Glossary

Claim window

The span in which a pending withdrawal can be claimed: the request window of that request's unlock epoch, currently the first 2 days of it. Claim inside it or the request expires. See Withdrawing.

Collateral

USDC deposited by a trader to back a leveraged position. This is the capital at risk.

Cool-off

The waiting period between submitting a withdrawal request and that request becoming claimable. Counted in epochs and set by vault collateralization at the moment you request. See Withdrawing.

Cooldown

The closing part of each epoch, during which the vault settles the epoch by sampling open PnL and no withdrawal request or claim goes through. Currently the last day of each 3-day epoch, drawn as a labelled band on the epoch timeline in the app, and shown as the status In Cooldown on a pending withdrawal in its unlock epoch. It describes the vault's state, not your request's. Distinct from a withdrawal's cool-off, which is the 1–3 epoch wait attached to a single request. See Withdrawing.

Dominance

An asset's share of total cryptocurrency market capitalization, measured against the top 200 assets by market cap. Expressed as a percentage.

$dfUSDC

The ERC-4626 vault share token. Represents a proportional claim on the vault's USDC holdings. Price fluctuates based on trader PnL and fee accrual.

Epoch

The vault's settlement period. Unrealized PnL is committed to the $dfUSDC share price at each epoch boundary, and withdrawal cool-offs and claim windows are counted in epochs. Epoch length is a configurable protocol parameter, currently 3 days, and boundaries are not aligned to a calendar schedule. Each epoch splits into a request window, in which withdrawal requests and claims are accepted, and a Cooldown, in which they are not. dfPOINTS uses a separate weekly epoch, unrelated to the vault's — see Points.

Funding Rate

A continuous per-block payment between longs and shorts. The side with more open interest pays the side with less. Incentivizes balanced OI and anchors perpetual prices to the oracle index.

Isolated Margin

Each position has its own dedicated collateral. Losses on one position do not affect others. DomFi uses isolated margin exclusively.

Leverage

The multiplier applied to collateral to determine position size. 50x leverage on $100 collateral = $5,000 position. Higher leverage amplifies both gains and losses.

Liquidation

Forced closure of a position when its value drops to or below the liquidation margin. The trader receives nothing — all remaining collateral goes to the vault.

Liquidation Margin

A reserve calculated from collateral and leverage: collateral x (25% x leverage / maxLeverage). This is the threshold below which liquidation triggers.

Maker / Taker

Fee classification based on OI impact. Makers reduce OI imbalance and pay the lower rate; takers increase it and pay the higher rate. Maker pricing also requires leverage of 20x or below. Rates vary by pair. See Fees.

Open Interest (OI)

Total notional value of all outstanding positions. Tracked per pair, per direction (long/short). Caps vary by pair. See Trading Overview.

Oracle

The off-chain system that computes dominance values from exchange price feeds and publishes them on-chain via ECDSA-signed messages.

Position Size

Collateral multiplied by leverage. A $100 collateral position at 50x has a $5,000 position size. Fees are charged on position size, not collateral alone.

Request window

The opening part of each epoch, during which withdrawal requests and claims are accepted. Currently the first 2 days of each 3-day epoch. Deposits are not restricted to it. See Withdrawing.

Slippage

The maximum acceptable difference between expected and actual execution price. Set when submitting a market order.

Take-Profit (TP) / Stop-Loss (SL)

Automated price triggers. TP closes your position when profit reaches a target. SL closes it to cap losses. Both execute the full position. TP is capped at 900% of collateral.

Unlock epoch

The epoch in which a withdrawal request becomes claimable, and the only epoch in which it can be claimed. A request cannot be claimed before it, and it expires at its end. Claiming happens during that epoch's request window, not its Cooldown. See Withdrawing.

Vault

The ERC-4626 USDC pool that acts as collective counterparty to all trades. LPs deposit USDC, receive $dfUSDC shares, and earn trading fees.
