# Contracts and parameters

> Networks, contract addresses and market parameters.

Check addresses here before you sign.

## Contracts and networks

This page lists Moment's official contract addresses and supported networks.

> [!CAUTION]
>
> Only trust addresses published on this page. Treat an address from anywhere else, including chats, social posts and screenshots, as unverified. Never approve a token for a contract you cannot match here.

Networks, contract addresses and market IDs will be published here at launch.

### Finding addresses in the app

On any trade or liquidity form, click through to the technical details, **Contracts & IDs**. It shows the network, the contracts and the IDs for the market you are looking at. Check them against this page before you sign.

## Market parameters

Each Moment market is set by a small list of parameters; this page gives the example market's known values and marks the ones still to be published.

The example market is the sUSDS vault, with USDS as the underlying asset. Other markets may use other values.

### Example market

| Parameter | Value (example market) | Notes |
| - | - | - |
| Vault shares | sUSDS | ERC-4626 shares |
| Underlying asset | USDS | Balances are shown in this unit |
| Cadence | Semi-monthly | Other markets may use other cadences |
| Maturity times | 2nd and 17th of every month, 08:00 UTC | |
| Maturities open at once | 8 | A new one opens each time one matures |
| Furthest maturity | About 4 months out | |
| Taker fee | 0.5%, multiplicative on the rate | See [Fees](https://docs.momentrates.xyz/good-to-know/fees.md) |
| Performance fee | 5% of yield | See [Fees](https://docs.momentrates.xyz/good-to-know/fees.md) |

| Default slippage | 0.5% | Change it in Trade settings (the slider icon), with the deadline |
| Price source | The vault's previewRedeem | No external oracle |
| Tick step (minimum) | To be published at launch | See below |
| Spread limits (min and max) | To be published at launch | See below |

See [Reading the chart](https://docs.momentrates.xyz/start/reading-the-chart.md) for how the calendar rolls forward.

### Ticks

Rates move in ticks. The rate per second is 1.0001 raised to the power of the tick. One tick moves the rate by 0.01% of itself, so a 0.5% taker fee is about the same as moving the rate by 50 ticks.

Each market chooses its tick step when it is created.

### Spread limits

A Recursive maker's ask is their bid times a factor, and that factor must stay between the market's minimum and maximum. The rate chooser keeps your rates inside these limits. See [Recursive](https://docs.momentrates.xyz/use-the-app/recursive.md).

Each market chooses its minimum and maximum spread when it is created.
