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

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.
