# Limits and fees

> Every minimum, limit, wait and fee in one place.

**A limit you know about is a limit you can plan around.** This page lists everything that can limit or slow down minting and redeeming. Most of it is written into the contract, so it applies to every Mint User the same way.

Holding and sending USDh has no minimum and no fee. You only pay Ethereum's network fee.

## Minting and redeeming

| What | Limit or timing | Enforced by |
| - | - | - |
| Who can mint or redeem | Mint Users, from one approved wallet, and approved routes | Contract |
| Minimum mint | USD 100,000 or the equivalent. Can be changed by agreement | Agreement |
| Mint with USDC | Instant, one for one, in one transaction | Contract |
| Mint with a wire | Usually 3 to 5 business days, once the funds clear | Operations |
| Wire-minted USDh per day | A fixed total in each 24-hour window, shared by all Mint Users. The window opens with the first wire mint and resets 24 hours later | Contract |
| Redemption limit | By default, **half of your USDh balance** (measured when you last minted) in each 7-day window. The window opens with your first redemption and resets 7 days later. A higher limit, or none, can be agreed | Contract |
| Possible delay | Up to 5 business days if reserve assets are still settling or markets are disrupted, with notice and a new date | Agreement |
| Accepted | USDC and US dollar wires. USDT, AUSD, USDS and USDe are planned | Contract and operations |
| Fees | None today. Your own bank's fees apply to wires. Any new fee needs 30 days' notice | Agreement |

## Changes to the system

| What | Timing | Enforced by |
| - | - | - |
| Any admin change: new code, accepted stablecoins, the treasury address, redemption settings, the daily wire limit | Scheduled publicly on the blockchain **at least 48 hours** before it can take effect | Timelock contract |
| Emergency actions: pause everything, freeze one address, switch off a stablecoin that has lost its peg | Immediate | Pauser wallet |

Emergency actions can only **stop** things. They cannot create USDh, change prices or take anyone's balance. See [Security](https://docs.hamilton.xyz/trust-and-transparency/security-and-audits.md).

## Worked example: a redemption window

**1. Mint**

A business mints 1,000,000 USDh. Its wallet now holds 1,000,000 USDh, so its limit is set to **500,000 USDh** per window.

**2. Monday**

It redeems 300,000 USDh. A 7-day window opens.

**3. Wednesday**

It asks to redeem another 300,000 USDh. That would take it to 600,000 in this window, over the limit, so the contract refuses. It can still redeem 200,000.

**4. The next Monday**

The window closes. A new one opens with its next redemption.

*Where this page differs from the Mint user agreement or the USDh terms, those documents win.*
