Implementations§

§

impl NamedChain

pub fn as_str(&self) -> &'static str

Returns the string representation of the chain.

pub const fn is_ethereum(&self) -> bool

Returns true if this chain is Ethereum or an Ethereum testnet.

pub const fn is_optimism(self) -> bool

Returns true if the chain contains Optimism configuration.

pub const fn is_arbitrum(self) -> bool

Returns true if the chain contains Arbitrum configuration.

pub const fn average_blocktime_hint(self) -> Option<Duration>

Returns the chain’s average blocktime, if applicable.

It can be beneficial to know the average blocktime to adjust the polling of an HTTP provider for example.

Note: this is not an accurate average, but is rather a sensible default derived from blocktime charts such as Etherscan’s or Polygonscan’s.

§Examples
use alloy_chains::NamedChain;
use std::time::Duration;

assert_eq!(NamedChain::Mainnet.average_blocktime_hint(), Some(Duration::from_millis(12_000)),);
assert_eq!(NamedChain::Optimism.average_blocktime_hint(), Some(Duration::from_millis(2_000)),);

pub const fn is_legacy(self) -> bool

Returns whether the chain implements EIP-1559 (with the type 2 EIP-2718 transaction type).

§Examples
use alloy_chains::NamedChain;

assert!(!NamedChain::Mainnet.is_legacy());
assert!(NamedChain::Celo.is_legacy());

pub const fn supports_shanghai(self) -> bool

Returns whether the chain supports the Shanghai hardfork.

pub const fn is_testnet(self) -> bool

Returns whether the chain is a testnet.

pub const fn native_currency_symbol(self) -> Option<&'static str>

Returns the symbol of the chain’s native currency.

pub const fn etherscan_urls(self) -> Option<(&'static str, &'static str)>

Returns the chain’s blockchain explorer and its API (Etherscan and Etherscan-like) URLs.

Returns (API_URL, BASE_URL).

All URLs have no trailing /

§Examples
use alloy_chains::NamedChain;

assert_eq!(
    NamedChain::Mainnet.etherscan_urls(),
    Some(("https://api.etherscan.io/api", "https://etherscan.io"))
);
assert_eq!(
    NamedChain::Avalanche.etherscan_urls(),
    Some(("https://api.snowtrace.io/api", "https://snowtrace.io"))
);
assert_eq!(NamedChain::AnvilHardhat.etherscan_urls(), None);

pub const fn etherscan_api_key_name(self) -> Option<&'static str>

Returns the chain’s blockchain explorer’s API key environment variable’s default name.

§Examples
use alloy_chains::NamedChain;

assert_eq!(NamedChain::Mainnet.etherscan_api_key_name(), Some("ETHERSCAN_API_KEY"));
assert_eq!(NamedChain::AnvilHardhat.etherscan_api_key_name(), None);

pub fn etherscan_api_key(self) -> Option<String>

Available on crate feature std only.

Returns the chain’s blockchain explorer’s API key, from the environment variable with the name specified in etherscan_api_key_name.

§Examples
use alloy_chains::NamedChain;

let chain = NamedChain::Mainnet;
std::env::set_var(chain.etherscan_api_key_name().unwrap(), "KEY");
assert_eq!(chain.etherscan_api_key().as_deref(), Some("KEY"));

pub fn public_dns_network_protocol(self) -> Option<String>

Returns the address of the public DNS node list for the given chain.

See also https://github.com/ethereum/discv4-dns-lists.

pub const fn wrapped_native_token(self) -> Option<Address>

Returns the address of the most popular wrapped native token address for this chain, if it exists.

Example:

use alloy_chains::NamedChain;
use alloy_primitives::address;

let chain = NamedChain::Mainnet;
assert_eq!(
    chain.wrapped_native_token(),
    Some(address!("C02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2"))
);
