Rabby
The wallet that treats transaction simulation as the core feature rather than a bolt-on. Rabby shows the expected balance change before you sign and flags known-malicious contracts, which addresses the way people actually lose money rather than the way they imagine they will. Holding and sending are free; swaps and bridges through Rabby carry a 0.25% fee built into the quote.

Non-custodial, MIT-licensed, keys never leave the device. Pre-signature simulation and malicious-contract flagging reduce the dominant real-world loss vector. Audited by SlowMist (August 2025) and Least Authority (2 September 2025; one medium-severity QR-sync issue left unresolved). The one loss on record, a Rabby Swap router exploit on 11 October 2022 (~$200,000), hit the swap contract, not the wallet; Rabby says it reimbursed users.
Holding and sending cost only gas. Rabby takes 0.25% on swaps and bridges routed through it (0% on wrapping), included in the quote rather than shown as a separate line; Gas Top Up carries a 20% service fee on small amounts.
Unlicensed software, as with everything in this category. Published by OPCODE LABS PTE. LTD., Singapore, from the DeBank team.
Accurate simulation across the major EVM chains, with automatic network switching that works.
Excellent for anyone who has used a wallet before. Assumes some familiarity — this is not the wallet for a first purchase.
Strengths
- Pre-signature simulation showing the actual balance change, which is the single most useful safety feature available
- Flags known-malicious contracts and risky approvals
- MIT-licensed code with two outside audits in 2025
Against it
- 0.25% fee on in-wallet swaps and bridges, folded into the quote
- EVM chains only — no Solana or Bitcoin
- Assumes prior familiarity with wallets
Built around how people actually lose money
Almost nobody loses crypto to broken cryptography. They lose it by approving a transaction that did something other than what they expected. Rabby simulates the transaction before you sign and shows the resulting balance change, and flags contracts already known to be malicious — addressing the actual loss vector rather than a theoretical one.
That is why it tops this table despite a smaller ecosystem than MetaMask. It is not free to trade through: swaps and bridges routed inside Rabby carry a 0.25% fee built into the quote. It is EVM-only and assumes prior familiarity; it is not the wallet for a first purchase, and it is the one to move to afterwards.
Frequently asked questions
What is transaction simulation and why does it matter?+
The wallet executes the transaction against current chain state before you sign and shows what your balances would actually become. It catches drainer contracts and malicious approvals at the only moment you can still stop them — the single most useful safety feature available in a software wallet.
Rabby or MetaMask?+
Rabby scores 8.3 against MetaMask’s 7.6, mostly on default safety behaviour and swap pricing: Rabby takes 0.25% on in-wallet swaps and bridges, MetaMask 0.875%. MetaMask is supported by essentially every application and now holds Solana and Bitcoin, which is worth something. Many people run both.
Is Rabby free?+
Installing, holding and sending cost only gas. Swaps and bridges through Rabby carry a 0.25% fee included in the quote (0% for wrapping ETH), and Gas Top Up carries a 20% service fee. Routing the same trade through a DEX front end and using Rabby only to sign avoids the 0.25%.
