Silvia Web 3 Providers

A Web based crypto wallet to connect Silvia Blockchain apps.

You can use it to connect to the Silvia.link blockchain network and sign transactions without a private key.

Usage

import { WebSocketProvider, JsonRpcProvider } from '@sw3/providers'
import { Contract } from '@ethersproject/contracts'
// Provider
const provider = new WebSocketProvider('wss://rpc.silvia.link/ws')
// Signer
const account = await provider.send('eth_requestAccounts')
const contract = new Contract(contractAddress, abi, provider.getSigner(account))

Account Caching

If you're using a reactive framework like vue/react, you can maintain the state by yourself:

const provider = new WebSocketProvider('wss://rpc.silvia.link/ws')
const state = { account: provider.account }
provider.SW3.on('accountsChanged', () => {
	state.account = provider.account
})

By default, SW3 caches account address using sessionStorage (provider.SW3.account) in convenience, you can disable it by changing the option setting to {cache: false}. eg:

const provider = new WebSocketProvider('wss://rpc.silvia.link/ws', undefined, { cache: false })
