BoltRPC

Overview

BoltRPC is a multi-chain RPC platform operated by Matrixed.Link that provides HTTPS and WebSocket access to Avalanche C-Chain (chain ID 43114). Developers connect with a single API key pattern and use standard JSON-RPC clients without a custom SDK.

Features

• Avalanche C-Chain RPC: Standard JSON-RPC 2.0 over HTTPS for reads, writes, and logs
• WebSocket subscriptions: Real-time block, transaction, and event streams over wss
• Request-unit pricing: Published method weights with flat monthly plans
• Certified infrastructure: Runs on Matrixed.Link ISO/IEC 27001:2022 certified node infrastructure
• Multi-chain API key: One key pattern across supported networks, including Avalanche via the avax slug
• Client compatible: Works with ethers.js, viem, web3.py, Foundry, and raw HTTP clients

Getting Started

1. Create an API key at dashboard.boltrpc.io (trial at trial.boltrpc.io).
2. Point your client at the Avalanche C-Chain endpoint:

import { ethers } from "ethers";

const provider = new ethers.JsonRpcProvider(
  "https://endpoints.boltrpc.io/rpc/YOUR_API_KEY/avax"
);

3. Optional WebSocket:

wss://endpoints.boltrpc.io/ws/YOUR_API_KEY/avax

Replace YOUR_API_KEY with your dashboard key. Avalanche C-Chain ID is 43114.

Use Cases

• dApps and wallets: Connect applications to Avalanche C-Chain through EVM-compatible RPC methods
• Indexers and bots: High-volume eth_call / eth_getLogs workloads with published RU pricing
• Enterprise deployments: Teams that need certified infrastructure for Avalanche C-Chain access
