swaps got better

MetaMask Swaps just got better by enabling swaps on Layer 2 (L2) networks, Arbitrum and Optimism. In addition to being able to swap directly in your wallet, Swaps is also available in MetaMask Portfolio, your one-stop shop for aggregating assets across accounts, viewing multi-chain token balances and NFTs, and bridging to different networks.

As a refresher, MetaMask Swaps allows you to swap tokens directly from your desktop or mobile wallet, aggregating data from various decentralized exchanges (DEX) and market makers to ensure you get the best price at the lowest network fees. Previously available on Ethereum Mainnet, Binance Smart Chain (BSC), Polygon, and Avalanche, Swaps now expands its offering to the Layer 2 space with Arbitrum and Optimism.

Following last month’s bridging aggregator release, Swaps finds a second home in the dapp for a simple and convenient experience. Simply toggle over to the “Swaps” tab in the navigation bar to get started.

There are many benefits to using MetaMask Swaps’ intuitive interface:

  • Time and cost-efficiency: You can easily swap tokens with fewer approvals, slippage protection (wild price swings), and the most gas-efficient route for each trade.
  • Convenience: Swapping directly within MetaMask means you never have to leave the desktop/mobile wallet, or dapp. Everything is conducted in one place, allowing you to manage your assets easily.
  • Retaining control: Since Swaps gathers data from decentralized exchange aggregators, market makers, and DEXs, it allows you to swap one cryptocurrency token for another without having to sign up for a centralized exchange. MetaMask is a self-custodial wallet that grants you full ownership over your private key and ultimately, control over your assets.
  • Large token selection: Because it gathers data from a DEX, MetaMask Swaps allows you to access a large number of cryptocurrencies that may not be available on a centralized exchange, giving you more flexibility and choice when it comes to your investments.

Swap in one place


Whether you choose to use Swaps in the desktop/mobile wallet, or dapp, it's super convenient and straightforward, drastically reduces the number of steps needed, and the amount of exposure to third-party smart contracts.

Remember, MetaMask is only an aggregator of data that enables token swapping. That means we gather quotes, filter them, and you decide if you want to proceed with the transaction. We don't provide the liquidity, execute the trade, or sell you tokens.

Happy swapping! 💸
