Rabby is a self-custody wallet for Ethereum and EVM chains, available as a browser extension and mobile app. It is built by the team behind DeBank.

Rabby has a built-in "Rabby Perps" interface that routes perps trades to Hyperliquid. Rabby earns builder-code fees on those trades, and DefiLlama has tracked them since September 2025: about $2.5M in total and $0.4M in the last 30 days (Oct 2026). Rabby also works as a wallet for HyperEVM and the Hyperliquid web app. Hyperliquid lists Rabby under Mobile apps on its official apps page.
