FREE PUBLIC RPC IS NOT FREE
CONSTANT DOWNTIME
Free public endpoints go down during peak traffic. Your dApp stops working exactly when users need it most.
AGGRESSIVE RATE LIMITS
5 requests per second on a public endpoint. Your indexer crawls. Your bot misses opportunities. Your users wait.
NO SUPPORT
Something breaks at 2 AM. There is no one to call. No SLA. No accountability. You are on your own.
INCONSISTENT PERFORMANCE
Fast one minute, slow the next. 50ms response time turns into 2 seconds when everyone else hits the same endpoint.
SINGLE CHAIN LOCK-IN
Each chain has its own free endpoint with different reliability. Multi-chain apps need a consistent provider.
NO STREAMING
Most free endpoints only support HTTP. No WebSocket subscriptions, no gRPC streams. You are stuck polling in a loop and wasting requests.
WHY TEAMS CHOOSE
SUPANODE RPC
RPC infrastructure that works when free endpoints don't.
Running a blockchain application on free public RPC is like hosting a production website on your local machine. It works until it doesn't. Supanode RPC endpoints run on infrastructure in top-tier datacenters next to validator clusters. You get consistent performance, generous rate limits, and support when something goes wrong.
7 CHAINS, ONE PROVIDER
Solana, Ethereum, BNB Chain, Arbitrum, Base, Hyperliquid, Monad. One account, one dashboard, consistent quality.
99.99% UPTIME SLA
Infrastructure that stays online when free endpoints fail. Backed by a real SLA with real accountability.
LOW LATENCY
Nodes in Frankfurt, Amsterdam, New York. Under 1ms on Solana, sub-50ms on EVM chains. Fast reads, fast writes.
GENEROUS RATE LIMITS
Enough throughput for development, testing, and moderate production. No 5 req/s caps.
REAL-TIME STREAMING
WebSocket subscriptions and gRPC streams included. Account changes, new blocks, transaction confirmations pushed to your app. No polling.
STANDARD INTERFACES
JSON-RPC over HTTP and WebSocket. Compatible with web3.js, ethers.js, solana-web3.js, viem. No proprietary SDK.
BUILT FOR
BUILDERS
From weekend projects to production applications.
Whether you are building a dApp frontend, running a trading bot, or setting up an analytics pipeline, you need RPC that works. Not RPC that works sometimes. Our endpoints serve everything from weekend projects to production applications handling thousands of requests per minute.
dApp FRONTENDS
Wallet connections, transaction signing, balance queries. Your users get fast responses without timeout errors.
TRADING BOTS
Price feeds, transaction submission, account monitoring. Enough throughput to run strategies without rate limit anxiety.
ANALYTICS PIPELINES
Historical data queries, transaction scanning, token tracking. Consistent performance for data ingestion.
BACKEND SERVICES
Payment processing, notification systems, on-chain verification. Reliable RPC for your server-side logic.
DEVELOPMENT & TESTING
Build and test without free endpoint instability. Same endpoints, same behavior, dev to production.
MULTI-CHAIN APPS
Cross-chain bridges, aggregators, portfolio trackers. One provider for all your chains.
