Deprecation Notice

This method was deprecated on Amoy Testnet (July 1, 2026) and Mainnet (July 15, 2026) following Polygon Labs' sunset of Erigon. Use eth_simulateV1 as an alternative.

Parameters

array
array

An array with the following fields:

transactions
array

An array of transaction call objects

from
string

The address from which the transaction is sent

to
string
REQUIRED

The address to which the transaction is addressed

gas
integer

The integer of gas provided for the transaction execution

gasPrice
integer

The integer of gasPrice used for each paid gas encoded as hexadecimal

value
integer

The integer of value sent with this transaction encoded as hexadecimal

data
string

The hash of the method signature and encoded parameters. For more information, see the Contract ABI description in the Solidity documentation

maxFeePerGas
string

The maximum total fee per gas the sender is willing to pay encoded as hexadecimal

maxPriorityFeePerGas
string

The maximum priority fee per gas the sender is willing to pay encoded as hexadecimal

blockOverride
object

(Optional) The overrides of the execution context block header

blockNumber
string

The block number. Defaults to the block number of the first simulated block

blockHash
object

A dictionary that maps blockNumber to a user-defined hash. It could be queried from the solidity opcode BLOCKHASH

coinbase
string

The address of miner. Defaults to the original miner of the first simulated block.

timestamp
integer

The timestamp of the current block. Defaults to the timestamp of the first simulated block. Each following block increments its timestamp by 1.

difficulty
integer

The difficulty of the current block. Defaults to the difficulty of the first simulated block.

gasLimit
integer

The gas limit of the current block. Defaults to the difficulty of the first simulated block.

baseFee
integer

The base fee of the current block. Defaults to the base fee of the first simulated block.

simulationContext
object

(Optional) The simulation context

blockNumber
string

The Tag 'latest', 'earliest', 'pending', 'safe' or 'finalized', or a hexadecimal block number

transactionIndex
integer

The transaction index of the simulated transactions. Default value of the transaction index is -1, which would place the simulated transactions after the entire block.

STATE_OVERRIDE
object

(Optional) The State Override Set option allows you to change the state of a contract before executing the call, which means you can modify the values of variables stored in the contract, such as balances and approvals for that call without actually modifying the contract. Each address maps to an object containing:

balance
string

The fake balance to set for the account before executing the call

nonce
string

The fake nonce to set for the account before executing the call

code
string

The fake EVM bytecode to inject into the account before executing the call

state
object

The fake key-value mapping to override all slots in the account storage before executing the call

stateDiff
integer

The fake key-value mapping to override individual slots in the account storage before executing the call

timeout
integer

The upper limit running time for the simulations in milliseconds. Defaults to 5000 milliseconds.

Returns

array
array

An array with the following fields:

value
string

The value if the transaction was successful

error
string

(Optional) The error if the transaction failed
