This trait is used to obtain Ethereum-related data.

Required Methods

fn account_code_at(&self, at: Block::Hash, address: Address) -> Option<Vec<u8>>

Return the code with the given address.

fn account_storage_at( &self, at: Block::Hash, address: Address, index: U256, ) -> Option<H256>

Return the storage data with the given address and storage index.

fn current_block(&self, at: Block::Hash) -> Option<BlockV3>

Return the current ethereum block.

fn current_receipts(&self, at: Block::Hash) -> Option<Vec<ReceiptV4>>

Return the current ethereum transaction receipt.

fn current_transaction_statuses( &self, at: Block::Hash, ) -> Option<Vec<TransactionStatus>>

Return the current ethereum transaction status.

fn elasticity(&self, at: Block::Hash) -> Option<Permill>

Return the elasticity multiplier at the given post-eip1559 block.

fn is_eip1559(&self, at: Block::Hash) -> bool

Return true if the request block is post-eip1559.
