MetaMask Review: Still the Default, But Is Default Still Safest?
We ran MetaMask's new multichain accounts across Ethereum, Solana and a test swap for three weeks to see whether the wallet everyone defaults to has kept its safety edge now that it reaches past Ethereum.
Our verdict
MetaMask earned its default status on Ethereum honestly, and multichain accounts extending one seed to Solana, with Bitcoin coming, keep it ahead of wallets that still lock you to a single chain. The 0.875% swap fee is unremarkable next to rivals, and the wallet itself has not been the point of failure in the phishing losses that keep hitting its users; approving a malicious signature has. Anyone new to self-custody should still pair it with a hardware wallet before moving serious balances, because MetaMask's own security page cannot stop you from signing something you should not.
Best for: Ethereum and Solana users who want one seed across chains and a hardware wallet for larger balances
We set up a fresh MetaMask install, generated a new seed, and watched it produce three addresses at once: one for Ethereum and its EVM cousins, one for Solana, and a note that Bitcoin support is coming. That single moment is the biggest change to MetaMask in years, and most of its users have not noticed yet.
One seed, more than one chain
MetaMask spent a decade as the wallet you installed for Ethereum and only Ethereum. Multichain accounts change that: a single seed phrase now derives a Solana address alongside the usual EVM one, rolled out automatically to Extension version 13.5 and Mobile version 7.57 with no action required from existing users. Support for Bitcoin, Tron and Monad has been announced but was not live during our testing window.
We moved a small Solana balance into the wallet and it behaved exactly like the Ethereum side: same interface, same approval flow, no separate app or extension needed. For anyone previously juggling MetaMask for EVM chains and Phantom for Solana, this removes a wallet from the rotation.
What a swap actually costs
MetaMask charges a 0.875% service fee on swaps, disclosed separately from network gas, pool liquidity charges and price impact. We ran a $500 ETH-to-USDC swap during testing and the fee line matched that rate exactly, with no surprise deduction hidden in the quoted price.
