NFT Metadata Upload & Review

NFT Metadata Upload & Review is a paid DEUCE service for artists who need help preparing a JSON metadata file or OpenSea Studio upload package for their artwork, edition, or collection.

OpenSea supports ERC-721 and ERC-1155 style metadata. For Studio drops, OpenSea describes uploading media files and a metadata CSV. DEUCE can help artists organize the required information, review the file, and prepare a clean upload package.

Fees

  • Single metadata file review: $25 per item.
  • Metadata file creation: $50 per item when DEUCE builds the JSON from your submitted information.
  • Small collection package: starts at $111 for up to 10 items.
  • Full guided collection setup: $250 for collection planning, metadata structure, upload prep, and minting direction.
  • IPFS/Arweave upload, minting, gas, QR/NFC tags, certificates, and technical support: quoted separately.

What to Upload or Send

  • Artwork title
  • Artist name
  • Description
  • Image, video, audio, 3D file, or media link
  • External URL, such as the OpenSea item page, artist page, or Proof-of-Print information page
  • Edition number and edition size
  • Traits or attributes, such as medium, year, material, chain, collection, or location
  • Collection name
  • Wallet address and preferred marketplace or chain
