Audit-grade crypto product comparisons for developers

To connect your wallet to a decentralized application (dApp): 1) Visit the dApp website, 2) Click "Connect Wallet" button, 3) Select your wallet from the list (e.g., MetaMask, Rabby), 4) Approve the connection in your wallet popup, 5) Review and confirm any permissions. Always verify you're on the correct website before connecting.

Hot wallets are connected to the internet (browser extensions, mobile apps) and are convenient for daily use. Cold wallets (hardware wallets) store keys offline, providing maximum security for long-term storage. For best security, use hot wallets for small amounts and cold wallets for larger holdings.

A seed phrase (recovery phrase) is a 12-24 word sequence that can restore your wallet if you lose access. It's the master key to all your funds. NEVER share it with anyone, store it offline in multiple secure locations, and never enter it on any website. Anyone with your seed phrase can steal all your assets.

Look for: 1) Open source code that can be audited, 2) Third-party security audits, 3) Active development and bug bounties, 4) Strong track record without major hacks, 5) Good reputation in the developer community. Our comparison tables score these factors for each wallet.

Transaction simulation shows you exactly what will happen before you sign a transaction—which tokens will leave/enter your wallet, gas costs, and potential risks. Wallets like Rabby offer this feature to help you avoid scams and mistakes. It's especially valuable when interacting with unfamiliar contracts.

Red flags include: 1) Requests for your seed phrase, 2) Fake wallet apps/extensions, 3) Phishing sites mimicking official wallets, 4) Unsolicited DMs offering help, 5) "Customer support" asking for private keys. Always download wallets from official sources and never share your seed phrase.

Wallet Radar is a developer-first platform for comparing crypto access products, especially wallets, cards, and ramps. We provide evidence-based scoring using GitHub activity, security audits, release frequency, and developer experience metrics. All data is public, verifiable, and any commercial links should be disclosed clearly.

Wallet Radar is a research site, not a broker or wallet provider. We do not run login pages, wallet connections, or transaction signing. The data is sourced from public information and should be independently verified before making financial decisions.

Scores are generated from the visible comparison-table columns, not hand-tuned after the fact. Each category uses a published weighting model that turns inputs like custody, fees, platform coverage, activity, audits, and developer UX into a reproducible 0-100 score.

For EVM development, Rabby is still the strongest daily-driver because it combines transaction simulation, scam alerts, and cross-platform coverage. For compatibility testing, keep MetaMask in the matrix. For higher-assurance signing, pair your software wallet with a dedicated hardware wallet.

EIP-7702 allows regular accounts (EOAs) to temporarily act like smart contract wallets, enabling features like gas sponsorship, batched transactions, and social recovery without migrating to a new address. Wallets supporting 7702 offer the best of both worlds.

EOA (Externally Owned Account) wallets are controlled by a private key—simple but limited. Smart contract wallets (like Safe) are programmable, offering features like multi-sig, spending limits, and social recovery. Account abstraction (ERC-4337) brings smart wallet benefits to more users.
