Flexibility of Fungible Token(FT) & Non Fungible Token(NFT)

For basic concepts, you can read the Whitepaper.

oFT​

oFT means Oasys Fungible Token. Deploying contracts on the Hub Layer(L1) is highly restricted. The primary purpose is to use the Hub Layer as a data availability layer. It would be best to ask the Oasys Foundation to deploy new contracts, but you can deploy an ERC-20 with the Factory contract. Using L1StandardERC20Factory.sol, You can make your tokens with Factory Contract.

vFT​

vFT means Verse Fungible Token. You can freely deploy ERC-20 contracts on your Verse. However, if you still need to get your Verse, you may ask verse operators to request permission to deploy your contract. A vFT is minted on the Verse. At the same time, when bridging from the Hub Layer to the Verse Layer, it remembers the dataset of a token. The bridge contract rejects transactions if a dataset is unavailable and a bridge request is sent from the Verse Layer. vFTs can not be cross-chain bridged.

exFT​

exFT means External Fungible Token. An exFT is the same as an oFT, mainly created by L1StandardERC20Factory.sol or Bridges. So you can bring your ERC-20 contract from an external chain onto Oasys.

oNFT​

oNFT means Oasys Non Fungible Token. Deploying contracts on Hub Layer(L1) is highly restricted. The primary purpose is to use Hub Layer as a data availability layer. It would be best to ask Oasys Foundation to bring a new contract deployment, but you can deploy ERC-721 with a Factory contract. Using L1StandardERC721Factory.sol, You can make your tokens with Factory Contract.

vNFT​

vNFT means Verse Non Fungible Token. You can freely deploy ERC-721 contracts on your Verse.For deploying vNFT, you may ask verse operators to request permission to deploy your contract. A vNFT is minted on the Verse. At the same time, when bridging from the Hub Layer to the Verse Layer, it remembers the dataset of a token. The bridge contract rejects transactions if a dataset is unavailable and a bridge request is sent from the Verse Layer. vNFTs can not be cross-chain bridged.

exNFT​

exNFT means External Non Fungible Token. An exNFT is the same as an oNFT, mainly created by L1StandardERC721Factory.sol or Bridges. So you can bring your ERC-20 contract from the external chain onto Oasys.
