Litra is creating deep NFT liquidity using advanced bonding curves and veToken model to provide NFT Liquidity as a Service and empower NFT pricing. To solve the low liquidity issue of the NFT market, the Litra protocol will turn an NFT into a standard asset by locking the NFT in the protocol and minting the corresponding wrapped NFT (ERC-20). This has the features of auto-concentrated liquidity and customised bonding curves, which not only reduce impermanent loss for liquidity providers, but also benefit traders with exceptionally low slippage.
