Solvent is a platform to enable index funds for NFTs on Solana. Any NFT holder that wants liquidity out of their NFTs can deposit their NFT asset into its particular NFT collection on Solvent (bucket) for minting fungible tokens (droplets) of that particular NFT project in exchange. These fungible tokens are tradable on Serum order books just like any other tokens on Solana. This means that these droplets can be used for all DeFi applications and on-chain protocols.
