The Yearn numbers that are available at the moment can be found in the Yearn Treasury. This is where all of the funds from the Yearn ecosystem are held. With the introduction of veYFI, a portion of these funds will now be allocated to stakers as rewards. This will help to increase the liquidity of the Yearn ecosystem, as well as provide rewards for those who are actively staking their tokens. As the Yearn ecosystem continues to grow and evolve, the numbers of Yearn tokens available will continue to change, so it is important to stay up to date with the latest numbers.
