Deployment Details

Successful Deployment

• Address: 0x9a1D0dBEE997929ED02fD19E0E199704d20914dB
• Transaction: 0x4dc9f5eedf580c2b37457916b04048481aba19cf3c1a106ea1ee9eefa0dc03c8
• Method: forge create with --broadcast
• Gas Price: 20 gwei (20000000000 wei)
• Gas Limit: 10,000,000 (required for successful deployment)
• Status: ✅ Deployed and confirmed

Previous Attempts

• First attempt: Failed with 5M gas limit (hit gas limit, transaction reverted)
• Solution: Increased gas limit to 10M gas
• Result: ✅ Success

---

Key Fixes Applied

1. Script Fixes

• ✅ Added --broadcast flag to Method 2
• ✅ Added --gas-limit 10000000 (10M gas)
• ✅ Added RPC_URL validation and export
• ✅ Added on-chain verification for Method 1
• ✅ Script now properly tries all methods with verification

2. Gas Limit Issue

• Problem: 5M gas limit was insufficient
• Solution: Increased to 10M gas limit
• Result: Deployment succeeded

Lessons Learned

1. Gas Limit Critical: Contract deployment requires sufficient gas limit (10M for this contract)
2. Verification Important: Always verify on-chain deployment before reporting success
3. Multiple Methods: Having fallback deployment methods is essential
4. Export Variables: Ensure variables are exported for subshell access
