composability of programs across blockchain ecosystems.

Axelar network offers the following advantages:

• For blockchain platform builders:

Ability to easily plug-in their blockchains to all other blockchain ecosystems. Only a threshold account needs to be set up on the chain to plug into the network.

• For dapps builders:

Application builders can host their dapps anywhere, lock, unlock, transfer assets, and communicate with applications on any other chain via CTP API.

• For users:

Users can interact with all applications across the ecosystem directly from their wallets. A Platform for Builders. Finally, Axelar network is a platform for developers and a global community. Its governance model is open to anyone. Developers can propose new integration points, routing, and application-level protocols, and the users can decide whether to adopt them by voting on the proposals and, if approved, validators will adopt the changes.

There are several strongs backers on board, such as Polychain Capital, Dragonfly Capital, Galaxy, Coinbase Ventures, Binance etc.

And — strong partners as well: Avalanche, Cosmos, Ethereum, Osmosis, Polkadot, Moonbeam, etc.

Now, dApps can communicate across chains using Turing-complete calls and messages on a permissionless Proof-of-Stake transport layer. Axelar goes far beyond sending wrapped assets with General Message Passing, which carries any payload securely cross-chain. Applications can call any function on any connected chain, and deliver a one-click experience for users on any other connected chain. This is a new kind of dApp development that puts users first and lets developers build on the platform best suited to their use case. Cross-chain communication is easy. Secure cross-chain communication is hard. Most solutions today are permissioned multisigs, based on proof-of-authority, which has lost hundreds of millions in security exploits. Axelar network security is based on delegated proof-of-stake: a permissionless, dynamic validator set applies a consensus approach that is similar to the networks Axelar connects.

Atop of the Axelar stack sits an application-development layer, used to compose across any number of chains. Developers go cross-chain without new programming languages or added complexity. They focus on building the functionality that differentiates their dApp.
