How to Reduce Solana RPC Costs

If you're building on Solana, you've probably noticed your RPC bill climbing fast. This guide explains where those costs come from and how to cut them dramatically.

Why Solana RPC Is Expensive

Every interaction with the Solana blockchain goes through an RPC node. Most providers charge per compute unit (CU), and the costs add up quickly:

RPC Call	Typical CU Cost	How Often You Call It
getAccountInfo	100 CU	Every price check, every pool read
getProgramAccounts	10,000+ CU	Scanning pools, finding positions
sendTransaction	200 CU	Every swap, every trade
simulateTransaction	500 CU	Pre-flight checks

The biggest cost driver for most Solana applications is polling for price and pool data. A bot checking 20 token prices every second racks up thousands of RPC calls per minute — and that's before you even submit a transaction.

The Real Numbers

Here's what typical Solana RPC costs look like at scale:

Use Case	RPC Calls/Day	Monthly Cost (Paid RPC)
Simple wallet app	~10,000	$5-15
Price dashboard (20 tokens)	~500,000	$50-150
Trading bot (active)	~2,000,000	$200-500
DEX aggregator	~10,000,000+	$500-2,000+

Most of this comes from two patterns:

1. Polling pool accounts to compute swap prices
2. Polling token accounts to track balances and prices

How to Cut RPC Costs

1. Stop Polling for Prices

Instead of calling getAccountInfo in a loop, use a streaming API that pushes prices to you as they change.

Venum's SSE price streams deliver sub-second price updates over a single HTTP connection. One stream replaces hundreds of RPC calls per minute.

// Before: polling (expensive)
setInterval(async () => {
  const account = await connection.getAccountInfo(poolAddress);
  const price = decodePrice(account);
}, 1000);

// After: streaming (free with Venum)
const source = new EventSource('https://api.venum.dev/v1/stream/prices?tokens=SOL');
source.addEventListener('price', (e) => {
  const { priceUsd } = JSON.parse(e.data);
});

2. Eliminate getProgramAccounts

getProgramAccounts is the most expensive RPC call on Solana. A single call can consume 10,000+ CU and take seconds to return. If you're using it to discover pools or scan for positions, you're burning money.

Venum maintains a complete pool index updated from live on-chain state. Query it via REST:

# Get all SOL/USDC pools across every DEX
curl https://api.venum.dev/v1/pools?pair=SOL,USDC

No getProgramAccounts. No CU cost. Cached and fast.

2.1. Keep expensive discovery opt-in

If you already have a warm snapshot plus live Geyser updates, repeated rediscovery is usually wasted RPC.

Current runtime defaults keep the expensive discovery loops off unless you explicitly turn them back on:

• ENABLE_STARTUP_BULK_DISCOVERY=0
• ENABLE_STARTUP_MINT_DISCOVERY=0
• ENABLE_POOL_ARB_WARM_REFRESH=0
• ENABLE_POOL_ARB_PERIODIC_DISCOVERY=0
• ENABLE_PROTOCOL_ARB_DISCOVERY=0

This keeps the hot path focused on live updates instead of paying recurring discovery costs.

3. Let Someone Else Submit Transactions

Every sendTransaction call costs CU and requires a healthy RPC connection. If you're also simulating before sending, that's double the cost.

Venum's swap submission handles this for you:

• Builds optimized transactions with correct compute budgets
• Submits through Venum's landing fan-out instead of a single RPC
• Pre-confirmation visibility (~200ms) — faster than RPC polling for confirmation
• Retry logic built in

You go from 3-4 RPC calls per swap (simulate + send + confirm + retry) to 1 API call.

4. Cache Aggressively on Your Side

For data that doesn't change every second (token lists, pool metadata, supported markets), cache it locally. Venum's free endpoints include built-in caching:

• /v1/tokens — 60-second cache
• /v1/pools — 5-second cache
• /v1/prices — 2-second cache

These are free and unauthenticated. Use them as your cache source.

Cost Comparison

Approach	Monthly Cost	Latency	Maintenance
Self-hosted node	$500-2,000	~50ms	High (DevOps required)
Helius / Triton / QuickNode	$50-500	~15ms	Medium (manage rate limits)
Free RPC (public)	$0	~200ms+	None (but unreliable)
Venum API	$0-199	<10ms	None

When You Still Need RPC

Venum doesn't replace RPC entirely — it eliminates the most expensive patterns. You'll still want an RPC connection for:

• Account-specific queries — checking your wallet balance, fetching specific token accounts
• Program interactions beyond swaps — staking, governance, custom programs
• Historical data — transaction history, block data

The goal is to route 80-90% of your RPC calls through a purpose-built API and keep your raw RPC usage to a minimum.

Getting Started

1. Sign up for a free API key — no credit card required
2. Replace your price polling loops with SSE price streams
3. Replace getProgramAccounts for pool data with /v1/pools
4. Route swaps through /v1/swap instead of building and submitting yourself

Most developers cut their RPC costs by 70-90% within the first week.
