The SFI token is capped at 100,000 and is generated every 2 weeks during the wind down of an epoch. Tokens are earned by LPs proportional to how many dollars per second (dsec) they provided to the system for the duration of an epoch. SFI token subsidy is halved every epoch until epoch 8. From that point on, the system steadily releases 200 SFI tokens per epoch, until reaching the 100,000 cap. There are no fees on Saffron in version 1. Later versions will introduce Saffron platform fees, and at that time, staking SFI tokens will earn SFI holders a proportion of fees incurred by users. When SFI token generation ends fees will continue to provide incentives to liquidity providers. SFI tokens must be staked for LPs to join the enhanced return A tranche.
