# VerificationBadge

**Slug:** `verification-badge`  
**Import:** `import { VerificationBadge } from "@p4n/erc8004-ui"`

> **NOTE — unofficial library.** `@p4n/erc8004-ui` is an independent, community-built project. It is not affiliated with, maintained by, or endorsed by the authors of ERC-8004. It reads the standard's on-chain data through public subgraphs; it does not speak for the standard.

## Description

Compact inline badge showing the agent's verification tier derived from completed validations and average validation score.

## Caveats

> **Warning:** The Validation Registry contract is recorded at the zero address on every chain checked — testnets included — so this component renders its empty state everywhere. Verified 2026-09-04 across Ethereum, Base, Polygon, BNB Smart Chain, BNB Chapel and Base Sepolia. See [Concepts › Validation Registry](https://erc8004-ui.vercel.app/docs/concepts#validation-registry).

## Usage

```tsx
import { VerificationBadge } from "@p4n/erc8004-ui"
<VerificationBadge agentRegistry="eip155:8453:0x8004A169FB4a3325136EB29fA0ceB6D2e539a432" agentId={888} />
```

## Examples

### Alongside Agent Name

Place next to an agent name for inline trust indication.

```tsx
<AgentProvider agentRegistry="eip155:8453:0x8004...a432" agentId={888}>
  <div className="flex items-center gap-2">
    <AgentName />
    <VerificationBadge />
  </div>
</AgentProvider>
```

### Standalone

Used alone as a compact trust indicator anywhere in the UI.

```tsx
<VerificationBadge agentRegistry="eip155:8453:0x8004...a432" agentId={888} />
```

## In Context

VerificationBadge in a trust panel with validation score and recent validations.

```tsx
<AgentProvider agentRegistry="eip155:8453:0x8004...a432" agentId={888}>
  <div className="flex items-center gap-2">
    <AgentName />
    <VerificationBadge />
  </div>
  <ValidationScore />
  <ValidationList pageSize={3} />
</AgentProvider>
```
