IPFS Integration

NFT metadata and assets are stored on IPFS via Pinata:

POST /api/ipfs/upload-metadata
{
"name": "My NFT",
"description": "A unique piece", "image": "ipfs://Qm...",
"attributes": [...]
}

Response:

{
"success": true, "cid": "Qm...",
"uri": "ipfs://Qm..."
}

NFT Metadata Standard

Both EVM and Solana NFTs follow compatible metadata:

{
"name": "NFT Name",
"symbol": "SYM", "description": "Description", "image": "ipfs://...", "attributes": [
{ "trait_type": "Background", "value": "Blue" },
{ "trait_type": "Rarity", "value": "Rare" }
],
"seller_fee_basis_points":  500
}
