At a glance
Bridge and account fees are collected into a separate protocol account from trading fees. The two flows are not commingled, which is what makes each one independently reconcilable from committed blocks.
Bridge fees
Deposit — the protocol charges nothing
Withdrawal — a flat protocol fee
Locked on the external chain
Credited in full
You pay the source chain’s gas, and nothing else.
The requested amount
− a flat protocol fee
Released on the destination chain
Why flat rather than a percentageWhat the protocol recovers is the cost of submitting an external-chain transaction, which does not scale with the amount moved. Withdrawals are also batched, so external costs do not grow linearly with their count.
The withdrawal fee, the activation fee, and both minimums are on-chain configuration. The reference configuration sets the withdrawal and activation fees at 1 USDC each and deposits at zero. Read the live values rather than assuming these — they are published with each release, and current values appear on Deposit.
Account activation
Transferring funds internally to an address that does not yet have an account creates one, and that first transfer carries a one-time activation fee. Subsequent transfers to the same account are free. Two exemptions are worth knowing:- Deposits never pay it. Arriving over the bridge activates an account at no charge, so funding a fresh address from outside is not penalized.
- A batch cannot double-charge. If the same new recipient appears more than once in one batch of transfers, activation is charged once.
Vault fees
The vault product is still being built; the figures below are provisional. See Vaults.
The protocol vault takes no cut. Its profits — currently the spread it earns market making, and what its taker strategy collects — go entirely to depositors, because it is the venue’s own liquidity rather than a managed product. Liquidation takeovers and a share of trading-fee revenue are part of the design but are not routed to it today; see Vaults.
A user-created vault pays its leader 10% of profit, assessed per depositor against that depositor’s own weighted-average entry NAV and charged on withdrawal or distribution — so a depositor whose shares are not above what they paid pays nothing. The leader is also required to hold at least 5% of vault value, which is the part that matters more than the fee: it means the leader’s capital moves with the depositors’ rather than only their income.
The creation fee is non-refundable and paired with a minimum initial deposit and a trading-volume requirement on the creator’s parent account. Together these price out casual vault creation, which is what keeps the vault list a set of real strategies rather than a directory of abandoned ones.
Liquidation penalty
Being liquidated costs more than the loss on the position. A penalty is applied to the liquidated position and paid into the insurance fund — the same fund that absorbs shortfalls when a liquidation closes worse than the bankruptcy price. The structure is the point. The accounts that create the risk the insurance fund exists to cover are the accounts that fund it. It is not revenue: nothing about the penalty flows to the protocol’s fee account, and it cannot be paid out as one. The penalty is a per-market parameter, set alongside that market’s other risk parameters and readable with them. See Markets.What you are never charged
Gas on trading. Submitting, amending, and cancelling orders are native protocol transactions with no gas requirement and no fee market. See Trading fees. A fee for having a position open. Holding costs funding, which is a transfer between longs and shorts, not a protocol charge. Depending on which side you hold, it is income. A fee for cancelling. Cancellation is free and unlimited. A venue that charges for cancellation gets stale quotes during exactly the volatility where fresh ones matter. An inactivity or maintenance fee. An account that does nothing costs nothing.Where to go next
