Plugin: AgentFolio trust scores + on-chain identity for Eliza agents

[0xbrainkid]

Idea

Eliza agents currently lack a standardized way to prove their identity or reputation to other agents/services they interact with. As multi-agent systems grow, verifiable identity becomes critical.

Proposal

Build an @elizaos/plugin-agentfolio that gives every Eliza agent:

• Verified on-chain identity via SATP (Solana Agent Trust Protocol)
• Trust score — computed from verified credentials (GitHub, X, domain, wallet)
• Discoverable profile on agentfolio.bot

Plugin scope

// plugin-agentfolio
export const agentfolioPlugin: Plugin = {
  name: 'agentfolio',
  actions: [
    checkTrustScore,      // Query another agent's trust score before interacting
    verifyIdentity,       // Prove this agent's identity to a counterparty
    updateProfile,        // Sync agent capabilities/bio to AgentFolio
  ],
  providers: [
    trustScoreProvider,   // Inject trust context into agent decisions
  ]
};

Use cases

1. Agent-to-agent trust — before delegating a task, check the other agent's trust score
2. DeFi agent reputation — trading agents prove track record via on-chain identity
3. Auto-registration — when an Eliza agent starts, it auto-registers on AgentFolio

• SATP: Solana on-chain agent identity standard

Happy to build the plugin and submit a PR. Eliza's plugin architecture makes this clean to implement.
