Constructors

Constructor

new Intermediary(
   url, 
   addresses, 
   services, 
   reputation): Intermediary;

Defined in: atomiq-sdk/src/intermediaries/Intermediary.ts:98

Parameters

Parameter	Type
url	string
addresses	{ [chainIdentifier: string]: string; }
services	ServicesType
reputation	{ [chainIdentifier: string]: SingleChainReputationType; }

Returns

Intermediary

Properties

addresses

readonly addresses: object;

Defined in: atomiq-sdk/src/intermediaries/Intermediary.ts:57

Addresses of the intermediary on smart chains, used for checking the provided signatures

Index Signature

[chainIdentifier: string]: string

---

liquidity

liquidity: object = {};

Defined in: atomiq-sdk/src/intermediaries/Intermediary.ts:90

Liquidity of the intermediary across different smart chains, this is only fetched on-demand when creating a swap where intermediary's liquidity is checked

Index Signature

[chainIdentifier: string]: SCLiquidity

---

lnData?

optional lnData: LNNodeLiquidity;

Defined in: atomiq-sdk/src/intermediaries/Intermediary.ts:96

Data about a lightning network node used by this intermediary, if it offers lightning network swaps, this is only fetched on-demand when creating a Bitcoin Lightning -> Smart chain swap through the intermediary (which necessitates checking intermediary's channel capacities)

---

reputation

reputation: object = {};

Defined in: atomiq-sdk/src/intermediaries/Intermediary.ts:85

Reputation of the intermediary on different smart chains, this is only fetched on-demand when creating a swap where reputation is checked

Index Signature

[chainIdentifier: string]: SingleChainReputationType

---

services

readonly services: ServicesType;

Defined in: atomiq-sdk/src/intermediaries/Intermediary.ts:61

Swap protocol services offered by the intermediary

---

swapBounds

readonly swapBounds: object;

Defined in: atomiq-sdk/src/intermediaries/Intermediary.ts:65

Input/output swap bounds for various swap protocols offered by the intermediary
