ethers read-only provider

Read-only JsonRpcProvider example generated from Main.net fields. It does not create a signer.

import { JsonRpcProvider } from 'ethers'

export const provider = new JsonRpcProvider("https://mainnet.hashio.io/api", {

console.log(network.chainId)

bash

curl eth_chainId check

Minimal JSON-RPC identity check. This verifies the endpoint-reported chain ID only, not uptime or production suitability.

curl -s -X POST \
  -H 'content-type: application/json' \
  --data '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}' \
  https://mainnet.hashio.io/api

# Expected chain ID: 295 / 0x127

Developer signals

External dashboards a developer may inspect before choosing where to deploy. Main.net links to these references but does not collect the metric values, normalize methodologies, rank chains, or recommend deployments.

explorerHedera explorerExplorer-hosted blocks, transactions, contracts, token transfers, and verification tools from the listed explorer.

Main.net links to external developer-signal dashboards but does not collect, normalize, rank, or republish their metric values in this version.
External metrics can use different methodologies and update schedules. Check the linked provider documentation before comparing chains.
These links are not recommendations, rankings, investment advice, or claims that a chain is suitable for a specific application.

Safety note

Hedera documentation identifies Hashio as the mainnet RPC endpoint for wallet setup. Confirm provider limits and status before using it for production traffic.

Main.net is an independent reference site. It does not operate this chain, custody assets, execute transactions, or provide investment advice.
