Usage
Create and manage a Zap Provider
npm install `@zapjs/provider`
import {ZapProvider, ProviderHandler} from '@zapjs/provider';
let myZapProvider = new ZapProvider({owner:address});
Create Zap Provider
let myZapProvider = new zapProvider(owner)
With Custom configuration
let myZapProvider = new ZapProvider(owner,{networkId,networkProvider,coordinator});
Initiate in Registry and create Curve for an endpoint
await myZapProvider.initiateProvider({
public_key:111,
title: "testTitle",
endpoint: "testEndpoint",
endpoint_params : ["p1","p2"]
})
const thisConstants = []
const thisParts = []
const thisDividers = []
await myZapProvider.initiateProviderCurve({
endpoint :"testEndpoint",
constants : thisConstants,
parts : thisParts,
dividers : thisDividers
})
Get information about a provider
Get general information
const title = await myZapProvider.getTitle()
const pubkey = await myZapProvider.getPubkey()
TODO get next endpoint
Get endpoint specific information
const Curve = await myZapProvider.getCurve(endpoint);
const zapBound = await myZapProvider.getZapBoung(endpoint);
const zapRequired = await myZapProvider.getZapRequired({endpoint,dots});
const dots = await myZapProvider.calcDotsForZap({endpoint,zapAmount})
Listen to events belong to this provider
myZapProvider.listenSubscribes(filters,callback);
myZapProvider.listenUnsubscribes(filters,callback);
myZapProvider.listenQueries(filters,callback);
