eth_call - Moonbeam RPC Method
Execute smart contract calls without creating transactions on Moonbeam. Essential for reading contract state for cross-chain DeFi, multi-chain dApps, and Ethereum-to-Polkadot bridging via XCM, Axelar, LayerZero, and Wormhole.
Executes a new message call immediately without creating a transaction on Moonbeam. Used for reading smart contract state.
Why Moonbeam? Build on the cross-chain connected EVM platform on Polkadot with $65M+ TVL and 100+ projects with full EVM compatibility on Polkadot, native XCM cross-chain messaging, 10K+ TPS, 24% staking APR, and $0.015 transaction costs.
Use Cases
The eth_call method is essential for:
- Reading contract state - Query view/pure functions
- Simulating transactions - Test execution without gas costs
- DeFi integrations - Check prices, balances, allowances for cross-chain DeFi, multi-chain dApps, and Ethereum-to-Polkadot bridging via XCM, Axelar, LayerZero, and Wormhole
- Complex queries - Execute multi-step contract logic
