Inherited from

IEscrowSwapWrapper.constructor

Properties

chainIdentifier

readonly chainIdentifier: T["ChainId"];

Defined in: atomiq-sdk/src/swaps/ISwapWrapper.ts:142

Chain identifier string of this wrapper

Inherited from

IEscrowSwapWrapper.chainIdentifier


events

readonly events: EventEmitter<{
swapState: [D["Swap"]];
}>;

Defined in: atomiq-sdk/src/swaps/ISwapWrapper.ts:146

Event emitter emitting "swapState" event when swap's state changes

Inherited from

IEscrowSwapWrapper.events


TYPE

abstract readonly TYPE: SwapType;

Defined in: atomiq-sdk/src/swaps/escrow_swaps/IEscrowSwapWrapper.ts:32

Swap type

Inherited from

IEscrowSwapWrapper.TYPE

Methods

checkPastSwaps()

checkPastSwaps(pastSwaps?, noSave?): Promise<{
changedSwaps: D["Swap"][];
removeSwaps: D["Swap"][];
}>;

Defined in: atomiq-sdk/src/swaps/ISwapWrapper.ts:369

Runs checks on all the known pending swaps, syncing their state from on-chain data

Parameters

ParameterTypeDescription
pastSwaps?D["Swap"][]Optional array of past swaps to check, otherwise all relevant swaps will be fetched from the persistent storage
noSave?booleanWhether to skip saving the swap changes in the persistent storage

Returns

Promise<{ changedSwaps: D["Swap"][]; removeSwaps: D["Swap"][]; }>

Inherited from

IEscrowSwapWrapper.checkPastSwaps


init()

init(noTimers, noCheckPastSwaps): Promise<void>;

Defined in: atomiq-sdk/src/swaps/ISwapWrapper.ts:314

Initializes the swap wrapper, needs to be called before any other action can be taken

Parameters

ParameterTypeDefault valueDescription
noTimersbooleanfalseWhether 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
noCheckPastSwapsbooleanfalseWhether 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>

Inherited from

IEscrowSwapWrapper.init


recoverFromSwapDataAndState()

abstract recoverFromSwapDataAndState(
init,
state,
lp?): Promise<D["Swap"]>;

Defined in: atomiq-sdk/src/swaps/escrow_swaps/IEscrowSwapWrapper.ts:231

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

ParameterTypeDescription
init{ data: T["Data"]; getInitTxId: () => Promise<string>; getTxBlock: () => Promise<{ blockHeight: number; blockTime: number; }>; }Swap escrow initialization transaction and swap data
init.dataT["Data"]-
init.getInitTxId() => Promise<string>-
init.getTxBlock?() => Promise<{ blockHeight: number; blockTime: number; }>-
state?SwapCommitStateCurrent on-chain state of the swap
lp?IntermediaryIntermediary (LP) used as a counterparty for the swap

Returns

Promise<D["Swap"]>

Inherited from

IEscrowSwapWrapper.recoverFromSwapDataAndState


stop()

stop(): Promise<void>;

Defined in: atomiq-sdk/src/swaps/ISwapWrapper.ts:355

Un-subscribes from event listeners on the smart chain, terminates the tick interval and stops this wrapper

Returns

Promise<void>

Inherited from

IEscrowSwapWrapper.stop


tick()

tick(swaps?): Promise<void>;

Defined in: atomiq-sdk/src/swaps/ISwapWrapper.ts:396

Invokes ISwap._tick on all the known swaps

Parameters

ParameterTypeDescription
swaps?D["Swap"][]Optional array of swaps to invoke _tick() on, otherwise all relevant swaps will be fetched from the persistent storage

Returns

Promise<void>

Inherited from

IEscrowSwapWrapper.tick
