Evm¶

Calls¶

call¶

Issue an EVM call operation. This is similar to a message call transaction in Ethereum.

target	`H160`
input	`Vec<u8>`
value	`U256`

max_priority_fee_per_gas	`Option<U256>`
nonce	`Option<U256>`
access_list	`Vec<(H160, Vec<H256>)>`

create¶

Issue an EVM create operation. This is similar to a contract creation transaction in Ethereum.

Python¶

call = substrate.compose_call(
    'Evm', 'create', {
    'access_list': [
        ('[u8; 20]', ['scale_info::9']),
    ],
    'gas_limit': 'u64',
    'init': 'Bytes',

    'max_priority_fee_per_gas': (
        None,
        'scale_info::111',
    ),

max_priority_fee_per_gas	`Option<U256>`
nonce	`Option<U256>`
access_list	`Vec<(H160, Vec<H256>)>`

Python¶

call = substrate.compose_call(
    'Evm', 'create2', {
    'access_list': [
