🌟 Wallet4Agent — Use Cases

How AI Agents Establish Trust With Humans, Companies, Services, and Other Agents

Wallet4Agent provides a trust layer for AI Agents.
With it, an agent can prove:

• Who it is (identity)
• Who owns or controls it (delegation)
• What it is allowed to do (permissions)
• What trustworthy information it holds (credentials)
• Who it is interacting with (verification of users, companies, APIs, or other agents)

This unlocks a new class of trusted autonomous interactions, enabling AI agents to safely operate in real-world environments.

1. 🤝 Why Trust Matters for AI Agents

AI Agents are increasingly capable — but without trust, they remain limited:

• They cannot safely access user data
• They cannot act on behalf of a person or company
• They cannot authenticate to services
• They cannot collaborate with other agents
• They cannot make verifiable statements or signatures

Trust is the missing layer.

Wallet4Agent gives AI agents a verifiable identity and a wallet of credentials, allowing them to operate as secure, accountable digital actors.

2. 🔐 What Wallet4Agent Enables

With Wallet4Agent, AI Agents can establish trust relationships with:

🧑 Natural Persons

• Verify user identity
• Receive consent or delegation
• Act on behalf of a person with clear boundaries

🏢 Companies

• Receive corporate identity credentials
• Act as a corporate representative or service agent
• Execute workflows with enterprise authorization

🤖 Other Agents

• Authenticate each other using OIDC4VP
• Exchange data safely
• Validate roles, capabilities, or mandates

🌐 Services / APIs

• Present verifiable credentials instead of API keys
• Access regulated or sensitive systems
• Act within enforced scopes and boundaries

All these scenarios share the same trust primitives.

3. 🧱 Core Trust Primitives

Although many use cases exist, all rely on just three fundamental flows.

3.1 🪪 Identity Verification

The Agent verifies the identity of:

• A natural person (email verification → user identity proof)
• A company (corporate credentials)
• Another AI agent (agent authentication flow)

This proves:
“I know who I am interacting with.”

Tools involved:
- start_user_verification
- poll_user_verification
- start_agent_authentication
- poll_agent_authentication

3.2 🔏 Delegation & Mandates

A person or company grants an agent verifiable authority to:

• Represent them
• Act within defined limits
• Sign or negotiate
• Access specific resources
• Use data or APIs

Example:
A user authorizes their Agent to negotiate a price up to 100€.

Delegations are issued as Verifiable Credentials and stored in the agent’s wallet.

3.3 📩 Verifiable Presentations Access

When interacting with a service or another agent, the AI Agent presents:

• Verified identity
• Delegation proofs
• Required credentials

This enables:

• API access
• Consent-based operations
• Data sharing
• Contract signatures
• Workflow execution

This proves:
“I am allowed to do this.”

4. 💡 High-Impact Use Cases

Below are the strongest, most concrete examples of what Wallet4Agent enables.

4.1 🧑‍💼 Personal AI: Your Trusted Digital Representative

A user wants their AI agent to:

• Access their calendar
• Negotiate prices
• Book appointments
• Handle paperwork
• Sign agreements
• Share their verified information when needed

How trust is established:

1. User verification
2. User issues permissions (VC)
3. Agent stores them in its wallet
4. Agent presents proofs to services or agents
5. Every action is logged and auditable

Real-world examples:

• A travel agent AI books a trip using verified identity & payment authorization
• A negotiation bot proves spending authorization
• A health assistant presents age / identity proofs without exposing full data

Personal AI stops being a toy —
it becomes a trusted digital extension of the user.

4.2 🏢 Enterprise AI Agent With Corporate Identity

A company wants an AI agent to perform operations such as:

• Managing supplier communication
• Answering customer email
• Handling HR onboarding tasks
• Reviewing or signing internal documents
• Making pre-approved purchases

Corporate trust flow:

1. Company identity is verified
2. Company issues a corporate mandate credential
3. Agent acts with that mandate
4. Internal systems validate credentials before granting access

Examples:

• AI Purchasing Agent with a “Buy up to 500€” delegated credential
• AI HR Agent verifying candidate documents
• AI Compliance Agent verifying transactions

This brings enterprise-grade trust to autonomous workflows.

4.3 🏦 Regulated API Access Without API Keys

Agents need to access APIs that require trust:

• Banking APIs
• Insurance APIs
• Government services
• Healthcare infrastructure

API keys are insecure and unscoped.
Instead, the agent presents a Verifiable Presentation with:

• Agent identity
• Delegation from the user/company
• Required attributes

Example flow:

1. User delegates access to “view my bank balance”
2. Agent receives a VC for that right
3. Agent queries the bank API
4. Bank validates the VP and returns the data
5. Everything is recorded and revocable

The service no longer trusts the application,
it trusts the agent and its credentials.

4.4 🤖🤝🤖 Agent-to-Agent Trust (Distributed Agent Networks)

When two autonomous agents collaborate, they must verify:

• Identity
• Roles
• Capabilities
• Delegations
• Intent

Wallet4Agent provides an OIDC4VP verification flow.

Example:

• Company A agent requests a quote from Company B agent
• Both agents mutually authenticate
• They exchange only verifiable, scoped data
• They negotiate automatically

This unlocks a world of trusted multi-agent ecosystems.
