SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides raw multi-chain JSON-RPC access to blockchain data through BlockRun's gateway. This enables developers to query contracts, balances, blocks, logs, and gas estimates without running their own nodes.

Core Features & Use Cases

  • Single-endpoint access per network via BlockRun's gateway for 40+ chains.
  • Supports standard JSON-RPC 2.0 calls and batched requests with per-element billing.
  • Use-case: fetch latest block data, read contract state, or query wallet balances across networks.

Quick Start

Call blockrun_rpc with a network and a valid JSON-RPC body to perform a read query.

FAQPage Schema
How do I query blockchain data without running my own node?

You can query blockchain data without a node by sending standard JSON-RPC 2.0 calls through a gateway endpoint. This Skill supports contract reads, balances, blocks, logs, and gas estimates across 40+ chains with no node provisioning required.

Do I need an API key to make JSON-RPC calls to EVM networks?

No API key is needed to make JSON-RPC calls. The gateway provides single-endpoint access to 40+ EVM-compatible networks, caches identical read responses, and requires no authentication setup or node management.

Can I send batched JSON-RPC requests for multi-chain contract reads?

Yes, you can send batched JSON-RPC requests for multi-chain contract reads. The gateway supports standard JSON-RPC 2.0 batched calls and handles billing on a per-element basis for each request in the batch.

What's the best way to fetch wallet balances and block data across multiple web3 chains?

The best way to fetch wallet balances and block data across multiple web3 chains is using a multi-chain JSON-RPC gateway. It routes standard read queries to the specified network, returning raw blockchain data without node management overhead.

Does this multi-chain RPC gateway support gas estimates and log queries?

Yes, the multi-chain RPC gateway supports gas estimates and log queries. It processes standard JSON-RPC 2.0 method calls to fetch event logs, estimate gas costs, and read contract state across 40+ supported blockchain networks.
