How the gDAI vault works
The gDAI Vault is an ERC-4626 compliant DAI vault where gDAI shares represent the underlying DAI asset. As the counterparty to all trades, the vault pays out winnings to traders and receives losses in exchange for a portion of trading fees that are split among gDAI shares to incentivize stakers to remain in the vault. Collateralization depends on trader PnL, and when overall PnL is negative, the vault creates a buffer to protect stakers' funds and the protocol from future abnormalities. The vault follows an epoch system for capturing snapshots of open PnL to better approximate the real collateralization ratio and minimize risks for the protocol and stakers.
How gDAI accrues value
gDAI is a token that represents ownership of the underlying DAI. It follows an exchange rate model that takes into account two variables: accumulated fees and trader PnL (both open and closed). The value of gDAI to DAI changes in real-time based on these variables. The accumulated fees represent how many fees a single gDAI has accrued over time, while trader PnL is a snapshotted value of the profit or loss from closed trades and a snapshot of open trades from the end of the previous epoch. The value of trader PnL can move in either direction, so the value of gDAI can fluctuate based on both accumulated fees and trader PnL.
How the epoch system works
The epoch system is a decentralized way of providing the gDAI vault with open PnL data to better understand its collateralization ratio. On-chain calculation of open PnL is too computationally expensive to do in real-time, so the system has two states: the withdraw window and the open PnL window. During the withdraw window, stakers may make withdraw-related actions, but open PnL values are not being received. In the open PnL window, the protocol requests open PnL snapshots from oracles, taking the median value from a network of oracles, and then averages it across the request periods. The stakers' DAI cannot be withdrawn immediately for the security of the vault, and depending on the collateralization ratio, a staker may need to wait 1 (ratio >120%), 2 (>110%), or 3 epochs after making a request before being able to withdraw.
