Query Parameters
The Pegasys front-end supports URL query parameters to allow for custom linking to the Pegasys frontend. Users and developers can use these query parameters to link to the Pegasys frontend with custom prefilled settings.
Each Page has specific available URL parameters that can be set. Global parameters can be used on all pages.
A parameter used on an incorrect page will have no effect on frontend settings. Parameters not set with a URL parameter will be set to standard frontend defaults.
Global
| Parameter | Type | Description |
|---|---|---|
| theme | String | Sets them to dark or light mode. |
Theme Options
Theme can be set as light or dark.
Example Usage
https://app.pegasys.fi/#/swap?theme=dark
Swap Page
| Parameter | Type | Description |
|---|---|---|
| inputCurrency | address | Input currency that will be swapped for output currency. |
| outputCurrency | address or ETH | Output currency that input currency will be swapped for. |
| exactAmount | number | The custom token amount to buy or sell. |
| exactField | string | The field to set custom token amount for. Must be input or output. |
Defaults
ETH defaults as the input currency. When a different token is selected for either input or output ETH will default as the opposite selected currency.
Constraints
Addresses must be valid ERC20 addresses. Slippage and amount values must be valid numbers accepted by the frontend (or error will prevent from swapping). Slippage can 0, or within the range 10->9999 bips (which converts to 0%, 0.01%->99%)
When selecting ETH as the output currency a user must also choose an inputCurrency that is not ETH (to prevent ETH being populated in both fields)
Setting Amounts
Two parameters, exactField and exactAmount can be used to set specific token amounts to be sold or bought. Both fields must be set in the URL or there will be no effect on the settings.
