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

  • 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.

The returned value of the executed contract.

If this call causes the EVM to execute a REVERT operation, an error response of the following form is returned, with the revert reason pre-decoded as a string:

"jsonrpc": "2.0",
"id": 1,
"error": {
"code": 3,
"message": "execution reverted: Dai/insufficient-balance",
"data": "0x08c379a0000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000184461692f696e73756666696369656e742d62616c616e63650000000000000000"
