RPC Accelerator

RPC Accelerator PricingAccelerator enhances performance by serving cached blockchain data when available.

1 creditcache hit – served instantly from blockchain data cache

0 creditscache miss – request goes to RPC node (RPC pricing applies)

RPC Accelerator dramatically improves read-performance across all supported chains by serving responses directly from tip-level cached blockchain data rather than waiting for full nodes to recompute the same information repeatedly. This results in ultra-fast rpc apis, smoother application performance, and significantly lower latency during traffic spikes.

By caching frequently accessed data — such as block headers, balances, receipts, and transactions — the RPC Gateway can return results instantly without repeatedly querying upstream endpoint providers.

🚀

Performance upgrade included: Most read calls targeting the tip of the chain are significantly faster when served from Tatum’s blockchain cache. The RPC Accelerator automatically enhances supported RPC methods with no configuration required.

How RPC Accelerator Works

Instead of resolving every request from an RPC node, the Accelerator strategically caches canonical chain-tip data across multiple internal layers. This eliminates redundant recomputation and significantly reduces response times for frequently accessed data.

Methods That Benefit Most

Due to the block-tip caching model, the following commonly used methods experience the most significant performance improvements when querying data from blocks created within the time windows shown below:

Equivalent blocks times on different chains for 4 hours

• Ethereum: ~1,200 blocks (avg. block time 12s)
• Polygon: ~7,200 (avg. block time, 2s)
• BSC: ~14,400 (avg. block time, 1s)
• Base: ~7,200 (avg. block time, 2s)
• Arbitrum: ~57,600 (avg. block time, 0.25s)

Sending an Accelerated RPC Request

Simply call your existing RPC methods against a Gateway with RPC Accelerator enabled:

curl -X POST https://ethereum-mainnet.gateway.tatum.io \
  -H "x-api-key: {YOUR_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
        "id": 1,
        "jsonrpc": "2.0",
        "method": "eth_getBlockByNumber",
        "params": ["latest", true]
      }'

The Accelerator detects supported methods automatically and returns cached results when safe.

Performance Gains

Reduced Latency

Depending on method and the block range being queried the performance is drastically improved. Generally improving the the performance by 3-4x for calls listed here.

Smooth High-Volume Traffic

Even during network congestion or analytics scraping, Accelerator:

• Shields providers from overload
• Eliminates rate-limit burst failures
• Provides stable low-latency results

Does RPC Accelerator Affect Data Freshness?

No – Accelerator only serves responses when the cached value matches the chain tip.

If the Gateway detects new chain data or block advancement:

• Cached values are invalidated
• The next request is resolved from a live provider
• Fresh data is immediately re-cached

✅

Data freshness is never compromised — RPC Accelerator never returns stale block data.
