Klaytn ProviderEngine

Klaytn ProviderEngine is a tool for composing your own klaytn providers.

Originally created for MetaMask and Ethereum, but forked by Kompose for Klaytn usage.

Composable

Built to be modular - works via a stack of 'sub-providers' which are like normal web3 providers but only handle a subset of rpc methods.

The subproviders can emit new rpc requests in order to handle their own; e.g. klay_call may trigger klay_getAccountBalance, klay_getCode, and others. The provider engine also handles caching of rpc request results.

const ProviderEngine = require('@kompose-app/klaytn-provider-engine')

// cache layer
engine.addProvider(new CacheSubprovider())

// filters
engine.addProvider(new FilterSubprovider())

// pending nonce
engine.addProvider(new NonceSubprovider())

// vm
engine.addProvider(new VmSubprovider())

When importing in webpack:

import * as Web3ProviderEngine  from 'web3-provider-engine';
