NFT Collections

Create NFT and multi-token collections with IPFS metadata, royalties, reveal mechanics, and batch minting.

IPFS Metadata

Permanent Storage: Files uploaded to IPFS cannot be deleted or modified. This is a feature, not a bug — it guarantees your NFT art and metadata are immutable and censorship-resistant.

ChainPortal uploads your NFT images and metadata to IPFS via Pinata:

{
  "name": "My NFT #1",
  "description": "A unique digital collectible",
  "image": "ipfs://QmXxx.../1.png",
  "attributes": [
    { "trait_type": "Background", "value": "Purple" },
    { "trait_type": "Rarity", "value": "Legendary" }
  ]
}

Files are validated server-side (magic-byte checking for PNG/JPEG/GIF/WebP/JSON) before upload.

ERC1155 Multi-Token

For collections where each token ID can have multiple copies (game items, event tickets, editions):

Each token ID has its own supply cap
Lower gas than deploying separate ERC721s
Batch transfers supported
Compatible with OpenSea and other marketplaces
