What Rabby is in 2026
Rabby is built by DeBank — the team behind the most-used DeFi portfolio tracker. Launched in 2022, Rabby positions itself as the power-user alternative to MetaMask, with deeper transaction analysis, multi-chain UX optimised for serious users, and open-source code.
Transaction simulation as a feature
Rabby's standout feature is transaction simulation. Every transaction shows you exactly what tokens leave and enter your wallet before you sign — in plain English, not raw hex. The simulator integrates with Blockaid and DeBank's own risk scoring to flag scams. This has prevented thousands of users from approving wallet-drainer transactions that MetaMask's older preview model might have shown as innocuous.
Multi-chain native UX
Unlike MetaMask, where switching chains requires manual network selection and approval, Rabby auto-detects which chain a dApp wants and prompts for the right one. The UX feels designed for users who work across 5–10 chains regularly rather than treating each chain as a separate context.
Open-source as a feature
Rabby is fully open-source — both extension and mobile code. For users who prioritise transparency in their wallet stack, Rabby is one of the few open-source consumer wallets with serious feature parity to closed-source competitors.
Who Rabby fits
Ethereum and EVM power users. DeFi traders who interact with new protocols regularly. Anyone who has been burned by a drainer or wants to prevent future attacks. Less ideal for users who only use 1–2 dApps regularly (MetaMask is sufficient) or who need Solana support (use Phantom).
