Hey Conflux community!
I’m Syv, and I’m excited to share progress on AstrumGate — our omnichain NFT bridge built during the Summer Hackfest 2025 (Code Without Borders track).
What it does
AstrumGate is a symmetric cross-chain NFT bridge powered by LayerZero (using the ONFT721 pattern) that lets ERC-721 NFTs move seamlessly between Conflux eSpace, Base, and Arbitrum — preserving full metadata (name, symbol, tokenURI) without traditional wrapping friction. It’s live on mainnets for real-world testing!
Key features in the current prototype:
- Permissionless registration of any ERC-721 collection
- Automatic dynamic wrapper deployment on target chains
- Lock/unlock on source + mint/burn on destination
- Integrated NFT Collection Factory (clone-based ERC721) with batch minting/burning
- Bridge history tracking in the frontend
Repo: https://github.com/0xfdbu/astrumgate/
(Contracts are deployed on mainnet for demo purposes — see README for addresses)
We need your help to level it up!
The project is still a hackathon prototype — experimental and not production-ready. We’re actively looking for devs, testers, and security-minded folks to:
- Try bridging dummy NFTs and break things
- Spot edge cases, bugs, or UX friction
- Review bridge logic for potential vulnerabilities
- Share thoughts on latency, gas usage, and overall flow
CRITICAL SAFETY WARNING
Do NOT bridge any real-value or mainnet NFTs! This is unaudited experimental code — use only test/dummy assets to avoid any risk. Note: Since it’s deployed on mainnets (Conflux eSpace, Base, Arbitrum), creating collections and minting/bridging will incur real gas fees. Use a burner wallet with minimal funds for testing.
How to test safely (takes ~5 minutes):
- Go to our collection creator: https://astrumgate.vercel.app
(Create a test collection — incurs mainnet gas fees, so keep it minimal) - Mint some dummy NFTs on Conflux eSpace (use a burner wallet with small amounts of CFX/ETH for gas)
- Head to the prototype bridge UI (linked in repo README)
- Bridge your test NFTs to/from Base or Arbitrum and observe the process
What feedback would be super valuable:
- Security red flags in the ONFT / LayerZero integration
- Any confusing steps in mint → bridge flow
- Real-world latency & fee experience
- Suggestions for improvements (UI, gas opt, error handling, etc.)
Drop your thoughts, screenshots, bug reports, or questions below — or DM me / open an issue on GitHub. Every bit of feedback helps make cross-chain NFTs better for Conflux and beyond!
Thanks in advance, let’s build together 
Syv
