40/// Transaction related functions for the [`EthApiServer`](crate::EthApiServer) trait in
41/// the `eth_` namespace.
42///
43/// This includes utilities for transaction tracing, transacting and inspection.
44///
45/// Async functions that are spawned onto the
46/// [`BlockingTaskPool`](reth_tasks::pool::BlockingTaskPool) begin with `spawn_`
47///
48/// ## Calls
49///
50/// There are subtle differences between when transacting [`RpcTxReq`]:
51///
52/// The endpoints `eth_call` and `eth_estimateGas` and `eth_createAccessList` should always
53/// __disable__ the base fee check in the [`CfgEnv`](revm::context::CfgEnv).
54///
55/// The behaviour for tracing endpoints is not consistent across clients.
56/// Geth also disables the basefee check for tracing: <https://github.com/ethereum/go-ethereum/blob/bc0b87ca196f92e5af49bd33cc190ef0ec32b197/eth/tracers/api.go#L955-L955>
57/// Erigon does not: <https://github.com/ledgerwatch/erigon/blob/aefb97b07d1c4fd32a66097a24eddd8f6ccacae0/turbo/transactions/tracing.go#L209-L209>
58///
59/// See also <https://github.com/paradigmxyz/reth/issues/6240>
60///
61/// This implementation follows the behaviour of Geth and disables the basefee check for tracing.
