DFI.Money, also known as YFII, is a decentralized finance (DeFi) platform that originated as a fork of the well-known DeFi aggregator, yearn.finance (YFI). Launched in July 2020, DFI.Money seeks to optimize potential benefits for DeFi participants by adhering to changes proposed in an upgrade plan known as YIP-8. The platform's native token is YFII, a fixed-supply token that liquidity providers receive based on their interaction with the network. DFI.Money also offers a unique feature known as the Vault, which it describes as its "killer product."

DFI.Money operates by allowing users to join one or both of its two liquidity pools, which feature Curve (CRV) or Balancer (BAL). Users receive YFII tokens as a reward for providing liquidity. The platform also introduced the Vault, a feature that aims to provide users with potential returns of any token automatically according to user-submitted strategies, without the users themselves manually setting up transactions. DFI.Money's protocol is community-owned and does not offer commercial incentives such as developer rewards by default.

DFI.Money serves as a platform for DeFi participants who aim to maximize their potential benefits by providing liquidity. It caters to users of its predecessor, yearn.finance, who voted in favor of the YIP-8 upgrade plan, as well as new DeFi participants. The platform's Vault feature seeks to provide users with potential returns on any token automatically, based on user-submitted strategies. This eliminates the need for users to manually set up transactions, making it a potentially useful tool for those seeking to optimize their DeFi participation.

DFI.Money originated as a hard fork of yearn.finance, a DeFi returns aggregator created by Andre Cronje. In July 2020, a proposal to protect liquidity provision from whales earned 80% support among protocol participants but was not adopted due to not meeting yearn.finance's requisite 33% quorum requirement. As a result, a group of users opted to hard fork the protocol to create DFI.Money, with its own token, YFII. The hard fork implemented the proposal, known as YIP-8, which adjusts YFII distribution each week, following a pattern popularized by Bitcoin (BTC).
