What are cross-chain swaps?

Cross-chain swaps are a type of cryptocurrency transaction that enables users to exchange assets between different blockchain networks. For example, swapping Bitcoin (BTC) on the Bitcoin network for Ethereum (ETH) on the Ethereum network.

How does MetaMask support cross-chain swaps?

MetaMask has integrated with various decentralized exchange (DEX) protocols that enable cross-chain swaps. These DEXs use bridges or sidechains to facilitate the transfer of assets between different blockchain networks. When you initiate a cross-chain swap through MetaMask, the wallet interacts with these DEXs to execute the swap.

• Security: MetaMask ensures that your assets remain secure throughout the swap process, as it’s a non-custodial wallet that never stores your private keys.
• Efficiency: Cross-chain swaps through MetaMask are often faster and more cost-effective than traditional exchange-based methods.

Which blockchain networks are supported for cross-chain swaps on MetaMask?

Currently, MetaMask supports cross-chain swaps between Ethereum (ETH), Binance Smart Chain (BSC), and Polygon (MATIC) networks. More networks will be added in the future.

How do I initiate a cross-chain swap on MetaMask?

1. Open MetaMask and ensure you have the required assets in your wallet.
2. Select the asset you want to swap and click on the “Swap” button.
