Struct WalletsBuilder 

pub struct WalletsBuilder { /* private fields */ }

Builds a Wallets. Everything the module cannot decide for a venture — which domain its messages are bound to, where its entropy comes from, whether it can check a contract wallet — is set here.

Implementations

impl WalletsBuilder

pub fn new() -> Self

The defaults: no domain, no entropy source, Ethereum mainnet, a ten-minute nonce and no contract verifier.

pub fn domain(self, domain: impl Into<String>) -> Self

The domain every SIWE/SIWS message must name. This is the phishing defence, so it is required: a message minted for another site is refused rather than verified.

pub fn uri(self, uri: impl Into<String>) -> Self

The URI field of the messages, the page the signer is being sent back to. Defaults to https://<domain>.

pub fn statement(self, statement: impl Into<String>) -> Self

The Statement line — the words the person reads before signing. This is the one line that reaches a human, so it should say what is about to happen in the plainest words available.

pub fn chain_id(self, chain_id: impl Into<String>) -> Self

The EVM chain id the messages carry. Defaults to DEFAULT_EVM_CHAIN_ID.

pub fn nonce_ttl(self, ttl: Duration) -> Self

How long a nonce stays usable. Clamped to at least one second and at most MAX_NONCE_TTL.

pub fn random(self, random: impl RandomBytes + 'static) -> Self

Sets the entropy source nonces are drawn from. Required: core carries no CSPRNG, so the venture supplies one (ADR 0002).

pub fn contract_verifier( self, verifier: impl ContractSignatureVerifier + 'static, ) -> Self

Sets the EIP-1271 contract-wallet verifier. Left unset the module serves EOAs only; a smart-contract wallet then fails with wallets/signature-invalid rather than hanging on a chain call.

pub fn build(self) -> Wallets

Builds the module. A blank uri with a domain set becomes https://<domain>, so the common composition does not have to repeat the domain twice.

Trait Implementations

impl Default for WalletsBuilder

fn default() -> Self

Returns the “default value” for a type.
