Solana RPC Proxy

Overview

BoltTx exposes a Solana JSON-RPC compatible endpoint so you can migrate from your existing RPC provider with a single URL change. The proxy accepts the sendTransaction method and forwards it through our optimized delivery infrastructure.

Supported Methods

For queries (getAccountInfo, getBalance, etc.), keep using your regular Solana RPC endpoint. BoltTx is focused on fast, reliable transaction delivery — not general-purpose RPC.

Usage Example

import { Connection } from "@solana/web3.js";

// Drop-in replacement — just swap your RPC URL
const connection = new Connection(
  "https://bolttx.io/?api-key=YOUR_API_KEY",
  "confirmed"
);

// Your existing sendRawTransaction code continues to work
const signature = await connection.sendRawTransaction(
  signedTx.serialize(),
  { skipPreflight: true }
);

console.log("Signature:", signature);
