Scores
Each criterion carries equal weight. The overall score is the average of these 5 scores — (8.0 + 9.0 + 7.0 + 5.0 + 5.0) ÷ 5 = 6.8.
Pros
- Repository describes the wallet as open source
- Built specifically for multi-chain EVM use
- Positions transaction safety as the core feature
Cons
- Neither a chain count nor hardware wallet support is stated in the README
- No swap fee is published in the documentation we checked
- Marketing site content did not render for verification, so claims come from the repository only
What the repository states
Rabby is described in its own repository as an open-source browser plugin for the DeFi ecosystem, providing a better-to-use and more secure multi-chain experience. The emphasis on transaction safety — showing what a signature will actually do — is the wallet's distinguishing claim.
What we could not verify
The marketing site did not return readable content when we checked it, and the repository README does not state a supported-chain count, hardware wallet compatibility, or any swap fee. Those gaps are why the wallet scores mid-table on three criteria despite a strong open-source position: we score what is published, and treat silence as silence rather than assuming the answer.
