Plain English
Rabby is a self-custody EVM wallet made by DeBank, designed for active DeFi users. The killer feature: pre-transaction simulation that shows exactly what will happen (which tokens move, which contracts are involved, slippage estimates) before you sign.
How it actually works
Open-source. Auto-detects the right chain for each dApp interaction — no manual network switching. Shows USD value of every transaction. Built-in token approval manager and security warnings for suspicious contracts. No native swap fees (uses external aggregators).
What it means for you
Rabby is the DeFi power-user upgrade from MetaMask. The transaction simulation alone prevents most signing mistakes that cost users their wallets. For HNW DeFi activity at any scale, the additional security visibility is meaningful. Many advanced users run MetaMask for compatibility + Rabby for sensitive signing.
