Next Steps - Quick Start Guide

Date: 2025-01-18
Purpose: Quick reference for executing all Next Steps

Overview

All Next Steps have been implemented. This guide provides quick instructions for execution.

---

Step 1: Configure Bridge Destinations

Prerequisites

1. Set ChainID 138 Selector:

   # Option 1: Use helper script to find selector
   ./scripts/configuration/find-chain-selector.sh
   
   # Option 2: Add to .env manually
   echo "CHAIN138_SELECTOR=<selector>" >> .env
   

   Note: See CHAIN138_SELECTOR_NOTES.md for selector information.

2. Ensure Admin Private Key:

   # Verify PRIVATE_KEY is set in .env
   grep PRIVATE_KEY .env
   

Execute Configuration

# Run bridge configuration script
./scripts/configuration/configure-bridge-destinations.sh

What it does:

• Configures ChainID 138 → Mainnet (both bridges)
• Configures Mainnet → ChainID 138 (if selector is set)
• Verifies configuration

Expected Output: Success messages for each bridge configuration.

Step 2: Deploy Off-Chain Services

State Anchoring Service

cd services/state-anchoring-service

# Install dependencies
npm install

# Build
npm run build

# Start service
npm start

Environment Variables (in .env or service .env):

PRIVATE_KEY=<admin-private-key>
TETHER_ADDRESS=0x15DF1D5BFDD8Aa4b380445D4e3E9B38d34283619
CHAIN138_RPC_URL=http://192.168.11.211:8545
MAINNET_RPC_URL=https://eth.llamarpc.com

Note: Validator signature collection needs implementation (placeholder exists).

Transaction Mirroring Service

cd services/transaction-mirroring-service

# Install dependencies
npm install

# Build
npm run build

# Start service
npm start

Environment Variables (in .env or service .env):

PRIVATE_KEY=<admin-private-key>
MIRROR_ADDRESS=0x4CF42c4F1dBa748601b8938be3E7ABD732E87cE9
CHAIN138_RPC_URL=http://192.168.11.211:8545
MAINNET_RPC_URL=https://eth.llamarpc.com
BATCH_INTERVAL_MS=60000

---

Step 3: Verify Configuration

Check Bridge Destinations

# Mainnet WETH9 Bridge
cast call 0x3304b747E565a97ec8AC220b0B6A1f6ffDB837e6 \
  "getDestinationChains()(uint64[])" \
  --rpc-url https://eth.llamarpc.com

# Mainnet WETH10 Bridge
cast call 0xe0E93247376aa097dB308B92e6Ba36bA015535D0 \
  "getDestinationChains()(uint64[])" \
  --rpc-url https://eth.llamarpc.com

Expected: Arrays should contain destination chain selectors.

Check Services

1. State Anchoring Service: Check logs for block processing
2. Transaction Mirroring Service: Check logs for transaction batching

---

Step 4: Execute Integration Testing

Follow the testing plan in TASK4_CROSS_CHAIN_TESTING_PLAN.md:

1. Phase 1: Configuration verification
2. Phase 2: Small amount test transfers
3. Phase 3: State synchronization testing
4. Phase 4: End-to-end integration tests
5. Phase 5: Edge cases and error handling

Prerequisites:

• Bridge destinations configured ✅
• Services running ✅
• Test accounts funded
• LINK tokens for CCIP fees

---

Step 5: Execute Performance Testing (Optional)

When system is operational and integration tests pass:

Follow TASK14_PERFORMANCE_TESTING_FRAMEWORK.md for:

• Throughput testing
• Latency testing
• Gas efficiency testing
• Concurrent load testing
• Stress testing

ChainID 138	To be determined (see CHAIN138_SELECTOR_NOTES.md)

Service Status

# Check if services are running
ps aux | grep -E "state-anchoring|transaction-mirroring"

# Check service logs
tail -f services/state-anchoring-service/logs/*.log
tail -f services/transaction-mirroring-service/logs/*.log

Troubleshooting

Bridge Configuration Fails

• Check PRIVATE_KEY is correct admin key
• Verify RPC endpoints are accessible
• Check ChainID 138 selector is set correctly

Services Won't Start

• Check PRIVATE_KEY is set
• Verify RPC endpoints are accessible
• Check npm dependencies are installed
• Review TypeScript compilation errors

Integration Tests Fail

• Verify bridge destinations are configured
• Check services are running
• Verify test accounts have funds
• Check LINK tokens are available for fees
