eth_call

Executes a new message call immediately without creating a transaction on the blockchain. This method uses 80 credits from your daily balance.

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.

• TRANSACTION CALL OBJECT [Required]
  • from: 20 bytes [Required] Address the transaction is sent from.
  • to: 20 bytes - Address the transaction is directed to.
  • gas: Hexadecimal value of the gas provided for the transaction execution. eth_call consumes zero gas, but this parameter may be needed by some executions.
  • 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.

  • value: Hexadecimal of the value sent with this transaction.
