Strengths and weaknesses

In its favour

Pre-signing simulation showing exact balance changes
Automatic network switching and contract-risk warnings
Open source with no in-wallet token promotion

Against it

EVM only — no Bitcoin or Solana support
Smaller ecosystem means occasional dapp compatibility gaps

Prevention, not cleanup

Software wallets rarely lose funds because their cryptography failed. They lose funds because a user approved something they did not understand. Rabby simulates every transaction and displays the resulting balance changes and permission grants before you sign, so a hostile approval looks obviously hostile instead of looking like every other confirmation dialogue.

Warnings that are specific

Contracts flagged as malicious are called out, network switching is automatic, and the interface tells you which chain and which contract you are about to interact with. None of this is exotic engineering; it is the result of deciding that the wallet's job is to inform rather than to confirm.

No clutter, no house token

The client is open source and free of the promotional surface most wallets have accumulated. Nothing pushes you toward an in-house swap with a fee attached, which over time is worth more than any single feature.

The limit

EVM only. If you hold Bitcoin or Solana you will need a second wallet, and the ecosystem is smaller, so an occasional dapp expects MetaMask specifically.

How to set it up

Install it alongside MetaMask rather than instead of it, sign with a hardware wallet for anything meaningful, and review the simulated balance changes on every approval rather than only on unfamiliar sites. Familiar sites are where drainers get planted.

Frequently asked questions

Why is Rabby better than MetaMask?+

It simulates transactions and shows the exact balance changes and permissions before signing, warns on contracts flagged as malicious, and does not push in-house swaps. MetaMask has broader compatibility and non-EVM support through Snaps.

Is Rabby open source?+

Yes, the client is published under an open licence, and keys are held locally with no cloud backup enabled by default.

Does Rabby support Bitcoin or Solana?+

No. It is EVM-only, so holders of other chains need a second wallet alongside it.

How to read these tables

No paid placement. Nobody buys a position, a score or a mention. We take no affiliate commission on any link in this section, and operators do not see their score before it publishes.

Scores are read from the record. Each one is derived from the fact printed beside it — a published attestation, a contract, a register entry, an incident report — against bands that describe evidentiary states. Facts age: each table carries the date it was last verified, and this is not an audit.

Nothing here is financial advice. Crypto services fail, change terms and withdraw from markets without notice. Verify anything that matters directly with the provider, and tell us when we get something wrong.
