Bridging assets between blockchains has traditionally been centralized and poses a huge risk. At Mettalex, we have taken a different approach by leveraging Fetch.ai Agents' tech infrastructure to autonomously and securely facilitate the migration of anyMTLX (BNB Smart Chain) to MTLX (Ethereum).

This article breaks down how Mettalex Agents power this seamless cross-chain bridge, ensuring a trustless and efficient migration.

The Problem: Why a New Approach Was Needed

anyMTLX, the bridged version of MTLX on BNB Smart Chain, was introduced to improve accessibility. However, due to third-party issues, the bridge back to Ethereum became unavailable, trapping liquidity and causing uncertainty for holders.

Traditional bridging solutions rely on:

• Liquidity Pools: Prone to drain risks and impermanent loss.

• Centralized Validators: Single points of failure.

• Manual Claims: Tedious and inefficient for users.

Instead of these legacy solutions, Mettalex agents enable an autonomous, trustless, and secure migration.

How the Agent-Based anyMTLX to MTLX Bridge Works

The Mettalex bridge, powered by Fetch.ai’s autonomous agent technology, operates through Agents that monitor, verify, and execute cross-chain transactions seamlessly. These agents eliminate manual intervention,ensuring faster and more secure transactions.

Step-by-Step Flow of the Agent Powered Bridge

The following steps outline how the anyMTLX-to-MTLX bridge works, using agents for verification and execution.

1. User Locks anyMTLX on Binance Smart Chain

The process starts when the user initiates the bridge by locking their anyMTLX tokens into a Funds Lock contract (0x18e52361188DE55fa014BCb43c8e784aE2Df66C7) on the Binance Smart Chain (BSC).

2. BSC Agent listens for Transactions

An agent deployed on BSC continuously monitors transactions on the contract. When a new funds lock transaction occurs, it detects and records the event.

3. BSC Agent Communicates with the Ethereum Agent

Once the BSC agent detects a valid funds lock, it communicates with its counterpart agent deployed on Ethereum. It supplies:

• The Transaction Hash

• The User’s Wallet Address

• The Amount of anyMTLX Locked

4. Ethereum Agent Verifies the Transaction

The Ethereum agent now cross-verifies the transaction on the Binance Smart Chain.

• It fetches transaction details directly from the BSC network.

• It ensures the correct amount has been locked and the sender address matches.

Once verified, the Ethereum Agent initiates the next step.

5. Ethereum Agent triggers funds transfer

Upon successful verification, the Ethereum agent interacts with the Funds Transfer contract (0x180C59f93b3b59f9416255EE43135aa8Ed9c22e2) on Ethereum. It executes the transaction, transferring MTLX equivalent to the locked anyMTLX.

6. User Receives MTLX on Ethereum

The final step! The user receives their MTLX tokens in their Ethereum wallet, completing the bridge transaction without intermediaries or manual approval delays.

The anyMTLX to MTLX bridge marks a significant milestone for Mettalex in using agents for cross-chain trading and migration.

Bridge Stats:

Total bridged transactions: 125

Total amount bridged: 429,304.28

Unique users who locked anyMTLX: 103
