Deployment Rehearsal

Back to Production Readiness

Follow this progression to catch issues at each stage:

Stage 1: Local Neo-Express

# Create a fresh chain
NEOXP=./build/dotnet-tools/neoxp
$NEOXP create -f -o chain.neo-express
$NEOXP transfer -i chain.neo-express 100 GAS genesis node1

# Deploy
$NEOXP contract deploy -i chain.neo-express build/contract.nef node1

# Test every public method
# Test every event emission
# Test error conditions (require failures, access control)
# Test constructor arguments if applicable
# Test contract update if applicable

Stage 2: Neo N3 TestNet

1. Obtain test GAS from the Neo TestNet faucet.
2. Deploy the exact same .nef and .manifest.json files.
3. Run the same test scenarios as local.
4. Verify transaction results on a Neo block explorer.
5. Test with multiple accounts and concurrent transactions.

Stage 3: Neo N3 MainNet

1. Verify the contract hash matches your prediction.
2. Deploy with a funded MainNet account.
3. Start with small-value transactions to verify behavior.
4. Monitor the contract for unexpected behavior.
