The Cross-Chain Trading Feature on the Mettalex Public Beta is now live! This user guide will walk you through the platform and help you explore the new Cross-Chain Trading Feature.

Important Note for Users of the Public Beta

Welcome to the Mettalex Public Beta! Please note that this version is still in development and runs on the Dorado Testnet on the Fetch Chain and the Amoy Testnet on the Polygon Chain. This is an unstable version, and it does not involve real money. We appreciate your participation in this testing phase and encourage you to report bugs or issues.

Before we dive into the Cross-Chain Trading Feature, if you are new to Mettalex and need assistance with ASI Wallet setup or single-chain trading, please refer to our Mettalex User Guide: Public Beta for a detailed walkthrough.

Now, let's get started with Cross-Chain Trading on Mettalex Public Beta!

Steps to Get Started:

1. Download MetaMask Wallet Extension for Polygon Amoy

You can skip this step if you already have the Polygon Amoy network on your MetaMask.

To start using Mettalex's Public Beta, you must install MetaMask and configure it to work with Polygon Amoy.

Follow these steps:

• Visit the MetaMask Extension page and click Add to Chrome.

• Once installed, pin the extension to your browser.

• Follow the on-screen instructions to set up your wallet successfully.

• Make sure you are connected to the Polygon Amoy network. If it's not automatically added while connecting the wallet to the Mettalex platform, you can manually add it by visiting Chainlist and adding the Polygon Amoy network by clicking "Add to Metamask."

Accessing Cross-Chain Trading Feature:

• Visit beta.mettalex.ai to access the Public Beta platform.

Step-by-Step Instructions for Cross-Chain Trading:

Placing a Trade from Dorado Testnet (Fetch) to Amoy Testnet (Polygon)

Connect Your ASI Wallet

• Click Connect Wallet on the top right of the platform.

  

• Select ASI Wallet and approve the connection.

  

  Get Testnet Tokens

• Click the Faucet button to receive testnet tokens.

  

• You will need TESTFET, FET, and USDT tokens to begin the trade. Select TESTFET First and get FET and USDT by approving the transaction.

Place the Trade

• Navigate to the Trade Section and select from token as FET (Dorado) to token as USDC (Polygon Amoy).

  

• Enter the amount of FET you want to trade for the USDC you wish to receive. The asset's price is automatically calculated (e.g., 1 FET —> 2 USDC, Price = 2)

  

• Enter the Polygon wallet address where you want to receive USDC on the Amoy network.

• Click Trade.

• Ensure you have enough gas fees on the network for the transaction and sufficient agent balance, or perform an Agent top-up. Refer to the important note below for more details about the Top-up process.

Create or Link an Agent

A popup will appear asking whether you want to Create a New Agent or Link an Existing Agent.

If this is your first time, select Create New Agent.

The system will automatically perform a series of transactions, which include:

• Creating your trading agent.

• Transferring 0.5 FET to the agent for transaction fees.

• Create an escrow contract and map it to your account.

Completing the Order

Once all the transactions are signed and completed and the order is placed, it will appear in the Open Orders Section. When a matching trade occurs, your agent will automatically interact with the other agent and complete the trade. The entire process is seamless and automated, ensuring your trade is executed successfully.

Important Note: Gas for Agent Transactions

Please note that all agent transactions utilize gas for execution. To ensure smooth operation, you should top up your agent directly from the Agent Top-up button at the top right of the platform. Your agent will be topped up with 0.5 FET on the Dorado or 0.5 POL on the Amoy chain.

All the details of your agent, including the agent's address and wallet address, are visible in the wallet-connected area at the top right of the platform.

Placing a Trade from Amoy Testnet(Polygon) to Dorado Testnet(Fetch)

Now that you have placed the first part of the Cross-Chain trade (FET to USDC) let's place an opposing trade: USDC (Polygon Amoy) to FET (Dorado). Now click Connect Wallet and select Metamask Wallet from the popup.

Get POL for Gas Fees

• Before you proceed, you will need POL for gas fees on the Polygon Amoy.

• Visit the Polygon Faucet or join their Polygon Discord server to request the faucet. You will receive 5 POL-on requests; check the attached screenshot below for reference.

  

• Once received, Request USDC and USDT from the Mettalex Faucet.

Place the Trade

• From the Trade section, select from the token as USDC (Polygon Amoy) and the token as FET (Dorado) for your trade.

  

• Click Trade, and a pop-up will ask you whether to Create a New Agent or Link an Existing Agent.

  

Linking or Creating an Agent

• If you have already created an agent on a different chain (e.g., FET), you can choose to Link an Existing Agent.

• Linking your agent ensures that your wallets are treated as a single user for cross-chain trades.

• If you decide to Link an Existing Agent, you will transfer 0.5 POL to top up your agent from Polygon Amoy.

For this guide, let's select Create New Agent to proceed with the trade.

Complete the Trade

• Once the agent is created, topped up, and mapped with the escrow contract, the trade will be executed when a matching order is found.

• If you encounter a "Transaction Declined" error while placing a trade, it may be due to the Polygon Amoy RPC. Try updating the RPC link for a smoother transaction flow. You can find the updated link on Chainlist.

• This completes the Cross-Chain Trading process from the Polygon Amoy to the Dorado.
