Testnet Guide

Never interacted with a dApp on testnet before? Follow this easy 3-step guide.

This is the current testnet for the Chain-Agnostic Token standard V1, which is live on Wormhole and has been audited by Halborn. The Chain-Agnostic Token V2 standard will be available with Axelar, CCIP, LayerZero and Wormhole and is coming soon.

Step 1: Install wallet

Install Metamask Wallet.

(On mainnet, we'll have multiple wallet options, but for testnet we've kept it to one.)

Step 2: Add networks (blockchains) to your wallet

The easiest way to do this is using Chainlist.

You'll only need to add 1 chain to try out testnet. We'd recommend Polygon (Mumbai), Avalanche (Fuji) or BNB testnet as it's easiest to get testnet tokens for these networks.

Step 3: Get testnet tokens

Testnet tokens will be required for gas (transaction fees). You'll be able to get these for free from each network's faucet.
