The most expensive mistake in self-custody is not a broken cipher, it is a signature the user did not understand. Rabby's central feature is a direct answer to that: before you approve anything, the wallet simulates the transaction and tells you, in plain terms, which balances will move and which permissions you are granting.

In a month of testing across seven chains it flagged two approvals we would otherwise have signed without much thought, including an unlimited allowance to a contract we had no ongoing relationship with. The allowance manager then made revoking a batch of historic approvals a two-minute job rather than an afternoon.

Quality-of-life details compound. Rabby detects the network an application expects and switches automatically, eliminating the failed-transaction loop that produces a large share of new-user support tickets. Gas estimation was accurate throughout, and hardware wallet pairing worked with both devices we tried.

The limits are honest ones. This is an EVM wallet, so Bitcoin and Solana holders need something alongside it, and a small number of applications still hand it an awkward connection prompt. Neither is a reason to keep signing blind elsewhere.

Four point six stars, and the highest score we have given a free wallet. Every competitor should ship this preview.
