switchChainAndRouteMessage
function switchChainAndRouteMessage(uint256 forkId) external
To be called after the sending of the cross-chain message (ccipSend). Goes
through the list of past logs and looks for the CCIPSendRequested event.
Switches to a destination network fork. Routes the sent cross-chain message on
the destination network.
Parameters
| Name | Type | Description |
|---|---|---|
| forkId | uint256 | The ID of the destination network fork. This is the returned value of createFork() or createSelectFork() |
getNetworkDetails
function getNetworkDetails(uint256 chainId) external view returns (struct Register.NetworkDetails)
Returns the default values for currently CCIP supported networks. If network is
not present or some of the values are changed, user can manually add new network
details using the setNetworkDetails function.
Parameters
| Name | Type | Description |
|---|---|---|
| chainId | uint256 | The blockchain network chain ID. For example 11155111 for Ethereum Sepolia. Not CCIP chain selector. |
Return Values
| Name | Type | Description |
|---|---|---|
| [0] | struct Register.NetworkDetails | networkDetails - The tuple containing: chainSelector - The unique CCIP Chain Selector. routerAddress - The address of the CCIP Router contract. linkAddress - The address of the LINK token. wrappedNativeAddress - The address of the wrapped native token that can be used for CCIP fees. ccipBnMAddress - The address of the CCIP BnM token. ccipLnMAddress - The address of the CCIP LnM token. |
setNetworkDetails
function setNetworkDetails(uint256 chainId, struct Register.NetworkDetails networkDetails) external
If network details are not present or some of the values are changed, user can
manually add new network details using the setNetworkDetails function.
Parameters
| Name | Type | Description |
|---|---|---|
| chainId | uint256 | The blockchain network chain ID. For example 11155111 for Ethereum Sepolia. Not CCIP chain selector. |
| networkDetails | struct Register.NetworkDetails | The tuple containing: chainSelector - The unique CCIP Chain Selector. routerAddress - The address of the CCIP Router contract. linkAddress - The address of the LINK token. wrappedNativeAddress - The address of the wrapped native token that can be used for CCIP fees. ccipBnMAddress - The address of the CCIP BnM token. ccipLnMAddress - The address of the CCIP LnM token. |
requestLinkFromFaucet
function requestLinkFromFaucet(address to, uint256 amount) external returns (bool success)
Requests LINK tokens from the faucet. The provided amount of tokens are transferred to provided destination address.
Parameters
| Name | Type | Description |
|---|---|---|
| to | address | The address to which LINK tokens are to be sent. |
| amount | uint256 | The amount of LINK tokens to send. |
Return Values
| Name | Type | Description |
|---|---|---|
| success | bool | Returns true if the transfer of tokens was successful, otherwise false. |
