Available on crate feature cmd only.

Anvil’s EVM related arguments.

Fields

fork_url: Option<ForkUrl>

Fetch state over a remote endpoint instead of starting from an empty state.

If you want to fetch state from a specific block number, add a block number like http://localhost:8545@1400000 or use the --fork-block-number argument.

fork_headers: Vec<String>

Headers to use for the rpc client, e.g. “User-Agent: test-agent”

See –fork-url.

fork_request_timeout: Option<u64>

Timeout in ms for requests sent to remote JSON-RPC server in forking mode.

Default value 45000

fork_request_retries: Option<u32>

Number of retry requests for spurious networks (timed out requests)

Default value 5

fork_block_number: Option<u64>

Fetch state from a specific block number over a remote endpoint.

See –fork-url.

fork_transaction_hash: Option<B256>

Fetch state from a specific transaction hash over a remote endpoint.

See –fork-url.

fork_retry_backoff: Option<u64>

Initial retry backoff on encountering errors.

See –fork-url.

fork_chain_id: Option<Chain>

Specify chain id to skip fetching it from remote endpoint. This enables offline-start mode.

You still must pass both --fork-url and --fork-block-number, and already have your required state cached on disk, anything missing locally would be fetched from the remote.

compute_units_per_second: Option<u64>

Sets the number of assumed available compute units per second for this provider

default value: 330

See also –fork-url and https://docs.alchemy.com/reference/compute-units#what-are-cups-compute-units-per-second

no_rate_limit: bool

Disables rate limiting for this node’s provider.

default value: false

See also –fork-url and https://docs.alchemy.com/reference/compute-units#what-are-cups-compute-units-per-second

no_storage_caching: bool

Explicitly disables the use of RPC caching.

All storage slots are read entirely from the endpoint.

This flag overrides the project’s configuration file.

See –fork-url.

gas_limit: Option<u128>

The block gas limit.

disable_block_gas_limit: bool

Disable the call.gas_limit <= block.gas_limit constraint.

code_size_limit: Option<usize>

EIP-170: Contract code size limit in bytes. Useful to increase this because of tests. To disable entirely, use --disable-code-size-limit. By default, it is 0x6000 (~25kb).

disable_code_size_limit: bool

Disable EIP-170: Contract code size limit.

gas_price: Option<u128>

The gas price.

block_base_fee_per_gas: Option<u64>

The base fee in a block.

disable_min_priority_fee: bool

Disable the enforcement of a minimum suggested priority fee.

chain_id: Option<Chain>

The chain ID.

steps_tracing: bool

Enable steps tracing used for debug calls returning geth-style traces

disable_console_log: bool

Disable printing of console.log invocations to stdout.

auto_impersonate: bool

Enables automatic impersonation on startup. This allows any transaction sender to be simulated as different accounts, which is useful for testing contract behavior.

optimism: bool

Run an Optimism chain

disable_default_create2_deployer: bool

Disable the default create2 deployer

memory_limit: Option<u64>

The memory limit per EVM execution in bytes.

odyssey: bool

Enable Odyssey features

Implementations

impl AnvilEvmArgs

Resolves an alias passed as fork-url to the matching url defined in the rpc_endpoints section of the project configuration file. Does nothing if the fork-url is not a configured alias.

pub fn resolve_rpc_alias(&mut self)

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.
