About

WalletOS is an agentic intelligence layer for crypto wallets. It gives users a way to connect their existing AI agent, such as Codex or Claude Code, to their wallets and dApps so the agent can understand context, investigate on-chain activity, recommend actions, and prepare transactions for user approval. Instead of building another wallet with a closed AI assistant, WalletOS turns the user’s own agent into the intelligence layer of the wallet. The agent can use installable WalletOS Skills for tasks such as transaction security, portfolio analysis, protocol research, risk management, and rebalancing. Our first skill focuses on transaction safety. When a user interacts with an unfamiliar dApp, WalletOS can provide the agent with the page context, contract interaction, calldata, and wallet request so it can compare what the website claims will happen with what the transaction will actually do. This helps users understand risky approvals, deceptive signatures, phishing flows, cloned protocols, and potential wallet-drain behavior before they approve anything. WalletOS also supports proactive financial workflows. An agent can analyze positions across wallets, identify concentration or idle capital, research protocols, recommend a rebalance, and prepare the required transactions for the user to review and approve. Sponsor technologies extend the agent’s capabilities: The Graph provides on-chain intelligence for protocol and wallet research, Ledger strengthens the security and trusted signing workflow, and Privy enables agentic wallet and execution use cases. The long-term vision is an open marketplace of Web3 agent skills, similar to extensions for an IDE, where developers can publish reusable capabilities and the user’s AI agent decides when and how to use them. Your wallet provides custody. Your agent provides intelligence. WalletOS connects both.

How it's made

WalletOS is built as a browser extension + local desktop runtime. The extension captures dApp and wallet context, while the desktop companion runs local agents such as Codex and gives them access to WalletOS Skills. The key idea is the runtime: instead of hard-coding every blockchain integration into the app, WalletOS loads plugins/skills that tell the agent which tools to use for a task. A skill can combine CLIs, MCPs, APIs, and scripts, so new capabilities can be added without changing the core app. For example, our security skill uses Foundry tools such as Cast and Anvil to decode and simulate transactions. The Graph is used by research and portfolio skills to query on-chain protocol and wallet data. Ledger is integrated into the security and signing flow, including local testing with Speculos. Privy is used for agentic wallet and execution workflows. The most hacky part is that WalletOS does not run its own AI model. It launches the user’s existing local agent and turns it into a wallet-specialized agent by giving it runtime context plus installable Web3 skills. This lets us keep the core lightweight while making the system extensible across many protocols and partner technologies. BROWSER EXTENSION ↓ AGENT RUNTIME ↓ PLUGIN MARKETPLACE ↓ WALLET ACTIONS
