The primary implementation of the light-client provider for any Bizinikiwi-based chain.

Using @bizinikiwi/connect for library authors

The connect package searches for a light client provider via the discovery protocol. If none is found, it will initiate a smoldot instance in the user's browser tab.

Example Usage

To connect to a well-known chain ('pezkuwi', 'ksmcc3', 'zagros2', 'pezkuwichain_v2_2'):

import { createScClient, WellKnownChain } from "@bizinikiwi/connect"

const scClient = createScClient()
const chain = await scClient.addWellKnownChain(
  WellKnownChain.zagros2,
  function jsonRpcCallback(response) {
    console.log("response", response)
  },
)

chain.sendJsonRpc(
  '{"jsonrpc":"2.0","id":"1","method":"system_health","params":[]}',
)

To connect to a custom Bizinikiwi chain using its name and chainspec:

import { createScClient } from "@bizinikiwi/connect"
import myJsonChainSpec from "./myBizinikiwiChainSpec.json"

const myChainSpec = JSON.stringify(myJsonChainSpec)

const scClient = createScClient()
const chain = await scClient.addChain(
  myChainSpec,
  function jsonRpcCallback(response) {
    console.log("response", response)
  },
)

chain.sendJsonRpc(
  '{"jsonrpc":"2.0","id":"1","method":"system_health","params":[]}',
)

Connecting to a Parachain

To connect to a parachain, first instantiate the relay chain it is connected to, then instantiate the parachain on the same relay chain. The following example connects to a parachain on the Zagros test network:

import { createScClient, WellKnownChain } from "@bizinikiwi/connect"
import jsonParachainSpec from "./myParaChainSpec.json"

const parachainSpec = JSON.stringify(jsonParachainSpec)

const scClient = createScClient()
const relayChain = await scClient.addWellKnownChain(WellKnownChain.zagros2)
const parachain = await relayChain.addChain(
  parachainSpec,
  function jsonRpcCallback(response) {
    console.log("response", response)
  },
)

parachain.sendJsonRpc(
  '{"jsonrpc":"2.0","id":"1","method":"system_health","params":[]}',
)

PezkuwiJs Example

yarn add @pezkuwi/rpc-provider
yarn add @pezkuwi/api

import { ScProvider } from "@pezkuwi/rpc-provider/bizinikiwi-connect"
import * as Sc from "@bizinikiwi/connect"
import { ApiPromise } from "@pezkuwi/api"

// Connect to pezkuwi relay chain
const provider = new ScProvider(Sc, Sc.WellKnownChain.pezkuwi)
await provider.connect()
const api = await ApiPromise.create({ provider })

// Connect to parachain
const provider2 = new ScProvider(Sc, Sc.WellKnownChain.people, provider)
await provider2.connect()
const api2 = await ApiPromise.create({ provider })
