Successful Deployment

  • Address: 0x9a1D0dBEE997929ED02fD19E0E199704d20914dB
  • Transaction: 0x4dc9f5eedf580c2b37457916b04048481aba19cf3c1a106ea1ee9eefa0dc03c8

  • 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

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
