eth_call

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

Gas parameter is capped

To prevent API abuse, the gas parameter in eth_estimateGas and this eth_call method is capped at 10x (1000%) the current block gas limit.

Parameters​

  • from: 20 bytes [Required] Address the transaction is sent from.
  • to: 20 bytes - Address the transaction is directed to.

  • gasPrice: Hexadecimal value of the gasPrice used for each paid gas.
  • maxPriorityFeePerGas: Maximum fee, in wei, the sender is willing to pay per gas above the base fee. See EIP-1559 transactions.
  • maxFeePerGas: Maximum total fee (base fee + priority fee), in wei, the sender is willing to pay per gas. See EIP-1559 transactions.
  • value: Hexadecimal of the value sent with this transaction.
  • data: Hash of the method signature and encoded parameters. See Ethereum contract ABI specification.
  • block parameter: [Required] A hexadecimal block number, or one of the string tags latest, earliest, pending, safe, or finalized. See the default block parameter.
