# ERC-8004 Identity

BV-7X is registered as a trustless agent on Base mainnet using the ERC-8004 standard. This provides verifiable on-chain identity and a transparent reputation history.

***

## What Is ERC-8004?

ERC-8004 is an on-chain standard for AI agent identity and reputation. It provides:

* **Identity**: A unique agent ID tied to a wallet address, with metadata (name, description, capabilities)
* **Reputation**: A public feedback log where outcomes (wins, losses) are recorded on-chain
* **Discoverability**: Other agents and protocols can look up any registered agent by ID

## BV-7X Agent

| Field                  | Value                                        |
| ---------------------- | -------------------------------------------- |
| **Agent ID**           | 28841                                        |
| **Chain**              | Base (8453)                                  |
| **Wallet**             | `0xd8B71d23e1a8da9867497C0E757A1143B94C3e1e` |
| **IdentityRegistry**   | `0x8004A169FB4a3325136EB29fA0ceB6D2e539a432` |
| **ReputationRegistry** | `0x8004BAa17C55a88189AE136b182e5fdA19dE9b63` |

## How Reputation Is Logged

After each Polymarket wager settles, BV-7X automatically logs the outcome to the ReputationRegistry:

1. The settlement cron detects a resolved wager
2. It determines the outcome (WIN or LOSS)
3. It calls `giveFeedback()` on the ReputationRegistry with the result
4. The feedback is permanently recorded on-chain

This creates an immutable, auditable track record. Anyone can query the ReputationRegistry to see the agent's full history of predictions and outcomes.

## Verifying On-Chain

You can verify the agent's identity and reputation directly on Base:

1. Go to [Basescan](https://basescan.org)
2. Navigate to the IdentityRegistry contract (`0x8004A169FB4a3325136EB29fA0ceB6D2e539a432`)
3. Call `getAgent(28841)` to see the registered identity
4. Navigate to the ReputationRegistry (`0x8004BAa17C55a88189AE136b182e5fdA19dE9b63`)
5. Call `getFeedback(28841)` to see the full reputation history

## Agent Card

The agent's capabilities are also published at:

```

```

This JSON file follows the A2A standard and includes references to the ERC-8004 registration, MCP server, and OpenAPI spec.
