Fees and limits
Every fee you pay and every limit that applies, and where each one is enforced.
On this page
This page lists every fee you can pay while using Floatless and every limit that applies to your money, with where each one is enforced.
Fees at a glance
| Fee | When you pay it | How much | Where it's enforced |
|---|---|---|---|
| Monad network fee | Each payment, savings deposit or withdrawal, and spending-rules registration | Set by Monad, paid in MON | Monad charges it. For payments, the app also holds it to a ceiling you approve. |
| Floatless Savings performance fee | Only on interest your savings earn on mainnet | 10% of the interest | The savings vault contract |
| Emergency exit fee | Only if you choose Withdraw straight from Morpho | 0.01% of the amount you take out that way | The savings vault contract |
| Savings deposit or withdrawal fee | Never | None | |
| Floatless fee for sending or receiving | Never | None |
Floatless itself doesn't charge you to send money, receive money, set spending rules or create goals. Where a transaction is involved, you pay only Monad's network fee. The app doesn't swap one currency for another, so there are no swap fees, and cards aren't available yet, so there are no card fees.
Network fees in MON
Every transaction your wallet sends on Monad costs a network fee, paid in MON, Monad's own currency. Floatless doesn't pay these fees for you, so keep some MON in your wallet. Add money explains how to get it. On testnet you pay in testnet MON.
| What you do | Transactions | Network fee |
|---|---|---|
| Send money | 1 | Yes, with a maximum you see before you confirm |
| Add to savings | 1, or 2 when an approval is needed first | Yes |
| Withdraw from savings | 1 | Yes |
| Register spending rules | 1 | Yes |
| Receive money, create or edit goals, or run a payment check | None | No |
The approval before a savings deposit lets the vault take exactly the amount you're depositing and nothing more.
A declined payment costs nothing, because nothing is sent. A transaction that's sent and then fails onchain can still cost a fee, and the app warns you when that happens.
The fee ceiling on payments
On the review screen, Network fee shows the maximum in MON as "Up to X MON", with a dollar estimate when Floatless has a MON price. You pay it in addition to the amount you send. That maximum holds all the way to Monad.
- The Floatless API estimates the gas your transfer needs, adds a 20% margin, and multiplies by the current gas price. That's the maximum you see.
- When you tap Send $X, the app asks for a fresh payment check. If the new maximum is higher, it stops with "Network fees changed. Return to review and approve the new fee ceiling."
- The app builds the transaction with exactly that gas limit and gas price.
- After signing, the app checks that the signed transaction still has that gas limit and gas price before it broadcasts it.
A transaction can't spend more than its gas limit times its gas price, so you can't pay more than the maximum you approved.
Savings deposits, withdrawals and rule registrations also add a 20% margin to the gas estimate and use the current gas price, but the app doesn't show a maximum for them before you approve.
Floatless Savings fees
Floatless Savings runs on Monad mainnet. On testnet the Save tab only shows a preview, nothing is deposited, and there's nothing to pay.
- Performance fee: 10% of the interest your savings earn. The vault takes it by creating new vault shares for the Floatless fee address as interest builds up. Your deposits themselves aren't charged.
- The rate on the Save tab, shown as a percentage "a year", already has the fee taken out, and a note on the card says "Rate after fees." It's Morpho's reported rate for the underlying vault without reward tokens, minus the 10% fee.
- There's no deposit fee, no withdrawal fee and no management fee. The vault's management fee is set to 0.
- Emergency exit fee: 0.01%. If the usual withdrawal path is paused, the app can offer Withdraw straight from Morpho, which pulls your money straight out of Morpho. The app shows the exact fee in AUSD first, and nothing happens unless you tap it. The fee comes out of your own savings and stays in the vault, so other savers don't pay for your exit.
Changing any of these fees takes a proposal from the vault's curator and a 3-day public wait, so you'd see it coming and could withdraw first. Keys and security explains who holds which key, and Floatless Savings covers how saving works.
Limits at a glance
| Limit | Value | Where it's enforced |
|---|---|---|
| Each payment up to | You choose it, more than 0 | The payment check |
| Each day up to | You choose it, at least your per-payment limit, counted from midnight UTC | The payment check |
| Always keep at least | You choose it, 0 or more, for the currency you're paying with | The payment check |
| Currencies you can send | At least one | The payment check |
| Rules last for | 30, 90 or 180 days | The payment check and the rules registry |
| Goal Keep protected (optional) | From 0 up to the goal's target | Checked when you save the goal, then applied by the payment check |
| Payment amount | Up to your balance in that currency, typed in dollars with up to 2 decimal places | The app and the payment check |
| Payment check | Good for up to one minute | The app |
| Network fee on a payment | The maximum shown at review | The app, then the signed transaction |
| Savings deposits | 100,000 AUSD in total, across all savers | The savings vault contract |
| Savings withdrawals | What Morpho can pay out right now | The savings vault and Morpho |
The payment check is run by the Floatless API, at POST /v1/send/quote, when you review a payment and again right before you sign. It covers payments made with Send in Floatless and doesn't stop transfers made outside Floatless. Spending rules explains why.
Spending rule limits
You set most of the limits above in your spending rules, and you choose the numbers.
- Each day up to adds up every payment Floatless recorded since midnight UTC, in all currencies and from all your devices, plus the one you're making.
- Always keep at least is compared with your balance in the currency you're paying with. Your goal floors work the same way, and Floatless applies whichever floor is larger.
- When your rules expire, payments are declined until you register new ones.
Savings limits
- Floatless Savings accepts up to 100,000 AUSD in total, across all savers. A deposit that would go over the cap is refused by the vault, and the app says "Floatless Savings is full right now. Try a smaller amount, or try again later." Raising the cap takes a curator proposal and the 3-day wait. The owner can lower it right away, and a lower cap limits new deposits without blocking withdrawals.
- Only AUSD goes into Floatless Savings, and you can deposit up to the AUSD in your wallet.
- You can withdraw what Morpho can pay out right now. When it's less than your savings, the Save tab says "Only X AUSD can be withdrawn right now", and the Withdraw sheet shows the amount as "ready to withdraw". When Morpho's markets are heavily borrowed, that can be less than your full savings until borrowers repay.
