Expand description

Represents a minimal EVM transaction. Currently, EIP-1559, EIP-4844, and EIP-7702 support dynamic fees. We call these transactions “dynamic fee transactions”. We call non dynamic fee transactions(EIP-155, EIP-2930) “legacy fee transactions”.

Required Methods§

fn chain_id(&self) -> Option<u64>

Get chain_id.

fn nonce(&self) -> u64

Get nonce.

fn gas_limit(&self) -> u64

Get gas_limit.

fn gas_price(&self) -> Option<u128>

Get gas_price.

fn max_fee_per_gas(&self) -> u128

For dynamic fee transactions returns the maximum fee per gas the caller is willing to pay.

For legacy fee transactions this is gas_price.

This is also commonly referred to as the “Gas Fee Cap”.

fn max_priority_fee_per_gas(&self) -> Option<u128>

For dynamic fee transactions returns the Priority fee the caller is paying to the block author.

This will return None for legacy fee transactions

fn max_fee_per_blob_gas(&self) -> Option<u128>

Max fee per blob gas for EIP-4844 transaction.

Returns None for non-eip4844 transactions.

This is also commonly referred to as the “Blob Gas Fee Cap”.

fn priority_fee_or_price(&self) -> u128

Return the max priority fee per gas if the transaction is a dynamic fee transaction, and otherwise return the gas price.

§Warning

This is different than the max_priority_fee_per_gas method, which returns None for legacy fee transactions.

fn effective_gas_price(&self, base_fee: Option<u64>) -> u128

Returns the effective gas price for the given base fee.

If the transaction is a legacy fee transaction, the gas price is returned.

fn is_dynamic_fee(&self) -> bool

Returns true if the transaction supports dynamic fees.

fn kind(&self) -> TxKind

Returns the transaction kind.

fn is_create(&self) -> bool

Returns true if the transaction is a contract creation. We don’t provide a default implementation via kind as it copies the 21-byte TxKind for this simple check. A proper implementation shouldn’t allocate.
