Scroll RPC Endpoint and API

Scroll is a zkEVM Layer 2 that scales Ethereum with zero-knowledge proofs while preserving EVM compatibility and Ethereum settlement. It gives DeFi, wallets, games, and other smart-contract apps lower-cost execution without changing familiar tooling.

Scroll RPC Endpoints

Quick RPC check

Start with eth_blockNumber and eth_chainId, then test contract reads, logs, receipts, transaction submission, WebSocket reconnects, and historical queries required by your application.

What to validate before production

Check EVM compatibility, response latency, log and receipt behavior, WebSocket stability, archive access, retry handling, and whether traffic growth requires authenticated or dedicated capacity.

Scroll RPC use cases

Scroll RPC supports DeFi applications, wallets, analytics dashboards, bots, games, trading systems, and backend services that use Ethereum tooling while targeting an L2 network.

Scroll production workflow

Use a test environment for contract and wallet QA, then repeat block, contract, log, receipt, transaction, and WebSocket checks on Scroll Mainnet before launch. Keep an upgrade path ready for traffic-heavy or operationally sensitive workloads.
