The following query parameters are supported:

| Parameter      | Description                                   | Example                                      |
| -------------- | --------------------------------------------- | -------------------------------------------- |
| `fromChainId`  | The chainId of the from chain                 | `8453`                                       |
| `toAddress`    | A valid address to receive the bridge         | `0xd8da6bf26964af9d7eed9e03e53415d37aa96045` |
| `amount`       | The amount to have the input initially set to | `0.1`                                        |
| `currency`     | The currency to have preselected              | `eth` or `usdc`                              |
| `lockToChain`  | Disable selecting a toChain                   | `true`                                       |
| `lockCurrency` | Disable selecting a currency                  | `true`                                       |

To deep link to a specific `toChain`, you must replace the slug after `/bridge` with the desired chain's name, like so: `relay.link/bridge/{chainName}`. Spaces should be replaced with dashes. You can check out the list of supported chains [`here`](/resources/supported-chains).
