--config-out <OUT_FILE>
Writes output of `anvil` as json to user-specified file
--derivation-path <DERIVATION_PATH>
Sets the derivation path of the child key to be derived.
[default: m/44'/60'/0'/0/]
--dump-state <PATH>
Dump the state and block environment of chain on exit to the given file.
If the value is a directory, the state will be written to `<VALUE>/state.json`.
-h, --help
Print help (see a summary with '-h')
--hardfork <HARDFORK>
The EVM hardfork to use.
Choose the hardfork by name, e.g. `shanghai`, `paris`, `london`, etc... [default: latest]
--init <PATH>
Initialize the genesis block with the given `genesis.json` file
--ipc [<PATH>]
Launch an ipc server at the given path or default path = `/tmp/anvil.ipc`
[aliases: ipcpath]
--load-state <PATH>
Initialize the chain from a previously saved state snapshot
-m, --mnemonic <MNEMONIC>
BIP39 mnemonic phrase used for generating accounts. Cannot be used if `mnemonic_random` or
`mnemonic_seed` are used
--mnemonic-random [<MNEMONIC_RANDOM>]
Automatically generates a BIP39 mnemonic phrase, and derives accounts from it. Cannot be
used with other `mnemonic` options You can specify the number of words you want in the
mnemonic. [default: 12]
--mnemonic-seed-unsafe <MNEMONIC_SEED>
Generates a BIP39 mnemonic phrase from a given seed Cannot be used with other `mnemonic`
options
CAREFUL: this is NOT SAFE and should only be used for testing. Never use the private keys
generated in production.
--no-mining
Disable auto and interval mining, and mine on demand instead
[aliases: no-mine]
--order <ORDER>
How transactions are sorted in the mempool
[default: fees]
-p, --port <NUM>
Port number to listen on
[default: 8545]
--prune-history [<PRUNE_HISTORY>]
Don't keep full chain history. If a number argument is specified, at most this number of
states is kept in memory
-s, --state-interval <SECONDS>
Interval in seconds at which the state and block environment is to be dumped to disk.
See --state and --dump-state
--silent
Don't print anything on startup and don't print logs
--slots-in-an-epoch <SLOTS_IN_AN_EPOCH>
Slots in an epoch
[default: 32]
--state <PATH>
This is an alias for both --load-state and --dump-state.
It initializes the chain with the state and block environment stored at the file, if it
exists, and dumps the chain's state on exit.
--timestamp <NUM>
The timestamp of the genesis block
--transaction-block-keeper <TRANSACTION_BLOCK_KEEPER>
Number of blocks with transactions to keep in memory
-V, --version
Print version
Server options:
--allow-origin <ALLOW_ORIGIN>
Set the CORS allow_origin
[default: *]
--host <IP_ADDR>
The hosts the server will listen on
[env: ANVIL_IP_ADDR=]
[default: 127.0.0.1]
--no-cors
Disable CORS
Fork config:
--compute-units-per-second <CUPS>
Sets the number of assumed available compute units per second for this provider
default value: 330
See --fork-url. See also,
https://docs.alchemy.com/reference/compute-units#what-are-cups-compute-units-per-second
-f, --fork-url <URL>
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.
[aliases: rpc-url]
--fork-block-number <BLOCK>
Fetch state from a specific block number over a remote endpoint.
See --fork-url.
--fork-chain-id <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.
--fork-header <HEADERS>
Headers to use for the rpc client, e.g. "User-Agent: test-agent"
See --fork-url.
--fork-retry-backoff <BACKOFF>
Initial retry backoff on encountering errors.
See --fork-url.
--no-rate-limit
Disables rate limiting for this node's provider.
default value: false
See --fork-url. See also,
https://docs.alchemy.com/reference/compute-units#what-are-cups-compute-units-per-second
[aliases: no-rpc-rate-limit]
--no-storage-caching
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.
--retries <retries>
Number of retry requests for spurious networks (timed out requests)
Default value 5
--timeout <timeout>
Timeout in ms for requests sent to remote JSON-RPC server in forking mode.
Default value 45000
Environment config:
--block-base-fee-per-gas <FEE>
The base fee in a block
[aliases: base-fee]
--chain-id <CHAIN_ID>
The chain ID
--code-size-limit <CODE_SIZE>
EIP-170: Contract code size limit in bytes. Useful to increase this because of tests. By
default, it is 0x6000 (~25kb)
--disable-block-gas-limit
Disable the `call.gas_limit <= block.gas_limit` constraint
--gas-limit <GAS_LIMIT>
The block gas limit
--gas-price <GAS_PRICE>
The gas price
EVM options:
--auto-impersonate
Enable autoImpersonate on startup
[aliases: auto-impersonate]
--disable-default-create2-deployer
Disable the default create2 deployer
[aliases: no-create2]
--memory-limit <MEMORY_LIMIT>
The memory limit per EVM execution in bytes
--optimism
Run an Optimism chain
[aliases: optimism]
--steps-tracing
Enable steps tracing used for debug calls returning geth-style traces
[aliases: tracing]
