🔑 Key Takeaway: Small balances still need unique secrets and phishing resistance. Start simple, but keep habits that scale: unique seeds, careful signing, offline backups.

User Profile

A user with foundational web3 knowledge who is actively learning and interacting with dApps. The asset value is typically non-critical, where a potential loss would not be financially significant. This profile prioritizes ease of use and learning over protections against online threats.

Primary Goal

The primary objective is a low-friction setup for convenience and dApp interaction. This includes frequent transactions, exploring DeFi protocols, and engaging with NFTs.

Recommended Setup

The standard setup for this profile is a hot wallet, which provides the necessary internet connectivity for active use. The most common types are:

Browser Extension Wallets: Integrate directly into a web browser for seamless dApp interaction.
Mobile Wallets: Applications installed on a smartphone, offering convenience and on-the-go access.
Desktop Wallets: Software applications installed on a computer, which can sometimes offer more advanced features than mobile or browser counterparts.

Key Considerations & Trade-offs

While convenient, this setup carries inherent risks that the user must understand and accept.

Online Threat Vector: As hot wallets are internet-connected, they are inherently vulnerable to malware and exploits targeting the browser or operating system.
Supply Chain Risk: It is critical to download wallet software only from official, verified sources.

How to Select a Wallet

When selecting a wallet, prioritize those whose code is open-source, as this allows for public scrutiny and independent verification by the security community. For users who are not developers, several platforms provide independent analysis to help evaluate a wallet's security.

For example, Wallet Scrutiny focuses on verifying if a wallet's code is verifiably open-source. Others, like Wallet Security Ranking, provide a security score based on specific criteria such as transaction clarity, protection against known threats, and how it handles dApp permissions.

Using these tools can provide valuable data points to help you assess a wallet's security posture and make an informed decision.

Security Best Practices

Strong Password: Use a strong, unique password. Do not reuse passwords from other accounts.
Antivirus Software: Install antivirus on the device used for wallet access, since hot wallets are exposed to browser and operating system malware.
Minimal Auto-Lock Time: Set auto-lock to 5-15 minutes. Shorter timers limit exposure if unattended and reduce how long decrypted keys stay in memory.
Dedicated Browser Profile: Use a separate browser profile for wallet and dApp use, isolated from the extensions and sites you use for general browsing.
No Browser Sync: Keep extensions out of browser sync. Sync can auto-install extensions across devices, so one malicious extension can spread to every synced device.
Minimal Browser Extensions: Keep extensions to a minimum. Each one is added attack surface, a compromised extension can script wallet popups and alter or intercept transactions.
No Wallet Exposure on Calls: Never unlock or reveal a hot wallet during screen shares or remote calls. Attackers use fake support calls to capture passwords or seed phrases the moment they're visible.
