The total supply of Uniswap’s governance token, UNI, is 1 billion units. These will become available over the course of four years, after which Uniswap will introduce a “perpetual inflation rate” of 2% to maintain network participation.
Token distribution currently consists of the following: 60% to Uniswap community members, i.e. users, 21.51% to team members, 17.8% to investors and 0.69% to advisors. The latter three distributions will occur according to a four-year vesting schedule.
Out of the majority set to go to users, 15% can be claimed by those who used Uniswap prior to Sep. 1, 2020. These even include users who submitted transactions which were never successful — they are eligible for 400 UNI.
The UNI token serves the purpose of enabling shared community ownership in the growth and development of the decentralized protocol. This allows UNI holders to participate in the governance of the Uniswap protocol and wider ecosystem, in a neutral and trustless manner. The success and adoption of Uniswap products will positively impact Uniswap price, hence incentivizing token holders to contribute to the self-sustaining development of the ecosystem.
Four years after the UNI token launch, in September 2024, a perpetual inflation rate of 2% annually will take effect. This is to ensure that participation in the Uniswap ecosystem continues, by disincentivizing passive holders.
