Jungle Finance is a DeFi primitive protocol on the Solana blockchain that lets users create, buy, sell, and redeem their staking or farm rewards right away. Users can deposit SPL Tokens into Jungle auto-compounding vaults and receive two distinct tokens: one token tracks ownership of the staking or farm rewards produced over a defined time window, while the other token reflects ownership of the underlying base asset after subtracting those rewards. 

The reward-side tokens (iTOKENS) can be purchased or sold immediately-either to bet on whether yields will move up or down, or to improve capital efficiency by enabling instant access to upcoming yield. In practice, iTOKENS function as yield futures for supported assets. Base asset tokens (jTOKENS) can be used to speculate on price, serve as collateral for loans, or create synthetic assets, along with many other possible applications that the Solana DeFi community is invited to help develop and compete with. 

JFI tokens act as the governance token for the Jungle DeFi platform. After governance is introduced as a protocol feature, token holders will be able to submit proposals and vote on items like which vaults join the platform, vault duration, token emission rate (linked to vaults), the fee schedule, and how the treasury is managed. At launch, proposals and voting will initially be limited to adding new vaults. Any additional proposals must be published publicly with full code and a longer proposal period to allow community review prior to being implemented.
