dvcrn Warren NFT - On-Chain NFT Collection Deployment
Deploy complete NFT collections with permanent on-chain image storage on MegaETH testnet. All images are stored using SSTORE2 bytecode storage in a WarrenContainer, and each collection gets its own NFT contract with minting support.
Network: MegaETH Testnet (Chain ID: 6343)
RPC: https://carrot.megaeth.com/rpc
Explorer: https://megaeth-testnet-v2.blockscout.com
How It Works
Your Images → SSTORE2 (on-chain) → WarrenContainer → WarrenLaunchedNFT
/images/1.png tokenURI renders
/images/2.png images on-chain
...
- Each image is deployed as a Page contract (fractal tree for >15KB images)
- All images are stored in a WarrenContainer NFT at
/images/1.png,/images/2.png, etc. - A WarrenLaunchedNFT contract is deployed referencing the container
- Minting is enabled and the collection is registered on megawarren.xyz
Setup (One Time)
cd {baseDir}
bash setup.sh
Get testnet ETH: https://docs.megaeth.com/faucet Genesis Key NFT auto-mints during first deployment (free on testnet).
Deploy NFT Collection
Option 1: From Image Folder
Prepare a folder with numbered images:
my-art/
├── 1.png
├── 2.png
├── 3.png
└── ...
Deploy:
cd {baseDir}
PRIVATE_KEY=0x... node deploy-nft.js \
--images-folder ./my-art/ \
--name "Cool Robots" \
--symbol "ROBOT" \
--description "100 unique robot NFTs on-chain" \
--max-supply 100
Option 2: Auto-Generate SVG Art
Generate unique SVG art programmatically:
cd {baseDir}
PRIVATE_KEY=0x... node deploy-nft.js \
--generate-svg 10 \
--name "Generative Art" \
--symbol "GART" \
--description "AI-generated on-chain art"
Full Configuration
PRIVATE_KEY=0x... node deploy-nft.js \
--images-folder ./collection/ \
--name "Cyber Punks" \
--symbol "CPUNK" \
--description "On-chain cyberpunk collection" \
--max-supply 1000 \
--whitelist-price 0.01 \
--public-price 0.02 \
--max-per-wallet 5 \
--royalty-bps 500

Troubleshooting
"No ETH" → Get testnet ETH from https://docs.megaeth.com/faucet
"GenesisKeyRequired" → Genesis Key auto-mints. If failing, check balance > 0.001 ETH
"Image exceeds 500KB" → Resize or compress images before deployment
"Too many images" → Maximum 256 images per container (TypeRegistry limit)
"TooManyFiles" → Same as above, reduce image count
DB registration warning → Non-critical. Collection still works on-chain. Management/mint pages will load from on-chain data.
