Crate signer 

Multi-chain transaction signer (umbrella).

Layers

L0  signer-primitives   curves + SignDigest / SignOutput
L1  signer-{chain}      protocol preimage + wire (this crate re-exports)
L2  signer-cli          ops UX
──  kobe                HD only — use feature `kobe` + FromDerived

Schemes: secp256k1 ECDSA, BIP-340 Schnorr, Ed25519. Framing (EIP-191, BIP-137, …) stays in chain crates — this is not a “hash-only” strip.

Usage

use signer::{SignMessage, evm};

let s = evm::Signer::from_hex("0x...").unwrap();
let sig = s.sign_message(b"hello").unwrap();

Modules

prelude

Prelude that imports every capability trait plus SignOutput and SignError in one glob.

v_encoding

Canonical recovery-id / message-header offsets for secp256k1 ECDSA.

Structs

Digest32

32-byte digest, event id, or fixed-length message blob.

SecretKey32

Owned 32-byte secret key material (zeroized on drop).

Enums

SignError

Errors from signing operations.

SignOutput

Signature output across every scheme the workspace supports.

SignatureScheme

Wire-level signature scheme discriminant.

Traits

EncodeSignedTransaction

Optional: assemble signed wire bytes from (unsigned_tx, SignOutput).

ExtractSignableBytes

Optional: extract the signable portion from a fully serialized transaction.

FromDerived

Construct a signer from a kobe-derived account.

FromSecretKey

Construct a signer from raw secret-key material.

SignDigest

Mandatory 32-byte signing surface for every chain Signer.

SignMessage

Opt-in capability: sign an off-chain message with the chain’s convention.
