Struct ethers_middleware::gas_escalator::GasEscalatorMiddleware

pub struct GasEscalatorMiddleware<M> { /* private fields */ }

A Gas escalator allows bumping transactions’ gas price to avoid getting them stuck in the memory pool.

GasEscalator runs a background task which monitors the blockchain for tx confirmation, and bumps fees over time if txns do not occur. This task periodically loops over a stored history of sent transactions, and checks if any require fee bumps. If so, it will resend the same transaction with a higher fee.

Using GasEscalatorMiddleware::new will create a new instance of the background task. Using GasEscalatorMiddleware::clone will crate a new instance of the middleware, but will not create a new background task. The background task is shared among all clones.

Footgun

If you drop the middleware, the background task will be dropped as well, and any transactions you have sent will stop escalating. We recommend holding an instance of the middleware throughout your application’s lifecycle, or leaking an Arc of it so that it is never dropped.

Outstanding issue

This task is fallible, and will stop if the provider’s connection is lost. If this happens, the middleware will become unable to properly escalate gas prices. Transactions will still be dispatched, but no fee-bumping will happen. This will also cause a memory leak, as the middleware will keep appending to the list of transactions to escalate (and nothing will ever clear that list).

We intend to fix this issue in a future release.

Example

use ethers_providers::{Provider, Http};
use ethers_middleware::{
    gas_escalator::{GeometricGasPrice, Frequency, GasEscalatorMiddleware},
    gas_oracle::{GasNow, GasCategory, GasOracleMiddleware},
};
use std::{convert::TryFrom, time::Duration, sync::Arc};

let provider = Provider::try_from("http://localhost:8545")
    .unwrap()
    .interval(Duration::from_millis(2000u64));

let provider = {
    let escalator = GeometricGasPrice::new(5.0, 10u64, None::<u64>);
    GasEscalatorMiddleware::new(provider, escalator, Frequency::PerBlock)
};

// ... proceed to wrap it in other middleware
let gas_oracle = GasNow::new().category(GasCategory::SafeLow);
let provider = GasOracleMiddleware::new(provider, gas_oracle);

where 'life0: 'async_trait, T: 'async_trait + Into<BlockNumber> + Send + Sync, Self: 'async_trait,

Returns all receipts for that block. Must be done on a parity node.

fn fee_history<'life0, 'life1, 'async_trait, T>( &'life0 self, block_count: T, last_block: BlockNumber, reward_percentiles: &'life1 [f64] ) -> Pin<Box<dyn Future<Output = Result<FeeHistory, Self::Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, T: 'async_trait + Into<U256> + Serialize + Send + Sync, Self: 'async_trait,

Query the node for a FeeHistory object. This objct contains information about the EIP-1559 base fee in past blocks, as well as gas utilization within those blocks.

fn create_access_list<'life0, 'life1, 'async_trait>( &'life0 self, tx: &'life1 TypedTransaction, block: Option<BlockId> ) -> Pin<Box<dyn Future<Output = Result<AccessListWithGasUsed, Self::Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Query the node for an EIP-2930 Access List.
