Applications Beyond Key Management

The same verifiable control plane can secure embedded wallets, agent wallets, company wallets, payments, and sensitive offchain workflows that need cryptographic accountability.

​

Abstract

Key management is the first application of the 0xkey verifiable foundations, not the last. Once a system can authenticate actors, evaluate policy, notarize state, parse intent, protect secrets, and produce signed evidence inside a trusted execution environment, it becomes a platform for many sensitive workflows. The common thread is delegated authority. Users delegate to apps, teams delegate to operators, businesses delegate to automation, and humans delegate to agents. 0xkey is designed to make that delegation explicit, scoped, revocable, and verifiable.

​

Embedded wallets

Embedded wallets ask infrastructure to disappear from the user perspective without disappearing from the security model. A user may authenticate with a passkey, email OTP, OAuth provider, or another familiar credential, while the application creates a wallet and enforces policies on behalf of that user. The 0xkey model separates product experience from wallet authority. The application can own the UI and onboarding flow, while enclave applications protect credential exchange, policy evaluation, wallet creation, and signing. This lets developers build consumer-grade UX without taking unilateral control of user assets.

​

Agent wallets

AI agents need wallets, but they should not be handed unrestricted private keys. A useful agent wallet is scoped by task, asset, chain, value, counterparty, time, approval threshold, and revocation rules. It can act autonomously inside a budget and escalate when policy says the risk is higher. 0xkey gives applications the building blocks for that model: machine credentials, policy expressions, consensus approvals, transaction-aware context, signed activity history, and high-speed signing inside an enclave. The result is not just a bot with a key. It is an actor with bounded cryptographic authority.

​

Policy-controlled payments

Payments require automation and restraint at the same time. Payroll, vendor payouts, stablecoin settlement, exchange operations, and recurring transfers all benefit from deterministic signing, policy limits, approval workflows, and clear audit records. With transaction-aware policy, a payment workflow can express whitelisted recipients, maximum transfer amounts, chain-specific constraints, approval requirements, and emergency denial rules. The policy can be enforced before a signature exists, which is the only moment when prevention is still possible.

​

Company wallets

Company wallets sit between individual self-custody and institutional custody. They need teams, roles, policy, auditability, and recovery. They also need to work across chains and account models without forcing every business process onchain. 0xkey lets a business represent users, wallets, private keys, policies, and approvals inside one organization model. Root quorum rules can protect administrative actions. Day-to-day operations can be delegated to scoped roles or services. High-risk flows can require additional approvals while routine flows remain fast.

​

Import, export, and recovery

Wallet infrastructure should not trap users. Secure import, export, and recovery are first-class requirements because applications often start with existing wallets or must provide an exit path for users and businesses. 0xkey approaches these flows with enclave-bound encryption. Key material can be encrypted to the trusted boundary for import, or encrypted from the trusted boundary to a client-held target key for export. The transport layer carries ciphertext and signed metadata; plaintext key material remains confined to the endpoints that are supposed to see it.

​

Toward verifiable compute

The same foundations that protect wallets can protect other sensitive workloads. If a workflow requires secret handling, external fetches, policy evaluation, signed decisions, or quorum-controlled code deployment, it can benefit from the enclave pattern. Over time, wallet infrastructure and verifiable compute converge. Agents will need to hold credentials, call APIs, evaluate risk, request approvals, and settle value. The long-term direction for 0xkey is to make those sensitive actions programmable without making them opaque.
