Struct Wallet 

pub struct Wallet { /* private fields */ }

An owning secp256k1 wallet.

Construction is explicit (from_bytes / from_hex / random_for_testing). The inner SigningKey zeroizes on drop automatically. Debug does not reveal the key material — only the derived address.

Implementations

impl Wallet

pub fn from_bytes(bytes: [u8; 32]) -> Result<Wallet, ClientError>

Construct from a 32-byte secret scalar.

Errors

Returns ClientError::InvalidKey if the bytes are not a valid secp256k1 scalar (zero or ≥ curve order).

pub fn from_hex(s: &str) -> Result<Wallet, ClientError>

Construct from a hex private key (with or without 0x prefix).

Errors

Returns ClientError::InvalidKey on wrong length / non-hex / not a valid scalar.

pub const fn address(&self) -> Address

Derived 20-byte EVM address.

impl Wallet

pub fn sign_eip712<T>(&self, msg: &T) -> Result<Signature, ClientError>

where T: Eip712,

Sign an EIP-712 typed message and produce a 65-byte signature.

The signing is deterministic (RFC-6979 nonces).

Errors

Returns ClientError::Signature only if the k256 prehash signer fails, which is extremely rare (essentially never in practice for valid keys + 32-byte digests).

pub fn sign_digest(&self, digest: &[u8; 32]) -> Result<Signature, ClientError>

Sign an arbitrary 32-byte digest with the wallet key.

Lower-level than Wallet::sign_eip712 — use only when you already have the EIP-712 digest computed externally.

Errors

See Wallet::sign_eip712.

Trait Implementations

impl Clone for Wallet

fn clone(&self) -> Wallet

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Wallet

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
