DevLog 250327: Test Launch Results & NFT Display Debugging

Date: 2025-03-27
Project: TopSecurityNFT
Network: Polygon Amoy Testnet
Tooling: Foundry, Web3.Storage, OpenSea Testnet

Summary

Today marked a milestone with the successful test launch of the TopSecurityNFT contract on the Polygon Amoy testnet. Most of the collection minted and rendered correctly, and the entire collection was automatically indexed by OpenSea testnet without requiring any manual input.

However, there were a few visual bugs during testing. Specifically:

• Painting #4 and Painting #10 did not render on OpenSea.
• All other metadata files appeared valid and matched expected formatting.
• No syntax errors were detected in the JSON files, which makes this behavior somewhat ambiguous.

Debugging Notes

• Confirmed that all 10 tokens were successfully minted.
• Re-uploaded metadata to Web3.Storage to rule out CID or upload issues.
• Opened the metadata manually via IPFS gateway – files for Token 4 and 10 load as expected.
• Suspected potential casing mismatch or naming inconsistency between tokenURI() construction and actual file names.
• Considered image size or encoding errors as possible causes but could not reproduce locally.

Takeaways

• Thank god for testnet funds. Testing this without cost enabled full deployment and error identification before mainnet publishing.
• OpenSea indexing was automatic, which confirms the contract metadata structure is valid and conforms to standards.
• Foundry, IPFS, and Polygon are working well together in this workflow.
• Realized the importance of deterministic metadata generation and consistent image references.

Next Steps

• Start fresh with a new contract deployment tomorrow.
  • Reset the TopSecurityNFT contract to ensure clean indexing.
  • Regenerate all metadata files with fully verified naming and casing.
  • Upload to a new CID on Web3.Storage and update the baseURI.
• Mint tokens again on testnet and verify all images load correctly.
  • Focus specifically on image formatting and edge-case rendering bugs.
• If all tokens display correctly, proceed to prepare for mainnet deployment.

This session was a reminder that testnets exist for a reason—to break things safely. One more try, then it’s go-time for production.
