Wallet Client

Overview

The client may hold keys locally, connect to hardware signers, access a custodian, or control a smart-contract wallet. It can construct transactions, show balances, manage connections, and send signed transactions to nodes or backend services.

Security depends on more than where keys reside. A malicious client can display a false recipient, request broad permissions, leak metadata, or replace unsigned transaction data. Browser and mobile clients also depend on operating systems, extensions, update channels, and third-party libraries.

Users should verify software origin, version, publisher, and integrity, then keep it supported and protected. High-value transactions benefit from a trusted signing display that independently shows canonical details. Organizations should manage deployment, device access, configuration, and logs. Client requests, signatures, broadcasts, and final settlement must remain linked for monitoring and reconciliation.

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

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

Wallet Client should be distinguished from the asset balance and from the application that displays it. For example, a customer-facing success message does not prove that the intended transaction executed on the correct network; operations should verify execution and reconcile the result before irreversible fulfillment.
