Infura Connector

WHAT IT DOES

Infura Connector is a developer tool that tests and connects to Infura's Ethereum and EVM-compatible network endpoints. Enter your Infura Project ID, optionally add your API Secret, select a network (Mainnet, Goerli, Sepolia, Polygon, Arbitrum, or Optimism), and the tool establishes a connection to Infura's API. It displays the connection status, project ID, network name, chain ID, latest block number, and Infura client version. The tool also includes a "Test connection" button that verifies the endpoint without fully connecting. This is essential for developers configuring Infura in their applications, debugging connection issues, validating API keys, or learning how to connect to Infura's infrastructure.

HOW TO USE

Connect your wallet using the BGWallet bridge (MetaMask or any Web3 wallet). Enter your Infura Project ID in the input field — you can obtain one by signing up at infura.io. Optionally, enter your API Secret if you have one (not required for basic read operations). Select the network you want to connect to — Mainnet, Goerli, Sepolia, Polygon, Arbitrum, or Optimism. Click "Connect to Infura" to establish a connection and display network information. The tool will attempt to connect to the Infura endpoint and retrieve the chain ID, latest block number, and client version. Use the "Test connection" button to quickly verify if your Project ID is valid without fully setting up the connection. Results display the connection status, project ID, network name, chain ID, block number, and Infura version.

TECHNICAL MECHANISM

The tool uses ethers.js to create a JsonRpcProvider with the Infura endpoint URL. The URL is constructed as https://{network}.infura.io/v3/{projectId} (or with authentication if a secret is provided). It then calls provider.getNetwork() to retrieve the chain ID, provider.getBlockNumber() to get the latest block, and sends a web3_clientVersion RPC request to get the Infura client version. The tool measures the connection time and validates the response. If the connection fails, it captures the error and displays the failure reason. All operations are performed client-side — no data is stored or transmitted beyond the API request to Infura. The tool does not use or require the BGWallet provider for Infura connections — it creates its own independent JsonRpcProvider.

WHAT IT CANNOT SEE

The tool cannot connect to Infura without a valid project ID or API key — the Project ID is required for all Infura API requests. It cannot store or manage Infura API keys securely beyond the current browser session — keys are not persisted across page reloads. It cannot provide full Infura SDK functionality beyond basic connection and read operations — it does not support IPFS uploads, file storage, or advanced API features. It cannot handle rate limiting or quota management automatically — you must monitor your usage through the Infura dashboard. It cannot connect to Infura IPFS gateway without additional configuration — the tool only supports Ethereum network endpoints. It cannot detect network-specific issues (e.g., wrong network ID, unsupported endpoints) without testing. The tool does not sign any transactions.

PLEASE NOTE

This tool works exclusively with EVM-compatible networks supported by Infura (Ethereum Mainnet, Goerli, Sepolia, Polygon, Arbitrum, Optimism, and others). Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported. The tool does not store any data — all operations are performed client-side. The tool is provided as-is with no warranty or liability. Always verify your Infura Project ID from the Infura dashboard. Rate limits apply based on your Infura plan.
