4-2. FT / NFT Design

Highly Flexible Token Design

Fungible Tokens (FT) and Non-Fungible Tokens (NFT) are essential assets for tokenomics in the ecosystem. Oasys' unique layer structure allows three types of token designs for FT and NFT. Token Design

1. vFT/vNFT, Restrictive-Use Tokens

vFT/vNFT can be minted on the Verse-Layer. The token can only be used with certain Verse-Layers. This type of FTs (e.g. in-game currency) and NFTs (e.g. IP) can not be cross-chain bridged.

2. oFT/oNFT, Highly Interoperable Tokens

oFT/oNFT can be minted on the Hub-Layer. The token is interoperable and is available on all Verse-Layers. Also, it can be sent to another network such as Ethereum by a cross-chain bridge.

3. exFT/exNFT, Minted in External Network Tokens

exFT/exNFT is a token minted on a network outside of Oasys. They are available on Oasys' Hub-Layer and Verse-Layer via cross-chain bridges.

Cross-Chain Bridge for FT / NFT

FT/NFT bridges are available: vFT and exFT for FT; and vNFT and exNFT for NFT.

Oasys NFT Bridge

For NFT transfers between Verses, Oasys provides an official bridge. The genuine bridge uses the Lock & Mint method. Tokens are locked on the chain before the bridge and minted on the chain after the bridge.

High-security Cross-chain Bridges

Many cross-chain bridges are vulnerable to being targeted by hackers because they hold large amounts of money in reserve as liquidity. Once exploited, the problem can spread throughout the entire ecosystem, posing a significant risk.

Oasys enables secure bridging between Hub-Layer and Verse-Layer and between Verse-Layers without the intervention of a centralized third-party bridge operator.
