}

Transaction related functions for the EthApiServer trait in the eth_ namespace.

This includes utilities for transaction tracing, transacting and inspection.

Async functions that are spawned onto the BlockingTaskPool begin with spawn_

Calls

There are subtle differences between when transacting TransactionRequest:

The endpoints eth_call and eth_estimateGas and eth_createAccessList should always disable the base fee check in the EnvWithHandlerCfg.

The behaviour for tracing endpoints is not consistent across clients. Geth also disables the basefee check for tracing: https://github.com/ethereum/go-ethereum/blob/bc0b87ca196f92e5af49bd33cc190ef0ec32b197/eth/tracers/api.go#L955-L955 Erigon does not: https://github.com/ledgerwatch/erigon/blob/aefb97b07d1c4fd32a66097a24eddd8f6ccacae0/turbo/transactions/tracing.go#L209-L209

See also https://github.com/paradigmxyz/reth/issues/6240

This implementation follows the behaviour of Geth and disables the basefee check for tracing.

Required Methods

fn sign( &self, account: Address, message: Bytes, ) -> impl Future<Output = Result<Bytes, Self::Error>> + Send

Signs given message. Returns the signature.

fn sign_transaction( &self, request: TransactionRequest, ) -> impl Future<Output = Result<Bytes, Self::Error>> + Send

Signs a transaction request using the given account in request Returns the EIP-2718 encoded signed transaction.

fn sign_typed_data( &self, data: &TypedData, account: Address, ) -> Result<Bytes, Self::Error>

Encodes and signs the typed data according EIP-712. Payload must implement Eip712 trait.

fn find_signer( &self, account: &Address, ) -> Result<Box<dyn EthSigner>, Self::Error>

Returns the signer for the given account, if found in configured signers.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
