Expand description

Trait defining the interface for EVM blockchain interactions.

This trait provides methods for common blockchain operations like querying balances, sending transactions, and getting network state.

Required Methods§

Source

fn get_balance<'life0, 'life1, 'async_trait>( &'life0 self, address: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<U256>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Gets the balance of an address in the native currency.

§Arguments
  • address - The address to query the balance for
Source

fn get_block_number<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<u64>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Gets the current block number of the chain.

Source

fn estimate_gas<'life0, 'life1, 'async_trait>( &'life0 self, tx: &'life1 EvmTransactionData, ) -> Pin<Box<dyn Future<Output = Result<u64>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,
