MetaMask vs Rabby, what is the difference?

MetaMask vs Rabby is a comparison of two self-custody wallets used mostly for Ethereum and DeFi apps. MetaMask is the older and more widely known option. Rabby was launched in July 2021 by DeBank, a DeFi portfolio tracker, and is built around showing what a transaction will do before you sign it. Neither company holds your keys. This page compares features and does not say which is better.

Rabby wallet vs MetaMask, how do they work with apps?

Both wallets inject the same kind of connection into your browser, so most Ethereum apps work with either. Rabby's GitHub page even asks app developers to show separate MetaMask and Rabby buttons, since both use the same browser object.

One difference is network switching. When you open an app, Rabby picks the network that app needs, a feature DeBank highlighted at launch. In MetaMask you choose networks from a menu. The background on each wallet is in what is Rabby wallet and what is MetaMask.

Which networks do MetaMask and Rabby support?

Rabby covers Ethereum and EVM chains such as BNB Smart Chain, Arbitrum, Base, Optimism, Polygon and Avalanche, and lets you add custom EVM networks with fewer features. According to CryptoSlate, it does not support native Bitcoin, Solana or Tron accounts.

MetaMask's multichain accounts give each account one EVM address, one Solana address and one Bitcoin address. MetaMask notes that hardware wallet accounts stay EVM-only for now. Rabby supports a wide range of hardware wallets, including Ledger, Trezor and BitBox02.

How does the Rabby security check compare with MetaMask alerts?

Rabby simulates each transaction and shows the expected balance changes before you sign. It also flags suspicious approval requests, risky contracts and high price impact. CryptoSlate notes that these are warnings, and a user can still choose to sign. Rabby also has tools to review and revoke past token approvals, which matters because disconnecting from an app does not cancel its spending permission. The guide to revoking token approvals explains why.

MetaMask has security alerts that are on by default. They check transactions and signature requests for signs of fund loss, using MetaMask's own analysis and partners including Blockaid. MetaMask labels results as Warning or Malicious, and says alerts do not catch every threat and do not block you from confirming.

Neither tool can protect a leaked recovery phrase. Common attacks are covered in crypto phishing and wallet drainers.

What are the fees for Rabby vs MetaMask?

Both wallets are free to install, and network fees apply to every transaction. For built-in swaps, CryptoSlate's October 2026 review lists a 0.25% Rabby fee, with some same-chain swaps between listed tokens exempt, and 0.25% on Rabby Bridge. MetaMask's support page lists a 0.875% fee on swaps. Fees can change, so the quote shown before confirming is the figure that applies.
