eth_call - Arbitrum

Executes a new message call immediately without creating a transaction on the block chain.

Parameters

  • Object - The transaction call object.
    • from: DATA, 20 Bytes - (optional) The address the transaction is sent from.
    • to: DATA, 20 Bytes - The address the transaction is directed to.
    • gas: QUANTITY - (optional) Integer of the gas provided for the transaction execution. eth_call consumes zero gas, but this parameter may be needed by some executions. NOTE: this parameter has a cap of 550 million Gwei per request. Reach out to us at [email protected] if you want to increase this limit.
    • gasPrice: QUANTITY - (optional) Integer of the gasPrice used for each paid gas. Note: most of our users (95%+) never set the gasPrice on eth_call.
    • value: QUANTITY - (optional) Integer of the value sent with this transaction
    • data: DATA - (optional) Hash of the method signature and encoded parameters. For details see the Contract ABI.
  • QUANTITY|TAG - integer block number, or the string "latest", "earliest" or "pending", see the default block parameter.

❗️

Note

eth_call has a timeout restriction at the node level. Batching multiple eth_calls together on-chain using pre-deployed smart contracts might result in unexpected timeouts that cause none of your calls to complete. Instead, consider serializing these calls, or using smaller batches if they fail with a node error code.
