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.
