You've already lost 3.2 STX on failed mainnet deployments. Testing on testnet:
- ✅ Costs nothing (free testnet STX from faucet)
- ✅ Validates the fix before spending more mainnet STX
- ✅ Finds any other issues in safe environment
- ✅ Builds confidence before mainnet deployment
This is the right decision! 🎯
-
Get a testnet wallet address:
# Generate or use existing testnet address # Or use: https://explorer.hiro.so/sandbox/faucet?chain=testnet
-
Request testnet STX from faucet:
- Visit: https://explorer.hiro.so/sandbox/faucet?chain=testnet
- Enter your testnet address
- Request STX (you'll get 500 testnet STX)
- Wait 1-2 minutes for confirmation

# Edit settings/Testnet.toml
# Add your testnet wallet mnemonic
nano settings/Testnet.tomlImportant: Use a testnet-only wallet/mnemonic, not your mainnet one!
# Deploy v5-ultra to testnet
clarinet deployments apply -p deployments/v5-ultra.testnet-plan.yamlExpected:
- Cost: 0 real STX (testnet only)
- Time: 2-10 minutes
- Result: Success or failure (we'll know if workaround works!)

- Test read-only functions:
- get-version (should return 5)
- get-min-stake-amount (should return 100)
- get-contract-owner
- get-total-staked (should be 0)
If basic deployment works, test the full flow:
- Stake minimum amount (100 microSTX = 0.0001 STX)
- Create proposal
- Vote on proposal
- Execute proposal after voting period
- Test admin functions:
- Update min-stake-amount
- Check new value
- Withdraw stake
This means:
- The workaround fixes the VM bug! 🎉
- Ready to deploy to mainnet with confidence
- Your micro-stake features will work
Next steps:
- Test all functions on testnet (30 mins)
- If everything works, deploy to mainnet
- Update frontend
- Launch! 🚀
Confidence for mainnet: HIGH (95%+)
This means:
- The VM bug is deeper than expected
- Even the workaround doesn't help
- Need different approach
Next steps:
- We have definitive proof of severe VM bug
- Deploy v4-minimal to mainnet (guaranteed to work)
- File critical bug report with Stacks team
- Launch with 10 STX min-stake for now
- Wait for Stacks team fix
- Deploy v6 with micro-stakes later
Confidence for v4-minimal: 99.9%
This means:
- Found a new issue before wasting mainnet STX
- Can fix it and try again on testnet
- Saved money by testing first!
Next steps:
- Analyze the new error
- Fix the issue
- Deploy to testnet again (free!)
- Repeat until it works
| Step | Network | Cost |
|---|---|---|
| Already spent | Mainnet | 3.2 STX |
| Test v5-ultra | Testnet | 0 STX (free) |
| If works → Deploy | Mainnet | 0.8 STX |
| Total | 4.0 STX |
| Step | Network | Cost |
|---|---|---|
| Already spent | Mainnet | 3.2 STX |
| Try v5-ultra | Mainnet | 0.8 STX |
| If fails → Try v5-ultra v2 | Mainnet | 0.8 STX |
| If fails → Try v5-ultra v3 | Mainnet | 0.8 STX |
| Finally → Deploy v4-minimal | Mainnet | 0.8 STX |
| Total | 6.4 STX |
You're saving 2.4 STX by testing on testnet first! 💰

Testnet Testing:
- Get testnet STX: 2 minutes
- Configure wallet: 2 minutes
- Deploy contract: 5-10 minutes
- Basic verification: 5 minutes
- Total: ~20 minutes
If Successful:
- Full testing: 30 minutes
- Deploy to mainnet: 10-30 minutes
- Total to launch: ~1 hour
If Failed:
- Analyze error: 10 minutes
- Decide next approach: 5 minutes
- Deploy v4-minimal to mainnet: 30 minutes
- Total to launch: ~45 minutes
Do this now:
- ✅ Get testnet STX from faucet (2 mins)
- ✅ Update settings/Testnet.toml with your testnet mnemonic (2 mins)
- ✅ Deploy v5-ultra to testnet (5-10 mins)
- ✅ Check if it works
Then decide:
- ✅ If works: Deploy to mainnet with confidence
- ❌ If fails: Deploy v4-minimal to mainnet (guaranteed)
Setting up testnet wallet:
- Use Hiro Wallet extension
- Create new account
- Switch to Testnet mode
- Get your address
- Request STX from faucet
Configuring Testnet.toml:
- Copy your testnet wallet's mnemonic
- Paste into settings/Testnet.toml
- Save file
- Deploy!
Testnet testing = FREE validation before spending more mainnet STX
You've already spent 3.2 STX. Let's make sure v5-ultra works before spending another 0.8 STX!
