);About Moonbeam
Connect your dApp, bot, or protocol to Moonbeam Mainnet with BoltRPC. Cross-chain infrastructure running across Polkadot and Ethereum ecosystems needs a single provider that supports both Moonbeam and Moonriver with consistent infrastructure and pricing.

Moonbeam is Polkadot’s primary Ethereum-compatible parachain. It bridges Ethereum tooling to the Polkadot ecosystem, enabling cross-chain protocols that need Polkadot interoperability with EVM developer experience. XCM (Cross-Consensus Messaging) allows Moonbeam to send and receive assets and data to other Polkadot parachains, making it the hub for multi-chain Polkadot deployments that also want Ethereum tooling. Protocols building cross-chain applications use Moonbeam as their Ethereum-compatible anchor point in the Polkadot ecosystem. The chain’s DeFi ecosystem includes protocols migrated from Ethereum and Polkadot-native applications.
Moonbeam is a Polkadot parachain with full EVM compatibility, but developers coming from standard EVM chains should understand a few architectural differences. Parachain block production is tied to Polkadot’s relay chain slot cadence, approximately 12 seconds, which is structurally fixed. Unlike standalone EVM chains that can adjust block times through governance, Moonbeam’s 12-second cadence is a function of its parachain design. Plan your polling intervals and WebSocket subscriptions accordingly.
XCM (Cross-Consensus Messaging) is Moonbeam’s cross-chain protocol for passing assets and messages to other Polkadot parachains. From an RPC perspective, XCM interactions on Moonbeam are accessed through precompiled contracts at fixed addresses on the EVM. You call these precompiles using the same eth_call and eth_sendRawTransaction methods as standard EVM contracts. However, the execution path reaches across to other parachains, which means some operations have longer confirmation paths than a standard single-chain EVM call.
Moonbeam’s EVM precompiles expose Polkadot-native functionality including staking, XCM messaging, and governance. Developers who want to build applications that bridge the Ethereum and Polkadot ecosystems should review Moonbeam’s precompile registry for addresses and ABIs before starting development.
Why BoltRPC
Teams building cross-chain applications on Moonbeam need to test on Moonriver (Moonbeam's Kusama canary) before deploying to Moonbeam mainnet. BoltRPC supports both networks from one provider with one API key. Switch one environment variable when promoting from Moonriver to Moonbeam.
Moonbeam is a Polkadot parachain with full EVM compatibility. XCM cross-chain messaging generates more RPC activity than standard single-chain apps. Your RPC needs to handle both standard EVM calls and cross-chain state reads reliably.
Moonbeam connects Ethereum tooling to Polkadot's parachain ecosystem. Projects building multi-chain deployments require stable RPC on Moonbeam as a core dependency. Unreliable RPC breaks cross-chain workflows that may span multiple parachains.
Any Ethereum code works on Moonbeam with a single endpoint change. The same JSON-RPC methods, libraries, and tooling apply. XCM functionality is accessed through Moonbeam-specific precompiles using the same EVM interface.
XCM-based applications generate eth_getLogs queries to track cross-chain message events alongside standard EVM calls. Published per-method request-unit pricing means your cross-chain call patterns do not create billing surprises.
Subscribe to Moonbeam events in real time via WebSocket. Essential for monitoring XCM message delivery and parachain state changes.
