On-chain
Fees
A one-time $1 creation fee, and the Manager fee: 10% of the AERO your vault claims, plus 0.01% of what is removed from your position when the bot rebalances or exits it. No management, performance or withdrawal fee on your vault, and the manager pays the gas for the bot's transactions.
Schedule
| Item | Rate | Detail |
|---|---|---|
| Vault creation | $1 | Once, in USDC, in the transaction that creates the vault. Fixed in the factory contract. Not charged on top-ups. |
| Minimum deposit | $100 | Top-ups (add funds) from $10. |
| Manager fee (emissions) | 10% | Of the AERO each claim pays, including the claim that happens automatically when the bot unstakes a position to rebalance, add to or exit it. Taken by the vault executor in the same transaction; the other 90% goes to your vault. Not taken when you withdraw. |
| Manager fee (rebalances) | 0.01% | Of each token removed from your position when the bot rebalances it, or exits it. Taken before any swap. Never charged on opening a position, adding to one, claims, swaps, or any withdrawal you make, and the bot does not charge it when a stop loss closes the position. |
| Management, performance, withdrawal | None | For your own vault: no fee on assets, no share of profits, free withdrawals. (Redeeming TRUSSV has its own fee - see below.) |
| Gas | Paid by the manager | The manager pays the gas for all of the bot’s transactions. The Vault gas line in your vault’s P&L shows the gas paid on your behalf - it is not taken from your vault. You pay gas for your own transactions: creating the vault, adding funds, withdrawing, and swaps from your wallet. |
How the fees are capped
Both Manager fees are taken by the vault executor and limited on chain. On the bot’s operations, each is capped by two ceilings: one fixed in your vault when it was created, and the executor’s own, which the TRUSS LP owner wallet sets and which can never exceed 20%. If more is asked for, the contract takes the lower ceiling.
- The 0.01% rebalance fee is the executor’s current ceiling. The owner wallet can raise it, up to your vault’s own ceiling. You can read your vault’s ceilings on Basescan: maxRemoveFeeBps (rebalances) and maxEmissionsFeeBps (emissions), in basis points (1 = 0.01%).
- If the owner wallet uses its rescue to close a position for you, the emissions fee on that close is capped only by the executor’s ceiling (10% now, up to 20%), not by your vault’s.
- The creation fee is a constant in the factory and cannot be changed.
TRUSS share vaults
A TRUSS share vault pays part of its AERO to your wallet as TRUSSV. On every claim the gross AERO is split:
| Share | Goes to |
|---|---|
| 60% | Your vault, as AERO. The bot sells or reinvests it, as in a standard vault. |
| 30% | Your wallet, as TRUSSV minted in the same transaction, with no fee. |
| 10% | The Manager fee (emissions). |
The TRUSSV is priced at the higher of NAV and the TRUSSV/WETH pool’s 5-minute average, with AERO valued at the lower of its price at the last NAV and its live price, so in this default pricing a share vault never gets more TRUSSV than NAV allows. The owner wallet can switch the pricing to NAV alone or to the pool price alone. The split is fixed in your vault when it is created, and the fee plus the TRUSSV share can never exceed 50%. The rebalance fee is the same as in a standard vault.
TRUSS VAULT mint and redeem fees
- Mint: taken from the USDC you pay in; the rest buys TRUSSV at NAV.
- Redeem: taken from the USDC value of the TRUSSV you redeem.
- Each is set by the TRUSS VAULT owner wallet and shown in the app before you sign. Both started at 25%, and the contract never allows more than 30%.
- Of each fee, half (by default) goes to the protocol’s fee wallet and the rest stays in the TRUSS VAULT as backing for every holder. When a redemption is queued, the whole fee stays as backing.
- The TRUSS VAULT owner wallet and wallets it marks fee-free pay no fee; it can also set a different fee for one wallet, never above 30%.
- Buying or selling TRUSSV in the TRUSSV/WETH pool pays that pool’s 1% fee instead.
See TRUSS VAULT for how minting and redeeming work.
Why a share of emissions
A fee on assets would charge you while your vault is out of pool. A share of emissions is only earned while your vault is in a pool and being paid, so the manager earns when you do.
Trading fees
On Aero, staked positions earn AERO emissions instead of the pool’s trading fees, which go to veAERO voters. Every TRUSS LP position is staked, so your return comes from emissions and there are no trading fees to share.
Price impact and any fee built into an aggregator’s route are part of the swap itself and show in its quote. TRUSS AGG was deployed with no fee, and the dust sweep charges none. TRUSS LP adds nothing beyond the fees above.
