eth_call

Summary: Execute a new message call

This request executes a new message call without creating a transaction on the blockchain. It allows you to invoke a contract function locally to interact with smart contracts and query data without modifying the blockchain state or consuming gas. eth_call is ideal for retrieving data, simulating transactions, or testing contract interactions.

Parameters

transaction
object
required

Transaction object generic to all Linea-supported transactions. All transaction call object parameters are optional.

type
enum

The transaction type as introduced in EIP-2718, in hexadecimal. Use:

  • 0x00 for LegacyTxType
  • 0x01 for AccessListTxType (EIP-2930)
  • 0x02 for DynamicFeeTxType (EIP-1559)

Enum:
"0x00"
"0x01"
"0x02"
nonce
string

Account nonce; counter for the number of transactions sent from the account; for replay protection.

Pattern: ^0x([1-9a-f]+[0-9a-f]*|0)$

to
oneOf

Address of the action receiver.

Contract Creation (null)
null

Contract Creation (null)

Address
string

Hex-encoded address.

Pattern: ^0x[0-9a-fA-F]{40}$

from
string

Address of the sender.

Pattern: ^0x[0-9a-fA-F]{40}$

gas
string

Gas provided by the sender. eth_call consumes zero gas, but this schema supports other executions that might need this parameter. eth_estimateGas ignores this value.

Pattern: ^0x([1-9a-f]+[0-9a-f]*|0)$

value
string

Value to transfer in wei.

Pattern: ^0x([1-9a-f]+[0-9a-f]*|0)$

input
string

Input data; alternative term for data.

Pattern: ^0x[0-9a-f]*$

gasPrice
string

The gas price the sender is willing to pay in wei. Used only in non-EIP-1559 transactions.

Pattern: ^0x([1-9a-f]+[0-9a-f]*|0)$
Default: 0x0

maxPriorityFeePerGas
string

Maximum fee, in wei, the sender is willing to pay per gas above the base fee. Can be used only in EIP-1559 transactions. If used, must specify maxFeePerGas.

Pattern: ^0x([1-9a-f]+[0-9a-f]*|0)$

maxFeePerGas
string

Maximum total fee (base fee + priority fee), in wei, the sender is willing to pay per gas. Can be used only in EIP-1559 transactions. If used, must specify maxPriorityFeePerGas.

Pattern: ^0x([1-9a-f]+[0-9a-f]*|0)$

accessList
array

EIP-2930 access list; a list of addresses and storage keys that the transaction plans to access.

object

Access list entry.

address
string

Hex-encoded address.

Pattern: ^0x[0-9a-fA-F]{40}$

storageKeys
array

string

32 byte hex value.

Pattern: ^0x[0-9a-f]{64}$

chainId
string

Chain ID that this transaction is valid on.

Pattern: ^0x([1-9a-f]+[0-9a-f]*|0)$

block
anyOf

Block number, block hash, or string tag.

Block number
string

Block number in hexadecimal.

Pattern: ^0x([1-9a-f]+[0-9a-f]*|0)$

Block tag
enum

See the default block parameter.

  • earliest: The lowest numbered block the client has available.
  • latest: The most recent block in the canonical chain observed by the client, this block may be re-orged out of the canonical chain even under healthy/normal conditions.
  • pending: A sample next block built by the client on top of latest and containing the set of transactions usually taken from local mempool.

Enum:
"earliest"
"latest"
"pending"
Block hash
string

32 byte hex value.

Pattern: ^0x[0-9a-f]{64}$

Returns

eth_callResponse
string

Note that, an execution reverted message suggests that the transaction would fail on-chain or that the contract logic has conditions that aren't met when simulating the transaction.

Pattern: ^0x[0-9a-f]*$
