| Parameter | Type |
|---|---|
chainIdentifier | T["ChainId"] |
unifiedStorage | UnifiedSwapStorage<T> |
unifiedChainEvents | UnifiedSwapEventListener<T> |
chain | T["ChainInterface"] |
prices | ISwapPrice |

Properties
chainIdentifier
readonly chainIdentifier: T["ChainId"];
Defined in: atomiq-sdk/src/swaps/ISwapWrapper.ts:164
Chain identifier string of this wrapper
events
readonly events: EventEmitter<{
swapState: [D["Swap"]];
}>;
Defined in: atomiq-sdk/src/swaps/ISwapWrapper.ts:168
Event emitter emitting "swapState" event when swap's state changes
TYPE
abstract readonly TYPE: SwapType;
Defined in: atomiq-sdk/src/swaps/ISwapWrapper.ts:74
Swap type
Methods
checkPastSwaps()
checkPastSwaps(pastSwaps?, noSave?): Promise<{
changedSwaps: D["Swap"][];
removeSwaps: D["Swap"][];
}>;
Defined in: atomiq-sdk/src/swaps/ISwapWrapper.ts:424
Runs checks on all the known pending swaps, syncing their state from on-chain data
Parameters
| Parameter | Type | Description |
|---|---|---|
pastSwaps? | D["Swap"][] | Optional array of past swaps to check, otherwise all relevant swaps will be fetched from the persistent storage |
noSave? | boolean | Whether to skip saving the swap changes in the persistent storage |
Returns
Promise<{
changedSwaps: D["Swap"][];
removeSwaps: D["Swap"][];
}>
Remarks
Doesn't work properly if you pass non-persisted swaps
init()
init(noTimers, noCheckPastSwaps): Promise<void>;
Defined in: atomiq-sdk/src/swaps/ISwapWrapper.ts:360
Initializes the swap wrapper, needs to be called before any other action can be taken
Parameters
| Parameter | Type | Default value | Description |
|---|---|---|---|
noTimers | boolean | false | Whether to skip scheduling a tick timer for the swaps, if the tick timer is not initiated the swap states depending on e.g. expiry can be out of sync with the actual expiration of the swap |
noCheckPastSwaps | boolean | false | Whether to skip checking past swaps on initialization (by default all pending swaps are re-checked on init, and their state is synchronized from the on-chain data) |
Returns
Promise<void>
stop()
stop(): Promise<void>;
Defined in: atomiq-sdk/src/swaps/ISwapWrapper.ts:401
Un-subscribes from event listeners on the smart chain, terminates the tick interval and stops this wrapper
Returns
Promise<void>
tick()
tick(swaps?, abortSignal?): Promise<void>;
Defined in: atomiq-sdk/src/swaps/ISwapWrapper.ts:459
Invokes ISwap._tick on all the known swaps
Parameters
| Parameter | Type | Description |
|---|---|---|
swaps? | D["Swap"][] | Optional array of swaps to invoke _tick() on, otherwise all relevant swaps will be fetched from the persistent storage |
abortSignal? | AbortSignal | Abort signal |
Returns
Promise<void>
