Web Wallet

Overview

Web wallets can connect users to custodial accounts, browser storage, hardware signers, embedded wallets, or smart-contract accounts. They offer easy access across devices and can integrate directly with web applications and payment flows.

Security depends heavily on origin and delivery. Phishing domains, compromised front-end code, malicious dependencies, browser extensions, cross-site attacks, and unsafe storage can change what users see or sign. HTTPS alone does not prove that the application is legitimate or uncompromised.

Users should use verified bookmarks, inspect the domain, protect the browser and device, and understand where keys and recovery authority reside. High-value signing should use independent hardware display or separated approval. Organizations need content-security controls, dependency review, secure deployment, monitoring, and incident rollback. Sessions and permissions should be minimal and revocable.

The Web Wallet workflow operates through several distinct states: request creation, user or policy approval, signature generation, network submission, execution, confirmation, balance recognition, and accounting. For Web Wallet, a wallet interface or provider response can report progress, but it cannot replace verified transaction and ledger evidence.

Material risks for Web Wallet include credential compromise, malicious destinations, unsupported assets, wrong-network transfers, stale balances, compromised software, provider outage, privacy leakage, and inaccessible recovery material. For Web Wallet, controls should reflect value, automation, reversibility, and whether the organization or a third party controls signing.

Production ownership for Web Wallet should identify the user or legal entity, supported assets and networks, address model, custody boundary, signing authority, recovery method, and systems permitted to request or observe transactions. For Web Wallet, these fields determine who can act and which evidence is authoritative.
