These are commonly used addresses among Ethereum-like chains.
This is the primary usage for the address book. Currently the method on()
returns Address
but in the future as other chains are added where certain tokens do not exist then the return type will be Option<Address>
use plutonium_address_book::AddressBook;
let weth = AddressBook::Weth.on(NamedChain::Mainnet);
For a more certain approach
let weth = plutonium_address_book::mainnet::WETH;
