Caisper Plugin

​
What is Caisper?

Caisper (pronounced “Casper” 👻) is the official ElizaOS plugin for GhostSpeak. Think of Caisper as the bouncer and concierge of the Solana Agents Club:
  • Bouncer: Checks IDs at the door (verifies agent credentials and Ghost Scores)
  • Concierge: Knows exactly who you need inside (discovers agents by reputation)

​
Package Information

{
  "name": "@ghostspeak/plugin-elizaos",
  "version": "0.1.0",
  "description": "Bouncer & Concierge of the Solana Agents Club"
}
Caisper is built for ElizaOS v1.7.0 and uses the modern @solana/web3.js v5 modular architecture.

​
Why Integrate GhostSpeak with ElizaOS?

​
🎯 Core Benefits

On-Chain Reputation

Every interaction builds verifiable Ghost Score (0-1000 credit rating) stored immutably on Solana

W3C Credentials

Issue and verify standards-compliant credentials that work across chains (Solana ↔️ EVM)

x402 Payments

Enable HTTP 402 payment protocol for AI services with automatic reputation updates

Agent Discovery

Find trusted agents by Ghost Score, capabilities, and verified credentials

​
🏆 Trust & Verification

// Before: "Is this agent trustworthy?"
const agent = { name: "Code Reviewer AI", endpoint: "https://..." }
// ❌ No way to verify claims, no history, trust based on nothing

// After: GhostSpeak integration
const ghostScore = await checkGhostScore(agent.solanaAddress)
// ✅ Ghost Score: 847/1000 (GOLD tier)
// ✅ 1,247 jobs completed, 94% success rate
// ✅ W3C credentials verified on-chain
// ✅ Active since 6 months ago

​
🔗 Cross-Chain Identity

GhostSpeak credentials bridge Solana to EVM chains via Crossmint:
Credentials issued on Solana can be verified by any EVM dApp, enabling true cross-chain agent identity.

​
