About this gig
I will create professional NFT metadata JSON for OpenSea, ERC721, ERC1155, and NFT collections. I specialize in building clean, accurate, and mint-ready metadata for NFT projects of any size, from small drops to large 10,000+ collections.
What I will do for you: create OpenSea-compatible JSON metadata, structure ERC721/ERC1155 collections, add names, descriptions, image/IPFS links, and attributes, build rarity systems, organize token IDs, fix JSON errors, and prepare reveal/unreveal setups. I also ensure full smart contract compatibility and deliver a ready-to-mint metadata package.
What you get: bulk NFT metadata, trait and attribute creation, rarity distribution, IPFS integration, animated NFT support, validation, and properly organized files.
I support Ethereum, Polygon, BNB Chain, Base, Arbitrum, and more. All files are clean, structured, and marketplace-ready.
I deliver fast, accurate, and fully optimized NFT metadata that works perfectly on OpenSea and other marketplaces.
