We're excited to share that the Interchain Amplifier is going live on Testnet today and will begin a test phase!

This marks a significant milestone in enhancing blockchain interoperability. Axelar’s Amplifier capabilities seamlessly connect a broad range of blockchain consensus engines and traditional off-chain systems with minimal developer overhead.

The core components of the [Interchain Amplifier](https://docs.axelar.dev/dev/amplifier/introduction) on the Axelar network include:

* An on-chain message router
    
* Gateways
    
* CosmWasm methods for both receiving and sending messages
    

Please note that the testnet is in the testing phase, and we will be onboarding new chains there in the coming weeks, so stay tuned.

We've just published several relevant technical articles and documentation updates.

### **ITS**

* [Building Multichain Stablecoins Part One:](https://blog.axelar.dev/building-multichain-stablecoins-part-one) Deploy multichain stablecoins with Axelar's Interchain Token Service: custom ERC20 integrations, cross-chain transactions, and upgradable contracts.
    
* [Building Multichain Stablecoins Part Two](https://blog.axelar.dev/building-multichain-stablecoins-part-two): Deploy your stablecoin on a second chain, send a transaction between two chains with your token, and upgrade your token.
    
* [How to Mint an ERC-20 Token on Base with the Interchain Token Service in 5 Steps:](https://moralis.io/how-to-mint-an-erc-20-token-on-base-with-the-interchain-token-service-in-5-steps/) This step-by-step guide will teach you how to mint a multichain ERC-20 token on the Base network using Axelar’s Interchain Token Service (ITS) and use the Moralis Token API to retrieve token balances easily.
    

### **Amplifier**

* [Governance Proposals for Integrating New EVM-based Chains](https://docs.axelar.dev/dev/amplifier/chain-integration/governance-proposals): Learn how to onboard a new chain with the Axelar Amplifier through governance proposals.
    
* [Add rewards for Amplifier chain integrators](https://docs.axelar.dev/dev/amplifier/add-rewards): Learn how to add funds to the rewards pool of an Amplifier-integrated chain.
    

### **Everything Else**

* [How to fix `command not found: axelard` / `tofnd`](https://blog.axelar.dev/how-to-fix-command-not-found-axelard-tofnd): If you have followed the Axelar setup instructions for [becoming a verifier](https://docs.axelar.dev/validator/amplifier/verifier-onboarding) but keep running into a command not found error when trying to run axelard or tofnd, try navigating to the folder your binary is in and referring directly to that binary instead of setting up an alias.

### Building a Multichain Tax Contract with ITS

Join us for a live workshop where we'll build a Multichain Tax Contract using the Interchain Token Service (ITS). Using the powerful Interchain Token Service (ITS), you'll learn how to create, deploy, and manage a custom token that operates across multiple networks. Watch as we implement smart contract logic that mints, burns, and applies fees to tokens as they travel between chains.
