NFT Token Types Supported on OpenMark

OpenMark supports ERC721, ERC1155, and DN404 token standards. Below is a comparison of ERC721 and ERC1155, their benefits, and when to use them.

ERC721 vs. ERC1155: Key Differences

Feature	ERC721 (Single NFTs)	ERC1155 (Multi-Token NFTs)
Uniqueness	Each token is one-of-a-kind	Can have multiple copies of the same token
Ownership	One owner per NFT	Multiple owners per token (shared supply)
Gas Fees	Higher gas costs (each transaction handles a single NFT)	Lower gas fees (batch transactions for multiple NFTs)
Use Cases	Profile pictures (PFPs), collectibles, 1/1 art	Game items, membership passes, fractionalized assets
Batch Transfers	❌ Not supported (one NFT per transfer)	✅ Supported (transfer multiple NFTs in one transaction)

When to Use Each?

Use ERC721 if:

• You want unique, one-of-a-kind NFTs.

• Your collection consists of individual ownership items (e.g., PFPs, digital art, exclusive collectibles).

• Scarcity is important—each token has a unique value.

Use ERC1155 if:

• Your project includes game assets, event tickets, or membership passes where multiple users can own the same item.

• You want efficient gas usage with batch transfers.

• You need semi-fungible tokens (some items are identical but still tradable).

Quick Note on DN404

OpenMark also supports DN404, a hybrid NFT standard combining ERC20 and ERC721 benefits. This allows NFTs to be more liquid, tradable like tokens while still being unique assets.
