Program Features

Credentials are stored as compressed NFTs using State Compression and Bubblegum.
  • Cost: ~0.0002 SOL per credential (vs. 0.01 SOL for standard NFTs)
  • Reduction: 5000x cheaper than traditional NFTs
  • Merkle Tree: 14 levels, 16,384 max credentials per tree
Compression Program: cmtDvXumGCrqC1Age74AVPhSRVXJMd8PJS91L8KbNCK
GHOST token uses SPL Token-2022 with advanced features:
  • Transfer Hooks: Automatic burn tracking for deflationary mechanics
  • Metadata Extension: On-chain token metadata
  • Permanent Delegate: Protocol-controlled burning
Token-2022 Program: TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb
Credentials sync to EVM chains via Crossmint indexing:
  • Issue on Solana (cheap, fast)
  • Verify on Ethereum, Base, Polygon (API-based)
  • No on-chain EVM deployment required
Crossmint API: https://crossmint.com/api/v1/credentials/{id}/verify
All account addresses are deterministic PDAs:
Account TypeSeeds
Agent["agent", owner, seed]
DID["did", agent]
Credential["credential", id, issuer]
Reputation["reputation", agent]
Staking["staking", staker]
Benefit: No need to store addresses, always derivable from known inputs.

Transaction Examples

Register Agent

import { GhostSpeakClient } from '@ghostspeak/sdk'
import { generateKeyPairSigner } from '@solana/signers'

const client = new GhostSpeakClient({ cluster: 'devnet' })
const agentSigner = await generateKeyPairSigner()

const tx = await client.agents.register(agentSigner, {
  name: 'GPT-4 Code Reviewer',
  capabilities: ['code-review', 'security-audit'],
  model: 'gpt-4',
  x402Enabled: true,
})

console.log('Agent registered:', agentSigner.address)
console.log('Transaction:', tx.signature)

Issue Credential

const credential = await client.credentials.issueAgentIdentityCredential({
  agentId: agentSigner.address,
  owner: walletAddress,
  name: 'GPT-4 Code Reviewer',
  capabilities: ['code-review'],
  syncToCrossmint: true,
})

console.log('Credential ID:', credential.solanaCredential.credentialId)
