Web3 Wallet

Overview

Beyond transfers, Web3 wallets commonly support application connections, contract calls, token approvals, typed-data signing, network switching, collectibles, decentralized finance, and identity functions. They may be self-custodial, custodial, embedded, hardware-backed, or smart-contract based.

Broad application capability expands attack surface. Malicious contracts, phishing, blind signing, unlimited allowances, chain confusion, and persistent sessions can create future authority without immediate movement. A wallet can correctly execute a dangerous request supplied by a compromised application.

Users should verify application origin and review network, contract, method, recipient, asset, amount, allowance, and expiry for every request. Permissions and sessions need periodic revocation. Organizations should separate high-value assets from exploratory activity and use simulation, allowlists, and hardware signing where appropriate. Activity must be monitored beyond simple transfers.

Material risks for Web3 Wallet include credential compromise, malicious destinations, unsupported assets, wrong-network transfers, stale balances, compromised software, provider outage, privacy leakage, and inaccessible recovery material. For Web3 Wallet, controls should reflect value, automation, reversibility, and whether the organization or a third party controls signing.

The Web3 Wallet workflow operates through several distinct states: request creation, user or policy approval, signature generation, network submission, execution, confirmation, balance recognition, and accounting. For Web3 Wallet, a wallet interface or provider response can report progress, but it cannot replace verified transaction and ledger evidence.

Web3 Wallet 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.
