How OpenMF works
Plain answers about investing, leaving a fund, fees and loans.
The short version
OpenMF lets you invest in funds run by professional managers. You hold fund shares in your own OpenMF account. The price of a share follows the value of what the fund holds. You can withdraw, and you can always leave a fund without the manager by using a force redeem.
Getting started
- Sign in with a passkey, Google or an email link. The first time, OpenMF creates your account.
- Add money by card or bank, or send USDC from another wallet.
- Pick a fund and invest.
Investing and withdrawing
Public funds accept money straight away. You get shares at the current price, and a withdrawal pays out to you in the same step.
Private funds need the manager to accept each order. An order lasts 24 hours. Your money or shares stay in your account until the order goes through, and you can cancel any time before. A manager can add a short public reason when they decline an order; anyone can read it.
Withdrawals pay out to you in the same transaction that removes your shares. Nothing is held back and there is nothing to claim later.
Force redeem
You can leave a fund without the manager. Start a force redeem and your shares are set aside. After a wait set by the OpenMF protocol, you finish it to receive your share of each thing the fund holds. The screen shows exactly when you can finish, and you can cancel at any point before you do.
If part of a fund’s holdings can’t be delivered when you finish, that part stays with the fund’s other investors for good. The app shows this before you confirm and asks you to acknowledge it.
Fees
| Fee | When it’s charged |
|---|---|
| Entry | Taken from the money you invest. |
| Exit | Taken from the shares you withdraw. |
| Management | A yearly rate, built into the share price. |
| Performance | A cut of gains above the fund’s previous high. |
Each fund’s manager sets its own rates, and every fund page lists them before you invest. Network costs are shown when they apply.
Loans and leverage
Not available yet
Once it opens, some funds will be accepted by OpenMF as collateral, fund by fund (the lending market runs on Euler). A share-backed loan gives you USDC while your shares stay invested and are returned when you repay the loan and its interest. Leverage is a loan whose USDC is invested straight back into the same fund.
If what you owe grows too close to what your shares are worth, OpenMF sells some of your shares to repay the loan. This is called liquidation. It carries a penalty and can’t be undone.
Risk disclosure
Investing involves risk, including losing money. Past returns don’t promise future results. A fund’s manager chooses its investments and can lose money. Values shown can be out of date, and the app says so when they are. Nothing here is financial advice.
