Cours de DFI.Money

DFI.Money ($YFII) is a Ethereum and BNB Chain based DeFi-farming aggregator that automatically puts your crypto assets to earn high yield profits.

YFII is a fork of YFI project from YIP-8 upgrade in July 2020.

What is Yearn and YFI?

Yearn Finance is a yield aggregator for DeFi lending platforms that rebalances for highest yield during contract interaction which supports Compound, dYdX, Aave and DDEX protocols. When users put their money into the platform, it automatically transfers the assets into the protocol that has the highest yield, and returns a proof of stake called yToken. Users can send back yTokens at any time to withdraw their deposits along with the interest.

Moreover, Yearn and Curve together created y.curve.fi, a pool for stable coin exchange. Besides enjoying the interest on lending, yToken holders can put their tokens into the exchange pool of y.curve.fi to become a market maker, generating extra incomes. Such a combo now ranks first among all DeFi platforms by APR.

YFI is the token used for governing Yearn protocol. Its initiator Andre Cronje admitted that he had no interest in participating in the governance and wished the community to be autonomously organized. Until July 26th, YFI has been issued to yield farmers who provide liquidity to the pools (Info from debank.com).

YIP-8 and forking of YFI

As mentioned above, the mining/farming of YFI has stopped on July 26. In order to prevent a sharp drop in liquidity of the pools, the community proposed YIP-8, suggesting a weekly halving model for yield farming. Though more than 80% of the votes are FOR the proposal, it has been declined because of the unmet 33% quorum requirement. To protect Andre's genius design from being spoilt by whales, we forked YFI, naming it YFII. The issuance of YFII imitates the halving model of Bitcoin so that the tokens will be fairly distributed to the community.

YFII Token Design

The total supply of YFII is 40,000. Each of the two pools will be emitting 20,000 tokens to yield farmers, starting at 10,000 in the first week halving every 7 days. The number of tokens farmed is in proportion to the liquidity farmers provide to the pools. YFII will be completely distributed in the following 10 weeks.

Burning of admin key
People may be worrying that if the developers would issue infinite number of YFII tokens to steal their money. The answer is: impossible. The minting keys have already been burnt by transferring the admin role to the blackhole address (0x00) so that no one has this privilege to mint new tokens. You can examine the burning txns below which are also documented at a specific page.
