Struct MultiSmartContractSignatureVerifier 

pub struct MultiSmartContractSignatureVerifier { /* private fields */ }

Routes signature checks to a verifier selected by chain ID.

Each configured key is an eip155:<chain> identifier. A missing route is a retryable configuration/provider error so callers can distinguish it from a bad signature.

Implementations

impl MultiSmartContractSignatureVerifier

pub fn new(urls: HashMap<String, Url>) -> Result<Self, VerifierError>

Build RPC verifiers from chain IDs and endpoint URLs.

URL parsing and provider construction errors are returned before a partially configured verifier is created.

pub fn new_providers( providers: HashMap<String, DynProvider>, ) -> Result<Self, VerifierError>

Build RPC verifiers from already-created providers.

The provider map is consumed and keyed by the caller’s chain IDs.

pub fn new_from_env() -> Result<Self, VerifierError>

Load the default chain routes, apply environment overrides, and add Anvil.

pub fn new_from_file(path: impl AsRef<Path>) -> Result<Self, VerifierError>

Load chain routes from a JSON file.

The file must contain a map from chain ID to URL. Environment upgrades are not applied by this constructor.

pub fn upgrade(self) -> Result<Self, VerifierError>

Replace default routes with environment overrides when present.

This also registers the configured Anvil endpoint. A malformed chain ID or endpoint prevents the verifier from being returned.

pub fn add_verifier( &mut self, id: String, url: String, ) -> Result<(), VerifierError>

Add or replace one chain verifier backed by an RPC URL.

pub fn add_anvil(&mut self, url: String) -> Result<(), VerifierError>

Add or replace the local Anvil verifier route.
