Struct SolanaSigner 

pub struct SolanaSigner { /* private fields */ }

Solana Ed25519 signer.

Implementations

impl SolanaSigner

pub fn address(&self) -> String

Return the Solana address as a Base58-encoded string.

Solana addresses are simply the Base58 encoding of the 32-byte Ed25519 public key.

pub fn public_key_bytes_32(&self) -> [u8; 32]

Return the 32-byte public key as a fixed-size array.

impl SolanaSigner

pub fn scalar_bytes(&self) -> Zeroizing<Vec<u8>>

Export the clamped Ed25519 scalar (first 32 bytes of SHA-512(seed), clamped).

⚠️ Advanced use only — for MPC, threshold signing, or key derivation. The scalar is the actual private scalar used in Ed25519 signing.

Trait Implementations

impl Drop for SolanaSigner

fn drop(&mut self)

Executes the destructor for this type.

impl KeyPair for SolanaSigner

fn from_keypair_bytes(keypair: &[u8]) -> Result<Self, SignerError>

Import from Solana’s 64-byte keypair format (seed ∥ pubkey). Validates that the derived public key matches bytes[32..64] using constant-time comparison to prevent timing side-channels.

fn keypair_bytes(&self) -> Zeroizing<Vec<u8>>

Export as Solana’s 64-byte keypair (seed ∥ pubkey).

fn generate() -> Result<Self, SignerError>

Generate a new random key pair using OS entropy (CSPRNG).

fn from_bytes(private_key: &[u8]) -> Result<Self, SignerError>

Reconstruct a key pair from raw private key bytes (32 bytes).

fn private_key_bytes(&self) -> Zeroizing<Vec<u8>>

Export the private key as auto-zeroizing bytes. The returned Zeroizing<Vec<u8>> will scrub the memory on drop.

impl Signer for SolanaSigner

fn sign_prehashed(&self, digest: &[u8]) -> Result<SolanaSignature, SignerError>

⚠️ Not Actually Pre-Hashed

Ed25519 hashes internally per RFC 8032. This method is identical to sign() — the digest parameter is treated as a raw message, not a pre-computed hash. Passing a SHA-256 digest here will sign the digest bytes as a message, NOT use them as a pre-computed hash.

Provided for trait consistency only.

type Signature = SolanaSignature

The signature type produced by this signer.

type Error = SignerError

The error type returned on failure.

fn sign(&self, message: &[u8]) -> Result<SolanaSignature, SignerError>

Sign a raw message. The implementation applies chain-specific hashing internally (e.g., Keccak-256 for Ethereum, double-SHA-256 for Bitcoin).

fn public_key_bytes(&self) -> Vec<u8>

Return the public key as bytes (compressed format where applicable).

fn public_key_bytes_uncompressed(&self) -> Vec<u8>

Return the public key in uncompressed format.
