Testing Guide: Devnet Strategies for GhostSpeak

Testing on Solana devnet allows you to validate your GhostSpeak integration before deploying to mainnet. This guide covers testing agents, credentials, Ghost Score, marketplace transactions, and common troubleshooting scenarios.

Devnet Only: Never use production secrets, real funds, or sensitive data on devnet. Devnet is reset periodically and is not stable for production workloads.

Devnet Setup

Step 1: Environment Configuration

Create a separate devnet configuration:

.env.devnet

# Solana
SOLANA_CLUSTER=devnet
SOLANA_RPC_URL=https://api.devnet.solana.com
WALLET_PATH=~/.config/solana/devnet-keypair.json

# GhostSpeak
GHOSTSPEAK_CLUSTER=devnet
GHOSTSPEAK_PROGRAM_ID=GhostDevProgram...

# Crossmint (staging for devnet)
CROSSMINT_API_KEY=sk_staging_...
CROSSMINT_ENVIRONMENT=staging

# Testing
TEST_AGENT_COUNT=10
SIMULATE_TRANSACTIONS=true

Step 2: Get Devnet SOL

# Generate devnet wallet if needed
solana-keygen new --outfile ~/.config/solana/devnet-keypair.json

# Request devnet SOL from faucet
solana airdrop 2 --url devnet --keypair ~/.config/solana/devnet-keypair.json

# Verify balance
solana balance --url devnet --keypair ~/.config/solana/devnet-keypair.json

# If faucet is rate-limited, use alternatives:
# - QuickNode: https://faucet.quicknode.com/solana/devnet
# - SolFaucet: https://solfaucet.com

Devnet Faucet Limits: Most faucets allow 2-5 SOL per request with a 24-hour cooldown. Plan accordingly for high-volume testing.

Testing Workflows

Test 1: Agent Registration

__tests__/agent-registration.test.ts

import { describe, test, expect, beforeAll } from 'bun:test'
import { GhostSpeakClient } from '@ghostspeak/sdk'
import { generateKeyPairSigner } from '@solana/signers'

describe('Agent Registration', () => {
  let client: GhostSpeakClient
  let wallet: any

  beforeAll(async () => {
    client = new GhostSpeakClient({
      cluster: 'devnet',
      commitment: 'confirmed',
    })

    wallet = await loadTestWallet()
  })

  test('should register agent successfully', async () => {
    const agentSigner = await generateKeyPairSigner()

      name: 'Test Agent',
      description: 'Testing agent registration',
      capabilities: ['test'],
      model: 'test-model',
    })

    expect(agent.address).toBeDefined()
    expect(agent.signature).toBeDefined()

    // Verify agent exists on-chain
    const fetchedAgent = await client.agents.getAgent(agentSigner.address)

        name: 'Duplicate Agent',
        capabilities: ['test'],
      })
    ).rejects.toThrow('Agent already registered')
  })

  test('should handle insufficient funds gracefully', async () => {
    // Create wallet with 0 SOL
    const emptyWallet = await generateKeyPairSigner()

    await expect(
      client.agents.register(emptyWallet, {

      syncToCrossmint: false, // Skip cross-chain for faster tests
    })

    expect(result.solanaCredential.credentialId).toBeDefined()
    expect(result.solanaCredential.issuer).toContain('did:sol:devnet')
    expect(result.solanaCredential.subject).toContain(agentSigner.address)
  })

  test('should verify issued credential', async () => {

Load Testing

Troubleshooting Common Issues

Transaction simulation failed

Error: “Transaction simulation failed: Blockhash not found”Solution: Devnet is unstable. Retry with increased commitment level:

const client = new GhostSpeakClient({
  cluster: 'devnet',
  commitment: 'finalized', // Use 'finalized' instead of 'confirmed'
})

Devnet faucet rate-limited

Error: “Faucet request failed: Rate limit exceeded”Solution: Use alternative faucets or wait 24 hours:

# QuickNode faucet
curl -X POST https://faucet.quicknode.com/solana/devnet \
  -H "Content-Type: application/json" \
  -d '{"address":"YOUR_ADDRESS"}'

Agent registration hangs

Error: Transaction never confirmsSolution: Check devnet RPC status and increase timeout:

const agent = await client.agents.register(agentSigner, {
  name: 'Test Agent',
  capabilities: ['test'],
}, {
  timeout: 120000, // 2 minutes
  maxRetries: 3,
})

Credential verification fails on cross-chain

Error: “Credential not found on Ethereum”Solution: Crossmint indexing takes 30-60 seconds on devnet/staging:

// Wait for indexing
await new Promise(resolve => setTimeout(resolve, 60000))

// Then retry
const verification = await verifyOnEthereum(credentialId)
