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
Inherited from
IEscrowSwapWrapper.checkPastSwaps
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>

recoverFromSwapDataAndState()
abstract recoverFromSwapDataAndState(
init,
state,
contractVersion,
lp?): Promise<D["Swap"]>;
Defined in: atomiq-sdk/src/swaps/escrow_swaps/IEscrowSwapWrapper.ts:274
Recovers a swap from smart chain on-chain data, please note that not all values for the recovered swaps might be populated, as some data is purely off-chain and can never be recovered purely from on-chain data.
Parameters
| Parameter | Type | Description |
|---|---|---|
init | { data: T["Data"]; getInitTxId: () => Promise<string>; getTxBlock: () => Promise<{ blockHeight: number; blockTime: number; }>; } | Swap escrow initialization transaction and swap data |
init.data | T["Data"] | - |
init.getInitTxId | () => Promise<string> | - |
init.getTxBlock | () => Promise<{ blockHeight: number; blockTime: number; }> | - |
state? | SwapCommitState | Current on-chain state of the swap |
contractVersion? | string | - |
lp? | Intermediary | Intermediary (LP) used as a counterparty for the swap |
Returns
Promise<D["Swap"]>

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>
